Overview

The WTA20SACJTA-B82 is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It is a receptacle featuring 20 positions arranged in two rows with a 2.54 mm pitch. The component utilizes gold-plated copper alloy socket contacts and terminates via through-hole soldering. Designed for board mount installation, 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 and a voltage rating of 1 kV.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for high-reliability interconnects
• Features gold-plated copper alloy contacts for durable signal transmission
• Constructed with Polyphenylene Sulfide (PPS) housing for thermal stability

Applications

• Military avionics systems
• Ruggedized electronic equipment
• Board-to-board interconnection in harsh environments

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with mating plugs. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region. Ensure the ordering part number matches the required contact termination style and housing orientation.

Selection Notes

Select this component when a straight-mount receptacle with 20 socket positions is required for MIL-Spec applications. Verify that the mating plug corresponds to the WTA series with compatible contact types. Ensure the PCB layout accommodates the 2.54 mm pitch and through-hole termination requirements while respecting the operating temperature limits.

Part Context

This part belongs to the AirBorn W Series, a family of rectangular connectors designed for demanding environments. The series offers various contact counts and termination options, standardized under MIL-DTL-55302. The WTA variant specifically denotes a straight-mount receptacle configuration without mounting ears, ensuring compact integration into panel or board assemblies.

Replacement Considerations

Compatible substitutes include other WTA-series receptacles with identical pin counts and termination styles, such as WTA20SAD9JTA-B82 or WTA20SAW40JTA-B82, provided the contact type and housing material remain consistent.
