M55302/55-A10M

Overview

The M55302/55-A10M is a rectangular MIL-Spec connector from the AirBorn W Series, manufactured by Molex. It functions as a plug with 10 positions arranged in two rows. The component utilizes solder cup termination for wire connection and features gold-plated copper alloy contacts. Designed for free-hanging installation, it operates within a temperature range of -65°C to +125°C. The housing is constructed from Polyphenylene Sulfide (PPS), providing an insulation resistance of 5 GOhms. The contact pitch is 2.54 mm, and it supports a current rating of 5 A.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Gold-plated copper alloy contacts ensure stable signal transmission
• Polyphenylene Sulfide (PPS) housing offers thermal stability

Applications

• Military avionics systems requiring MIL-DTL-55302 compliance
• Ruggedized electronic equipment operating in extreme temperatures

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm exact termination style and mating compatibility. Ensure the procurement source provides valid traceability certificates required for MIL-Spec components. Cross-reference the part number with the latest AirBorn catalogs to confirm availability status and any potential obsolescence notices before finalizing orders.

Selection Notes

Select this model when a 10-position, dual-row plug is required for MIL-DTL-55302 applications. Choose based on the need for solder cup termination and free-hanging mounting styles. Consider the -65°C to +125°C operating range and PPS material properties for environmental suitability. Confirm that the 2.54 mm pitch aligns with the system's wiring density requirements.

Part Context

This component belongs to the AirBorn W Series, designed for high-density interconnect solutions. It adheres to the MIL-C-55302 standard, ensuring compatibility with other connectors in the same military specification family. The series is known for robust performance in demanding environments, offering various pin and socket configurations with standardized dimensions.

Replacement Considerations

Compatible substitutes include other MIL-DTL-55302 compliant plugs with identical 10-position, dual-row layouts. Verify that alternative parts match the 2.54 mm pitch, solder cup termination, and free-hanging form factor. Ensure mating interfaces are compatible with corresponding receptacles in the same series.
