Headers, Male Pins Procurement Notes

Verify current lifecycle status directly with Molex/AirBorn as availability varies. Confirm specific ordering suffixes match required contact plating thickness and housing color variants. Request official RoHS compliance documentation prior to integration. Ensure mating connectors share identical MIL-DTL-55302 standards for mechanical compatibility.

Headers, Male Pins Selection Notes

Select this model for applications demanding right-angle PCB mounting with 50-pin density. Verify that the 2.54 mm pitch aligns with board layout constraints. Ensure the operating temperature range up to +125°C meets system thermal requirements. Confirm that the male pin configuration matches the female receptacle counterpart in the assembly.

Headers, Male Pins Part Context

This component belongs to the AirBorn W Series, a line of high-performance rectangular connectors designed for demanding environments. The series is characterized by push-pull locking mechanisms and robust construction. As a Molex product, it adheres to strict quality standards for defense and aerospace sectors, ensuring consistent performance under vibration and thermal stress.

Headers, Male Pins Replacement Considerations

Direct substitutes include other manufacturers' MIL-DTL-55302 compliant connectors with matching 50-position, 2-row, right-angle configurations. Cross-reference pinout diagrams and mating interface dimensions carefully. Verify that alternative parts support the same 2.54 mm pitch and solder termination method to ensure physical fit.
