What this connector is
The Amphenol FCI 95687-464HLF is a 64-position dual-row board-to-board header in the BERGSTIK II series, 0.100 inch (2.54 mm) pitch, with through-hole solder termination and an unshrouded square-pin contact array. All 64 positions are loaded. The housing is black polyester rated UL94 V-0, and the push-pull fastening type refers to the pin-socket retention geometry rather than a latching mechanism — this is a friction-fit pin-header, not a locked connector pair.
Contact plating and what it means for the application
Contacts are tin-plated on both the mating face and the solder tail, with 100.0 µin (2.54 µm) on the mating surface. That heavy tin flash is the spec to watch — it sets the friction coefficient at first mate and limits reconnection cycle life compared to gold. This is a permanent-install header: tin-on-tin is built for a small number of mate cycles, not for field-removable service. The phosphor bronze base gives the beam compliance needed to maintain contact normal force through the life of the joint.
Ratings and what drives the selection decision
At 5 A per contact and 110 V, this sits at the upper end of the 2.54 mm pitch signal/power envelope. The 0.100 inch row spacing and 0.100 inch pitch define a 2-row footprint — confirm the board pad array matches before committing. The 0.360 inch post length clears typical boards for wave or hand-solder rework. The 0.100 inch insulation height defines the stacked board gap when this header is used as a stacking mate.
