XH2.54mm Wire-to-Board PCB Connectors – JST XH 2.54mm Compatible
XH2.54mm Wire-to-Board PCB Connectors – Compatible with JST XH 2.54mm Series
Yoeruyo's XH2.54mm connector range delivers reliable wire-to-board interconnection at the 2.54mm pitch, fully compatible with the JST XH series — a globally recognized wire-to-board connector system used across consumer electronics, industrial control, LED lighting, battery management, and development board applications. The XH2.54mm system combines a positive-latch housing, through-hole PCB headers, and precision gold-plated crimp terminals for secure, repeatable connections in space-constrained assemblies.

Buying Guide
- Circuit count – select the number of circuits to match your wiring requirements; available from 2 to 16 positions
- Wire gauge – XH2.54mm terminals accept AWG 28–22 (0.08–0.33mm²); confirm your wire gauge before ordering terminals
- PCB header orientation – vertical for standard wire-to-board connections; right-angle for edge-mount and space-constrained PCB layouts
- Pre-crimped assemblies – for OEM and production use, pre-crimped wire assemblies ensure consistent crimp quality and reduce assembly time
- Compatibility check – verify housing and header dimensions match JST XH 2.54mm series before ordering for drop-in replacement applications
Frequently Asked Questions
Is XH2.54mm compatible with JST XH series connectors?
Yes. Yoeruyo XH2.54mm housings and PCB headers are dimensionally compatible with JST XH 2.54mm series connectors. They mate correctly with genuine JST XH counterparts for drop-in replacement and system expansion.
What is the difference between XH2.54mm and standard 2.54mm KF/KK connectors?
XH2.54mm (JST XH compatible) and KF2510/KK254 (Molex KK compatible) both use the 2.54mm pitch but have different housing geometries and latch designs. They are not interchangeable — always match the housing to the PCB header series installed on your board.
What wire gauge is supported?
XH2.54mm crimp terminals accept wire from AWG 28 to AWG 22 (0.08mm² to 0.33mm²). AWG 26–24 is most common for signal and low-power wiring at this pitch.
Do you offer pre-crimped wire assemblies?
Yes. Custom wire-to-board assemblies with pre-crimped XH2.54mm terminals are available in specified wire lengths, gauges, and circuit counts. Contact us for OEM assembly quotations and lead times.
Do you offer bulk pricing for electronics manufacturers?
Yes. Yoeruyo offers tiered pricing for orders of 500 units or more. Contact us for volume quotations, mixed-SKU orders, and OEM packaging options for production line integration.
