WTA66PD9JTB

Overview

The WTA66PD9JTB is a rectangular MIL-DTL-55302 series connector manufactured by Molex / AirBorn. It features a straight plug configuration with 66 positions arranged in two rows. The component utilizes gold-plated copper alloy pin contacts and a Polyphenylene Sulfide (PPS) housing. Designed for board mount installation, it employs solder cup termination suitable for 22 AWG wire. Electrical ratings include a current capacity of 5 A and a voltage rating of 1 kV. The unit operates within a temperature range of -65 C to +125 C, offering an insulation resistance of 5 GOhms with a 2.54 mm pitch.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for rugged interconnect applications
• Features gold-plated copper alloy male pin contacts for reliable signal transmission
• Constructed with Polyphenylene Sulfide (PPS) housing for thermal stability
• Supports direct board mounting via solder cup termination method

Applications

• Military avionics systems requiring standardized rectangular connectors
• Ruggedized electronic equipment operating in extreme temperatures
• Board-to-board or cable-to-board interconnects in defense platforms
• High-density I/O interfaces in aerospace instrumentation

Procurement Notes

Verify the specific suffix JTB against official datasheets to confirm solder cup termination and straight orientation. Ensure compatibility with mating receptacles from the same W Series family. Confirm RoHS compliance status through manufacturer certificates if required by project specifications. Cross-reference the M55302/63A66H alias for legacy procurement channels. Validate environmental ratings against operational requirements before finalizing selection.

Selection Notes

Select this part when a high-density 66-position connection is required in a compact form factor. The straight plug design suits panel or board edge mounting scenarios. Verify that the 5 A current rating meets circuit demands. Consider the PPS material properties for high-temperature environments. Ensure the solder cup termination aligns with available assembly tools and processes.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding environments. The series offers various contact counts and termination options. The WTA prefix denotes a straight plug without mounting ears. This specific model provides a robust solution for applications needing MIL-spec reliability and high pin density in a standard 0.1-inch pitch format.

Replacement Considerations

The part number M55302/63A66H serves as a verified cross-reference alias for this component. When substituting, ensure the replacement matches the 66-position count, 2-row layout, and solder cup termination type. Verify that any alternative maintains the same MIL-DTL-55302 compliance and physical dimensions for proper fit.
