Product details

Board footprint and routing fit

The S14B-XASK-1: This is a 14-position, single-row header on a 2.50mm pitch — the board footprint takes 35mm of edge real estate plus keep-out for the 4-wall shroud.

Rated power and mating duty

Operating temperature range is -25°C to 85°C, with a UL94 V-0 rated nylon 6/6 housing. That covers most indoor industrial and consumer equipment but not extended automotive underhood or outdoor direct-sun exposure.

Note: this part is marked RoHS non-compliant. If your build requires RoHS, the sibling S14B-XASK-1(LF)(SN) carries the same footprint and ratings with lead-free plating.

Frequently asked questions

What is the closest functional second-source for S14B-XASK-1?

The sibling S14B-XASK-1(LF)(SN) is the closest functional equivalent — same 14-position, 2.50mm pitch, right-angle, board-lock header, but with RoHS-compliant lead-free plating. It shares the same base product number S14B-XAS and mates with the same XA series receptacles.

Is S14B-XASK-1 RoHS compliant?

No, S14B-XASK-1 is marked RoHS non-compliant. If RoHS compliance is required, use the S14B-XASK-1(LF)(SN) variant.
