What this connector is
The Amphenol 87916-102HLF is the 2-circuit member of the BERGSTIK II series — a low-profile unshrouded board-to-board header rated 5 A per circuit at 0.100" (2.54 mm) pitch. Square male pins in phosphor bronze carry gold or Gold GXT plating at 30.0 µin (0.76 µm) thickness on the mating face, and the insulator is UL94 V-0 rated black housing material. Through-hole push-pull solder tails and a 0.830" (21.08 mm) mating length give it the reach for stacking or pass-through board interconnects in industrial and instrumentation applications.
What the key ratings mean for your layout
The 0.100" pitch matches the industry-standard 2.54 mm grid — drop-in compatible with standard 0.100" pitch receptacle housings and IDC headers across multiple manufacturers. At 2 positions this is the smallest member of the series; the single-row layout keeps the board footprint narrow for backpanel pass-through or stacking tasks where only a couple of circuits need to cross the board boundary. 5 A per circuit with 30 µin gold plating on the mating side signals a step above tin-grade durability — more reconnection cycles available before the contact surface degrades. The 110 V rating keeps this in low-voltage signal territory rather than power-delivery range, so size the circuit accordingly.
Sourcing and BOM fit
Listed Active with no official successor or cross-reference. Confirm the BOM line matches 2 positions at 0.100" pitch with through-hole mounting before committing — the 0.830" mating length means the receptacle must have sufficient depth to accept the full pin engagement.
