Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm contact count and orientation. Ensure compatibility with mating connectors regarding pin length and pitch specifications before integration into design projects.
Selection Notes
Select this component for applications requiring right-angle mounting with single-row connectivity. Confirm that the 2.54 mm pitch aligns with existing PCB layout requirements and that the through-hole termination method suits the manufacturing process.
Part Context
This component belongs to the AW140 series of pin headers, which are designed for general-purpose electronic interconnects. The series offers various configurations in terms of row count, orientation, and contact numbers to support diverse assembly needs.
Replacement Considerations
Compatible substitutes within the same AW140 series include AW140-EA-G21G (straight) or AW140-EG-G21C1 (straight). Verify physical dimensions and electrical ratings when considering alternative orientations or pin lengths.
