M55302/55-A10S

Overview

The M55302/55-A10S is a rectangular MIL-DTL-55302 connector from the AirBorn W Series, manufactured by Molex. It functions as a receptacle with 10 positions arranged in two rows. The component utilizes solder cup termination for wire connections and features gold-plated copper alloy socket contacts. Designed for board mounting in a straight orientation, it operates within a temperature range of -65°C to +125°C. The housing is constructed from Polyphenylene Sulfide (PPS) with a 2.54 mm pitch.

Feature Summary

• Military-grade construction compliant with MIL-DTL-55302 specifications
• Gold-plated copper alloy socket contacts ensure reliable signal transmission
• Polyphenylene Sulfide (PPS) housing provides thermal stability

Applications

• Aviation avionics systems
• Military communication equipment
• Ruggedized electronic assemblies

Procurement Notes

Verify the manufacturer designation, as AirBorn is now part of Molex. Confirm that the specific suffix corresponds to the receptacle configuration with solder cup terminations. Ensure compatibility with mating plugs such as the M55302/55-A10M. Check RoHS compliance documentation if required for the specific project environment.

Selection Notes

Select this component when a MIL-Spec rectangular receptacle is required for harsh environments. It is suitable for applications demanding high reliability and specific contact arrangements. Consider the straight board mount style and solder cup termination method during PCB layout. Verify that the 10-position dual-row format meets the circuit density requirements.

Part Context

This part belongs to the AirBorn W Series, which offers various configurations including plugs and receptacles. The series is characterized by its push-pull coupling mechanism and robust performance in extreme conditions. Other variants include different pin counts and termination styles, all sharing the same fundamental MIL-DTL-55302 design principles.

Replacement Considerations

Direct substitutes may include other manufacturers producing MIL-DTL-55302 compatible connectors. Cross-referencing with standard MIL-C-55302 equivalents is possible but requires verification of dimensional and electrical parameters. Ensure mating compatibility with existing cable assemblies or panel interfaces.
