Dubox 22-Pin SMT Receptacle for Mezzanine Stacking
The 91615-311LF is a 22-position, dual-row board-to-board receptacle from the Amphenol ICC Dubox series. The post finish is 78.7 µinch tin, which solders cleanly to the PCB pad.
Surface-mount termination with solder tails — the connector is designed for reflow soldering. The board lock feature provides mechanical retention during the solder process and adds shear strength to the joint. The insulation height is 0.275" (6.99 mm), which influences the clearance to adjacent components on the board.
Application Range and Compatibility
The connector type is a receptacle with bottom or top entry, meaning it can be used as a floating or fixed half in a board-to-board stack.
