71-529701-98T

Overview

The 71-529701-98T is a circular MIL-spec connector plug manufactured by Amphenol Aerospace Operations. It features a size 8 shell with a bayonet coupling mechanism and contains 98 socket contacts. The housing is constructed from aluminum alloy with a nickel electroless plating finish. Contacts are designed for crimp termination using size 20 wire. This component complies with MIL-DTL-38999 Series I standards, providing environmental sealing capabilities for harsh aerospace applications.

Feature Summary

• Bayonet coupling system for rapid engagement and secure locking
• Aluminum alloy shell with nickel plating for corrosion resistance
• Crimp termination design for reliable electrical connections
• MIL-DTL-38999 Series I compliance for environmental sealing

Applications

• Commercial aircraft avionics systems
• Military defense electronic equipment
• Aerospace instrumentation and control circuits
• Harsh environment signal distribution

Procurement Notes

Verify the specific contact configuration and shell size against the official datasheet before procurement. Ensure compatibility with mating receptacles regarding coupling type and contact gender. Confirm that the supplier provides genuine Amphenol Aerospace Operations products to guarantee MIL-DTL-38999 compliance and material specifications.

Selection Notes

Select this model when a size 8 shell with 98 sockets is required in a bayonet-coupled assembly. Consider the aluminum construction for weight-sensitive applications where nickel plating offers sufficient environmental protection. Verify that the crimp tooling matches the specified contact size for proper termination integrity.

Part Context

This part belongs to the Amphenol 38999 series of circular connectors, widely used in aerospace and defense industries. The series is known for its high density and rugged performance. The 71- prefix typically denotes a specific manufacturer code or revision within the broader MIL-spec ecosystem, ensuring traceability and standard compliance.

Replacement Considerations

Cross-reference with MS27467E8S98SB or similar MIL-DTL-38999 Series I equivalents. Ensure exact match in shell size, contact count, and coupling style. Verify that substitute parts maintain the same environmental sealing ratings and material composition for critical installations.
