The single-row, push-pull fastening style keeps the footprint simple — no shrouding wall to clear on the board, but also no polarization key to prevent a 180° mis-mate. ## Key Ratings & What They Mean The 0.100\" (2.54 mm) pitch and 0.318\" (8.08 mm) mating length are standard for the BERGSTIK® II family, so the mating receptacle (typically a 0.100\" pitch IDC socket or crimp housing) needs no special clearance. ## Construction & Termination Phosphor bronze square pins, through-hole solder tails 0.120\" (3.05 mm) long — the post length suits standard 0.062\" to 0.093\" PCB thickness with enough protrusion for a reliable solder fillet. The unshrouded design gives easy access for probing or manual wiring, but the board layout must provide the polarization; the header itself won't prevent a reversed mate. ## Cross-Reference Note The 93992-436HLF is a near-identical sibling in the same series: same 36 positions, same 0.100\" pitch, same tin plating and UL94 V-0 rating, but rated 3 A per contact instead of 5 A. If the BOM calls for 5 A headroom, the 78511-436HLF is the correct pick; the 93992-436HLF fits the same footprint and mates with the same receptacle but derates the current. No other functional cross-reference is on record.","metaTitle":"78511-436HLF BERGSTIK® II Header, 36 Pos, 0.100\" Pitch, 5 A","metaDescription":"78511-436HLF BERGSTIK® II unshrouded header, 36 positions, 0.100\" (2.54mm) pitch, tin-plated contacts rated 5 A.
