JST SH1.0 Connector Complete Guide: Specs, Pin Counts, Dual-Row Options & the KONNRA KR1000 Equivalent

KR1000 Series Single Row SH Connector

Quick answer: The JST SH 1.0 connector is a 1.0mm pitch, single-row, wire-to-board crimp connector with SMD mounting and a side latch. It is rated 1A AC/DC at 50V, accepts AWG #32 to #28 wire (0.032–0.081mm²) with insulation O.D. of 0.4–0.8mm, and is available in 2 to 16 and 20 circuits. The KONNRA KR1000 series is documented as its cross-reference equivalent — and extends the family to a dual-row version from 2×4 to 2×30 circuits (8–60 contacts) that the JST SH does not offer.

The JST SH was the first 1.0mm pitch crimp-style connector in the industry, and it remains the default interconnect wherever board space is the binding constraint: micro FPV drones, wearables, compact IoT sensor boards, camera modules, and dense multi-board assemblies. That popularity creates a specific sourcing problem. Because the SH is so widely used, it is also widely mis-documented. Distributor listings and supplier blogs routinely publish the wrong insulation resistance (off by 10×), the wrong wire insulation diameter, and the wrong housing material — and those errors propagate because nobody checks them against the original datasheet. This guide is built the other way around: every JST figure below is taken from JST's published SH series documentation, every KONNRA figure from KONNRA's product documentation, and every disagreement between the two is called out explicitly rather than smoothed over.

A note on naming: this part appears as JST SH1.0 connector, JST SH 1.0, SH1.0, SH 1.0mm, and "1.0mm JST connector" in listings and searches. They all refer to the same JST SH series. This guide also cross-references the KONNRA KR1000 series, which KONNRA documents as the SH 1.0 equivalent.

What Is the JST SH 1.0 Connector?

The JST SH is a 1.0mm pitch, single-row, wire-to-board connector that terminates by crimping a wire into a terminal, which then clicks into a housing that latches onto an SMD header on the PCB. A complete connection uses three parts:

  • SHR housing — the wire-side plug, from 2 to 20 circuits
  • SMD header — the PCB-side shrouded header, top entry or side entry
  • SSH-003T terminal — the crimp contact, for AWG #32 to #28 wire

Key characteristics:

  • 1.0mm pitch — the smallest pitch in the mainstream JST wire-to-board lineup
  • SMD mounting only — there is no through-hole SH
  • 1A per contact at 50V AC/DC — rated with AWG #28 wire
  • Low profile — approximately 2.95mm mounting height for the side-entry type
  • Side latch — the housing is polarized and latches in one orientation only
  • Vacuum-placement friendly — the header shroud has no holes, so pick-and-place nozzle vacuum cannot leak through it
  • Operator-release protrusions — the housing has tabs at both ends so it can be unplugged without pulling on the wires
  • Shared header with the SR series — JST documents the SH shrouded header as compatible with SR series IDC sockets, so the same PCB footprint can be used for either termination method
  • Gold plating available on request — standard finish is tin over copper alloy

Crimp terminal SSH-003T-P0.2-H (AWG #32–#28, tin-plated copper alloy) KR1000 Terminal
Compatible IDC socket on the same header SR series IDC socket

Reading the part numbers. JST encodes the circuit count in the position digits: `SHR-04V-S-B` is the 4-circuit housing, `BM06B-SRSS-TB` is the 6-circuit top-entry header, `SM06B-SRSS-TB` is the 6-circuit side-entry header. The `-B` suffix on the housing denotes the version with protrusions — the tabs that let an operator unplug it without gripping the wires. The `SSH-003T` terminal is a single part number covering the whole AWG #32–#28 range, so the wire size is set by the crimp, not by a different terminal. One part number, two termination methods. JST documents the SH shrouded header as compatible with SR series IDC sockets. That means the same SMD footprint can be built with crimp termination (SH) or insulation displacement termination (SR). If a programme switches between the two — for example, moving from bench crimping to factory-built assemblies — the PCB does not have to change. Confirm this against your specific header part number before freezing a design around it.

Both families are SMD-only. Neither the JST SH nor the KONNRA KR1000 offers a through-hole version. A design that assumes a DIP footprint cannot be served by either.

