WTB90PR9SY

Overview

The WTB90PR9SY is a rectangular board connector from the AirBorn W Series, manufactured by Molex. It features 90 positions arranged in two rows with male pin contacts. The connector utilizes a 2.54 mm (0.1 inch) pitch and employs gold-plated copper alloy terminals for reliable signal transmission. Designed for through-hole termination, it mounts at a right angle to the printed circuit board. The housing is constructed from Polyphenylene Sulfide (PPS), providing durability in demanding environments. Electrical specifications include a current rating of 5 A and a voltage rating of 1 kV. It complies with MIL-DTL-55302 standards and operates within a temperature range of -65°C to +125°C.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for high-reliability applications
• Features gold-plated copper alloy contacts for enhanced conductivity and corrosion resistance
• Utilizes Polyphenylene Sulfide (PPS) housing material for thermal stability
• Supports right-angle board mounting with through-hole solder termination

Applications

• Aerospace control and display systems
• Military electronic warfare equipment
• Avionics interconnections
• High-density board-to-board connections

Procurement Notes

Verify the specific suffix codes against the official Molex/AirBorn datasheet to ensure correct contact plating, polarization, and mounting options. Confirm that the procurement source provides valid traceability documentation required for MIL-DTL-55302 components. Check for RoHS compliance status if applicable to the specific revision. Ensure the supplier is an authorized distributor to guarantee authenticity and prevent counterfeit parts in mission-critical deployments.

Selection Notes

Select this component when a right-angle, dual-row plug with 90 positions is required for MIL-DTL-55302 compliant designs. The 2.54 mm pitch suits standard density requirements. Consider the 5 A current rating and 1 kV voltage limit for electrical compatibility. Verify mating receptacle availability, such as the WTB90SAD9SY, to ensure system integration. Evaluate the operating temperature range against environmental conditions.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors known for high reliability in harsh environments. The series offers various row counts and position options, all adhering to strict military standards. The WTB90PR9SY specifically addresses needs for high-pin-count interconnects requiring robust mechanical locking and precise alignment in aerospace and defense platforms.

Replacement Considerations

M55302/57B90X is a documented alias for this component. Cross-reference with other W Series plugs for alternative position counts. Ensure mating receptacles match the specified polarization and guide set configurations.
