Alternative Part Number

  • LTV-827 --: Dual-channel optocoupler in DIP-8 with similar CTR and isolation ratings, widely available and pin-compatible for most ILD256T applications.
  • PC817X2NSZ0F --: Dual optocoupler with comparable current transfer ratio and 5 kV isolation, suitable drop-in replacement for general-purpose signal isolation.
  • TLP281-2 --: Dual-channel phototransistor optocoupler with similar CTR range and isolation voltage, commonly used as an alternative to ILD256T.
  • PC817 --: Industry-standard single-channel optocoupler; use two devices or verify channel count, with comparable CTR and isolation performance.
  • TLP281-4 --: Multi-channel optocoupler offering similar CTR and isolation; suitable when additional channels or higher integration are acceptable.
