The Amphenol 93690-102-10LF is a 10-position, dual-row unshrouded header from the BERGSTIK series, built on the standard 0.100" (2.54 mm) pitch that matches breadboard and legacy prototyping layouts. The housing is black UL94 V-0 thermoplastic, and termination is through-hole with a press-fit option for solderless backplane assembly.
The press-fit option is the one that stands out here — it lets you assemble without wave soldering, which is a real advantage in backplane builds where rework access is tight or where you want to avoid thermal stress on the board. The overall contact length is 0.685" (17.40 mm), with a mating length of 0.399" (10.13 mm) and a post length of 0.177" (4.50 mm).
Plating and Contact Design
The GXT alloy is harder than pure gold, so it resists wear through the wipe action of the square pin entering the receptacle contact. The tin on the post (39.4 µ") is standard for solder joints and won't cause issues as long as the board finish is compatible.
