Tin-on-tin vs gold-plated peers
The 8-215079-8 uses tin-on-tin contacts, while peer 1376775-2 uses gold-on-tin (8µin gold mating, tin post). Gold plating supports more mating cycles and resists corrosion better in harsh environments; tin is cost-effective for one-time or infrequent mate applications. If your BOM requires fewer circuits or SMT assembly, that part is a direct alternative within the same series.
