WTAV40PD9JL-D54

Overview

The WTAV40PD9JL-D54 is a rectangular MIL-Spec board mount plug from the AirBorn W Series, manufactured by Molex. It features 40 positions arranged in two rows with a 2.54 mm pitch. The connector utilizes male pin contacts made of copper alloy with gold plating, terminated via through-hole soldering. Rated for 5 A current and 1 kV voltage, it operates between -65 °C and +125 °C. The housing is constructed from Polyphenylene Sulfide (PPS), providing high insulation resistance of 5 GOhms. This component complies with MIL-DTL-55302 standards.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for reliable performance in demanding environments
• Features gold-plated copper alloy pin contacts to ensure stable signal transmission and corrosion resistance
• Utilizes Polyphenylene Sulfide (PPS) housing material for thermal stability and mechanical durability

Applications

• Military avionics systems requiring certified interconnect solutions
• Ruggedized electronic equipment operating in extreme temperature ranges
• High-reliability industrial control boards needing standardized MIL-spec interfaces

Procurement Notes

Verify the complete part number including the D54 suffix against official Molex/AirBorn documentation to confirm specific tail length and jackset configurations. Ensure compatibility with mating receptacles within the same W Series family. Cross-reference the MIL-DTL-55302 designation to validate regulatory compliance requirements for your specific application environment before finalizing procurement.

Selection Notes

Select this model when a straight, two-row board mount plug with 40 circuits is required. Confirm that the through-hole termination method aligns with your PCB fabrication capabilities. Verify that the 2.54 mm pitch matches your layout constraints. Ensure the 5 A current rating per contact is sufficient for your circuit design. Check that the PPS housing material meets your environmental exposure needs.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for high-density applications. The series offers various contact counts and termination options while maintaining strict adherence to military standards. The WTA/WTAV prefix indicates specific plug configurations within this robust family of interconnect products.

Replacement Considerations

Equivalent parts include M55302/56B40JL or other MIL-DTL-55302 compliant 40-position plugs. Verify dimensional compatibility and contact orientation before substitution. Ensure the replacement maintains the same gold plating thickness and PPS housing material properties.
