Substitute Part Grouping Explanation
Substitution is based strictly on equivalence in electrical and mechanical parameters provided for these AC/DC converter modules. Key parameters determining suitability include:
- Input voltage range
- Output voltage and current
- Power rating (Watts)
- Efficiency
- Application suitability (Medical)
- Features (Universal input)
- Mounting type and package/case
- Operating temperature range
- Agency approvals and safety standard number
- Line and load regulation
- Physical size and weight
- Environmental compliance (RoHS, REACH)
Only parts matching these criteria as presented are grouped as substitutes.
