71-433338-21Z

Overview

The Amphenol Aerospace Operations part number 71-433338-21Z is a circular MIL-spec connector plug belonging to the 38999 series. It features an aluminum shell with size 22 and utilizes a threaded mating style for secure connection. The component is designed for cable installation and employs crimp termination methods for reliable electrical contact. Official documentation identifies this specific part as a variant of the JT06RP-22-21SD(003)(LC) configuration, indicating it is a socket-type receptacle interface intended for mating with pin contacts in demanding environments.

Feature Summary

• Constructed with a durable aluminum alloy housing suitable for rugged operational conditions
• Utilizes a threaded coupling mechanism to ensure secure and vibration-resistant connections
• Designed for direct cable mounting with crimp-style termination for signal integrity

Applications

• Aerospace avionics systems requiring MIL-DTL-38999 compliance
• Industrial control panels needing robust circular interconnects
• Defense equipment installations subject to harsh environmental factors

Procurement Notes

Verify the exact suffix codes against the manufacturer's current datasheet to confirm terminal type and plating specifications. Ensure compatibility with existing mating connectors regarding shell size and thread engagement. Cross-reference the internal part number 71-433338-21Z with the standard JT06RP series nomenclature to avoid ordering errors due to legacy naming conventions.

Selection Notes

Select this component when a shielded, cable-mount plug with threaded coupling is required for high-reliability applications. Confirm that the mating counterpart provides the appropriate pin configuration for the circuit design. Evaluate the environmental sealing requirements against the connector's inherent design capabilities before finalizing the selection for critical infrastructure projects.

Part Context

This part belongs to the extensive family of Amphenol 38999 series circular connectors, widely recognized for their miniaturization and high density. The 38999 series serves as a successor to older MIL-C-26482 designs, offering improved performance in smaller form factors. This specific model represents a standard industrial and aerospace grade solution within that lineage.

Replacement Considerations

Direct substitutes include equivalent parts from other manufacturers complying with MIL-DTL-38999 Series I or II standards. Verify dimensional interchangeability and electrical ratings before substitution. Legacy equivalents may carry different base part numbers but must match the shell size 22 and threaded interface characteristics.
