Needs validationmedium risk
A form-fit alternative with identical inductance and package, but requires review of its lower thermal current rating.
Best Alternatives to PRS6045-6R8MT
PRS6045-6R8MT is a 6.8µH shielded power inductor in a 6.0x6.0mm package, used in DC-DC converters. Finding a replacement requires matching inductance, current rating, DCR, and package size.
AI replacement insight
Electrical riskmedium
Key parameters like current rating and inductance vary across candidates, requiring circuit validation.
Package riskhigh
Several candidates have different footprints and are not drop-in replacements.
Sourcing risklow
Multiple functional alternatives from different manufacturers are available.
Can it be replaced directly?
Direct replacement for PRS6045-6R8MT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The closest alternative is FNR6045S6R8MT, which shares the same 6.8µH inductance and 6045 package. However, its lower thermal current rating (3.3A Irms) must be verified for the application's thermal performance.
Main risk
The main risks are thermal and electrical performance. Candidates may have lower current ratings, different inductance values, or larger packages, requiring board layout changes and circuit analysis.
