A board guide feature on the housing helps locate the header during assembly, which matters when the board is part of a multi-connector harness.","metaTitle":"JST XA Header B05B-XASK-1-A(LF)(SN) 5-Pos 2.5mm Tin","metaDescription":"JST XA series 5-position shrouded header, 2.50mm pitch, 3A, 250V, tin-plated contacts, locking ramp.

It is quoted to order against your BOM quantity — no stock-holding claim, availability confirmed at RFQ. Contact us with your target quantity and lead time requirement for a current price and delivery estimate."},{"question":"What is the pitch of B05B-XASK-1-A(LF)(SN)?","answer":"The mating pitch is 0.098\" (2.50 mm). This is the centre-to-centre spacing of the pins and sets the PCB footprint for the header."},{"question":"Are there alternatives to B05B-XASK-1-A(LF)(SN)?","answer":"The peer MPNs B05B-XASK-1-A and B05B-XASK-1 are functionally identical — same 5 positions, 2.50 mm pitch, tin plating, and locking ramp. The (LF)(SN) suffix indicates RoHS compliance and bulk packaging.
