WTAV56PD9SYL

Overview

The WTAV56PD9SYL is a rectangular MIL-DTL-55302 board mount plug manufactured by Molex / AirBorn. It features 56 positions arranged in two rows with a 2.54 mm pitch. The connector utilizes pin (male) contacts made of copper alloy with gold plating, terminated via through-hole soldering. Rated for 5 A current and 1 kV voltage, 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

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Features gold-plated copper alloy pin contacts for stable signal transmission
• Constructed with Polyphenylene Sulfide housing for thermal stability
• Designed for vertical straight through-hole board mounting

Applications

• Military avionics systems
• Ruggedized communication equipment
• Defense electronics assemblies

Procurement Notes

Verify the specific suffix SYL against official datasheets to confirm terminal length and guide set configuration. Confirm RoHS compliance status directly with the manufacturer or authorized distributor, as environmental declarations may vary by production batch. Ensure mating receptacles are selected from the compatible W Series lineup to guarantee proper mechanical engagement and electrical continuity.

Selection Notes

Select this component when a high-density 56-position connection is required in space-constrained military applications. The 2.54 mm pitch allows for compact circuit board layouts while maintaining robust contact integrity. Verify that the through-hole termination method aligns with the target PCB manufacturing capabilities and that the operating temperature range meets the environmental demands of the deployment site.

Part Context

This part belongs to the AirBorn W Series, a family of rectangular connectors designed for harsh environments. The series offers various contact counts and termination options, standardized around the MIL-DTL-55302 specification. The WTAV56PD9SYL represents a specific configuration within this lineage, balancing high pin count with reliable performance standards.

Replacement Considerations

Cross-reference with M55302/63B56X for equivalent military specification compliance. Verify mechanical dimensions and contact alignment before substituting to ensure compatibility with existing chassis and mating hardware.
