WTA20SAD7J

Overview

The AirBorn WTA20SAD7J is a rectangular MIL-DTL-55302 compliant receptacle connector from the W Series. It features 20 positions arranged in two rows with a 2.54 mm pitch. The component utilizes gold-plated copper alloy socket contacts and a Polyphenylene Sulfide (PPS) housing. Designed for board mount installation, it supports through-hole termination for 22 AWG wire. Electrical ratings include a current capacity of 5 A and a voltage rating of 1 kV. The unit operates within a temperature range of -65 C to +125 C and maintains an insulation resistance of 5 GOhms.

Feature Summary

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

Applications

• Military avionics systems requiring standardized rectangular connectors.
• Ruggedized electronic equipment operating in extreme temperature environments.
• Board-to-board interconnection in defense-grade instrumentation.

Procurement Notes

Verify the specific suffix codes against official Molex/AirBorn documentation to ensure correct contact orientation and hardware configuration. Confirm RoHS compliance status directly with the manufacturer as indicated in datasheets. Cross-reference the MIL-DTL-55302 type code to guarantee compatibility with mating plugs in mission-critical assemblies.

Selection Notes

Select this receptacle when a straight, two-row board-mount solution is required for 20 circuits. Ensure the mating plug corresponds to the specified pin or socket configuration. Verify that the 2.54 mm pitch and PPS material properties align with the thermal and mechanical constraints of the target PCB layout.

Part Context

This component belongs to the AirBorn W Series, a family of rectangular connectors designed for demanding applications. The series offers various contact counts and mounting styles while maintaining strict adherence to military standards. The WTA designation specifically identifies a straight receptacle without mounting ears.

Replacement Considerations

The part number alias M55302/64-B20F indicates potential cross-reference availability under government stock numbers. Verify exact dimensional and electrical equivalence before substituting with other manufacturers' offerings.
