WTB54PR9SY-3

Overview

The WTB54PR9SY-3 is a rectangular MIL-DTL-55302 qualified board mount plug from the AirBorn W Series. It features a dual-row configuration with 54 positions and male pin contacts. The connector utilizes through-hole termination for secure PCB attachment and operates at a right angle. Constructed with a polyphenylene sulfide (PPS) body and gold-plated copper alloy contacts, it supports a 2.54 mm pitch. Rated for 1 kV voltage and 5 A current, it functions within a temperature range of -65°C to +125°C.

Feature Summary

• MIL-DTL-55302 qualified military specification design
• Dual-row right-angle board mount plug configuration
• Gold-plated copper alloy pin contacts for reliable conductivity
• Polyphenylene sulfide housing material for thermal stability

Applications

• Military and defense electronic systems
• Aviation avionics interconnects
• Ruggedized industrial control boards
• High-reliability aerospace instrumentation

Procurement Notes

Verify the specific suffix '-3' against official Molex/AirBorn documentation to confirm exact contact tail length and mating compatibility. Ensure the procurement source provides valid traceability certificates required for MIL-DTL-55302 components. Confirm RoHS compliance status directly from the manufacturer's latest datasheet before integration into regulated supply chains.

Selection Notes

Select this component when a high-density, right-angle connection is required for MIL-Spec environments. The 54-position count and 2.54 mm pitch suit applications needing substantial signal routing in constrained spaces. Verify that the through-hole mounting style aligns with the target PCB fabrication capabilities and mechanical stress requirements.

Part Context

This part belongs to the AirBorn W Series, a family of rectangular connectors designed for harsh environments. It complements other W Series variants like WTB30PR9SY by offering higher density in a similar form factor. The series emphasizes durability and consistent performance across extreme temperature ranges typical of defense and aerospace sectors.

Replacement Considerations

Direct substitutes include equivalent MIL-DTL-55302 connectors from authorized manufacturers. Cross-reference part numbers such as M55302/57B54X for potential equivalents. Always validate dimensional drawings and contact plating specifications before substituting to ensure mechanical and electrical compatibility.
