Frequently asked questions
What is 66951-023LF's listed style and series?
The connector is listed as Style Board to Board in the Dubox, BergCon PV series.
What does the mixed plating on 66951-023LF mean for my application?
Gold at 30.0 µin (0.76 µm) on the mating interface gives durable, repeatable contact resistance across the lifecycle; tin at 100.0 µin (2.54 µm) on the solder tail provides robust solder wetting — this split is the series standard for signal-duty board-to-board applications.
