71-529701-98Z

Overview

The Amphenol Aerospace Operations connector, identified by manufacturer part number 71-529701-98Z and DigiKey reference 1178-JT08RP-8-98SD(318), is a circular plug component belonging to the JT series. It features a size 8 shell with 98 signal contacts and two coaxial positions. The unit utilizes a threaded coupling mechanism for secure engagement. Designed for harsh environments, it provides environmental sealing and shielding capabilities. The connector supports high-frequency applications through its coaxial contact configuration.

Feature Summary

• Self-locking threaded coupling mechanism ensures secure connection under vibration
• Integrated shielding provides electromagnetic interference protection
• Environmental sealing offers resistance to moisture and contaminants
• Coaxial contact configuration supports high-frequency signal transmission

Applications

• Avionics systems in commercial and defense aircraft
• Radar and communication equipment installations
• Harsh environment industrial control interfaces

Procurement Notes

Verify the specific suffix codes against official Amphenol documentation to confirm exact contact arrangements and material specifications. Ensure compatibility with mating receptacles regarding shell size and thread type. Confirm that the environmental sealing requirements match the operational conditions of the target application before finalizing procurement.

Selection Notes

Select this component when a robust, shielded circular connector is required for high-density signal routing. The size 8 shell offers a balance between contact count and physical footprint. Verify that the operating temperature range and voltage ratings align with system design constraints. Consider the threaded coupling for applications requiring high mechanical retention.

Part Context

This part belongs to the JT series of circular connectors manufactured by Amphenol Aerospace Operations. The JT series is widely used in aerospace and defense sectors for its reliability in extreme conditions. The specific model integrates both standard signal pins and coaxial contacts within a single housing, allowing mixed-signal connectivity in compact spaces.

Replacement Considerations

Cross-reference with equivalent MIL-DTL-38999 Series III connectors if military specification compliance is required. Verify dimensional compatibility with existing panel cutouts and mating interfaces. Ensure that the replacement maintains the same shielding effectiveness and environmental sealing rating.
