Contact finish and mating cycle expectations
The 2307700-5: Both the mating and post contacts are tin-plated — 118.1 µin (3.00 µm) on the mating face, 12.0 µin (0.30 µm) on the solder tail. Tin is a cost-effective finish for moderate mating cycles (typically 50–100 cycles) in controlled environments; it does not offer the corrosion resistance of gold, so avoid repeated unmating in high-humidity or industrial fume exposure without a conformal-coated board.
