Product details

24-Position, 0.100" Pitch, Dual-Row Board-to-Board Receptacle

The 91618-312LF is a 24-position, dual-row board-to-board receptacle from the Amphenol ICC Dubox series. The connector is a bottom or top entry style with a push-pull fastening, and the board lock feature holds it in place during SMT reflow, resisting shear from cable strain in the final assembly. The mated stack height is 10.81mm, which defines the z-height budget for mezzanine board spacing — confirm this matches your board-to-board gap before layout.

Gold Mating Finish and Board Lock for Reliable SMT Assembly

The board lock feature provides mechanical retention during reflow and adds shear resistance once soldered, which is useful when the receptacle is mated to a header that sees cable strain.
