71-419576-02P

Overview

The Amphenol Aerospace Operations part number 71-419576-02P is a circular MIL-spec connector receptacle. It belongs to the MS3470 series and features an in-line cable mount configuration. The unit utilizes a size 20 shell with a 20-41 insertion arrangement, providing 41 positions for socket contacts. The contacts are gold-plated copper alloy designed for crimp termination. This component is rated for 7.5 amperes and complies with MIL-DTL-26482 Series II standards.

Feature Summary

• Provides high-density signal distribution through a 41-position socket interface within a compact cylindrical housing.
• Ensures reliable electrical connectivity via gold-plated copper alloy contacts suitable for crimp termination processes.
• Facilitates secure cable integration using an in-line mounting style with strain relief capabilities.

Applications

• Avionics systems requiring robust interconnect solutions
• Military communication equipment interfaces
• Radar system signal routing assemblies

Procurement Notes

Verify the specific suffix codes against official Amphenol documentation to confirm contact orientation and environmental sealing ratings. Ensure compatibility with mating plugs regarding shell size and insertion arrangement. Confirm that the crimp tooling matches the specified contact gauge requirements for proper termination integrity.

Selection Notes

Select this component when a high-pin-count receptacle is required for MIL-DTL-26482 compliant applications. Evaluate the need for gold plating versus other finishes based on corrosion resistance requirements. Consider the physical constraints of the in-line cable entry relative to available chassis space and cable bend radius limitations.

Part Context

This part falls under the MS3470 series of lightweight circular connectors manufactured by Amphenol Aerospace. These connectors are engineered for demanding environments where weight savings and durability are critical. The series supports various insertion arrangements to accommodate diverse wiring harness configurations across aerospace and defense platforms.

Replacement Considerations

Cross-reference with MS3471L20-41SW for equivalent socket configurations. Verify mechanical fit and electrical continuity before substituting with generic equivalents or alternative manufacturer parts from the same MIL-SPEC family.
