M55302/63B66H

Headers, Male Pins Overview

The M55302/63B66H is a rectangular MIL-DTL-55302 connector from the AirBorn W Series, manufactured by Molex. It features a 66-position configuration with two rows of female socket contacts. The unit utilizes a crimp termination method and is designed for PCB mounting in a straight orientation. Contact materials consist of copper alloy with gold plating to ensure reliable signal transmission. The housing is constructed from Polyphenylene Sulfide (PPS), providing thermal stability within an operating temperature range of -65°C to +125°C. Electrical specifications include a current rating of 5A and a voltage rating of 1000V.

Headers, Male Pins Feature Summary

Headers, Male Pins Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Molex or authorized distributors before procurement. Confirm that the crimp tooling requirements match the specified wire gauge for proper termination. Ensure the ordering suffix corresponds exactly to the required mounting style and contact configuration to avoid integration errors during assembly.

Headers, Male Pins Selection Notes

Select this component when a high-voltage, high-current MIL-spec solution is required for space-constrained applications. The 1000V rating distinguishes it from lower-voltage variants in the same series. Evaluate the straight PCB mount orientation against available panel space. Verify that the 66-position density aligns with the system's I/O requirements without necessitating multiple connectors.

Headers, Male Pins Part Context

This part belongs to the AirBorn W Series, a family of high-performance rectangular connectors known for durability in harsh environments. The M55302 designation indicates adherence to the MIL-DTL-55302 specification, ensuring interchangeability with other qualified manufacturers. As a Molex company product, AirBorn maintains rigorous quality controls for defense and aerospace supply chains.

Headers, Male Pins Replacement Considerations

Compatible substitutes must meet MIL-DTL-55302 specifications with identical 66-position, 2-row, female socket configurations. Verify that alternative sources offer matching 1000V ratings and PPS housing materials. Cross-reference pinout assignments and mounting hole dimensions to ensure mechanical compatibility with existing PCB layouts.
