71-419576-02S

Overview

The Amphenol Aerospace Operations model 71-419576-02S is a circular connector assembly designed for high-reliability aerospace and defense applications. This specific part number denotes a receptacle configuration featuring a shell size of 02 with a solder termination method for the contacts. The connector utilizes a robust metal housing, typically constructed from aluminum alloy or stainless steel, to provide mechanical durability and electromagnetic interference shielding in demanding environments. It is engineered to meet stringent military specifications, ensuring consistent performance under extreme temperature variations, vibration, and shock conditions common in avionics and radar systems.

Feature Summary

• High-density contact arrangement within a compact shell size for space-constrained installations
• Solder cup termination ensures secure electrical connections resistant to vibration-induced loosening
• Metal shell construction provides structural integrity and effective environmental sealing capabilities

Applications

• Avionics control units requiring reliable signal transmission
• Radar system interconnects subject to high-vibration environments
• Military communication equipment housings

Procurement Notes

Verify the exact mating counterpart compatibility before procurement, as circular connector series often require matching plugs with specific keying options to prevent misalignment. Confirm that the solder termination type aligns with your printed circuit board or cable harness manufacturing processes. Ensure that the environmental seal requirements match the operational environment, as some variants may lack integrated gaskets unless specified. Cross-reference the drawing numbers to guarantee dimensional accuracy for panel cutouts.

Selection Notes

Select this component based on the required shell size and contact count availability within the 71 series. Evaluate the need for additional environmental protection features such as backshells or strain reliefs if the standard receptacle does not suffice. Consider the operating temperature range and ensure the material selection meets the specific corrosion resistance needs of the deployment site. Verify that the chosen variant supports the necessary current ratings for the intended circuit loads without overheating.

Part Context

This part belongs to the Amphenol 71 series of circular connectors, widely recognized in the aerospace sector for their rugged design. The series offers various shell sizes and contact configurations to accommodate diverse wiring needs. The 71 series is known for its compliance with MIL-DTL-38999 standards, providing interchangeability with other manufacturers' products while maintaining high performance. This specific model represents a standard receptacle form factor used extensively in fixed installations.

Replacement Considerations

Compatible substitutes include equivalent MIL-DTL-38999 Series I receptacles from manufacturers such as Glenair or ITT Cannon, provided the shell size, contact arrangement, and mounting style are identical. Verify that any replacement part maintains the same critical dimensions and interface specifications to ensure seamless integration into existing assemblies without modification.
