0.100" Pitch, 12 Positions, Dual-Row — What This Dubox™ Receptacle Does
The receptacle accepts a bottom or top entry pin header, and the push-pull fastening keeps the pair mated without additional hardware. Surface mount termination means the part reflows with the board; no through-hole soldering or secondary operations.
The gold-on-tin split is typical for a connector where the mating interface needs the cycle life and the termination side needs a solderable surface.
12 vs 4 vs 24 Positions — Picking the Right Circuit Count in the Dubox™ Line
The 89898-306LF sits at 12 positions in the Dubox™ dual-row SMT family. The closest sibling is the 4-position 89898-302LF, which shares the same pitch, stack height, and gold plating but carries fewer circuits — a straight circuit-count decision for the BOM. At the other end, the 24-position 89898-312LF doubles the circuit count in the same footprint width (same pitch, same row spacing). The choice between them is purely the number of signals or power lines the board-to-board link needs to carry. The box-packaged 89898-306LF is the manual or low-volume option.
