Board-to-Board Fit: 2.00mm Pitch, 8-Position Unshrouded Header
The 57102-F06-04U: The gold flash on the mating surface offers corrosion resistance for occasional mating but limits cycle life compared to thicker gold plating — expect a few dozen matings in a clean environment.
Lifecycle Status and Sourcing Reality
The 57102-F06-04U is marked Obsolete by Amphenol ICC (FCI). No official successor or pin-compatible replacement is listed in the Minitek 2.00mm series. For BOM lines that require this exact footprint, the only sourcing path is through independent distribution — quantities are confirmed at RFQ against available surplus or remaining stock.
What the Gold Flash Mating Finish Means for Reliability
The mating contacts carry a gold flash finish — a thin layer of gold over the copper alloy base. This provides initial corrosion protection and low contact resistance, but the flash thickness (typically under 10 µinch) wears through after repeated insertions. For applications requiring frequent board swaps or field rework, a header with thicker gold plating (15 µinch or more) would be a more durable choice.
