WTB50PR9J

Overview

The AirBorn WTB50PR9J is a rectangular MIL-DTL-55302 series connector plug designed for board mount applications. It features a right-angle orientation with 50 positions arranged in two rows and a 2.54 mm pitch. The component utilizes gold-plated copper alloy pins and terminates via through-hole technology. Rated for 1 kV voltage and 5 A current, it operates within a temperature range of -65 °C to +125 °C. The housing is constructed from Polyphenylene Sulfide (PPS), providing an insulation resistance of 5 GOhms.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for high-reliability interconnects
• Features right-angle board mounting configuration for space-efficient PCB integration
• Utilizes gold-plated contacts on a copper alloy substrate for durable conductivity

Applications

• Military avionics systems requiring ruggedized interconnects
• Defense communication equipment interfaces
• High-density electronic assemblies demanding MIL-Spec reliability

Procurement Notes

Verify the specific position count and termination style against the target PCB footprint before ordering. Confirm that the right-angle orientation aligns with the mechanical enclosure constraints. Ensure the operating environment remains within the specified thermal limits to maintain performance integrity.

Selection Notes

Select this model when a 50-position, two-row connector is required for rigid board-to-board or cable connections. The right-angle design facilitates compact layouts where vertical clearance is limited. Verify compatibility with mating receptacles sharing the same MIL-DTL-55302 standard and contact arrangement.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors engineered for mission-critical environments. The series emphasizes durability and consistent electrical performance under harsh conditions. The WTB50PR9J specifically addresses needs for higher pin counts while maintaining the standard 2.54 mm spacing found across the family.

Replacement Considerations

The part number M55302/61B50 serves as a verified cross-reference for this component. When substituting, ensure the replacement matches the 50-position count, right-angle orientation, and through-hole termination method to maintain mechanical and electrical compatibility.
