Contact system and board fit
The 89883-312LF is the 24-position dual-row member of the Amphenol ICC (FCI) Dubox board-to-board receptacle line, using a square female socket contact system with gold mating surfaces (30.0µin / 0.76µm) and tin post plating (78.7µin / 2.00µm). It mounts right-angle through-hole with solder termination, mates at 0.100" (2.54 mm) pitch with 0.100" (2.54 mm) row spacing, and carries a UL94 V-0 glass-filled thermoplastic housing in blue.
Mating and mounting notes
The push-pull fastening and 0.230" (5.85 mm) insulation height suit board-to-board stacking where the receptacle sits on the right-angle header side. The 0.114" (2.90 mm) post length determines the solder tail protrusion through the PCB.
