The Amphenol FCI 68697-458HLF is a 58-position, dual-row male pin header from the BERGSTIK II series. It is an unshrouded, board-to-board header with a 0.100" (2.54 mm) pitch on both rows and between rows, making it a standard footprint for prototyping and production builds that need a dense but widely compatible interconnect. The right-angle through-hole termination orients the pin field parallel to the PCB, which suits board-edge or mezzanine-style connections where the cable or mating board exits parallel to the main board. Rated 5 A per circuit with tin-plated contacts on both the mating and post sides, this header is a workhorse for signal and moderate power distribution in equipment where repeated mating cycles are not the primary concern.
Key specifications and what they mean for your build
The 58 positions are fully loaded across two rows, so the BOM line for a 58-circuit board-to-board connection matches exactly — no unused positions to account for. The 0.100" pitch is the de facto standard for 0.025" square pin headers, which means the footprint is well understood by PCB layout tools and the mating receptacle is widely available across multiple manufacturers. The 5 A per circuit rating is typical for a tin-plated square pin at this pitch; the limiting factor is the temperature rise of the housing at full load across all 58 circuits, so derating is advised if the ambient exceeds the standard operating range. The right-angle orientation places the pin tips 0.230" (5.84 mm) from the housing face, which sets the mating depth for the receptacle. The 0.125" (3.18 mm) solder post length is sized for standard 1.6 mm PCBs — confirm it protrudes enough for your board thickness and wave solder process.
Construction and compliance
The housing is rated UL94 V-0, so it meets the flame retardancy requirement for equipment inside an enclosure. Contacts are phosphor bronze with 100.0 µ" (2.54 µm) tin plating on the mating surface and tin on the solder post — the thick plating provides good corrosion resistance for the contact zone in indoor, controlled environments. The push-pull friction fit (unshrouded) means there is no locking latch; the retention comes from the interference fit of the pins in the mating receptacle. For vibration-prone applications, a secondary locking mechanism or a shrouded header from the same series would be a better fit.
