Substitute Part Grouping Explanation
Substitution logic is determined strictly by these core parameters for this category:
- Output voltage and current ratings (24V, 420mA)
- Power rating (10W)
- Input voltage range
- Package and mounting type (4-DIP Module, Through Hole)
- Product compliance (RoHS3, REACH, MSL)
- Approval/certification agency markings
- Efficiency
- Line and load regulation
Only substitute components with matching key parameters and relevant certifications, as specified above, are considered equivalent for direct replacement within the product category.
