The Amphenol BERGSTIK 75844-318-34LF is a 34-position, dual-row unshrouded breakaway header on the standard 0.100" (2.54 mm) pitch. It's a through-hole solder-terminated male pin header with tin-plated phosphor bronze contacts rated for 5 A per circuit at 110 V. The breakaway construction means the 34-pin strip can be snapped to a shorter length if the BOM calls for fewer positions — though this variant ships fully loaded with all 34 positions. The unshrouded design leaves the pins exposed, so the mating receptacle must be aligned by the board layout rather than a keying shroud.
What the ratings mean for the board fit
The 0.100" pitch is the classic PC-board grid — it matches standard perf-board, legacy prototype boards, and many existing footprints. The 5 A per-contact rating is typical for signal-level interconnects; the tin plating (150.0 µin on the mating surface) is cost-effective for applications with limited mating cycles, but if the design calls for frequent disconnect-reconnect cycles, a gold-plated sibling in the BERGSTIK family would be the better call. The UL94 V-0 thermoplastic housing means the header is rated for equipment inside an enclosure requiring flame retardance.
Sourcing and lifecycle
The 75844-318-34LF carries an Active lifecycle status — full production, no end-of-life notice on record. There is no official successor or cross-reference on record, so confirm the BOM position count and the mating half before committing.
