It uses the standard 0.100" (2.54mm) pitch on both the pin-to-pin and row spacing, which means it drops onto a 0.100" grid footprint — the same layout used by legacy 0.025" square-post headers going back decades. The male pins are phosphor bronze with a 100.0µin (2.54µm) tin finish on the mating surface and tin on the solder tails, rated for 5 A per contact at 110 V.
The 0.100" pitch is the defining dimension — it matches the industry-standard 0.025" square-post footprint, so any 0.100" pitch female socket or IDC connector with 0.025" square receptacles is a potential mate.
