WTAX66SAD9SYL

Overview

The WTAX66SAD9SYL is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It features a straight, board-mount receptacle configuration with 66 positions arranged in two rows. The component utilizes through-hole termination for socket contacts made of copper alloy with gold plating. Designed for operation between -65°C and +125°C, it supports a current rating of 5 A and a voltage rating of 1 kV. The housing is constructed from Polyphenylene Sulfide (PPS), offering an insulation resistance of 5 GOhms at a 2.54 mm pitch.

Feature Summary

• Military-grade construction compliant with MIL-DTL-55302 specifications
• Gold-plated copper alloy socket contacts for reliable signal transmission
• Polyphenylene Sulfide (PPS) housing material for thermal stability

Applications

• Board-to-board interconnects in military avionics systems
• Ruggedized electronic enclosures requiring high-density connections
• Defense communication equipment interfaces

Procurement Notes

Verify the specific suffix codes against official Molex / AirBorn documentation to ensure correct contact type and orientation. Confirm RoHS compliance status directly with the manufacturer as regulatory requirements may vary by production batch. Cross-reference the MIL-DTL-55302 designation to validate performance standards before integration into critical circuits.

Selection Notes

Select this part for applications requiring a straight, dual-row receptacle with through-hole mounting. Ensure the mating plug corresponds to the W Series specifications. Verify that the 2.54 mm pitch and 66-position count align with the PCB layout constraints. Consider the operating temperature range when evaluating environmental exposure scenarios.

Part Context

This component belongs to the AirBorn W Series, a line of high-reliability rectangular connectors designed for demanding environments. The series offers various configurations including plugs and receptacles with different row counts and termination styles. The WTAX66SAD9SYL specifically addresses needs for high-density, board-mounted female connections in ruggedized electronics.

Replacement Considerations

The part number alias M55302/64-B66X serves as a confirmed substitute identifier. Verify mechanical dimensions and electrical ratings match exactly before substitution. Consult official datasheets for both part numbers to confirm compatibility with existing mating hardware.
