Procurement Notes

Verify the specific suffix 'M' indicates the tape and reel packaging configuration when ordering. Confirm that the manufacturer datasheet aligns with the required switching speed and isolation voltage ratings for your specific application environment. Ensure compatibility with standard surface mount assembly processes if utilizing the reel format.

Selection Notes

Select this component when high-speed digital isolation is required over slower alternatives like PC817. Consider the package type availability and ensure the operating temperature range meets environmental demands. Verify that the input current requirements fit within the driving circuit capabilities and that the output load matches the phototransistor's sink capacity.

Part Context

This part belongs to Everlight's family of high-speed optocouplers designed for modern digital applications. It serves as an upgrade to standard general-purpose optocouplers by offering faster response times. The series supports various isolation voltages and package styles to accommodate different PCB layout constraints and safety standards in industrial and consumer electronics.

Replacement Considerations

Direct replacements may include other high-speed optocouplers from manufacturers such as Vishay or Sharp with similar pinouts and electrical characteristics. Verify that substitute parts meet the same isolation voltage and current transfer ratio specifications. Check for equivalent package dimensions to ensure mechanical compatibility without redesigning the footprint.
