The Amphenol FCI (FCI) 87901-136HLF is the 36-position member of the BERGSTIK II unshrouded header series — a dual-row 0.100-inch (2.54 mm) pitch board-to-board male pin header rated 5 A per circuit at 110 V, with 30.0 µin (0.76 µm) gold over phosphor bronze contacts and a 0.820-inch (20.83 mm) mating pin length in a through-hole push-pull configuration.
What the ratings mean for fit
At 36 positions across two rows, this is the largest dual-row member of the BERGSTIK II series at this pitch — matching the 2.54 mm grid means the footprint drops directly onto standard 0.100-inch pitch board layouts without routing workarounds. The 5 A per-circuit rating handles power distribution across the header without derating into the connector as the limiting factor — that ceiling sits with the board trace and via current capacity. The 0.100-inch (2.54 mm) insulation height matches the row spacing, giving a flush board-stack profile when mated to the matching receptacle. The 0.820-inch (20.83 mm) mating pin length provides substantial engagement depth for header-to-socket retention under vibration or thermal cycling — the push-pull fastening type describes the pin entry geometry, not an actuation mechanism. Gold plating at 30.0 µin (0.76 µm) is the mid-grade option in the series — durable enough for repeated matings in test-fixture or field-service scenarios where the UL94 V-0 housing material sets the thermal ceiling for sustained current.
Lifecycle and sourcing posture
The 87901-136HLF carries an Active product status with no stated successor order code on record. The BERGSTIK II series is a long-standing industrial standard in the board-to-board header class — sourcing continuity is governed by the series lineage rather than a single position count. No official cross-reference appears in the ledger for this specific 36-circuit variant, so confirm the mating half and position count against the BOM before committing.
