The JST PHR-12 is a 12-position receptacle housing from the PH series, a 2.00 mm pitch wire-to-board connector family common in consumer electronics, appliances, and low-power industrial control wiring. The housing uses a detent lock for retention, which provides a positive tactile click when mated with the corresponding PH series pin header, but it is not a secondary-latch design; the lock holds under normal handling and moderate vibration but is not rated for high-shock environments.
Avoiding the Common Mistake: Contacts Are Not Included
The housing is a shell only — you must source the matching female socket contacts and crimp them onto your wire leads before insertion.
The 12-position count is the primary BOM match criterion.
Material and Temperature Range — Where It Can Live
That range covers indoor consumer gear, commercial lighting, and control cabinets, but it excludes automotive underhood or continuous outdoor exposure above 85°C. The natural (uncolored) nylon is the standard variant; no flame-rating or UV-stabilized version is listed for this part code, so it is intended for equipment inside an enclosure rather than open-air harness runs.
It is a standard catalog item from JST, widely distributed. No official cross-reference or second-source is available; the PH series is proprietary to JST.
