71-418624-19Y

Overview

The Amphenol Aerospace Operations part number 71-418624-19Y is a circular plug connector designed for military and aerospace applications. It complies with the MIL-DTL-26482 Series I standard, providing a robust interconnect solution for harsh environments. The connector features a size 16-8 shell with 8 positions, utilizing male pin contacts suitable for crimp termination. Constructed with an aluminum alloy housing finished in non-electroplated nickel, it offers a silver appearance. The unit is rated for operation between -55°C and +200°C and includes a coupling nut for secure attachment.

Feature Summary

• Complies with MIL-DTL-26482 Series I specifications for reliable performance in demanding conditions.
• Features a durable aluminum alloy housing with a corrosion-resistant non-electroplated nickel finish.
• Utilizes gold-plated copper alloy contacts for low resistance and high conductivity.
• Designed with a coupling nut mechanism to ensure secure mating and vibration resistance.

Applications

• Military avionics systems requiring standardized circular interconnects
• Aerospace instrumentation and control panels
• Harsh environment electronic equipment enclosures

Procurement Notes

Verify that the specific suffix 'Y' aligns with your environmental sealing or contact plating requirements, as variations exist within the 71-418624 series. Confirm compatibility with mating receptacles under MIL-DTL-26482 Series I standards. Ensure crimp tools match the specified contact sizes for proper termination integrity. Check for any updated RoHS compliance status if required by your supply chain regulations.

Selection Notes

Select this component when a Series I circular plug is required for panel-mount or free-hanging applications. The 8-position configuration suits moderate signal density needs. Verify that the operating temperature range of -55°C to +200°C meets your system's thermal profile. Ensure the non-shielded design is acceptable for your electromagnetic interference requirements.

Part Context

This connector belongs to the Amphenol MIL-DTL-26482 Series I family, widely used in defense and aerospace sectors. It serves as a direct replacement for legacy MS3470/MS3472 connectors. The series is known for its compact size and high reliability compared to older Series II counterparts, offering similar performance in a lighter package.

Replacement Considerations

Direct equivalents include MS3470L16-8P and MS3476L16-8P from other manufacturers adhering to MIL-DTL-26482 Series I. Verify dimensional interchangeability before substitution. Note that Series I connectors are not mechanically interchangeable with Series II without adapters.
