Substitute Part Grouping Explanation

Substitution of the ISO7230CDWG4 is determined by strict equivalence across the following critical parameters:

  • Isolation Voltage: 2500Vrms (mandatory match)
  • Channel Configuration: 3 channels, unidirectional (mandatory match)
  • Data Rate: 25Mbps (mandatory match)
  • Common Mode Transient Immunity: 25kV/µs (mandatory match)
  • Supply Voltage Range: 3.15V ~ 5.5V (mandatory match)
  • Package Type: 16-SOIC (0.295", 7.50mm Width) (mandatory match)
  • Technology: Capacitive Coupling (mandatory match)
  • Operating Temperature Range: -40°C ~ 125°C (mandatory match)

The ISO7230CDW qualifies as a direct substitute based on identical electrical specifications and package configuration. Packaging format differences (tube vs. alternative packaging) do not affect functional equivalence.
