WTB50PR7J

Overview

The AirBorn WTB50PR7J is a rectangular MIL-DTL-55302 series connector designed for board mount applications. It features a right-angle configuration with through-hole termination and pin contacts. The unit provides 50 positions arranged in three rows with a 2.54 mm pitch. Constructed with a plastic body and fixed jackset, it includes mounting ears for secure installation. The connector supports a current rating of 5 A and operates within a temperature range of -65 °C to +125 °C.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for high reliability
• Features gold-plated copper alloy contacts for stable signal transmission
• Utilizes Polyphenylene Sulfide (PPS) housing material for thermal stability

Applications

• Military avionics systems requiring rugged interconnects
• Defense communication equipment
• High-density electronic assemblies

Procurement Notes

Verify the specific revision level and environmental certifications against the manufacturer's datasheet before procurement. Confirm that the three-row configuration matches the design requirements, as variations exist within the WTB series. Ensure compatibility with mating receptacles from the same series to maintain interface integrity.

Selection Notes

Select this component when a high-density 50-position connection is required in a constrained space due to its right-angle form factor. The three-row layout offers increased circuit density compared to dual-row alternatives. Verify that the 5 A current rating and 1 kV voltage withstand capability meet the system's electrical demands.

Part Context

This part belongs to the AirBorn W Series, a family of rectangular connectors known for durability in harsh environments. The WTB prefix indicates a PCB plug variant. The '7' suffix typically denotes specific contact arrangements or tail lengths defined by the manufacturer's internal coding standards for this series.

Replacement Considerations

M55302/61A50 is a confirmed government standard equivalent part number for this configuration.
