Procurement Notes

Verify the specific contact type and orientation against the official datasheet before procurement. Confirm that the zinc nickel plating meets the required corrosion resistance standards for the intended operating environment. Ensure compatibility with mating connectors regarding shell size and interface dimensions.

Selection Notes

Select this model when a sealed, high-density circular connector is required for harsh environments. The zinc nickel finish provides superior corrosion protection compared to standard cadmium plating. Verify that the DB receptacle style aligns with the panel mounting requirements and cable entry needs of the design.

Part Context

This part belongs to the MIL-DTL-38999 Series III family, known for its compact size and high contact density. The Series III standard ensures interchangeability with other manufacturers' components meeting the same specifications. The zinc nickel finish enhances durability in corrosive conditions typical of aerospace and defense applications.

Replacement Considerations

Cross-reference with other MIL-DTL-38999 Series III suppliers for equivalent DB-style receptacles with zinc nickel finishes. Ensure that any substitute matches the shell size, contact count, and mounting style precisely.
