WTA36SAD9J

Overview

The WTA36SAD9J is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It is a straight receptacle designed for board mount installation with 36 positions arranged in two rows. The component features through-hole termination and gold-plated copper alloy socket contacts. Rated for 5 A current and 1 kV voltage, it operates within a temperature range of -65 C to +125 C. The housing is constructed from polyphenylene sulfide (PPS), providing an insulation resistance of 5 GOhms. The contact pitch is 2.54 mm, suitable for 22 AWG wire.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for high-reliability interconnects
• Utilizes gold-plated copper alloy contacts for durable signal transmission
• Constructed with polyphenylene sulfide housing for thermal stability
• Designed for secure board mounting via through-hole soldering

Applications

• Military aerospace electronic systems
• Avionics equipment interfaces
• Ruggedized defense communication hardware
• High-density board-to-board connections in harsh environments

Procurement Notes

Verify the manufacturer part number against official Molex or AirBorn documentation to ensure authenticity. Confirm that the specific suffix matches the required contact configuration and plating specifications. Check RoHS compliance status if environmental regulations apply to the assembly. Ensure the procurement source provides valid traceability certificates for military-grade components.

Selection Notes

Select this component when a 36-position straight receptacle is required for MIL-DTL-55302 applications. Ensure the mating plug corresponds to the correct gender and pin count. Verify that the PCB layout accommodates the 2.54 mm pitch and through-hole footprint. Confirm that the operating environment remains within the specified -65 C to +125 C temperature range for optimal performance.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for mission-critical applications. The series offers various contact counts and configurations to support high-density interconnect needs in demanding sectors. The WTA designation specifically indicates a two-row straight receptacle without mounting ears, distinguishing it from panel-mount or cable-mount variants within the same family.

Replacement Considerations

The part number alias M55302/64-B36X may serve as a cross-reference. Verify mechanical dimensions and electrical ratings before substituting with other manufacturers' equivalents to ensure compatibility with existing mating connectors and PCB designs.