Specification differences worth verifying before you cross-reference

Five points matter more than the rest, because these are the values that circulate incorrectly. 1\. Insulation resistance is 100MΩ, not 1,000MΩ. JST's SH documentation states 100MΩ minimum. Several widely-read supplier guides publish 1,000MΩ — a ten-fold difference that appears to have been copied from a different series. The KONNRA KR1000 is documented at the same 100MΩ minimum as JST. If a test specification in your programme was written from a third-party listing, it may be asking for something the genuine part does not promise. 2\. The wire insulation range is 0.4–0.8mm, not 0.5–0.9mm. JST specifies the applicable insulation O.D. as 0.4mm to 0.8mm, alongside a conductor range of AWG #32 to #28 (0.032–0.081mm²). The KR1000 is documented at the identical 0.4–0.8mm. A harness drawing that accepts 0.9mm insulation is out of the SH's specified range. 3\. Housing material is PBT (header base PA, heat-resistant), not PA66. JST documents the SHR housing as PBT, natural white, and the header's base housing as PA with heat-resistant grade. PA66 is frequently quoted in third-party tables but is not what JST specifies for this series. KONNRA documents the KR1000 in PBT / LCP / PA9T, UL94. 4\. The terminal is tin-plated copper alloy by default — gold is a special order. JST lists SSH-003T-P0.2-H as copper alloy, tin-plated, with gold plating available on request. Several listings describe the terminal as "gold-plated" as standard. If your programme requires gold, that is a specification to state explicitly and confirm, not to assume. 5\. Contact resistance — read the second number too. JST publishes 30mΩ max initial *and* 50mΩ max after environmental tests. Third-party tables usually quote only the 30mΩ figure, which understates the end-of-life condition. The KONNRA KR1000 is documented at 20mΩ max. If contact resistance is a critical parameter for your application, ask both suppliers for the test data rather than comparing single numbers. Why this matters commercially. These are not academic differences. A wrong insulation resistance or insulation diameter in a harness specification shows up as a failed incoming inspection or an intermittent field failure — after tooling and cable assemblies have been committed. The cheapest time to catch it is during cross-reference, which is exactly what a designed-in verification step is for.

The Option the JST SH Does Not Have: Dual-Row 1.0mm

Here is where the KR1000 diverges from the JST SH in a way that matters to design engineers. JST SH is single row only. The housing range ends at 20 circuits in one row, and the header range stops at 16 positions for top entry and 20 for side entry. The KONNRA KR1000 adds a dual-row version covering 2×4 to 2×30 — that is 8 to 60 contacts — at the same 1.0mm pitch, in the same product family.

  JST SH 1.0 KONNRA KR1000
Single row 2 – 16, 20 circuits 2 – 20 circuits
Dual row Not available 2×4 – 2×30 (8 – 60 contacts)
Voltage 50V AC/DC 50V
Current 1A (AWG #28) 1A

When this decides your design. Three situations come up repeatedly:

  • You need more than 20 signals at 1.0mm pitch. With the JST SH, the only route is multiple single-row connectors — which costs board area, takes additional mating operations, and creates more points of failure. A dual-row part carries the same signals in one connector.
  • You are multiplexing a sensor array or a display interface. Dual-row 1.0mm handles 30–60 lines in a footprint that single-row parts cannot match at this pitch.
  • You want one connector family across a product range. A single-row and dual-row family sharing the same pitch, plating, and termination means one crimp process, one set of tooling, and one supplier relationship instead of two.

If your design is currently constrained by single-row 1.0mm circuit count, that constraint is worth re-checking — it may not exist anymore.

Mounting Height and Board Design

At 1.0mm pitch, the connector decision is often really a mechanical decision. Four practical points: Mounted height. JST documents the side-entry SH at approximately 2.95mm mounting height. Confirm the equivalent figure for your specific KR1000 wafer from the product drawing, and check it against enclosure clearance — particularly in stacked board designs where a controller, a sensor board, and a power board are layered. Vacuum placement. The SH shrouded header has locking features for its mating housing but no holes in the shroud. Holes give pick-and-place nozzle vacuum somewhere to leak, which forces a special nozzle or a taped part. With no holes, the header places with the same nozzle as the rest of the SMT line. The KR1000 shrouded header is documented the same way. If you are quoting an automated assembly, confirm this explicitly — it is a real cost item. Operator handling. The JST SH housing carries protrusions at both ends so an assembly operator can unplug it without gripping the wires. Pulling 1.0mm pitch wires is the single most common cause of terminal damage in this class. The KR1000 is documented with the same feature, and is offered in housing versions with and without the ear if your tooling or panel access requires the narrower body. Wire-side process. Termination is by crimping, on AWG #28 to #32 wire. At this scale, crimp consistency is the dominant failure mode — the strip length (around 1.0–1.2mm), the conductor and insulation wing positions, and the die setting all have to hold. For volume production, buying pre-crimped assemblies moves that variability into a factory process with pull-test data instead of a bench operation. KONNRA supplies both.

