What this connector is
The Amphenol ICC 87185-422HLF is the 22-circuit, single-row member of the BERGSTIK II unshrouded header series, a classic 0.100-inch (2.54 mm) pitch board-to-board interconnect. Male pin contacts in phosphor bronze carry tin plating on both the mating interface and the solder tail — 100.0 µin (2.54 µm) on the mating side — and all 22 positions are fully loaded. The push-pull fastening type refers to the contact engagement geometry; this is not a latching or locking header, so it suits stationary board-stacking applications where the mated pair stays seated.
Ratings that drive the BOM decision
22 positions at 0.100-inch pitch sets the header footprint — confirm your board routing density and keep-out zone. The 5 A per contact rating at 110 V handles signal and low-level power distribution; current is per-contact, so your thermal budget determines how many circuits you load. The 0.100-inch insulation height sets the board-to-board stack separation.
Material and environment
Black insulation rated UL94 V-0 — the V-0 rating means this header is suitable for enclosed equipment where flame retardancy is required by the end-product standard. Phosphor bronze contacts provide spring compliance and conductivity for a tin-plated contact system.
