MQD-36G-14

Overview

The Amphenol Aerospace MQD-36G-14 is a circular MIL-spec connector plug designed for high-reliability applications. It complies with MIL-DTL-38999 Series III standards and features a size 14 shell with a straight cable mount style. The unit utilizes a bayonet coupling mechanism and contains 15 positions configured with pin contacts. Constructed with an aluminum alloy housing finished in olive drab chromate over cadmium, it supports crimp termination for wire sizes ranging from 24 to 20 AWG. The contacts are gold-plated copper alloy, ensuring durability in demanding environments.

Feature Summary

• Complies with MIL-DTL-38999 Series III specifications for rigorous environmental performance
• Features a bayonet coupling system for rapid and secure connection engagement
• Utilizes a straight cable mount design for streamlined integration into assemblies

Applications

• Avionics systems requiring reliable signal transmission
• Military communication equipment interfaces
• Radar and navigation subsystems

Procurement Notes

Verify the specific contact configuration and shell finish against project requirements before ordering. Confirm that the supplier provides traceable documentation compliant with military standards. Ensure compatibility with mating receptacles regarding keying and insertion depth. Request manufacturer certificates of conformance to validate material specifications and plating integrity for critical deployments.

Selection Notes

Select this model when a Series III form factor is required with a size 14 shell and 15-pin arrangement. The straight cable mount orientation suits space-constrained installations where axial alignment is preferred. The gold-plated contacts offer superior conductivity and corrosion resistance compared to silver alternatives. Verify that the operating temperature range aligns with the component's specified environmental limits.

Part Context

This component belongs to the D38999 family of circular connectors, widely adopted in aerospace and defense sectors. It represents a third-generation iteration offering improved vibration resistance and sealing capabilities over previous series. The size 14 designation indicates a compact footprint suitable for moderate density wiring needs within constrained equipment bays.

Replacement Considerations

Compatible replacements include equivalent MIL-DTL-38999 Series III plugs from other manufacturers, provided they match the size 14 shell, 15-position layout, and bayonet coupling style. Cross-reference part numbers such as MS27473E14B37PB or similar equivalents to ensure dimensional and electrical interchangeability without modifying existing tooling.
