WTA20PD9JTA

Headers, Male Pins Overview

The WTA20PD9JTA is a rectangular MIL-DTL-55302 series board mount plug manufactured by Molex / AirBorn. It features a dual-row configuration with 20 positions and a 2.54 mm (0.100 inch) pitch. The connector utilizes pin contacts made of copper alloy with gold plating, terminated via through-hole soldering. Constructed with a polyphenylene sulfide (PPS) plastic body, it operates within a temperature range of -65°C to +125°C. Rated for 5 A current and 1 kV voltage, this straight-mount component includes a turning jackset mechanism without mounting ears.

Headers, Male Pins Procurement Notes

Verify the specific manufacturer part number against official Molex / AirBorn documentation to ensure compliance with MIL-DTL-55302 standards. Confirm that the turning jackset variant matches the mechanical requirements of the assembly. Check for RoHS certification status if environmental regulations apply to the final product integration. Ensure compatibility with corresponding receptacle components from the same W Series family.

Headers, Male Pins Selection Notes

Select this model when a dual-row, 20-position through-hole plug is required for MIL-Spec applications. The choice depends on the need for a turning jackset interface rather than standard hardware orientation. Consider the 2.54 mm pitch and PPS material properties for thermal management needs. Validate that the straight mounting angle fits the PCB layout constraints without interference from adjacent components or chassis structures.

Headers, Male Pins Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors designed for demanding applications. The WTA prefix indicates a two-row straight plug without mounting ears. This series is widely recognized in defense and aerospace sectors for its durability and consistent electrical performance across varying operational conditions.

Headers, Male Pins Replacement Considerations

Equivalent parts include M55302/63B20F. Verify dimensional tolerances and contact orientation before substitution. Ensure the replacement maintains the same turning jackset specification and through-hole termination style.
