Board-to-Board Header, 15 Positions, 0.100" Pitch
The Amphenol ICC 91276-415HLF is a BergStik® II series unshrouded male pin header, 15 positions in a single row at the standard 0.100" (2.54 mm) pitch. It is a through-hole solder termination board-to-board interconnect — the square pins sit 0.900" (22.86 mm) long on the mating side and extend 0.225" (5.72 mm) through the board for soldering. The black UL94 V-0 rated insulation height is 0.100" (2.54 mm), matching the pitch for a compact inline footprint.
The 15-position count is less common than even-numbered BergStik headers (14 or 16 positions); confirm your BOM calls for exactly 15 circuits.
