Rated 5A per contact at 110V, the 30.0µin (0.76µm) gold or Gold GXT plating on the mating surface handles repeated mating cycles without corrosion — the limiting factor for signal duty is the contact finish, not the current rating.
The 4-position 86832-104HLF shares the same 0.100" pitch, dual-row layout, and gold/GXT plating as the 8-position 86832-108HLF. No footprint change beyond the pin count, so a board laid out for one scales to the other without a layout revision.
