WTB44SOR9J

Overview

The WTB44SOR9J is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It functions as a board mount receptacle with socket contacts, designed for right-angle through-hole termination. The component features a dual-row configuration with 44 positions and a 2.54 mm pitch. Constructed with a Polyphenylene Sulfide (PPS) body and gold-plated copper alloy contacts, it meets MIL-DTL-55302 standards. Rated for 5 A current and 1 kV voltage, it operates between -65 °C and +125 °C with an insulation resistance of 5 GOhms.

Feature Summary

• Right-angle board mount receptacle design with fixed jackset and mounting ears
• Gold-plated copper alloy socket contacts ensuring reliable signal transmission
• Polyphenylene Sulfide (PPS) housing providing thermal stability and durability
• Compliance with MIL-DTL-55302 military specifications for harsh environments

Applications

• Military avionics control systems
• Aerospace electronic interconnections

Procurement Notes

Verify the specific suffix '9J' against the official Molex/AirBorn datasheet to confirm exact tail length and jackset configuration. Ensure compatibility with mating plug series WTB44PR9J. Confirm RoHS status and lead times directly with the manufacturer, as this item may be subject to special order requirements or distribution restrictions in certain regions.

Selection Notes

Select this part for applications requiring high-density I/O in constrained spaces due to its right-angle form factor. The 44-position count suits complex signal routing needs. Verify that the PCB layout accommodates the right-angle orientation and through-hole soldering profile. Ensure the operating environment stays within the specified temperature range and voltage ratings defined in the technical documentation.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors known for meeting stringent MIL-DTL-55302 standards. The series offers various configurations including plugs and receptacles with different contact counts and orientations. The WTB44SOR9J specifically addresses the need for robust, high-pin-count connections in aerospace and defense sectors where reliability under vibration and thermal stress is critical.

Replacement Considerations

Compatible substitutes include the M55302/61B44 designation. Cross-reference with other W Series variants like WTB44SAD9J for straight-body alternatives if space permits. Verify pinout and mechanical dimensions before substituting.
