WTA20SAD9JL-B82

Overview

The WTA20SAD9JL-B82 is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It is a receptacle with 20 positions arranged in two rows, designed for board mount installation via through-hole termination. The component features gold-plated copper alloy socket contacts and a Polyphenylene Sulfide (PPS) housing. Key electrical parameters include a 5 A current rating, 1 kV voltage rating, and 5 GOhms insulation resistance. It operates within a temperature range of -65 C to +125 C, utilizes a 2.54 mm pitch, and supports 22 AWG wire gauge.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for high-reliability interconnects.
• Utilizes gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance.
• Constructed with Polyphenylene Sulfide (PPS) housing for thermal stability.
• Designed for straight, vertical board mounting without integrated mounting ears.

Applications

• Avionics control and display systems
• Spacecraft and satellite electronics
• Missile guidance and electronic warfare equipment
• Shipboard communication systems

Procurement Notes

Verify the specific suffix B82 against official manufacturer documentation to confirm exact plating thickness or environmental sealing variations. Ensure compatibility with mating plugs such as the WTA20PD9JL series. Confirm RoHS compliance status directly with the supplier, as military variants may have specific regulatory exemptions. Validate that the straight receptacle form factor matches the PCB layout requirements.

Selection Notes

Select this part for applications requiring a 20-position, dual-row interface compliant with MIL-DTL-55302 standards. The choice of socket contacts necessitates pairing with a corresponding pin-type plug. Consider the PPS material properties for environments exceeding standard plastic limits. Verify that the 2.54 mm pitch aligns with existing board design constraints and that the through-hole termination method suits the manufacturing process.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors engineered for mission-critical sectors including aerospace and defense. The series is characterized by its rugged construction and adherence to strict military performance standards. The WTA designation specifically identifies a straight, two-row receptacle configuration within this family, ensuring interchangeability with other standardized military interconnect solutions.

Replacement Considerations

The part number alias M55302/64-B20F serves as a direct equivalent reference. When substituting, verify that the replacement unit maintains the same 20-position count, socket contact type, and MIL-DTL-55302 certification. Ensure the mating partner's physical dimensions and electrical ratings remain consistent with the original system design.
