The Samtec 68405-172 is a 72-position, dual-row unshrouded male header from the BERGSTIK II series, designed for board-to-board interconnect applications on a standard 0.100-inch (2.54 mm) pitch with matching row spacing. This through-hole, right-angle configuration suits board-edge mounting where the connector runs parallel to the PCB, saving vertical space in the enclosure. The contacts are phosphor bronze with a gold or Gold GXT™ plating finish rated at 30.0 µin on the mating surface — sufficient for repeated mating cycles in moderate-duty signal or power distribution roles. Each circuit is rated for 5 A at 110 V, and the black UL94 V-0 housing meets flame-retardancy requirements for equipment inside enclosures.
Key ratings and what they mean for fit
The 72 positions at 0.100-inch pitch define the board footprint — a 36-column, dual-row layout that matches a wide range of standard IDC receptacles and female headers. The 5 A per-circuit rating is typical for this class of pin header and supports both signal and moderate power distribution; the limiting factor in practice is the total current across all pins and the temperature rise within the assembly. The 30.0 µin gold plating on the mating side provides a corrosion-resistant interface for environments where the connector may see multiple insertion cycles or extended field life. The right-angle orientation means the pins exit parallel to the board surface, which is useful for mezzanine or card-edge connections where a vertical header would not fit.
