71-433031-98E

Overview

The 71-433031-98E is a circular MIL-spec connector manufactured by Amphenol Aerospace Operations. It belongs to the 38999 series and complies with MIL-DTL-38999 standards. The component is designed as a plug with a straight cable mount installation style. It features an aluminum shell with cadmium plating for environmental protection. The connector utilizes a bayonet coupling mechanism for secure attachment. Contact arrangements are defined by the insertion code 8-98, supporting specific pin configurations within shell size 8.

Feature Summary

• Bayonet coupling system ensures rapid connection and secure locking
• Cable mount design facilitates direct wire termination
• Aluminum alloy housing provides structural durability

Applications

• Aviation avionics systems
• Military ground equipment interconnects
• Radar signal transmission networks

Procurement Notes

Verify the exact contact arrangement against the official datasheet before procurement. Confirm that the cadmium-plated aluminum shell meets project environmental requirements. Ensure compatibility with mating receptacles sharing the same MIL-DTL-38999 designation. Check for any specific agency certifications required for defense applications.

Selection Notes

Select this model when a shielded circular connector with bayonet coupling is required. The straight cable entry suits applications where space allows linear routing. Verify current ratings and insulation resistance values in the technical specifications. Consider the operating temperature range relative to the intended deployment environment.

Part Context

This part falls under the Amphenol 38999 family of high-density circular connectors. These components are widely used in aerospace and defense sectors due to their rugged construction. The 71- prefix indicates a specific manufacturer coding convention for this series. It serves as a critical interface point in complex electronic assemblies requiring reliable signal integrity.

Replacement Considerations

Cross-reference with other manufacturers offering MIL-DTL-38999 compliant parts. Verify dimensional compatibility for panel cutouts and mounting hardware. Ensure mating interfaces align with existing cable assemblies and receptacle housings.
