Procurement Notes

Verify the specific suffix codes against the manufacturer's current datasheet to confirm plating options and environmental sealing ratings. Ensure compatibility with corresponding receptacles regarding shell size and contact arrangement. Confirm that the crimp tooling matches the specified contact sizes for proper termination. Check for any updated compliance certifications required for your specific procurement jurisdiction.

Selection Notes

Select this model when a high-density circular interface is required within strict weight and space constraints typical of aerospace platforms. Consider the aluminum construction for general corrosion resistance and the gold plating for signal integrity. Evaluate the need for environmental sealing if operating in harsh conditions, as standard versions may require additional gaskets or seals depending on the specific application requirements.

Part Context

This component is part of the extensive MIL-DTL-38999 Series III portfolio offered by Amphenol Aerospace. These connectors are widely recognized for their reliability in military and commercial aerospace sectors. The series provides a standardized solution for interconnecting electronic components where vibration resistance and compact form factors are critical design parameters.

Replacement Considerations

Cross-reference with other manufacturers' MIL-DTL-38999 Series III equivalents such as those from LEMO or Glenair. Verify dimensional interchangeability and electrical specifications before substitution. Ensure that any alternative maintains the same shell size and contact configuration to fit existing panel cutouts and cable assemblies.
