71-477101-98P

Overview

The Amphenol Aerospace Operations 71-477101-98P is a circular MIL-spec connector plug designed for harsh environments. It complies with MIL-DTL-26482 Series I standards and features a bayonet coupling mechanism. The unit utilizes size 20 contacts and includes four discrete diodes integrated into the assembly. Constructed with an aluminum alloy shell finished in olive drab cadmium, it provides robust environmental sealing and mechanical durability for critical aerospace and military applications.

Feature Summary

• Integrates four discrete diodes within the connector assembly for signal conditioning
• Features a bayonet coupling system for rapid and secure mating
• Constructed from aluminum alloy with corrosion-resistant surface treatment

Applications

• Aircraft avionics systems
• Military communication equipment
• Radar instrumentation interfaces

Procurement Notes

Verify the specific datasheet revision to confirm diode specifications and contact plating requirements. Ensure compatibility with corresponding receptacle housing and tooling. Confirm that the olive drab cadmium finish meets project environmental compliance standards. Validate that the bayonet lock mechanism aligns with existing panel cutouts and mating constraints.

Selection Notes

Select this component when integrated diode functionality is required directly within the interconnect point. The size 20 contact configuration supports moderate current loads suitable for signal distribution. The MIL-DTL-26482 Series I designation ensures interchangeability with other manufacturers' compliant parts. Consider the physical dimensions of the plug body against available space constraints in the equipment rack.

Part Context

This part belongs to the 71 series of circular connectors manufactured by Amphenol Aerospace Operations. These connectors are engineered for high-reliability applications where vibration resistance and environmental sealing are paramount. The series offers various contact arrangements and shell sizes to accommodate diverse wiring needs across defense and commercial aerospace sectors.

Replacement Considerations

Cross-reference with other MIL-DTL-26482 Series I plugs featuring size 20 contacts and identical diode configurations. Verify that substitute parts maintain the same bayonet coupling style and shell material specifications to ensure mechanical fit.
