DFE252010P-2R2M=P2
Murata Electronics
Needs validationmedium risk
A 2.2µH inductor in a 2520 package with matching temperature range, but lower current ratings and higher DCR.
Best Alternatives to DFE252012P-2R2M=P2
The Murata DFE252012P-2R2M=P2 is a 2.2µH shielded power inductor for high-density power applications. Finding a direct replacement requires careful matching of current ratings and DC resistance.
AI replacement insight
Electrical riskhigh
Candidates have lower current ratings and higher DCR, risking saturation or overheating.
Package risklow
Candidates share the same 2520 footprint.
Can it be replaced directly?
No direct drop-in replacement was found; all candidates have weaker electrical parameters requiring engineering review.
Best replacement path
Parametric alternatives with relaxed current/DCR ratings.
Main risk
Reduced current handling capability and lower efficiency due to higher DCR.
