How to Choose the Right Connector: Key Selection Criteria

Engineer connecting JST wire-to-wire connector cable assembly by hand — mating white JST SM or HY2.0 plug and socket housings on a PCB workbench with multi-color wiring harness

Mating a wire-to-wire connector cable assembly by hand: the plug housing (left) is aligned with the socket housing (right) and pushed together until the latch engages. Proper connector selection — matching pitch, current rating, and locking mechanism to the application — ensures reliable long-term connection.

Step 1 — Determine connection type: Wire-to-Board (WTB) connects a cable to a PCB header. Wire-to-Wire (WTW) connects two cable assemblies. See our Wire-to-Board Connector Types guide for a full framework.

Step 2 — Measure or determine the pitch: Pitch is the center-to-center distance between adjacent contacts. See How to Measure Connector Pitch if you are identifying an unknown connector.

Step 3 — Verify current and voltage requirements: Match the connector’s rated current to your application’s maximum continuous current. Apply a minimum 20% derating for continuous-duty applications.

Step 4 — Check wire gauge compatibility: Each connector series has a specified wire gauge range. See How to Crimp JST Connectors for crimping guidance applicable across most series.

Step 5 — Consider locking requirements: No-latch (DuPont, JST SH) for frequent disconnection; friction latch (JST PH, XH) for standard retention; belt-lock (XHS2.5) or retainer lock (Yeonho 25045HP-NNA) for vibration environments.

Step 6 — Consider contact material: Tin-plated contacts for standard applications; gold-plated for high-cycle or low-contact-resistance requirements. See Brass vs Phosphor Bronze Connector Contacts for material selection guidance.

Frequently Asked Questions

What connector cable brands does Keszoox supply?

Keszoox supplies pre-crimped connector cable assemblies compatible with four major connector families: JST (SH 1.0mm, GH 1.25mm, ZH 1.5mm, PH 2.0mm, PA 2.0mm, SAN 2.0mm, PHD 2.0mm, XH 2.5mm, XA 2.5mm, SCN 2.5mm, SM 2.5mm, EH 2.5mm, RCY 2.5mm, BHS 3.5mm, VH 3.96mm — 15 series), Molex (PicoBlade 1.25mm, 51005/51006 2.0mm, Mini-SPOX 2.5mm, KK 254 2.54mm, SL 2.54mm, Micro-Fit 3.0mm, Mini-Fit Jr. 4.2mm — 7 series), DuPont (2.54mm and 2.0mm), and Yeonho (HY2.0/SMH200 2.0mm, PHB2.0/SMAW200 2.0mm, XHS2.5/SMH250 WTB 2.5mm, SMH250 WTW/25045HP-NNA 2.5mm). All products use factory-crimped terminals and UL-rated wire.

What is the difference between JST and Molex connectors?

JST (Japan Solderless Terminal) and Molex are both major connector manufacturers, but their product lines serve different primary markets. JST connectors (SH, GH, PH, XH, VH) dominate the RC, drone, and maker electronics markets due to their compact pitch options and wide availability. Molex connectors (PicoBlade, KK 254, Mini-Fit Jr.) are more prevalent in industrial, automotive, and computer hardware applications. Both brands offer connectors at overlapping pitches (1.25mm, 2.5mm, 2.54mm) that are not cross-compatible despite similar dimensions.

What is the most common connector pitch for RC and maker electronics?

The most common connector pitches in RC and maker electronics are: 1.0mm (JST SH — flight controllers), 1.25mm (JST GH — Pixhawk; Molex PicoBlade), 2.0mm (JST PH — LiPo batteries; HY2.0 — RC/3D printers), and 2.5mm (JST XH — balance leads; XHS2.5 — industrial). The JST PH 2.0mm is the single most common connector in the 1S–3S LiPo battery ecosystem.

Are JST connectors and DuPont connectors interchangeable?

No. JST connectors and DuPont connectors are not interchangeable, even at the same pitch. The JST PH (2.0mm) and DuPont 2.0mm have different housing geometries, terminal designs, and mating interfaces. The DuPont 2.54mm and JST XH (2.5mm) are at different pitches and are not compatible. Always verify the exact series and pitch before ordering replacement connectors.

What wire gauge should I use with JST connectors?

Wire gauge depends on the connector series: JST SH and GH use AWG 28–32; JST ZH and PH use AWG 26–30; JST XH and VH use AWG 22–26. As a general rule, use the heaviest gauge within the connector’s specified range for power lines, and lighter gauges for signal lines. Keszoox pre-crimped assemblies use 22AWG for 2.5mm+ series and 26–28AWG for 1.0–1.5mm series.

What is the difference between wire-to-board and wire-to-wire connectors?

A wire-to-board (WTB) connector connects a cable assembly to a PCB-mounted header. A wire-to-wire (WTW) connector connects two cable assemblies directly to each other without a PCB. Most connector series offer both WTB and WTW variants (e.g., JST SM is WTW; JST XH is WTB). Some series are exclusively WTB (JST SH, GH) or WTW (JST PA, JST RCY). See our Wire-to-Board Connector Types guide for a complete framework.

Which Keszoox connector has the highest current rating?

The Molex Mini-Fit Jr. 4.2mm has the highest current rating in the Keszoox catalog at 13A per contact. The next highest is the JST VH 3.96mm at 10A per contact, followed by the Molex Micro-Fit 3.0 at 5A per contact. For applications requiring more than 13A, use a dedicated power connector outside the standard crimp connector families.

Summary

Keszoox supplies pre-crimped connector cable assemblies across 28 connector series from JST, Molex, DuPont, and Yeonho — covering pitches from 1.0mm to 4.2mm and current ratings from 1A to 13A per contact. All products use factory-crimped terminals, UL-rated wire, and are RoHS compliant.
