Product details

28-Position Single-Row Receptacle for Board-to-Board Stacking

The 66951-028: This is a 28-position, single-row receptacle from the Dubox™ and BergCon® PV™ series, designed for board-to-board applications. Rated at 1250 V, this part carries a voltage ceiling well above typical signal-level requirements, suiting it for isolation barriers or higher-potential applications within the board stack.

The push-pull fastening type allows tool-less mating and unmating — typical for Dubox receptacles mated with BergCon PV headers.

Frequently asked questions

It is a board-to-board receptacle from the Dubox / BergCon PV series.

Is 66951-028 compatible with 2.54mm pitch headers?
