Board-to-board fit: 76 positions, 2.54 mm pitch
The 76342-338LF is the 76-circuit member of Amphenol ICC (FCI)'s Dubox board-to-board receptacle line, a through-hole part with a mated stack height of 11.04 mm.
What the pitch and plating mean for the build
The push-pull fastening and blue UL94 V-0 thermoplastic housing give a positive tactile mate without a locking latch; the glass-filled material holds up to reflow and field rework.
