What crosses into the harness
The 31-position 9-146280-0-31 sits between the 30-position 9-146280-0-30 and the 32-position 9-146280-0-32 in the same AMPMODU Mod II series; all three share the 0.100" pitch, single-row layout, gold mating finish, and 3A rating, so the choice is driven by circuit count alone.
