71-433339-61E

Overview

The Amphenol Aerospace Operations 71-433339-61E is a circular MIL-spec connector belonging to the MIL-DTL-38999 Series III family. It is designed as a wall-mount receptacle with a bayonet coupling mechanism and straight cable entry. The housing is constructed from aluminum alloy with an electroless nickel plating for corrosion resistance. This component features 61 positions utilizing socket contacts, which are gold-plated for reliable signal transmission. The termination method specified is crimping, ensuring secure wire attachment. It operates within a temperature range of -55°C to +200°C and meets EREL qualification standards for harsh environment reliability.

Feature Summary

• Bayonet coupling system provides rapid connection and secure locking in high-vibration environments
• Electroless nickel plated aluminum shell ensures durability against corrosive conditions
• Gold-plated socket contacts maintain low contact resistance and signal integrity
• Wall-mount installation style facilitates direct panel integration

Applications

• Military avionics systems requiring rugged interconnects
• Naval shipboard electronic equipment
• Ground vehicle control units
• Harsh environment industrial instrumentation

Procurement Notes

Verify the specific suffix codes against the manufacturer's current datasheet to confirm exact contact arrangements and plating specifications. Ensure compatibility with mating plugs regarding shell size and keying options. Confirm that the crimp tooling matches the designated contact sizes for proper termination. Check for any updated environmental compliance declarations required by your procurement policy.

Selection Notes

Select this part when a high-density circular connector is needed for wall-mount applications. The Series III designation indicates enhanced performance over earlier generations. Verify that the bayonet style aligns with existing system maintenance requirements. Consider the operating temperature limits relative to the specific deployment environment. Ensure the crimp termination type matches the available wiring harness components.

Part Context

This component is part of the extensive MIL-DTL-38999 product line offered by Amphenol Aerospace. The series is widely recognized for its use in defense and aerospace sectors where reliability under extreme stress is critical. The 71 prefix typically denotes a receptacle configuration within the company's internal coding structure. It serves as a standard interface point for complex electrical networks in tactical and strategic platforms.

Replacement Considerations

Cross-reference with MS27466 or MS27505 series equivalents from other manufacturers if supply chain diversification is required. Ensure that physical dimensions and mounting hole patterns match exactly to avoid re-engineering. Verify that the mating plug utilizes the same bayonet coupling style for interchangeability.
