The Amphenol FCI 75844-150-72LF is a 72-position dual-row breakaway header from the BERGSTIK series, on the standard 0.100" (2.54mm) pitch. The 5A per-contact rating at 110V is a signal-level current, not a power bus rating; the limiting factor at 72 positions is the contact density and the temperature rise across the full strip.
Footprint and layout fit
The 0.100" (2.54mm) pitch and 0.100" (2.54mm) row spacing place this header on the standard 0.1" grid — a 72-position dual-row layout occupies 36 pins per row across 3.6" of board edge. The 0.230" (5.84mm) mating pin length and 0.123" (3.12mm) solder post length are within the typical range for a through-hole solder joint on a 0.062" to 0.093" PCB.
The phosphor bronze contacts with 30.0µin GXT gold on the mating side are suited for corrosive or high-cycle environments where a tin-plated contact would wear or oxidise.
