Substitute Part Grouping Explanation

Substitution for the PC817X2CSZ9F is determined by strict equivalence across the following critical parameters:

Single-channel configuration
5000Vrms minimum isolation voltage
Transistor output topology
50% minimum and 600% maximum current transfer ratio at 5mA
80V maximum output voltage
50mA maximum output current per channel
1.2V typical forward voltage
200mV maximum Vce saturation
Operating temperature range of -30°C to 100°C
4-DIP through-hole package format (0.300", 7.62mm)

Parts meeting all these parameters are classified as parametric equivalents. Parts with isolation voltage exceeding 5000Vrms or extended operating temperature ranges are classified as similar equivalents, as they provide enhanced performance while maintaining functional compatibility.
