WTB90PR7SY-0

Overview

The AirBorn WTB90PR7SY-0 is a rectangular MIL-DTL-55302 series connector designed for board mount applications. It features a right-angle plug configuration with 90 positions arranged in two rows. The contacts are male pins made of copper alloy with gold plating, suitable for 22 AWG wire. Rated for 5 A current and 1 kV voltage, it operates between -65°C and +125°C. The housing is constructed from Polyphenylene Sulfide (PPS), providing high insulation resistance of 5 GOhms at a 2.54 mm pitch.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for high reliability
• Right-angle through-hole termination for efficient board space utilization
• Gold-plated copper alloy pin contacts ensure stable signal transmission
• Polyphenylene Sulfide housing offers thermal stability and durability

Applications

• Military avionics systems requiring rugged interconnects
• High-density electronic equipment installations
• Board-to-board connections in harsh environments

Procurement Notes

Verify the specific suffix against official Molex/AirBorn documentation to confirm polarization and mounting variations. Ensure compatibility with mating receptacles within the same W Series family. Confirm RoHS compliance status via the manufacturer's certificate before integration into regulated assemblies.

Selection Notes

Select this model for applications demanding a 90-position right-angle interface. Verify that the 2.54 mm pitch aligns with PCB layout constraints. Consider the 5 A rating per contact when designing power distribution networks. Ensure the operating temperature range meets environmental requirements.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors known for high density and reliability. The series supports various configurations including straight and right-angle plugs. These connectors are widely used in defense and aerospace sectors where performance under stress is critical.

Replacement Considerations

Check for equivalents such as M55302/59A90Y. Verify dimensional and electrical compatibility before substitution.
