71-433338-32E

Overview

The Amphenol Aerospace Operations model 71-433338-32E is a circular MIL-spec connector plug. It features an aluminum shell in size 32 with a straight cable mount installation style. The component utilizes a threaded mating style and crimp termination for contacts. It contains 5 positions configured as male pins. The electrical ratings include a current capacity of 15 A, a voltage rating of 400 VAC or 500 VDC. The contacts are gold-plated copper. This part complies with the MIL-DTL-38999 standard.

Feature Summary

• Constructed with a durable aluminum alloy housing for structural integrity in harsh environments.
• Utilizes a threaded coupling mechanism to ensure secure connection retention under vibration.
• Features gold-plated copper contacts designed for reliable signal transmission and corrosion resistance.
• Designed for direct cable mounting using a crimp termination method for robust wire attachment.

Applications

• Avionics systems requiring MIL-DTL-38999 compliance
• Defense communication equipment
• Radar system interconnects
• Harsh environment industrial control panels

Procurement Notes

Verify the specific suffix codes against the manufacturer's latest datasheet to confirm contact plating thickness and environmental sealing options. Ensure the crimp tooling matches the specified contact size for proper termination. Cross-reference the MIL-DTL-38999 series designation to confirm compatibility with existing mating receptacles in the assembly. Check for any updated RoHS or REACH compliance statements relevant to the manufacturing batch.

Selection Notes

Select this component when a high-density circular connector is required for cable-to-cable or cable-to-panel connections. The size 32 shell provides ample space for multiple circuits while maintaining a compact profile. The threaded interface offers superior retention compared to bayonet styles, making it suitable for applications with high mechanical stress. Verify that the crimp contact gauge aligns with the wire harness specifications.

Part Context

This part belongs to the MIL-DTL-38999 Series I family of circular connectors. These connectors are widely used in aerospace and defense sectors due to their standardized dimensions and performance capabilities. The series offers various shell sizes and contact arrangements to accommodate diverse wiring needs. Aluminum shells provide a balance of weight reduction and shielding effectiveness.

Replacement Considerations

Equivalent parts may include those from other manufacturers adhering to MIL-DTL-38999 standards. Verify dimensional interchangeability and contact arrangement before substitution. Ensure the replacement meets the same voltage and current ratings. Check for compatible mating interfaces and mounting configurations.
