JST

JST is one of the most widely specified connector brands in consumer and industrial electronics, and the profiles here cover its two highest-volume wire-to-board families: the 2.5 mm pitch XH series — a 2-circuit top-entry header, a 5-circuit side-entry header and the matching crimp socket contact for 22 to 28 AWG wire — alongside the 2.0 mm pitch PH series 2-circuit top-entry header. These are the connectors behind countless power and signal harnesses. Confirm the exact ordering code including the (LF)(SN) lead-free tin-plated suffix, because pitch, circuit count and entry angle are not interchangeable across footprints.

Sourcing notes for JST parts. Always quote the complete manufacturer ordering code — package, temperature grade, speed or accuracy grade, and packing (reel, tube or tray) all change availability and price, and suffixes are where most mismatches happen. Check the lifecycle status on the manufacturer site before committing to a multi-year build; parts flagged not-recommended or obsolete need a last-time-buy plan or a verified alternate lined up early. With every offer, request traceability documents — date code, lot code and original packing — and confirm the inspection steps your supplier applies to high-risk lots.
