71-419746-03P

Overview

The Amphenol Aerospace Operations part number 71-419746-03P, also identified as PT08CP-8-3P(LC), is a circular plug connector belonging to the PT series. This component serves as a direct equivalent to the MIL-DTL-26482 Series I standard, specifically aligning with MS26448 specifications for military applications. The connector features an aluminum alloy shell plated in olive drab cadmium to provide corrosion resistance and durability in harsh environments. It utilizes a bayonet coupling mechanism for secure attachment and includes a strain relief feature indicated by the LC suffix. The design supports reliable signal transmission in defense and aerospace systems requiring compact, high-density interconnect solutions.

Feature Summary

• Bayonet coupling mechanism ensures rapid and secure connection engagement
• Aluminum alloy shell construction provides structural integrity and weight efficiency
• Olive drab cadmium plating offers enhanced corrosion resistance
• Strain relief design accommodates cable management requirements

Applications

• Avionics systems in military aircraft
• Ground vehicle communication equipment
• Naval radar and sensor interfaces
• Missile guidance system wiring

Procurement Notes

Verify that the specific order corresponds to the PT08CP-8-3P(LC) designation to ensure compatibility with MIL-DTL-26482 Series I standards. Confirm the presence of the LC strain relief feature if cable support is required for the installation environment. Cross-reference the shell material and plating specifications to guarantee suitability for the intended operational conditions. Ensure all documentation matches the Amphenol Aerospace Operations manufacturing records.

Selection Notes

Select this connector when a Series I equivalent to MIL-DTL-26482 is required rather than the heavier Series II standard. Consider the aluminum shell and bayonet lock for applications where weight savings and quick mating cycles are prioritized over the higher environmental sealing of Series II. Verify that the pin configuration meets the circuit requirements without needing additional adapter solutions.

Part Context

This component belongs to the PT series of circular connectors manufactured by Amphenol Aerospace Operations. It functions as a commercial and military-grade alternative to the MS26448 family, offering similar electrical and mechanical performance within a lighter form factor. The part is distinct from the heavier MIL-DTL-26482 Series II connectors, providing a specialized solution for space-constrained defense applications.

Replacement Considerations

The part is functionally equivalent to MS26448 style connectors. Direct substitutes include other manufacturers' offerings conforming to MIL-DTL-26482 Series I specifications. Verify interface dimensions and coupling torque before substituting with non-Amphenol parts.
