Product details

Three-piece kit: header, housing, terminal

The B03B-XASK-1 is the board-mounted half of a JST XA series wire-to-board connection. It mates with the XA receptacle housing and the appropriate crimp terminal to complete the harness.

Termination and mounting options

The header accepts both press-fit and solder termination, giving the board assembler flexibility: press-fit for a solderless backplane process, solder for conventional wave or hand assembly.

RoHS status and the LF sibling

This variant is RoHS non-compliant. For RoHS-required builds, the LF-suffix peer B03B-XASK-1(LF)(SN) is the direct functional equivalent with the same pitch, current, and locking ramp.

Frequently asked questions

What is the mating connector for B03B-XASK-1?

The B03B-XASK-1 mates with a JST XA series receptacle housing (e.g., XARP-03V or similar) and the corresponding crimp terminal (e.g., SXA-001T-P0.6). The three-piece system – header, housing, terminal – must all be from the XA series to ensure proper fit and locking.

Is B03B-XASK-1 RoHS compliant?

No, the B03B-XASK-1 is RoHS non-compliant. If your BOM requires RoHS, order the LF-suffix variant B03B-XASK-1(LF)(SN) instead – it is the same part with RoHS-compliant plating.
