The gold-on-gold mating interface avoids the tin-whisker risk that can arise with tin-on-tin contacts in high-vibration environments. ## Housing Material and Flammability Rating The insulator is a glass-filled thermoplastic rated UL94 V-0. That flame rating is required for connectors inside enclosed equipment — telecom switches, industrial controllers, and automotive ECUs all specify V-0 for the plastic components in the current path. The base product number is 71991; the -304LF suffix encodes the 8-position, dual-row, gold-plated variant. The same base covers other position counts and plating options in the Dubox™ family.","metaTitle":"71991-304LF Dubox™ 8-Pin Receptacle, 0.100\" Pitch, 2 Row","metaDescription":"71991-304LF Amphenol ICC (FCI) Dubox™ board-to-board receptacle, 8 positions, 2 rows, 0.100\" pitch, 30.0µin gold mating finish.
