71-418624-19Z

Overview

The Amphenol Aerospace Operations part number 71-418624-19Z is a circular MIL-spec connector plug. It features 19 positions with socket contacts. The shell size is 24, utilizing a straight cable mount installation style. The connector complies with MIL-DTL-38999 Series III standards. It employs a self-locking coupling mechanism for secure engagement. The housing material is aluminum alloy with zinc nickel plating for corrosion resistance. Contacts are gold-plated copper alloy designed for crimp termination.

Feature Summary

• Self-locking coupling mechanism ensures secure connection in high-vibration environments
• Cable mount design allows direct attachment to wire harnesses without panel penetration
• Gold-plated contacts provide reliable signal transmission and low contact resistance

Applications

• Avionics systems requiring MIL-DTL-38999 compliance
• Aircraft wiring harness interconnections
• Defense electronics equipment cabling

Procurement Notes

Verify the specific suffix codes against official Amphenol datasheets to confirm exact contact arrangements and environmental sealing ratings. Ensure compatibility with mating receptacles regarding shell size and coupling type. Cross-reference the manufacturer part number with industry standard equivalents to validate supply chain authenticity and technical specifications before procurement.

Selection Notes

Select this component when a self-locking circular connector is required for cable-mounted applications. Verify that the system environment supports the operating temperature range specified in the datasheet. Confirm that the mating interface utilizes compatible socket contacts and that the cable diameter accommodates the strain relief requirements of the shell size 24 housing.

Part Context

This part belongs to the D38999 Series III family of circular connectors. These connectors are widely used in aerospace and defense industries due to their rugged construction and standardized dimensions. The series offers various shell sizes and contact arrangements to meet diverse interconnection needs while maintaining strict military specification compliance for reliability.

Replacement Considerations

Equivalent parts include MS3470W24-19SZ and DT06-24-19SD. Verify dimensional compatibility and contact arrangement alignment before substitution. Ensure the replacement maintains the same self-locking coupling mechanism and environmental sealing characteristics as the original component.
