The Amphenol 93690-106-20LF is a 20-position, dual-row BERGSTIK® breakaway header. The 0.100" (2.54mm) pitch on both the mating interface and the row spacing puts it on the standard 0.100" grid — your board footprint is a straightforward 2x10 pattern of 0.025" square pins. The GXT alloy is harder than pure gold, so it holds up through repeated mating cycles without the galling you'd see on a tin-to-tin interface. It's rated 5A per contact and 110V, which puts it squarely in signal-level and moderate power distribution duty, not bus-bar work.
Termination is listed as both Press-Fit and Solder. The press-fit option means the compliant pin tail can be pressed into a plated through-hole without wave soldering — useful if you're running a backplane assembly where rework matters. The solder tail is 0.142" (3.60mm) long, and the overall contact length is 0.508" (12.90mm). For vibration-prone environments, you'd want a secondary locking feature or a potted assembly.
