Alternative Part Number

  • PC817 --: Industry-standard 4-pin DIP optocoupler with CTR and isolation ratings comparable to the K4N35, widely available and pin-compatible.
  • LTV-817 --: Direct functional equivalent optocoupler in DIP-4 package with similar current transfer ratio and isolation voltage, good second-source option.
  • EL817 --: Common 4-pin DIP phototransistor optocoupler matching the K4N35's typical CTR and 5kV isolation, suitable as a cost-effective replacement.
