WTAV40PCSY

Overview

The WTAV40PCSY is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It features a straight plug configuration with board mount installation and through-hole termination. The component provides 40 positions in a 2-row arrangement with a 2.54 mm pitch. Contacts are male pins made of copper alloy with gold plating. Rated for 1 kV voltage and 5 A current, it operates between -65°C and +125°C. The housing utilizes Polyphenylene Sulfide (PPS), ensuring an insulation resistance of 5 GOhms.

Feature Summary

• Compliant with MIL-DTL-55302 standards for military-grade reliability
• Utilizes gold-plated copper alloy contacts for corrosion resistance
• Constructed with PPS housing for thermal stability
• Supports high-voltage applications up to 1 kV

Applications

• Military avionics systems
• Defense communication equipment
• Spacecraft instrumentation panels

Procurement Notes

Verify the specific suffix against official Molex/AirBorn documentation to confirm contact type and termination style. Confirm RoHS compliance status via the manufacturer's certificate. Ensure mating connectors match the series specifications. Check for any obsolescence notices or lifecycle changes directly from the supplier before finalizing procurement plans.

Selection Notes

Select this model for applications requiring a straight, board-mount plug with 40 positions. Ensure the design accommodates through-hole soldering and a 2.54 mm pitch. Verify that the operating environment stays within the specified temperature range. Confirm compatibility with corresponding receptacles in the W Series family.

Part Context

This part belongs to the AirBorn W Series, which offers 0.100-inch rectangular interconnect solutions. The series is widely used in commercial aerospace, defense, and space sectors.
