Product details

2.50 mm Pitch, 5-Position Shrouded Header for XA Series

The B05B-XASK-1-A(LF)(SN): Tin plating is a cost-effective choice for low-cycle signal applications — expect a few dozen matings before contact resistance starts to rise.

Through-Hole Press-Fit Termination and Mounting

Termination is press-fit, solder — the posts are inserted into plated through-holes and then soldered. 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.

Frequently asked questions

Where can I buy B05B-XASK-1-A(LF)(SN) and how is it quoted?

This JST XA header is sourced through independent distribution. 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.

What is the pitch of B05B-XASK-1-A(LF)(SN)?

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.

Are there alternatives to B05B-XASK-1-A(LF)(SN)?

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. Any of these can be used as a drop-in replacement.
