The mating surface carries a gold flash at 3.94 µinch (0.100 µm) over copper alloy — a light plating grade that resists oxidation through several dozen mating cycles.
It is ROHS3 compliant.
Comparing to Peer 1376779-2
The key difference: 1376779-2 is rated 3 A per contact (vs 2 A) and carries a thicker 8.00 µinch gold mating finish (vs 3.94 µinch), making it the better choice for higher-current or more frequent mating cycles.
