What this connector is
The Amphenol FCI 75844-318-06LF is the 6-circuit dual-row member of the BERGSTIK® breakaway header series — a through-hole male pin header rated 5 A per circuit at 110 V, with tin-plated phosphor bronze contacts and black UL94 V-0 thermoplastic housing. It is unshrouded and uses a push-pull fastening type, which means it mates with any standard 0.100-inch pitch dual-row receptacle or IDC housing sized for 6 positions. The dual-row layout at 0.100-inch row spacing gives a 2-position-by-3-position grid, making it a compact board-to-board or board-to-cable header in the most common 2.54 mm pitch family — pin-compatible with any 6-position dual-row 0.100-inch header from any supplier using the same footprint.
What the key ratings mean
The 5 A per-contact current rating is the per-circuit ceiling, not a summed bus rating. The 110 V voltage rating suits low-voltage industrial and instrumentation circuits. Tin contact finish at 150.0 µin (3.81 µm) provides multiple mating cycles before plating wear-through. Operating range is -65°C to 130°C, covering most industrial environments.
Physical fit for board layout
The insulation height of 0.100 inch (2.54 mm) is the mated stack height — when this header is mounted through a board and a receptacle is seated, the board-to-board spacing is nominally 0.100 inch per side, which is the defining dimension for the 0.100-inch pitch family. The overall contact length of 0.445 inch (11.30 mm), the post length of 0.120 inch (3.05 mm), and the mating contact length of 0.225 inch (5.72 mm) together tell the layout engineer what the total lead extension looks like through the PCB — critical when routing under or around the connector on a dense two-board stack. All 6 positions are loaded, so there is no open-position keying; pin-one orientation follows the standard diagonal chamfer or keyed-receptacle convention rather than any shroud on the header itself.
