Product details

What this 3-position XA header does for a board-to-wire link

The 2.50mm pitch and 3A per-contact rating make it a fit for low-to-medium current signal or power links, such as sensor inputs or actuator outputs.

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.

Frequently asked questions

Is S03B-XASK-1 RoHS compliant?

No, this part is listed as RoHS non-compliant. If you need RoHS compliance, the lead-free variant S03B-XASK-1(LF)(SN) is the functional equivalent with compliant plating.

What is the mating connector for S03B-XASK-1?

It mates with XA series crimp receptacle housings, such as XARP-03V, loaded with the matching crimp terminals. The locking ramp on the header engages with the receptacle latch.

What is the current rating of JST S03B-XASK-1?

Derate current above 85°C per the series derating curve.
