The FCI 79425-120HLF is a 20-position dual-row unshrouded male pin header from the BERGSTIK® II series. It uses the standard 0.100" (2.54 mm) pitch for both rows and between rows, making it footprint-compatible with a wide range of legacy board-to-board and wire-to-board applications. Rated at 5 A per contact with a 110 V voltage rating, it is suited for signal-level interconnects rather than power distribution. The mating finish is gold or Gold GXT™ at 30.0 µin (0.76 µm), a robust plating for repeated mating cycles in controlled environments.
Key Specifications and Fit
The header is unshrouded with a push-pull fastening type, meaning it relies on the friction of the mating receptacle for retention — no locking latch. The through-hole solder termination and 0.120" (3.05 mm) post length suit standard PCB thicknesses. The insulation height of 0.100" (2.54 mm) keeps the mated profile low. The UL94 V-0 flammability rating confirms the housing meets the flame-retardant requirement for equipment inside an enclosure. The 30.0 µin gold on the mating surface supports a moderate number of mating cycles — adequate for field-serviceable connections but not designed for high-cycle hot-swap duty.
