Substitute Part Grouping Explanation

Substitution eligibility for the CNY75C is determined by strict equivalence across the following critical parameters:

  • Voltage isolation rating: 5300Vrms
  • Current transfer ratio range: 160% to 320% @ 10mA
  • Output configuration: Transistor with Base
  • Maximum output voltage: 90V
  • Maximum output current per channel: 50mA
  • Package type: 6-DIP (0.300", 7.62mm)
  • Mounting method: Through Hole
  • Operating temperature range: -55°C ~ 100°C
  • Single channel configuration

The CNY75CX meets all specified parameters and qualifies as a parametric equivalent. Packaging variation (Tube vs. standard) does not affect electrical or mechanical compatibility.
