Board-to-board header for dense through-hole layouts
The Amphenol 86832-148HLF is a 48-position dual-row male pin header from the BERGSTIK II series, built on the standard 0.100" (2.54mm) pitch that matches legacy through-hole footprints. The UL94 V-0 black insulation and phosphor bronze contacts suit industrial control boards, test equipment, and telecom backplanes where the header is soldered into a plated through-hole and the mating half is a crimp-to-wire or IDC receptacle.
The 0.100" (2.54mm) pitch and 0.100" row spacing set a board footprint that has been a de facto standard for decades — the 48 positions fill a 24-pin-per-row layout, and the 0.100" (2.54mm) insulation height keeps the mated stack low enough for card-edge clearance inside a 1U chassis. The 0.325" (8.26mm) mating pin length gives the receptacle contact beam enough wipe to establish a stable interface; the 0.100" (2.54mm) solder tail length suits standard 0.062" (1.6mm) PCBs without protruding past the solder fillet. Tin-plated headers at the same pitch would be cheaper but would wear after a few dozen cycles in a corrosive or high-vibration environment. For a 48-position header that will be mated and unmated during test or rework, the gold finish justifies the BOM line.
For buyers filling a BOM line, the 48-position count and 0.100" pitch are the non-negotiable fit parameters.
