Board-to-Board Header for Dense Signal Routing
The Amphenol BERGSTIK® II 93939-446HLF is a 46-position, dual-row unshrouded header on the standard 0.100" (2.54mm) pitch — the same footprint as legacy DIP packages, so it drops into existing PCB layouts without a board respin. The right-angle through-hole termination routes the pin array parallel to the board surface, which suits board-edge mezzanine stacking or right-angle cable-to-board transitions where the connector sits flush against the enclosure wall. Tin-plated phosphor bronze contacts carry a 5A per-circuit rating at the stated pitch — this is a signal-level interconnect, not a power bus. The 100.0µin (2.54µm) tin mating finish handles moderate mating cycles in permanent or semi-permanent installations; for high-cycle or corrosive environments, a gold-plated sibling in the BERGSTIK II family would be the better call. The UL94 V-0 black housing meets the flame-rating requirement for equipment inside an enclosure without needing a secondary barrier.
Sourcing and Lifecycle
The 93939-446HLF carries an Active lifecycle status from Amphenol — full production, no end-of-life notice on record. No official cross-reference or direct replacement is documented, so the BOM line is tied to this exact order code.
