68-circuit Dubox receptacle at 0.100" pitch
The 89883-434LF is the 68-circuit member of Amphenol FCI's Dubox board-to-board receptacle line, dual-row at 0.100" (2.54 mm) pitch with a matching row spacing of 0.100" (2.54 mm). Tin-plated phosphor bronze contacts (2.00 µm on both mating and termination sides) suit signal-level duty; the blue glass-filled thermoplastic housing carries a UL94 V-0 flammability rating.
Position count across the Dubox series
The 68-position 89883-434LF sits above the 50-position 89883-450LF and below the 80-position 89883-480LF in the same Dubox 0.100" pitch, dual-row receptacle family — the pitch, row spacing, contact plating, and housing material are shared across the series, so the position count alone drives the board footprint length.