Circuit Count Range and PCB Layout Considerations

The KR1000 covers 2 through 20 circuits in a single row and 2×4 through 2×30 in dual row. The table below gives the single-row contact-field width for common configurations, calculated from the 1.0mm pitch.

Circuits (single row) Pin-field width (calculated from 1.0mm pitch)
2 1.0mm
3 2.0mm
4 3.0mm
5 4.0mm
6 5.0mm
7 6.0mm
8 7.0mm
10 9.0mm
12 11.0mm
15 14.0mm
16 15.0mm
20 19.0mm

How to read this table. Width = (N − 1) × 1.0mm, where N is the circuit count. This is the distance across the contact field only — not the overall housing or wafer outline, which adds shrouding and solder tab geometry on top. Overall dimensions, the SMT pad pattern, solder tab positions, and stencil recommendations must come from the KR1000 drawings linked above, or be requested for your specific circuit count and orientation. Board design notes:

  • Confirm straight 180° or right-angle 90° before quoting — the two need different pad geometry and different enclosure clearance.
  • Check the dual-row footprint if you are moving from multiple single-row connectors. Dual row changes both the pad pattern and the board area consumed.
  • Verify mated height against your enclosure, including the wire bend radius behind the housing.
  • Tie the accepted wire insulation diameter (0.4–0.8mm) to the connector drawing rather than to the cable supplier's nominal figure.
  • Specify plating explicitly if you need gold rather than the standard tin finish.

JST SH 1.0 vs JST GH 1.25 vs JST PH 2.0 vs JST XH 2.5

These four JST families are constantly confused with each other because they share a design language. They are not interchangeable at any level, and the differences that matter most are not the pitch — they are current rating and mounting type.

Feature JST SH 1.0 JST GH 1.25 JST PH 2.0 JST XH 2.5
Pitch 1.0mm 1.25mm 2.0mm 2.5mm
Current rating 1A 1A 2A 3A
Voltage rating 50V AC/DC 50V AC/DC 100V AC/DC 250V AC/DC
Mounting SMD only SMD only Through-hole and SMD Through-hole
Typical wire AWG #32–#28 AWG #30–#26 AWG #32–#24 AWG #28–#22
Typical use Micro FPV, wearables, compact IoT Pixhawk / ArduPilot standard, compact IoT LiPo batteries, Arduino-class sensors 3D printers, RC balance leads, power wiring
KONNRA equivalent KR1000 KR1259 KR2004 / KR2001 KR2501

How to choose. Start from the current you need and the space you have, not from the pitch:

  • 1A or less, and board height is the constraint → SH 1.0 / KR1000
  • 1A or less, and you need the Pixhawk ecosystem standard → GH 1.25 / KR1259
  • Up to 2A, through-hole acceptable, common in hobby and battery wiring → PH 2.0 / KR2004
  • Up to 3A, larger mechanical retention needed → XH 2.5 / KR2501

A note on conversion. Because these families look alike, substitution errors are common and expensive — a 1.0mm housing will not mate with a 1.25mm header, and neither will fit the other's pad pattern. The only reliable method is to cross-reference on the specific part number, which is what the cross-reference check below is for.

