9-Position Board-to-Wire Header for the Universal MATE-N-LOK Series
Tin is cost-effective for low-cycle, non-corrosive environments — this part is not specced for repeated mating or field-service in humid conditions where gold would be preferred.
The 350586-1 offers a wider 6.35mm pitch and 9 circuits versus 12, with tin instead of gold on the mating interface. The 1318699-3 also carries a UL94 V-0 rating versus the V-2 on this part — a meaningful difference for equipment requiring the higher flame class.
