It uses a standard 0.100" (2.54 mm) pitch in both rows and between rows, which matches the legacy 0.100" grid common on prototyping boards and many industrial PCB layouts. The tin-plated phosphor bronze pins are rated 5 A per contact, and the 100.0 µin (2.54 µm) tin mating finish is built for moderate mating cycles in a clean, indoor environment — think a control board inside an enclosure, not a field-service harness that gets cycled weekly.
The 0.100" pitch and 0.100" row spacing mean this header occupies a 0.100" x 0.100" grid — a 48-pin footprint that spans 23 holes across the board (0.100" x 23 = 2.300" total length) plus the two outer rows. The 0.380" (9.65 mm) mating pin length gives enough reach to engage a standard box receptacle or IDC socket, and the 0.120" (3.05 mm) solder tail is sized for a 0.062" nominal board thickness with room for a wave-solder fillet. Overall contact length is 0.600" (15.24 mm).
The 0.025" square pins accept standard 0.100" pitch IDC sockets, crimp-to-wire housings, or board-to-board receptacles with a 0.100" grid. Through-hole solder termination means it survives wave soldering and rework without the shear concerns of an SMT part.
The black insulation body and tin-plated pins give a clear visual contrast for post-solder inspection.
The base product number is 86837, so any variant search starts from that root.
