The 0.100\" (2.54mm) pitch and 0.100\" row spacing define a standard footprint that mates with matching receptacles or IDC sockets. Rated 5 A per contact at 110 V, with a UL94 V-0 rated black housing. The tin-plated mating finish at 100.0 µin thickness provides a corrosion-resistant surface suited for applications with limited mating cycles. ## What the ratings mean for fit The 0.100\" pitch and 0.100\" row spacing are the industry-standard grid for many BergStik-compatible receptacles — the footprint is well-established, so board layout risk is low. The 5 A per contact rating is typical for signal-level interconnects; the limiting factor is the tin plating, not the contact cross-section. Tin contacts are rated for fewer mating cycles than gold — plan this header for one-time assembly or infrequent rework, not repeated field service. ## Mating and termination This is an unshrouded header with a push-pull fastening type. It mates with any standard 0.100\" pitch dual-row receptacle or IDC socket that accepts 0.025\" square pins. The through-hole solder termination has a post length of 0.120\" (3.05mm) and an overall contact length of 0.410\" (10.41mm). All 24 positions are loaded.","metaTitle":"79425-424HLF BERGSTIK II Header, 24 Pos, 0.100\" Pitch, 5A","metaDescription":"Amphenol 79425-424HLF BERGSTIK® II unshrouded header, 24 positions, 0.100\" pitch, 5A, tin plating, UL94 V-0.
