Substitute Part Grouping Explanation
The substitute part list is determined strictly by matching the main device's parameters as per allowed ranges for DC DC converter modules within the same category. The critical criteria are:
- Number of outputs
- Input voltage range
- Output voltage range
- Maximum output current
- Power rating
- Module type (Isolated vs. Non-Isolated)
- Application suitability
- Mounting type and package
- Operating temperature range
- Environmental and compliance certifications
The alternative ATS030A0X3-SRHZ is included as a substitute based on these criteria.
