71-433338-55T

Overview

The Amphenol Aerospace Operations part number 71-433338-55T is a circular MIL-spec connector plug belonging to the 38999 Aluminum series. It features an aluminum shell with a straight cable mount installation style and threaded mating interface. The connector provides 100 positions using pin (male) contacts that are gold-plated and made of copper. Designed for crimp termination, it operates within a voltage rating of 400 VAC and 500 VDC, supporting a current rating of 3 A per contact. The insertion arrangement is designated as 22-01.

Feature Summary

• Constructed with an aluminum alloy housing for durability in harsh environments
• Utilizes a threaded coupling mechanism for secure connection retention
• Employs gold-plated copper contacts to ensure reliable signal transmission
• Designed for direct cable mounting via crimp termination methods

Applications

• Avionics systems requiring high-density interconnects
• Military communication equipment interfaces
• Radar system signal distribution panels
• Ground vehicle electronic control units

Procurement Notes

Verify the specific datasheet revision and environmental qualification status before procurement. Confirm that the crimp tooling matches the specified contact size for proper termination. Ensure the receiving facility has the necessary ESD protection protocols. Cross-reference the manufacturer's latest obsolescence notices to confirm long-term availability. Validate that the shipping packaging meets military handling standards.

Selection Notes

Select this component when a high-pin-count circular connector is required for cable-to-panel or cable-to-cable applications. The straight design suits space-constrained installations where axial length is limited. The aluminum construction offers a favorable strength-to-weight ratio compared to steel alternatives. Verify that the operating environment temperature range aligns with the material specifications.

Part Context

This part belongs to the Amphenol 38999 series, a widely adopted family of circular connectors compliant with MIL-DTL-38999 standards. The series is characterized by its compact size and high density, making it suitable for modern aerospace and defense electronics. The aluminum variant specifically targets applications where weight reduction is critical without compromising mechanical integrity.

Replacement Considerations

The part number alias 87-433338-01E indicates potential cross-reference compatibility with legacy Mil-Spec numbering conventions. Verify dimensional interchangeability and contact alignment before substituting with other manufacturers' equivalents. Ensure that any replacement maintains the same threading standard and environmental sealing capabilities.
