71-433033-04Y

Overview

The 71-433033-04Y is a circular MIL-spec connector manufactured by Amphenol Aerospace Operations. It belongs to the JT series and complies with MIL-DTL-26482 Series I standards. The component functions as a plug with a straight cable mount installation style. It features an aluminum shell with cadmium plating and utilizes a threaded mating style for secure connection. The unit provides 4 positions configured for pin contacts, which are silver-plated copper alloy terminals terminated via solder. This design supports reliable signal transmission in demanding environments.

Feature Summary

• Complies with MIL-DTL-26482 Series I military specifications for ruggedized performance
• Features a threaded coupling mechanism for secure environmental sealing
• Constructed with an aluminum housing protected by cadmium electroplating
• Utilizes silver-plated copper alloy contacts for low resistance termination

Applications

• Military avionics systems requiring certified interconnects
• Defense communication equipment installations
• Ruggedized industrial control panels
• Aerospace wiring harness assemblies

Procurement Notes

Verify the specific suffix code against official manufacturer documentation to confirm exact contact arrangement and plating specifications. Ensure compatibility with corresponding receptacle models within the same MIL-DTL-26482 Series I family. Confirm that the threaded coupling style matches the intended panel or cable assembly requirements before finalizing procurement orders.

Selection Notes

Select this component when a circular connector compliant with MIL-DTL-26482 Series I is required for cable-mounted applications. The 4-position configuration suits low-pin-count signal routing needs. The aluminum construction offers weight advantages over steel alternatives while maintaining structural integrity. Verify that the operating environment temperature range aligns with the standard material capabilities of the specified plating and insulation materials.

Part Context

This part is part of the broader JT series of circular connectors produced by Amphenol Aerospace Operations. The series is widely recognized for its compliance with stringent military standards, ensuring reliability in harsh operational conditions. The 71-433033-04Y designation specifically identifies the physical size, contact count, and mounting style within this extensive product line used across defense and aerospace sectors.

Replacement Considerations

Cross-reference with equivalent parts from other manufacturers holding MIL-DTL-26482 certification. Verify dimensional interchangeability and electrical continuity with existing system components. Ensure that any substitute maintains the same shell size and contact arrangement to fit existing enclosures without modification.
