The Amphenol FCI 68657-403HLF is a 3-position unshrouded pin header from the BERGSTIK® II series, on a standard 0.100" (2.54 mm) pitch in a single row. It terminates through-hole with solder tails, making it a direct-fit choice for board-to-board signal or low-power interconnects where a shrouded housing isn't required. The tin-plated mating surface (100 µ" thick) and phosphor bronze contacts are rated for 5 A per circuit at 110 V, with a UL94 V-0 black insulation body.
What the ratings mean for the fit
The 0.100" pitch is the industry-standard grid for legacy and general-purpose PCB layouts — it routes easily on two-layer boards and leaves enough room for trace escape between pads. The 5 A per-circuit rating is typical for a tin-plated contact at this pitch; the limiting factor is the temperature rise of the unshrouded housing, not the contact itself. The 100 µ" tin plating on the mating surface is a heavy deposition that withstands repeated insertion cycles better than a flash coat, though it will not match the cycle life of a gold-plated contact in a corrosive environment.
Sourcing and lifecycle
The 68657-403HLF carries an Active lifecycle status from Amphenol FCI — no end-of-life notice on record.
