The tin-plated post (100.0µin) is standard for solderability.
Mating Half and Board Stacking
Because it's unshrouded, the mating receptacle needs to guide the alignment — typically a 2x1 or 2x2 socket housing from the same AMPMODU Mod II or compatible 0.100" pitch family. Push-pull fastening means no latch; retention depends on the receptacle's friction.
Peer Comparison: 1376779-2
The closest alternate in the same series is 1376779-2 — also a 2-position, 2.54mm pitch, through-hole, unshrouded header with gold mating finish. For applications with fewer mating cycles or a cleaner environment, the thinner gold alternate may be acceptable; for repeated field service, the thicker gold here is the better choice.
