Tin Mating Finish vs Gold – When It Matters
This part uses 100 µin tin on the mating surface. Tin is a durable, low-cost contact finish, but it forms an oxide layer that requires a wiping action during mating to establish a low-resistance connection. For a connector that mates once or twice in its life — typical for a board-to-board jumper or a programming header — tin is perfectly adequate.
It is RoHS compliant and available in bulk packaging. Sourced through independent distribution channels.
