The 0.100\" pitch and row spacing are the classic 2.54mm grid — any standard 0.100\" female socket strip or IDC receptacle will align. The overall contact length of 0.470\" breaks down to a 0.250\" mating section and a 0.120\" post length, which sets the board-to-board stack height and the through-hole depth on the PCB. ## Where it fits — board-to-board duty This is a board-to-board header, period — it sits on one PCB and mates with a female socket on another. Typical use is in card-edge or mezzanine stacking where the two boards are parallel and the header provides the signal path. The 38-pin count suits parallel data buses, I/O expansion headers, or general-purpose interconnect on a prototype or production board where the pinout is defined by the circuit count.","metaTitle":"FCI 86503-438HLF BERGSTIK II Header, 38 Pos, 0.100\" Pitch","metaDescription":"FCI BERGSTIK II unshrouded header, 38 positions, 0.100\" pitch, dual-row, through-hole, tin-plated, rated 5A at 110V.
