It uses square pins on the industry-standard 0.100" (2.54 mm) pitch, making it footprint-compatible with breadboard proto areas, standard 0.100" IDC sockets, and BergStik receptacles. The black UL94 V-0 rated housing stands 0.100" (2.54 mm) off the board, and the overall contact length of 1.225" (31.12 mm) gives a 0.900" (22.86 mm) mating tail — a long pin that reaches deep into a mating socket.
The 0.100" (2.54 mm) pitch is the classic DIP/breadboard spacing — if your board has a 0.100" grid, this header drops straight in. The 100 µ" tin plating is a heavy tin deposit — it survives occasional re-mates without galling, but if your application calls for hundreds of mating cycles, a gold-plated BergStik variant would be the right call. The 0.900" (22.86 mm) mating pin length means this header mates with standard BergStik receptacle housings and IDC sockets that expect a long pin for full contact wipe.
