What this connector is
The Amphenol FCI BERGSTIK II 93939-130HLF is a 30-position, dual-row board-to-board header with a 0.100 inch (2.54 mm) pitch, right-angle through-hole termination. Phosphor bronze contacts carry 5 A per circuit at 110 V, with gold or Gold GXT plating on the mating face at 30.0 µin (0.76 µm) and tin on the solder tails. The push-pull fastening and unshrouded profile make this a bare pin header suited for mating with the matching BERGSTIK II receptacle in card-edge or daughtercard applications.
What the ratings mean for your layout
The 5 A per contact rating is governed by the phosphor bronze base and the 30.0 µin (0.76 µm) gold-plated mating interface — the tin tails handle solder-side current transfer without limiting the circuit rating. For power-routing decisions, a 5 A dual-row 30-circuit header gives comfortable margin over typical logic-level backplane distributions and is well within the thermal ceiling set by the UL94 V-0 housing material.
Mating half and termination notes
This is an unshrouded male pin header — the mating half must be the matching Amphenol FCI BERGSTIK II dual-row receptacle with the corresponding 30-position, 0.100 inch row spacing. The square pin cross-section and push-pull fastening type indicate the receptacle locks by mechanical engagement rather than screw coupling; confirm the receptacle's polarity keying before specifying, as BERGSTIK II housings offer several keying options that affect blind-mate alignment in stacked board environments. Termination is through-hole solder with 0.120 inch (3.05 mm) post length and contact length at mating of 0.160 inch (4.06 mm). Verify the daughtercard thickness is compatible with the mating interface geometry before committing to the layout.
