WTB50PR9SY-3

Overview

The AirBorn WTB50PR9SY-3 is a rectangular MIL-DTL-55302 qualified plug connector from the W Series. It features 50 positions arranged in a dual-row configuration with male pin contacts. Designed for board mount installation, it utilizes a right-angle through-hole termination style. The connector employs gold-plated copper alloy contacts and a polyphenylene sulfide (PPS) housing. Key electrical specifications include a 1 kV voltage rating, 5 A current rating, and 5 GOhms insulation resistance. It operates within a temperature range of -65°C to +125°C with a 2.54 mm pitch.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for rugged reliability
• Features right-angle through-hole mounting for efficient PCB space utilization
• Utilizes gold-plated contacts on a PPS housing for corrosion resistance

Applications

• Military avionics systems requiring MIL-DTL-55302 compliance
• Ruggedized electronic equipment operating in extreme temperatures
• High-density circuit interconnections in defense applications

Procurement Notes

Verify the specific suffix '-3' against official Molex/AirBorn documentation to confirm polarization and guide set configurations. Ensure compatibility with mating receptacles sharing the same MIL-DTL-55302 series designation. Confirm RoHS status and material declarations directly with the manufacturer or authorized distributors prior to procurement.

Selection Notes

Select this component when a high-density, right-angle board mount solution is required for MIL-DTL-55302 environments. The 50-position count and 2.54 mm pitch suit applications needing substantial I/O in constrained spaces. Verify that the 5 A current rating and 1 kV voltage withstand requirements align with the system's electrical loads and isolation needs.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for harsh environments. The WTB prefix indicates a board mount plug configuration. As an AirBorn product now under Molex, it maintains strict adherence to military standards while offering modern manufacturing capabilities for critical interconnect solutions.

Replacement Considerations

Compatible substitutes must match the MIL-DTL-55302 specification, 50-position count, and right-angle through-hole form factor. Cross-reference exact polarization codes and guide set requirements to ensure mechanical interchangeability with existing mating hardware.
