M55302/56B30

Overview

The M55302/56B30 is a rectangular MIL-DTL-55302 connector from the AirBorn W Series, manufactured by Molex. It features 30 positions arranged in two rows with a 2.54 mm pitch. The component utilizes gold-plated copper alloy sockets and terminates via solder cup connections. Designed for free-hanging installation, it operates within a temperature range of -65°C to +125°C and maintains an insulation resistance of 5 GOhms.

Feature Summary

• Compliant with MIL-DTL-55302 military specifications for high-reliability interconnects
• Constructed with Polyphenylene Sulfide (PPS) housing for thermal stability
• Features gold-plated contacts to ensure consistent signal integrity

Applications

• Military avionics systems requiring ruggedized connectors
• Defense communication equipment interfaces
• Harsh environment electronic assemblies

Procurement Notes

Verify current manufacturing status directly with Molex or AirBorn, as lifecycle information may be unavailable through standard distributors. Confirm that the specific suffix matches the required contact configuration and termination style for your application before finalizing procurement orders.

Selection Notes

Select this part when a 30-position, two-row connector with solder cup termination is required. Ensure compatibility with mating plugs from the same W Series family. Verify that the free-hanging mounting style aligns with the chassis or panel design constraints of the target assembly.

Part Context

This component belongs to the AirBorn W Series, which provides standardized rectangular connectors under the MIL-DTL-55302 specification. The series offers various position counts and termination options to support diverse military and aerospace interconnect needs while maintaining strict dimensional and performance standards.

Replacement Considerations

Direct substitutes must adhere to the MIL-DTL-55302 standard with identical 30-position, two-row geometry. Cross-reference mating parts to ensure pin-to-pin compatibility. Verify that alternative sources maintain the same PPS material and gold plating specifications.
