2.00 mm pitch, 10-position unshrouded header
The post finish is tin, which solders cleanly into plated through-holes.
Board-to-board signal interconnect
The connector is classified as Board to Board style, meaning it is designed to mate with a receptacle on another PCB, not with a wire harness.
How it compares to 1376779-2
Both are 10-position, single-row, unshrouded, through-hole, with tin post finish. The key difference: 1376779-2 carries a 3 A current rating and 250VAC voltage rating, versus 2 A and 125VAC/DC here. The mating gold thickness on 1376779-2 is 8 µinch, compared to 30 µinch on this part. If your application needs higher current or voltage, 1376779-2 is worth evaluating — but the thinner gold may reduce mating cycle life.
