Substitute Part Grouping Explanation

Substitute parts for the PS2533L-1-K-A are identified as parametric equivalents within the NEPOC series. The substitution criteria are based on the following key parameters that must remain constant:

  • Single-channel configuration (Number of Channels: 1)
  • Isolation voltage rating (5000Vrms)
  • Darlington output type
  • Current transfer ratio range (1500% to 6500% @ 1mA)
  • Maximum output voltage (350V)
  • Output current per channel (150mA)
  • Vce saturation (1V maximum)
  • Operating temperature range (-55°C ~ 100°C)
  • Surface-mount packaging (4-SMD, Gull Wing)
  • Rise/Fall time specifications (100µs, 100µs)

The identified substitutes differ only in packaging configuration (Tube packaging versus the original K-A designation) while maintaining identical electrical performance and mechanical compatibility.