Sourcing the JST SH 1.0: What Procurement Teams Ask

Engineering decides that a connector will work. Procurement decides whether the supply chain around it is safe. These are the questions that come up in nearly every qualification, with the straight answer for each. "Can you be a second source without changing our design?" That is what a documented cross-reference is for. The KR1000 is specified against the JST SH at the component level — housing, header, and terminal — with matching pitch, voltage, insulation range, and withstanding voltage. We will confirm equivalence against your specific part number rather than a generic series claim, because circuit count and entry direction change the answer. "What are your lead times?" Connector production lead time is typically 2–3 weeks. Wiring harness lead time is typically 3–4 weeks. Key materials are prestocked to shorten cycles. "How long for samples?" Complete connector set samples can be delivered within 45 days. Where you need to validate crimp quality or a cable assembly before committing, sample harnesses can be supplied from the same process used in production. "What qualifications do you hold?" ISO9001, ISO14001, IATF16949, ISO45001:2018, ISO13485, IPC620, and UL product and operational safety certifications. Automotive-grade series additionally hold LV214 and US CAR-2. These are the certificates procurement typically needs to open a supplier record. "How do we know the parts actually match your documentation?" A CNAS-accredited laboratory with 45+ sets of precision testing instruments, plus dimensional and electrical verification data available on request. 95% of production processes carry full-line intelligent visual CCD inspection; automotive series receive 100% CCD inspection. "Are you a trading company or a manufacturer?" A manufacturer. Dongguan Konnra Electronics Co., Ltd. was founded in 2004 and runs its own mould design, injection moulding, stamping, assembly, and inspection. Four production bases, 600+ employees, and in-house wiring harness assembly — which is why the connector and the cable assembly can come from the same quality system. "What volumes can you support?" KONNRA reported 2025 sales of RMB 310 million, with connectors at 60% and wiring harnesses at 40% of the product mix. Production runs across four factory bases, with automation coverage exceeding 95% across production lines. "Who else buys from you?" KONNRA has served global cooperative clients including BYD, Volkswagen, and DJI. **Request the vendor qualification pack** — certificates, test capability summary, product drawings, and a sample plan in one enquiry.

How to Get a Cross-Reference Check on Your Part Number

Most connector sourcing enquiries stall on the same thing: the buyer is not sure which information the supplier needs, so the enquiry never gets sent. Here is the complete list. If you have these, the cross-reference can be confirmed rather than estimated. Send us: 1. The original JST part number, if you have it — for example `SHR-06V-S-B`, `BM06B-SRSS-TB`, or `SSH-003T-P0.2-H` 2. Circuit count and row configuration (single or dual) 3. Entry direction — top entry / straight, or side entry / right-angle 4. Wire specification — AWG size and insulation outside diameter 5. Application and annual volume, so the configuration, tooling, and packaging can be matched to your programme 6. A drawing or photo, if the part number is unreadable or the design has been reverse-engineered 7. Any qualification requirements — automotive, medical, or specific test standards What you get back: a mapped KONNRA part number with the relevant product and engineering drawings, a specification comparison against your original part, and a sample and quote plan. If you are not sure what you are holding, send a photograph next to a ruler and we will identify the series from the pitch and the housing profile. **Send your part number or photo** · Email: info@konnra.com · Phone: (86)-769-85449875

Engineer's Pre-Release Checklist

Run this before you release a drawing for a 1.0mm pitch connector. Each line is a failure mode we see in practice.

  • Pitch confirmed by measurement or part number — not by appearance. 1.0mm and 1.25mm parts look similar and do not mate.
  • Circuit count within the family's range. If you need more than 20 signals at 1.0mm pitch, check the dual-row option before you split into multiple connectors.
  • SMD footprint, not through-hole. Both the SH and the KR1000 are surface-mount only.
  • Insulation diameter inside 0.4–0.8mm. Wall thickness varies between cable suppliers at the same AWG.
  • Gold plating stated explicitly if required — tin is the standard finish on the SH terminal.
  • Mated height checked against the enclosure, including wire bend radius.
  • Vacuum placement requirement confirmed with the assembly house — a hole-free shroud avoids a special nozzle.
  • Plating thickness and material called out on the drawing if the application is automotive or medical.

Send us your drawing. We will review it against the KR1000 specification and come back with any mismatch we find — before you commit tooling. **Submit a drawing for review**

Applications and Cable Assembly Options

Application Why the KR1000 fits

Frequently Asked Questions

What is a JST SH 1.0 connector?

The JST SH is a 1.0mm pitch, single-row, wire-to-board crimp connector with SMD mounting and a side latch. It is rated 1A AC/DC at 50V, accepts AWG #32 to #28 wire with insulation O.D. of 0.4–0.8mm, and is available in 2 to 16 and 20 circuits. It was the industry's first 1.0mm pitch crimp-style connector. The KONNRA KR1000 series is documented as its cross-reference equivalent, and adds a dual-row version from 2×4 to 2×30 circuits.

What is the KONNRA equivalent of the JST SH 1.0?

The KONNRA KR1000 series — a 1.0mm pitch SH wire-to-board connector available in single row (2–20 circuits) and dual row (2×4–2×30 circuits), rated 1A at 50V, with straight and right-angle SMT wafers, housings with or without the end ear, and a crimp terminal.

Does the JST SH come in a dual-row version?

