71-477102-98P

Overview

The Amphenol Aerospace Operations 71-477102-98P is a circular MIL-spec plug connector designed for rugged environments. It features a size 10 shell with a straight cable mount configuration and bayonet coupling. The unit contains six positions utilizing female socket contacts. Contacts are constructed from copper alloy with gold plating and terminate via crimping. The housing is made of aluminum alloy finished in olive drab cadmium.

Feature Summary

• Bayonet locking mechanism ensures secure mating in high-vibration conditions
• Crimp termination style supports reliable wire attachment
• Gold-plated copper alloy contacts provide corrosion resistance

Applications

• Military avionics systems
• Ruggedized ground vehicle electronics
• Naval ship interconnects

Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm contact arrangement and shell finish. Ensure compatibility with corresponding receptacles before procurement. Confirm environmental sealing requirements match the application needs. Check for any updated RoHS or REACH compliance statements in the latest documentation.

Selection Notes

Select this component when a size 10 circular plug with six female contacts is required. The straight cable mount design suits applications where space allows linear exit. Verify that the mating environment accommodates the bayonet coupling style. Ensure the crimp tooling matches the specified contact size for proper termination.

Part Context

This part belongs to the MIL-DTL-26482 series, which defines lightweight circular connectors for military use. The series emphasizes reduced weight compared to older MIL-C-26482 models while maintaining similar performance characteristics. Amphenol manufactures these connectors to meet strict defense industry standards for durability and electrical continuity.

Replacement Considerations

Cross-reference with MS3106 series equivalents for pinout compatibility. Verify that substitute parts maintain the same shell size and contact arrangement. Ensure the replacement meets the same MIL-DTL-26482 specifications for environmental sealing and mechanical retention.
