The Amphenol FCI 79425-158HLF is a 58-position, dual-row unshrouded male header from the BERGSTIK® II series. It sits on a standard 0.100" (2.54 mm) pitch with matching 0.100" row spacing, making it a direct footprint match for prototyping boards, IDC ribbon cable receptacles, and standard 2.54 mm grid layouts. All 58 positions are loaded, so the pin count matches the circuit count on the BOM without blanked or omitted positions.
Rated 5 A per contact at 110 V, the header handles signal-level and low-power duty — the current is well within the capacity of the phosphor bronze contacts with 30.0 µ" gold or GXT™ plating on the mating surface. That gold thickness (30.0 µin) supports repeated mating cycles without wear-through, suited for applications where the board may be disconnected and reconnected during test or field service. Through-hole solder termination with a 0.120" (3.05 mm) post length. The 0.100" insulation height and 0.410" overall contact length provide standoff for cleaning flux residue after wave soldering. The black UL94 V-0 rated housing is standard for equipment requiring a flammability rating inside an enclosure. Push-pull fastening means no latch or lock — the header relies on the friction of the mating receptacle's contacts for retention, which is typical for unshrouded headers in board-to-board or wire-to-board applications where the assembly is not subject to high vibration.
