Substitute Part Grouping Explanation
Substitute parts for the ISP825SM are identified based on strict equivalence across the following critical parameters:
- Dual-channel configuration (Number of Channels: 2)
- Isolation voltage rating (5300Vrms)
- Current transfer ratio range (600% to 7500% @ 1mA)
- Darlington output type
- Maximum output voltage (35V)
- Output current per channel (80mA)
- Surface mount packaging (8-SMD, Gull Wing)
- Operating temperature range (-30°C ~ 100°C)
- Compliance certifications (ROHS3, REACH Unaffected)
The ISP825XSM meets all these criteria and is classified as a parametric equivalent within the ISP825 series.
