Current rating and contact plating
The 9-102974-0-31: It carries 3 A per contact with gold-plated mating surfaces and tin-plated posts, suited for moderate-duty signal interconnects where repeated mating cycles matter.
At 31 positions on a single 0.100" (2.54mm) pitch row, this header fits board layouts needing a dense but unshrouded signal path. The breakaway design lets the installer snap the strip to the exact circuit count — the 31-position variant is a standard length in the Mod II range.
