M55302/55-C20M

Overview

The M55302/55-C20M is a rectangular MIL-DTL-55302 connector from the AirBorn W Series, manufactured by Molex. It features a 20-position configuration with two rows of contacts. The component utilizes gold-plated copper alloy contacts and a polyphenylene sulfide (PPS) housing. Designed for board mount installation, it supports solder termination and operates within a temperature range of -65°C to +125°C. The connector provides an insulation resistance of 5 GOhms and maintains a standard 2.54 mm pitch.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for rugged reliability
• Utilizes gold-plated copper alloy contacts for stable signal transmission
• Constructed with high-performance PPS housing material for thermal stability

Applications

• Military avionics systems requiring certified interconnects
• Ruggedized electronic equipment operating in extreme temperatures
• Board-to-board connections in defense communication hardware

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Molex or authorized distributors before procurement. Confirm that the ordering suffix matches the required contact type and termination style. Ensure supply chain authenticity through verified channels to prevent counterfeit components in critical applications.

Selection Notes

Select this component when a 20-position MIL-DTL-55302 compliant connector is required for board-mounted applications. Consider the right-angle or straight orientation options available within the series based on spatial constraints. Verify compatibility with mating connectors regarding pin count and row configuration to ensure proper system integration.

Part Context

This part belongs to the AirBorn W Series, which offers a range of rectangular connectors designed for harsh environments. The series is characterized by its push-pull coupling mechanism and high-density contact arrangements. As a Molex brand product, it adheres to strict quality standards established during the transition from AirBorn to Molex.

Replacement Considerations

Direct replacements must match the MIL-DTL-55302 specification, 20-position count, and 2-row layout. Verify identical mounting style and termination method to ensure mechanical fit. Cross-reference with other manufacturers offering equivalent military-grade rectangular connectors if original availability is limited.
