Board-to-Board Stack Height and Pitch
The 76341-312LF: The single-row layout keeps the board footprint narrow, and the 11.04 mm mated stack height sets the z-height budget for mezzanine spacing between two PCBs. The through-hole solder termination gives a reliable mechanical anchor for the connector body, especially in applications where the board sees vibration or repeated mating cycles.
30.0 µinch gold over nickel on the mating face — this is a standard thickness for moderate-to-high cycle life. In a field-service or industrial environment where the connector is mated and unmated quarterly, that gold layer resists fretting corrosion and keeps contact resistance stable over decades of service. The post tails are tin-plated (78.7 µinch), which is compatible with standard lead-free solder processes and provides a good wetting surface for the solder joint.
Housing Material and Flammability Rating
This is a standard requirement for connectors inside equipment enclosures that must meet safety agency approvals. The blue insulation color is a visual identifier for the Dubox series, helping technicians quickly identify the connector family during assembly or rework.
