What This Connector Is
The 75844-802-72LF is the 72-circuit member of Amphenol FCI's BERGSTIK® series — a dual-row breakaway header designed for board-to-board or cable interconnect at 0.100" (2.54mm) pitch. Square male pins in phosphor bronze accept either a matching BERGSTIK receptacle or a standard 0.100" pitch IDC ribbon cable assembly. The header ships fully loaded (all 72 positions populated) in bulk packaging. Rated 5 A per circuit at 110 V, with 15.0 µin (0.38 µm) gold GXT plating on the mating face and an operating range of -65°C to 130°C — the wide temperature ceiling makes it suitable for both board-stacking in instrumentation and cable-level interconnects in industrial enclosures where thermal cycling is a factor.
Ratings That Drive the Decision
The 5 A per circuit rating at 110 V covers most signal and moderate-power bus functions on a single connector — both the signal lines and the power rails can occupy the same 72-position header without derating to a lower-current alternative. Contact material is phosphor bronze, which provides good mechanical resilience at the spring interface. The gold GXT plating at 15.0 µin (0.38 µm) sits above the minimum gold thickness and delivers meaningful improvement in mating cycle life over tin-plated equivalents — it resists surface oxide in harsh environments and maintains lower contact resistance across repeated cycles. The UL94 V-0 thermoplastic housing satisfies flammability requirements in most industrial and commercial equipment enclosures.
