71-433034-37F

Overview

The 71-433034-37F is a circular MIL-spec connector plug manufactured by Amphenol Aerospace Operations. It complies with the MIL-DTL-38999 series III standard and serves as an alternative designation for part number JT06RE-14-37SA(318). The component features a size 14 shell constructed from aluminum alloy, finished with a cadmium electroplating for corrosion resistance. It utilizes a threaded coupling mechanism to ensure secure mating in high-vibration environments. The internal contacts are silver-plated copper alloy pins designed for reliable signal transmission.

Feature Summary

• Compliant with MIL-DTL-38999 Series III military specifications for rugged performance
• Threaded coupling design ensures secure connection under vibration
• Cadmium-plated aluminum alloy housing provides environmental protection
• Silver-plated copper alloy contacts support consistent electrical conductivity

Applications

• Avionics systems in military aircraft
• Radar equipment interconnections
• Weapon system control panels
• Ground-based military communication infrastructure

Procurement Notes

Verify the exact manufacturer source, as this part number may be sourced through authorized distributors or direct aerospace channels. Confirm that the received unit matches the specific suffix codes for contact arrangement and plating. Ensure compliance with current export control regulations if applicable. Request original certification documents to validate authenticity against counterfeit risks common in military-grade components.

Selection Notes

Select this component when a MIL-DTL-38999 Series III plug is required for size 14 applications. The choice depends on the need for a threaded coupling style rather than bayonet or quick-connect variants. Verify that the pin configuration aligns with the mating receptacle's socket layout. Consider the cadmium plating requirement for specific environmental conditions versus other available finishes.

Part Context

This connector belongs to the extensive family of circular connectors defined by MIL-DTL-38999. It represents the third generation (Series III) of these standards, offering higher density and improved durability compared to earlier versions. The part is integral to defense electronics, providing standardized interfaces for critical data and power lines in harsh operational settings where reliability is paramount.

Replacement Considerations

The part number JT06RE-14-37SA(318) is explicitly listed as an alias for 71-433034-37F. Substitution should strictly involve this equivalent designation to maintain mechanical and electrical compatibility. Cross-brand replacements require careful verification of pinout diagrams and mounting dimensions.
