Product details

2.50 mm Pitch, 2-Position, 3 A — The Board-Fit Baseline

The B2B-XH-A(LF)(SN): Termination is through-hole press-fit with solder — the square pins (0.64 mm typical for XH series) insert into plated through-holes and are wave-soldered.

Tin-Plated Contacts and Temperature Range

Tin is rated for 50–100 mating cycles in clean, dry indoor environments — adequate for most consumer and industrial control applications. For corrosive atmospheres or frequent reconnection, gold-plated variants in the XH series are available. It does not extend to engine compartments or high-heat industrial zones without derating.

ROHS3 compliant.

Frequently asked questions

What is the closest functional second-source to B2B-XH-A(LF)(SN)?

The base part B2B-XH-A is electrically and mechanically identical — same pitch, current, voltage, and dimensions — differing only in the (LF)(SN) suffix. Both are active and interchangeable in the same footprint.
