71-433338-01R

Overview

The Amphenol Aerospace Operations 71-433338-01R is a circular MIL-spec connector plug belonging to the MIL-DTL-38999 Series III family. It features an aluminum alloy shell with electroless nickel plating and a straight cable mount installation style. The component utilizes a threaded coupling mechanism and crimp termination for reliable signal transmission. It supports 100 positions with male pin contacts, offering a current rating of 3 A and voltage ratings of 400 VAC or 500 VDC. The contacts are gold-plated copper alloy, ensuring durability in harsh environments.

Feature Summary

• Constructed with a durable aluminum alloy housing featuring protective electroless nickel plating for corrosion resistance.
• Utilizes a threaded coupling interface to ensure secure connection integrity under vibration and shock conditions.
• Designed with crimp-style termination for robust electrical contact stability and mechanical retention of wires.

Applications

• Military avionics systems requiring high-density interconnects
• Naval shipboard communication and control equipment
• Ground vehicle electronic warfare suites

Procurement Notes

Verify the specific suffix codes against the manufacturer's latest datasheet to confirm exact contact arrangements and environmental sealing options. Ensure compatibility with mating receptacles within the same MIL-DTL-38999 Series III designation. Confirm that the crimp tooling matches the specified contact size for proper termination quality.

Selection Notes

Select this model when a high-pin-count circular connector is required for cable-mounted applications. The straight configuration suits space-constrained enclosures where axial clearance is limited. Verify that the operating temperature range and environmental sealing requirements align with the standard specifications provided in the official documentation.

Part Context

This part belongs to the extensive MIL-DTL-38999 Series III product line from Amphenol Aerospace. These connectors are engineered for demanding defense and aerospace sectors, replacing older MIL-C-26482 designs with improved performance and higher density capabilities. The series is widely recognized for its reliability in extreme operational conditions.

Replacement Considerations

Cross-reference with legacy part numbers such as 87-433338-01R if substituting older inventory. Ensure that any replacement maintains the same shell size, insertion arrangement, and contact type to guarantee physical and electrical interchangeability without redesigning the harness.

FAQ

What is the primary locking mechanism for this connector?

The connector uses a threaded coupling nut to secure the connection between the plug and receptacle.

Is this connector shielded?

Yes, the aluminum alloy shell provides electromagnetic interference shielding for the internal contacts.
