The 826936-6: The 6-position single-row layout keeps the board-edge routing tight — each pin occupies 2.54mm of linear space, so the total header footprint is just 15.24mm wide plus the solder pad keep-out.
Tin plating and mating cycle duty
Tin is a work-hardening finish — it's rated for a few dozen mating cycles in clean, dry environments. For a connector that gets mated once at board assembly and stays put, that's plenty. The 78.7µin thickness gives a consistent contact resistance without the cost of gold.
Typical mating halves are AMPMODU Mod II receptacles or industry-standard IDC sockets.
