The Amphenol FCI 75844-802-72LF is a 72-circuit dual-row breakaway header from the BERGSTIK series, built on the industry-standard 0.100" (2.54 mm) pitch grid. It uses unshrouded square male pins with a through-hole solder termination, making it a general-purpose interconnect for board-to-board or cable-to-board applications where the user snaps the header to the exact position count needed. The 5 A per circuit rating at 110 V, paired with 15.0 µin gold GXT plating on the mating surface, suits it for moderate-current signal and power distribution in controlled environments.
What the ratings mean for your fit
The 0.100" (2.54 mm) pitch is the de facto standard for prototyping and legacy board layouts — it matches breadboard grids, standard IDC ribbon cable headers, and many development boards. The 72 positions are fully loaded across two rows with a 0.100" (2.54 mm) row spacing, so the board footprint requires a 2×36 through-hole pattern. The 15.0 µin gold GXT plating on the mating side is the real differentiator here: it supports repeated mating cycles and resists corrosion better than tin, making this header a better fit for field-serviceable assemblies or environments with moderate humidity. The unshrouded, push-pull fastening means there is no polarization key or latch — the mating connector relies on friction fit, so it is best suited for applications where the connection is not subject to high vibration or where a secondary retention method (e.g., wire ties, board-mount clips) is used.
