71-418618-68R

Overview

The Amphenol Aerospace Operations part number 71-418618-68R is a circular MIL-spec connector plug. It belongs to the JT06RE series and complies with MIL-DTL-38999 standards. The unit features an aluminum alloy shell in size 18 with a straight cable mount style. It utilizes a crimp termination method for contact attachment. The connector provides 18 positions arranged according to insertion code 18-68. Contacts are male pins made of copper alloy, finished with gold plating. The assembly supports a current rating of 13 A and operates at voltage ratings up to 600 VAC or 850 VDC.

Feature Summary

• Constructed with a durable aluminum alloy housing for structural integrity
• Features threaded mating interface for secure connection retention
• Utilizes gold-plated copper alloy contacts for reliable signal transmission
• Designed for direct cable installation using crimp termination techniques

Applications

• Avionics systems in military aircraft
• Aircraft airframe power distribution networks
• Harsh environment instrumentation controls
• Defense communication equipment interconnects

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct contact arrangement and environmental sealing specifications. Confirm that the requested item matches the exact MIL-DTL-38999 compliance requirements for your application. Cross-reference the insertion code to validate pin configuration compatibility with existing mating receptacles before finalizing procurement orders.

Selection Notes

Select this component when a straight-mount MIL-DTL-38999 Series III plug is required for size 18 applications. Ensure the system design accommodates the 13 A current capacity and 600 VAC voltage rating. Verify that the crimp termination process aligns with available tooling and wire gauge constraints. Confirm that the aluminum housing material meets corrosion resistance needs for the intended operational environment.

Part Context

This part is manufactured by Amphenol Aerospace Operations under the JT06RE product line. It serves as a replacement or equivalent for legacy part numbers such as 71-418618-68R within the MIL-DTL-38999 ecosystem. The connector is designed for high-reliability applications requiring robust mechanical performance and consistent electrical continuity in demanding conditions.

Replacement Considerations

Direct substitutes include JT06RE-18-68PB(301) and JT06RE-18-68PD(SR). Verify cross-compatibility with mating receptacles having matching insertion codes and shell sizes before implementation.
