Receptacle Housing for 2.50mm-Pitch Wire-to-Board Harness
The JST XARR-08VF is an 8-circuit receptacle housing from the XA series, designed for wire-to-board or wire-to-wire interconnect in harness assemblies. It accepts male pin crimp terminals (ordered separately) and mates with the corresponding XA series header. The 2.50mm pitch and single-row layout suit compact, medium-density harness routing in consumer electronics, industrial controls, and automotive interior applications. The housing is molded from natural polyamide (nylon) with a latch-lock fastening system that provides audible and tactile feedback on full mate, reducing the risk of partial connection in field-service or production-line assembly. Panel-mount capability allows the receptacle to be fixed to a chassis or enclosure panel, taking strain off the wire harness.
Key Specs at a Glance
8 positions in a single row at 2.50mm pitch — the circuit count and pitch must match the mating header exactly. Termination is crimp-style, requiring the correct male pin terminal to be crimped onto the wire before insertion. The latch lock holds the mated pair together under vibration — a practical detail for harnesses routed in moving equipment or vehicles. Panel-mount feature adds mechanical retention at the chassis entry point.
Contacts Not Included — Order Separately
This is a housing only — the crimp contacts are sold separately. The listing explicitly notes Contacts Not Included. You will need to source the correct male pin terminals for the XA series, rated for the wire gauge your harness requires. Confirm the terminal part number against your wire size before placing the full BOM order.
