What the 79425-110HLF is
The Amphenol FCI 79425-110HLF is a dual-row unshrouded male pin header in the BERGSTIK II series, built for board-to-board interconnects at 0.100" (2.54mm) pitch. All 10 positions are loaded — it is a fully populated 2-row connector, not a partial-load variant. The push-pull fastening type means the header relies on friction to retain the mating socket; no locking latch is present, so verify the vibration environment before committing this to a high-shock application. Phosphor bronze contacts carry 5 A per circuit with gold plating at 30.0µin (0.76µm) thickness on the mating face, and the housing meets UL94 V-0 flammability. The 110 V rating is suited for signal-level board-to-board paths rather than power distribution.
What the ratings mean for fit
Pitch is 0.100" (2.54mm). The 5 A per-contact rating governs the current ceiling; the dual-row layout at 10 positions handles signal bundles without approaching thermal limits at rated current. The insulation height of 0.100" (2.54mm) sets the board-stack separation when mated. Contact shape is square.
