71-418624-35W

Overview

The Amphenol Aerospace Operations 71-418624-35W is a circular MIL-spec connector, specifically identified as the commercial equivalent of the MS3471L22-21SW. It belongs to the MIL-DTL-26482 Series II family and features an in-line receptacle configuration designed for cable mounting. The component utilizes a size 22 shell with a 22-21 insertion arrangement, accommodating 21 socket contacts. These contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. The termination method specified for this assembly is crimp, supporting robust mechanical connections within demanding aerospace environments.

Feature Summary

• In-line receptacle design compatible with MIL-DTL-26482 Series II standards
• Gold-plated copper alloy socket contacts for corrosion resistance
• Crimp termination style ensuring secure cable interface

Applications

• Commercial aerospace avionics systems
• Aircraft airframe power distribution
• Harsh environment instrumentation controls

Procurement Notes

Verify the specific suffix and insertion arrangement against the original military specification (MIL-DTL-26482) requirements before integration. Confirm that the crimp tooling matches the contact size specifications. Ensure environmental sealing requirements align with the intended application zone. Cross-reference the manufacturer's latest datasheet for any updated material compliance or RoHS status changes.

Selection Notes

Select this component when a commercial-grade alternative to the MS3471 series is required for weight-sensitive applications. The 21-position capacity suits complex signal routing needs. Verify shell size compatibility with existing panel cutouts. Ensure the crimp contact type matches the wire gauge used in the harness design. Consider the in-line orientation for space-constrained cable management layouts.

Part Context

This part number represents a commercial variant within the broader Amphenol MIL-DTL-26482 ecosystem. It serves as a direct functional substitute for the MS3471L22-21SW, maintaining identical electrical and mechanical interfaces while adhering to commercial manufacturing standards. The series is widely utilized in modern aircraft where reduced weight and simplified installation are critical design factors.

Replacement Considerations

The MS3471L22-21SW is the confirmed military-specification equivalent. Ensure mating connectors share the same shell size and insertion arrangement to maintain interface integrity.
