Application Scenarios & Design Considerations

Optocouplers

Alternative Part Number

  • H11A1 --: Standard phototransistor optocoupler with similar CTR and isolation ratings, widely available and pin-compatible in many designs.
  • PC817 --: Very common general-purpose phototransistor optocoupler with comparable isolation voltage and current transfer ratio, easy second source.
  • 4N35 --: Classic 6-pin phototransistor optocoupler offering similar functionality and isolation, suitable as a functional replacement with pinout check.
  • 4N25 --: Standard 6-pin DIP optocoupler with phototransistor output, similar isolation voltage and current transfer ratio, common drop-in substitute.
