WTBV44PD9J

Overview

The WTBV44PD9J is a rectangular MIL Spec connector from the AirBorn W Series, manufactured by Molex. It functions as a board mount plug with 44 positions arranged in two rows. The component utilizes male pin contacts made of copper alloy with gold plating, designed for through-hole termination on printed circuit boards. It features a straight mounting angle and a polyphenylene sulfide (PPS) housing. Electrical specifications include a current rating of 5 A, a voltage rating of 1 kV, and an insulation resistance of 5 GOhms. The contact pitch is 2.54 mm, compatible with 22 AWG wire gauges, and it operates within a temperature range of -65 C to +125 C.

Feature Summary

• Compliant with MIL-DTL-55302 military standards for high-reliability applications
• Constructed with a durable polyphenylene sulfide (PPS) insulator body
• Features gold-plated copper alloy male pin contacts for secure signal transmission
• Designed for vertical board mounting via through-hole soldering

Applications

• Military and aerospace electronic systems requiring rugged interconnects
• High-density board-to-board communication interfaces
• Harsh environment instrumentation and control panels
• Avionics subsystems demanding strict reliability standards

Procurement Notes

Verify the specific manufacturer part number against official Molex/AirBorn documentation to ensure compatibility with system requirements. Confirm that the gold plating thickness and contact material meet the intended environmental durability needs. Check for any recent design changes or obsolescence notices directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a 44-position, dual-row male connector is required for MIL-DTL-55302 compliant designs. Ensure the PCB layout supports the 2.54 mm pitch and through-hole termination method. Verify that the operating temperature range of -65 C to +125 C aligns with the application's thermal profile and that the 5 A current rating suffices for the load.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors known for high density and reliability. The series includes various configurations of plugs and receptacles designed for mission-critical environments. The WTBV44PD9J specifically addresses the need for robust, multi-pin connections in space-constrained military and industrial assemblies.

Replacement Considerations

Cross-reference with other WTBV series variants for different position counts if 44 pins are unsuitable. Verify mechanical compatibility with mating receptacles such as the WTSB series. Ensure substitute parts maintain the same MIL-DTL-55302 compliance and electrical ratings.
