The Amphenol BERGSTIK II 92417-442HLF is a 42-position, dual-row unshrouded header on the standard 0.100" (2.54mm) pitch. It is a board-to-board interconnect, terminated via through-hole solder, with a push-pull fastening style. The tin-plated phosphor bronze contacts are rated for 5 A per circuit at 110 V, and the black UL94 V-0 housing suits it for general-purpose PCB stacking and wire-to-board applications where a shrouded shell is not required.
The 0.100" (2.54mm) pitch and 0.100" (2.54mm) row spacing set the board footprint — a standard grid that matches legacy and current PCB layouts. The 5 A per-contact rating is typical for a tin-plated signal header; the limiting factor in practice is the temperature rise through the 42 densely packed contacts, so derate if ambient exceeds 25 °C. The 100.0 µinch (2.54 µm) tin plating on the mating surface is a thick layer that handles a moderate number of mating cycles in a clean environment — it is not specified for frequent field reconnection or corrosive atmospheres, where gold would be the choice.
