WTA66PD9JTB

Headers, Male Pins Overview

The WTA66PD9JTB is a rectangular MIL-DTL-55302 series connector manufactured by AirBorn, a Molex company. It features a straight plug configuration with 66 positions arranged in two rows. The component utilizes pin (male) contacts made of copper alloy with gold plating, designed for solder cup termination. 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), offering an insulation resistance of 5 GOhms. With a 2.54 mm pitch and support for 22 AWG wire, this board mount plug provides high-density interconnect capabilities for demanding applications.

Headers, Male Pins Procurement Notes

Verify the specific contact orientation and hardware configuration against the official AirBorn datasheet before ordering. Confirm that the solder cup termination method aligns with your assembly process capabilities. Ensure environmental ratings meet operational requirements. Cross-reference the manufacturer part number with any legacy designations to avoid procurement errors. Validate compatibility with mating receptacles in the same series.

Headers, Male Pins Selection Notes

Select this model when a 66-position straight plug is required for MIL-DTL-55302 compliance. Choose based on the need for solder cup termination rather than through-hole or surface mount options. Consider the 2.54 mm pitch constraint for board layout density. Evaluate the PPS material properties against chemical exposure risks in the intended environment. Confirm that the 5 A current rating suffices for the circuit load.

Headers, Male Pins Part Context

This component belongs to the AirBorn W Series, a family of rectangular connectors designed for high-density applications. The series offers various position counts and contact types to suit different interface needs. As a Molex company product, it adheres to strict quality standards for defense and aerospace markets. The WTA designation specifically indicates a two-row straight plug without mounting ears, distinguishing it from other variants in the lineup.

Headers, Male Pins Replacement Considerations

The part number alias M55302/63A66H may serve as a direct substitute in existing designs. Verify dimensional tolerances and contact geometry compatibility before swapping components. Ensure that any replacement maintains the same MIL-DTL-55302 certification level. Check for availability of mating receptacles that match the new part's specifications.
