Position Count Variants in the 77313 Series

The same 77313-102 base part number is available in 14-position (77313-102-14LF) and 12-position (77313-101-12LF) variants, all sharing the same 0.100" pitch, dual-row layout, gold mating finish, and 3 A rating. The 20-position version offers the highest circuit count in this subgroup for applications requiring more I/O on the same footprint.
