Peer comparison — gold thickness and plating options
The closest sibling is 3-178141-2, which shares the same 6-position, 2-row layout, 3.81 mm pitch, and board lock features, but carries 15 µinch gold on the mating surface instead of 30 µinch. If your application requires fewer mating cycles or a lower contact budget, the 15 µinch version is a cost-down alternative. Another variant, 3-178141-5, uses a tin mating finish (78.7 µinch) — suited for one-mate or low-cycle applications where gold is not needed.
