WTB10PR7J342

Overview

The WTB10PR7J342 is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It functions as a plug with 10 positions arranged in a 2-row configuration. The component utilizes through-hole termination and features gold-plated copper alloy pins. Designed for board mount installation at a right angle, it operates within a temperature range of -65°C to +125°C. Key electrical ratings include a current capacity of 5 A and a voltage rating of 1 kV. The housing is constructed from Polyphenylene Sulfide (PPS), providing an insulation resistance of 5 GOhms with a 2.54 mm pitch.

Feature Summary

• Complies with MIL-DTL-55302 standards for military-grade reliability
• Utilizes gold-plated contacts on a copper alloy substrate
• Features a robust Polyphenylene Sulfide (PPS) insulating housing

Applications

• Military avionics systems
• Ruggedized electronic equipment
• Defense communication hardware

Procurement Notes

Verify the specific suffix codes against official Molex/AirBorn documentation to ensure correct mating compatibility and environmental sealing specifications. Confirm RoHS compliance status and lead times directly with authorized distributors, as manufacturing schedules for MIL-spec components may vary based on production cycles and supply chain constraints.

Selection Notes

Select this part when a right-angle, board-mount plug is required for high-reliability applications. Ensure the mating receptacle matches the 2-row, 10-position layout and 2.54 mm pitch. Verify that the operating environment stays within the specified -65°C to +125°C range and that the 5 A current rating meets circuit requirements.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding environments. The series offers various contact counts and mounting styles while maintaining strict adherence to MIL-DTL-55302 performance criteria. The WTB10PR7J342 specifically addresses needs for compact, high-density interconnects in space-constrained military and industrial assemblies.

Replacement Considerations

Compatible substitutes include other WTB series plugs with identical position counts and pin configurations, such as WTB10PR7J variants. Cross-reference mating receptacles like WTBT10SAR7J to ensure mechanical and electrical interoperability without modifying existing board layouts.
