WTA36PD9J

Overview

The WTA36PD9J is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It is a straight plug designed for board mount applications with through-hole termination. The component features 36 positions arranged in two rows with a 2.54 mm pitch. Contacts are male pins made of copper alloy with gold plating. The housing is constructed from Polyphenylene Sulfide (PPS). Electrical ratings include a current capacity of 5 A and a voltage rating of 1 kV. Insulation resistance is specified at 5 GOhms. The operating temperature range spans from -65 C to +125 C.

Feature Summary

• Complies with MIL-DTL-55302 military specifications for high-reliability interconnects.
• Utilizes a Polyphenylene Sulfide (PPS) housing for thermal stability and durability.
• Features gold-plated copper alloy contacts to ensure consistent signal integrity.
• Designed for vertical board mounting with through-hole solder termination.

Applications

• Military avionics systems requiring ruggedized interconnects
• Ground-based defense communication equipment
• Aerospace electronic control units
• Harsh environment industrial instrumentation

Procurement Notes

Verify the specific contact orientation and hardware configuration against the official datasheet before ordering. Confirm that the straight plug form factor matches the PCB layout requirements. Ensure compatibility with mating receptacles within the same W Series family. Check for any specific environmental sealing or mounting ear options if required by the design. Validate RoHS compliance status for the intended market regulations.

Selection Notes

Select this part when a 36-position, two-row male connector is needed for direct PCB attachment. The 2.54 mm pitch suits standard density layouts. Consider the 5 A current rating for power distribution needs. The PPS material offers advantages over thermoplastics in high-temperature soldering processes. Verify that the straight orientation fits the enclosure constraints without requiring angled adapters.

Part Context

This component belongs to the AirBorn W Series, a line of rectangular connectors known for meeting stringent military standards. The series offers various position counts and row configurations. The WTA designation specifically indicates a straight plug without mounting ears. This series is widely used in applications demanding high reliability and performance under extreme conditions.

Replacement Considerations

M55302/56B36 is a potential cross-reference based on MIL-DTL-55302 equivalence. Verify pinout and mechanical dimensions before substitution. Contact the manufacturer for approved alternate part numbers ensuring identical electrical and environmental ratings.
