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.","metaTitle":"JST B40B-XADSS-N (LF)(SN) Header 40 Position 2.50mm Pitch","metaDescription":"JST XAD series shrouded header, 40 circuits, 2.50mm pitch, 3A, tin-plated, locking ramp.
