Product details

Pitch, Pin Count, and Board Fit

The B40B-XADSS-N (LF)(SN): At 0.098" (2.50mm) pitch with 40 positions loaded all, this header occupies a 2x20 row layout. The row spacing matches the pitch at 0.098" (2.50mm) — the board footprint is a 40-pin dual-inline pattern with 0.138" (3.50mm) post length for through-hole soldering. The insulation height of 0.398" (10.11mm) gives clearance for the locking ramp and wire exit.

This header mates with JST XAD series receptacles (crimp-style socket housings) using the same 2.50mm pitch and locking ramp interface. The male pin contacts are circular, copper alloy with tin finish — designed for 3 A signal-level circuits.