No. The JST SH is a single-row series. If you need more than 20 signals at 1.0mm pitch, the KONNRA KR1000 dual row covers 2×4 to 2×30 circuits — 8 to 60 contacts — at the same pitch, which avoids splitting the design across multiple single-row connectors.

What is the difference between JST SH and JST GH?

Pitch and ecosystem. The SH is 1.0mm; the GH is 1.25mm. Both are SMD-only and rated 1A. The GH is the Pixhawk / ArduPilot standard for GPS, telemetry, and power ports; the SH dominates micro FPV builds, wearables, and compact IoT boards. They do not mate with each other. The KONNRA equivalents are KR1000 (SH) and KR1259 (GH).

What wire gauge does the JST SH 1.0 use?

JST specifies AWG #32 to #28 (0.032–0.081mm²) with an insulation outside diameter of 0.4–0.8mm. AWG #28 is the most common choice where current matters. Avoid wire thicker than AWG #28 — it will not crimp correctly into the SSH-003T terminal. The KONNRA KR1000 is documented with the same 0.4–0.8mm insulation range.

What is the insulation resistance of the JST SH?

100MΩ minimum, per JST's SH series documentation. Be aware that many third-party listings quote 1,000MΩ — a ten-fold error that appears to be copied from another series. The KONNRA KR1000 is documented at the same 100MΩ minimum. If your test specification was written from a third-party source, it is worth checking against the original datasheet.

What is the current and voltage rating of the JST SH 1.0?

1A AC/DC per contact, with 50V AC/DC rated voltage, specified with AWG #28 wire. The KONNRA KR1000 is documented at 1A and 50V. Note that the current rating is per contact — paralleling contacts in a power connection changes the practical capacity, but do not extrapolate beyond the published rating without engineering review.

Does the JST SH have a through-hole version?

No. The JST SH is an SMD-only series, and the KONNRA KR1000 is likewise offered only in SMT straight (180°) and right-angle (90°) configurations. For a through-hole alternative at a larger pitch, JST PH 2.0 (KONNRA KR2004) is the usual route.

What is the mounting height of the JST SH?

JST documents the side-entry SH at approximately 2.95mm mounting height. Confirm the equivalent figure for your specific wafer part number against the product drawing, and check it against enclosure clearance and wire bend radius.

Why does the header shroud have no holes?

So that vacuum from a pick-and-place nozzle cannot leak. A hole-free shroud means the header can be placed with the same nozzle as the rest of the SMT line, instead of requiring a special nozzle or a taped part. Both the JST SH and the KONNRA KR1000 headers are documented this way.

Can the JST SH header be used with IDC termination?

Yes — JST documents the SH shrouded header as compatible with SR series IDC sockets, so the same PCB footprint can be terminated by crimping (SH) or by insulation displacement (SR). Confirm against your specific header part number before designing around it.

How do I know which JST connector I actually have?

Measure the pitch — the centre-to-centre distance between adjacent contacts. 1.0mm indicates SH, 1.25mm indicates GH, 2.0mm indicates PH, and 2.5mm indicates XH. Housing width is a fast cross-check: a 4-circuit SH housing is about 5.0mm wide, while a 4-circuit GH housing is about 6.25mm. If you are still unsure, photograph the connector next to a ruler and send it to us.

How long does it take to get samples?

KONNRA can deliver complete connector set samples within 45 days. Connector production lead time is typically 2–3 weeks and wiring harness lead time typically 3–4 weeks.

Sources and method. JST SH 1.0 specifications and part numbers are taken from JST's published SH series product documentation — pitch, circuit counts and housing/header part numbers, current and voltage ratings (1A AC/DC with AWG #28; 50V AC/DC), temperature range (−25°C to +85°C), contact resistance (30mΩ max initial, 50mΩ max after environmental tests), insulation resistance (100MΩ min.), withstanding voltage (500V AC for one minute), conductor size (AWG #32–#28), insulation O.D. (0.4–0.8mm), housing material (PBT natural; header base housing PA heat-resistant), terminal part number and finish (SSH-003T-P0.2-H, copper alloy, tin-plated), mounting height, entry types, and SR-series IDC socket compatibility. KONNRA KR1000 specifications are taken from KONNRA's published single-row and dual-row product documentation. Where the two sources disagree, or where a widely-circulated third-party figure differs from the manufacturer's, the difference is called out in this guide. Always confirm final dimensional and electrical requirements against the current manufacturer drawing for your specific part number.
