71-430578-08S

Overview

The Amphenol Aerospace Operations model 71-430578-08S is a circular MIL-spec connector plug designed for robust interconnect applications. It features an 8-position configuration with socket contacts, utilizing a size 08 shell. The component adheres to the MIL-DTL-38999 Series III standard and employs a crimp termination method for reliable electrical connections. Constructed with a composite housing material, it offers durability in demanding environments. The unit is equipped with gold-plated copper alloy contacts to ensure low resistance and corrosion resistance. This straight-mount cable plug is intended for secure mating with compatible receptacles in aerospace and defense systems.

Feature Summary

• MIL-DTL-38999 Series III compliance for standardized military-grade performance
• Gold-plated copper alloy socket contacts for enhanced conductivity
• Composite shell construction providing lightweight durability
• Crimp termination style ensuring secure wire attachment

Applications

• Military avionics systems
• Naval shipboard equipment
• Radar and communication arrays
• Test and measurement instrumentation

Procurement Notes

Verify the specific contact arrangement and shell plating options against the official datasheet before ordering. Confirm that the crimp tooling matches the specified contact sizes. Ensure environmental sealing requirements align with the IP rating of the mating receptacle. Check for any restricted substance declarations if operating in regulated markets. Validate compatibility with existing cable harness assemblies.

Selection Notes

Select this component when a compact, high-density circular connector is required for cable-to-panel or cable-to-cable interfaces. Consider the composite material for weight-sensitive applications where aluminum shells are not mandatory. Ensure the mating environment does not exceed the temperature ratings defined in the specification. Verify that the straight mounting style fits within the available spatial constraints of the enclosure.

Part Context

This part belongs to the extensive family of MIL-DTL-38999 connectors manufactured by Amphenol Aerospace. These connectors are widely used across defense and aerospace sectors due to their interchangeability and rugged design. The Series III designation indicates a specific shell size and contact density range within the broader standard. Amphenol's production ensures consistent quality for critical mission-critical systems.

Replacement Considerations

Compatible substitutes include equivalent MIL-DTL-38999 Series III plugs from other qualified manufacturers such as Glenair or ITT Cannon, provided they meet the same dimensional and electrical specifications. Cross-referencing the exact contact arrangement number is essential to ensure pinout compatibility. Verify that alternative sources offer the same composite shell and gold plating options.
