Why the Gold Mating Finish Matters
That thickness is a flash-grade gold — enough for repeated mating in a controlled environment, but not a heavy-duty cycle count. In a board-to-board application where the header is mated once during assembly and rarely cycled again, it is a cost-appropriate choice.
It is ROHS3 compliant.
The closest peer in the AMPMODU family is the 1376779-2 — also a 10-position single-row header, but through-hole (not SMT) and rated 3 A at 250 VAC with a thicker 8.00 µinch gold mating finish. If your board assembly uses wave solder and you need higher current margin or a heavier gold layer, the 1376779-2 is the functional alternative — but the footprint and mounting process differ.
