Substitute Part Grouping Explanation

Substitution eligibility for the SFH617A-2G is determined by strict parametric equivalence across the following critical specifications:

  • Number of Channels: 1 (single-channel configuration)
  • Voltage - Isolation: 7.5Vpk (isolation rating)
  • Current Transfer Ratio range: 63% to 125% @ 10mA (optical coupling efficiency)
  • Output Type: Transistor (output stage configuration)
  • Voltage - Output (Max): 70V (maximum collector voltage)
  • Current - Output / Channel: 50mA (maximum output current)
  • Vce Saturation (Max): 400mV (saturation voltage)
  • Operating Temperature: -30°C ~ 100°C (thermal operating range)
  • Package / Case: 4-DIP (0.400", 10.16mm) (physical form factor)
  • Mounting Type: Through Hole (PCB assembly method)

The SFH617A-2XG meets all these parameters identically, establishing it as a parametric equivalent suitable for direct substitution in applications where the SFH617A-2G is specified.
