It uses a standard 0.100" (2.54mm) pitch on both the mating and row spacing, making it a drop-in fit for legacy 2.54mm grid layouts. The through-hole termination with a 0.120" (3.05mm) post length suits standard PCB thicknesses, and the 0.720" (18.29mm) mating pin length provides a generous engagement depth for the matching receptacle.
Mating and footprint
This header mates with any standard 2x20 pin socket or receptacle that uses a 0.100" (2.54mm) pitch and accepts a 0.720" (18.29mm) pin length. The dual-row layout with 0.100" (2.54mm) row spacing means the PCB footprint requires a 40-pin, 2-row pattern with 0.100" pitch in both axes. The 0.120" (3.05mm) solder tail length is typical for 1.6mm thick boards; for thicker boards, verify the post protrusion through the hole.
