Note:   1. Recommended to use a high frequency, low ESR, electrolytic capacitor with at least 20% margin on voltage rating. 

2. A suppressor diode (TVS) is recommended to protect the downstream application in case of converter failure and should be rated for a minimum of 1.2 times the converter’s output voltage.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
