Procurement Notes

Verify the specific contact arrangement and shell finish against the official TE Connectivity datasheet before procurement. Confirm that the PN contact configuration matches the system's power and signal requirements. Ensure compatibility with mating plugs and associated hardware. Check for any updated environmental compliance statements or alternate part numbers due to lifecycle changes.

Selection Notes

Select this part when a MIL-DTL-38999 Series III receptacle is required with integrated power and signal capabilities. Consider the size 21 shell dimensions for panel cutout specifications. Evaluate the operating temperature range and environmental sealing requirements against the application's exposure conditions. Verify mating connector compatibility to ensure proper alignment and engagement.

Part Context

This component is part of the extensive MIL-DTL-38999 connector portfolio from TE Connectivity, widely used in critical mission applications. The Series III designation indicates a high-density design optimized for weight and space savings compared to earlier generations. The 66601 prefix typically denotes a standard receptacle assembly configuration within this series.

Replacement Considerations

Check TE Connectivity documentation for direct cross-reference part numbers or updated revisions. Ensure any substitute maintains the same MIL-DTL-38999 Series III compliance, shell size, and contact arrangement to guarantee interchangeability without redesign.
