The Amphenol BERGSTIK 75844-101-20LF is a dual-row, 20-position male breakaway header on 0.100" (2.54 mm) pitch. It uses a push-pull, unshrouded design with through-hole solder termination and gold GXT plating (30 µin) on the mating contacts. Rated 5 A per circuit at 110 V, with a UL94 V-0 thermoplastic housing and an operating range of -65 to 130 °C, it is suited for board-to-board or cable interconnects where a standard grid footprint and moderate current density are needed.
The 0.100" pitch matches the legacy breadboard and prototype standard — the footprint is compatible with most 0.100"-grid perfboard and standard IDC receptacles.
Within the BERGSTIK family, the 20-position variant (75844-101-20LF) sits between the 10-position (75844-101-10LF) and the 30-position (75844-101-30LF) at the same 0.100" pitch and dual-row layout. The position count is the only decision variable — pitch, plating, current rating, and overall contact length (0.425") are identical across these three. Choose the position count that matches your circuit count; no other spec changes.
