Procurement Notes

Verify the specific suffix codes against official Amphenol documentation to confirm exact contact arrangements and shell finishes. Ensure compatibility with mating receptacles regarding thread type and engagement length. Cross-reference the manufacturer part number with authorized distributor catalogs to validate current production status and avoid obsolete stock. Confirm that the selected variant meets the required environmental sealing specifications for the intended installation.

Selection Notes

Select this connector based on its compliance with MIL-DTL-26482 Series I requirements for miniature cylindrical connectors. Evaluate the shell size and contact configuration against the wiring harness density and spatial constraints of the assembly. Consider the operating temperature range and environmental exposure levels to ensure long-term reliability. Verify that the crimp tooling and contact insertion tools are compatible with the specified contact types before procurement.

Part Context

This component belongs to the Tri-Start TV series or similar Amphenol circular connector families designed for aerospace and defense markets. These connectors are characterized by their compact form factor and high-density contact arrangements. The series supports both shielded and unshielded configurations depending on the specific model designation. They are widely used where weight reduction and simplified installation are critical design factors.

Replacement Considerations

Direct substitutes may include MS3126 series equivalents from other manufacturers adhering to the same MIL-DTL-26482 standard. Verify dimensional interchangeability, particularly regarding the coupling nut and shell diameter. Ensure that alternative sources provide identical contact plating and material specifications to maintain performance parity.
