WTB90SACSY

Overview

The AirBorn WTB90SACSY is a rectangular military specification connector belonging to the MIL-DTL-55302 WTB series. It features a straight receptacle configuration with 90 positions arranged in two rows. The component utilizes solder cup termination for board mounting and houses female socket contacts made of beryllium copper with gold plating. Constructed with a polyphenylene sulfide (PPS) housing, it supports a current rating of 5 A and a voltage rating of 333 V. The unit operates within a temperature range of -65°C to +125°C and maintains an insulation resistance of 5000 MOhms.

Feature Summary

• Military-grade construction compliant with MIL-DTL-55302 standards
• High-density 90-position layout in a compact two-row arrangement
• Gold-plated beryllium copper contacts for reliable signal transmission
• Thermally stable PPS housing suitable for extreme environments

Applications

• Avionics systems requiring high pin count interconnects
• Radar and electronic warfare equipment
• Ground-based military communication arrays
• Harsh environment industrial control panels

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure exact contact configuration and material specifications. Confirm that the ordering part number matches the required MIL-DTL-55302 compliance level. Check for any environmental sealing requirements or mating connector compatibility before finalizing procurement documentation.

Selection Notes

Select this model when a straight-mount receptacle with 90 positions is required for space-constrained military applications. Ensure the system design accommodates the 2.54 mm pitch and 5 A current capacity per contact. Verify that the operating temperature range aligns with the intended deployment environment and that the board mount style fits the mechanical assembly constraints.

Part Context

This component is part of the AirBorn WTB series, designed for rugged military and aerospace applications. The series offers various position counts and configurations while maintaining strict adherence to MIL-DTL-55302 performance standards. The WTB90 variant specifically addresses needs for higher density interconnects in standard rectangular form factors.

Replacement Considerations

Cross-reference with other manufacturers' MIL-DTL-55302 connectors only if dimensional and electrical parameters match exactly. Verify that substitute parts maintain the same contact type, plating, and housing material to ensure interchangeability without redesign.
