2.50 mm Pitch, 2-Position Shrouded Header

Through-Hole Mounting with Press-Fit Option

Comparing 2-Position vs 7-Position XH Headers

Within the same XH series, the BH2B-XH-2(LF)(SN) (2 positions) and BH7B-XH-2 (7 positions) share identical pitch (2.50 mm), current rating (3 A), voltage (250 V), shrouding, and detent lock. The only difference is circuit count — choose the 2-position for a single wire pair, the 7-position for a multi-conductor harness. Both use the same crimp terminals and mating housings, so one family covers both jobs. The B2B-XH-AM(LF)(SN) is a 2-position XH header with a lower insulation height (9.8 mm vs 14.20 mm) and brass contacts instead of copper alloy. If board height is constrained, the B2B-XH-AM saves 4.4 mm of z-space but uses a different contact material — verify current derating if used near the 3 A limit.

Frequently asked questions

What is the closest functional second-source for BH2B-XH-2(LF)(SN)?

The BH2B-XH-2 (without the (LF)(SN) suffix) is the same header with identical pitch, positions, current, and voltage — functionally interchangeable. The (LF)(SN) suffix indicates RoHS compliance and tin plating; verify your assembly's RoHS requirement before substituting.

What crimp terminals mate with BH2B-XH-2(LF)(SN) for wire harness assembly?

This header mates with JST XH series crimp housings (e.g., XHP-2) and uses the SXH-001T-P0.6 or equivalent crimp terminal for 20-24 AWG wire.
