Dubox receptacle contact system
The 91615-422LF is the 44-circuit member of Amphenol ICC's Dubox™ board-to-board receptacle line, a dual-row surface-mount part accepting a bottom or top entry header. Mating contacts are tin-plated phosphor bronze with 78.7µin (2.00µm) thickness; the tin finish suits moderate-cycle applications where cost per position is the primary constraint.
Stack height and footprint
The 0.100" (2.54mm) pitch and 0.100" row spacing are shared across the Dubox series; the 44-position 91615-422LF mates to a 10.81mm stack height, which sets the board-to-board z-budget for the assembly.
