Rated 3A per contact at 250V, with tin-on-tin contact finish — a cost-effective signal interconnect for board-to-cable/wire applications.
The 0.118" (3.00mm) post length suits standard 1.6mm PCBs; the 11.3mm mated stack height leaves room for wire routing under the receptacle. Board guide on the header aligns the mating receptacle during assembly, reducing pin damage on blind-mate applications.
This header mates with JST XA series receptacle housings that accept crimp terminals. The locking ramp on the header engages with the corresponding latch on the receptacle — confirm the circuit count and pitch match your receptacle before ordering.
No — this part is listed as RoHS non-compliant. If you need RoHS compliance, the sibling B05B-XASK-1-A(LF)(SN) is functionally identical and RoHS compliant.
