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.","metaTitle":"JST B03B-XASK-1 Header – 3-Pos, 2.5 mm, Locking Ramp","metaDescription":"JST XA series header, 3 circuits, 2.50 mm pitch, shrouded 4-wall, locking ramp.
