Product details

25-Position Single-Row Receptacle at 0.100" Pitch

The 66951-025LF is a 25-position, single-row board-to-board receptacle from the Dubox™ and BergCon® PV™ series by Amphenol ICC (FCI). Rated 1250V, the connector supports applications where voltage isolation is a concern — telecom line cards, industrial control panels, and medical equipment inside an enclosure.

30 µinch Gold Mating Surface for Field-Service Duty

The part is sourced multi-channel; stock availability varies, so an RFQ is the fastest path to a commitment.

Mates with BergStik Headers — Pinout Check Required

This receptacle is designed to mate with BergStik™ pin headers in the same 0.100" pitch, single-row configuration. Insulation height is 0.325" (8.25mm) — this sets the z-height budget when the mating header is on the opposite board. Confirm the stack height against your enclosure clearance before committing.
