M55302/56B24

Overview

The M55302/56B24 is a rectangular MIL Spec connector from the AirBorn W Series, manufactured by Molex. It functions as a header with male pins, featuring 24 positions arranged in two rows. The component utilizes a solder termination style and is designed for free-hanging installation. Contacts are gold-plated copper alloy, rated for 22 AWG wire. The housing is constructed from Polyphenylene Sulfide (PPS). Electrical specifications include an insulation resistance of 5 GOhms and a current rating of 5 A. It operates within a temperature range of -65 C to +125 C with a 2.54 mm pitch.

Feature Summary

• Military-grade construction compliant with MIL-DTL-55302 standards
• Gold-plated contacts ensure reliable signal transmission
• Polyphenylene Sulfide housing provides thermal stability

Applications

• Avionics interconnect systems
• Ruggedized military electronics
• High-reliability industrial control panels

Procurement Notes

Verify the specific datasheet revision and RoHS compliance status directly with Molex/AirBorn before procurement. Confirm that the ordering suffix matches the required contact plating and housing material variants. Ensure compatibility with mating connectors within the same MIL-DTL-55302 series to guarantee proper interface alignment and electrical performance.

Selection Notes

Select this component when a 24-position male header is required for MIL-Spec environments. The 2.54 mm pitch suits standard wiring harnesses. Verify that the free-hanging mounting style aligns with the mechanical design constraints. Ensure the operating temperature range meets the environmental demands of the target application.

Part Context

This part belongs to the AirBorn W Series, a line of rectangular connectors designed for harsh environments. The M55302 designation indicates compliance with the MIL-DTL-55302 specification. AirBorn, now part of Molex, specializes in high-density interconnect solutions for defense and aerospace sectors, emphasizing durability and signal integrity.

Replacement Considerations

Compatible substitutes must match the 24-position count, 2-row configuration, and male pin contact type. Verify identical MIL-DTL-55302 compliance and 2.54 mm pitch. Cross-reference with other manufacturers producing equivalent MIL-spec headers to ensure mechanical and electrical interchangeability.
