WTB20PR9SY-D01

Overview

The WTB20PR9SY-D01 is a rectangular MIL-spec connector plug from the AirBorn W Series, manufactured by Molex. It features 20 positions arranged in two rows with male pin contacts. Designed for board mount installation, it utilizes through-hole termination and offers a right-angle orientation. The component has a 2.54 mm pitch and gold-plated copper alloy contacts within a Polyphenylene Sulfide (PPS) body. It supports a current rating of 5 A and voltage rating of 1 kV, operating between -65 C and +125 C.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for high reliability.
• Features gold-plated copper alloy pin contacts for durable conductivity.
• Constructed with Polyphenylene Sulfide housing for thermal stability.
• Includes guide sets and mounting ears for secure PCB integration.

Applications

• Military avionics systems
• Ruggedized electronic enclosures
• High-reliability industrial control boards

Procurement Notes

Verify the specific suffix D01 to confirm inclusion of guide sets and mounting ears, as these physical attributes distinguish this variant from standard plugs. Ensure compatibility with the corresponding receptacle counterpart. Confirm RoHS status details directly with the manufacturer or authorized distributor, as regulatory compliance documentation requires explicit verification for procurement records.

Selection Notes

Select this part for applications requiring a right-angle, dual-row board mount plug with 20 circuits. The 2.54 mm pitch suits standard density requirements. Verify that the 5 A current rating and 1 kV voltage rating meet circuit demands. Ensure the through-hole footprint matches the PCB design constraints for the specified tail length.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for mission-critical environments. The series emphasizes high density and reliability, often utilized in aerospace and defense sectors where strict adherence to MIL-DTL-55302 standards is mandatory for operational safety and performance consistency.

Replacement Considerations

The part number alias M55302/57B20X indicates potential cross-reference availability under the MIL-DTL-55302 specification. Verify exact mechanical dimensions and contact plating before substituting with generic MIL-spec equivalents to ensure interface compatibility.
