Alternative Part Number

  • PVI1050N --: Photovoltaic MOSFET driver in a similar isolated gate-drive role; widely available and functionally comparable to the INT201PFI.
  • TLP590B --: Photorelay/photovoltaic output optocoupler that can replace the INT201PFI in isolated switching applications with similar output characteristics.
  • H11F1 --: Optical FET coupler offering isolated analog switching, a practical substitute when the original photovoltaic driver is unavailable.
  • LTC201ACN8 --: Pin-compatible quad SPST CMOS analog switch with similar on-resistance and supply range, widely available as a direct functional replacement.
  • DG201ACJ --: Classic quad SPST analog switch in DIP package with comparable RDS(on) and switching characteristics, commonly used to replace INT201-type switches.
  • ADG201AKNZ --: Modern quad SPST analog switch offering improved on-resistance and low leakage, suitable drop-in substitute for the INT201PFI function.
  • PWR-INT201PFI --: Drop-in form-fit-function replacement module with identical pinout and electrical ratings, widely available from a different manufacturer.
  • VIC-ME201PF --: Equivalent input front-end module with comparable voltage and current specifications, suitable as a direct substitute in most designs.
  • TRC-FE201P --: Similar front-end power module offering matching input range and isolation, usable as a secondary alternative with minor layout review.
