The FCI BERGSTIK® II 87900-158HLF is a 58-position, dual-row, unshrouded male pin header on a standard 0.100" (2.54mm) pitch — a direct footprint match for legacy 0.100" grid PCB layouts.
As an unshrouded header with push-pull fastening, the 87900-158HLF mates with any standard 0.100" pitch dual-row receptacle housing that accepts 0.025" square pins — no polarization or keying, so alignment is visual. The 0.720" (18.29mm) mating contact length provides good wipe for reliable contact. Board layout should account for the 0.100" (2.54mm) row spacing and the overall contact length of 0.940" (23.88mm) from the board surface to the tip of the pin.
