The Amphenol 79425-114HLF is a 14-position, dual-row unshrouded header from the BERGSTIK® II series. It uses the standard 0.100" (2.54 mm) pitch and row spacing, making it a drop-in fit for legacy through-hole layouts. Rated 5 A per contact at 110 V, with 30.0 µin gold plating on the mating surface, this header is suited for board-to-board signal interconnect where moderate current and repeated mating cycles are expected. The UL94 V-0 rated black insulation and phosphor bronze contacts round out the construction.
Key Specs and What They Mean for Your Build
The 0.100" pitch is the classic PC-board spacing — any board designed for a 2.54 mm header accepts this part without a layout change. The 14 positions (all loaded) match a 14-circuit BOM line; if your circuit count is different, look at the 10- or 20-position siblings in the same series. The 30.0 µin gold on the mating surface is a robust plating grade — it handles hundreds of mating cycles and resists corrosion in industrial or lightly corrosive environments better than a thinner flash. The 5 A per-contact rating is typical for this pitch class; it handles moderate power or signal duty without derating at room temperature, but if your ambient runs above 85 °C, plan on a derating curve check.
Mating and Termination
This is an unshrouded header — the pins are exposed. The mating receptacle must provide its own shroud, or the assembly needs a separate housing to protect the pins. The through-hole termination (0.120" post length) solders into standard 0.100" pitch plated-through holes. The push-pull fastening type means there is no locking latch; for vibration-prone environments, consider a shrouded header or a secondary retention method.
