It carries 58 male square pins in a through-hole package, with all positions loaded. This is a general-purpose board-to-board or wire-to-board interconnect for parallel PCB stacking or mating with IDC receptacles. The 0.100\" pitch and 0.100\" row spacing together define a 0.100\" x 0.100\" grid — the classic footprint for dual-row BergStik headers, directly compatible with matching IDC sockets and ribbon cable connectors.","metaTitle":"FCI 79821-458HLF BergStik II Header, 58 Pos, 0.100\" Pitch","metaDescription":"FCI 79821-458HLF BergStik II unshrouded header, 58 positions, 0.100\" pitch, 5 A, tin-plated.
