If your assembly requires RoHS compliance, check the lead-free variant S03B-XASK-1(LF)(SN) — same form, fit, and function with RoHS-compliant plating. Mates with XA series crimp receptacle housings loaded with matching crimp terminals. Termination is press-fit and solder — the header is through-hole mounted, with the board lock providing additional retention during wave or hand soldering.","metaTitle":"JST S03B-XASK-1 Header 3POS 2.5mm R/A Board Lock","metaDescription":"JST XA series header, 3 circuits, 2.50mm pitch, right-angle through-hole, board lock, locking ramp.
