Position Count and Gold Plating for Signal-Density Decisions
Compared to the 16-position 66953-008LF and the 12-position 66953-006LF, the 18-position 66953-009LF offers the highest circuit count in this dual-row, 2.54mm-pitch Dubox receptacle family, all sharing the same 30.0µin gold mating finish and 0.138" post length. The 10-position 66953-005LF is the smallest sibling; the 18-position variant is the practical maximum for a 2×9 layout on the same footprint.
