A parametric alternative from the same TDK series with identical package, but slightly lower current rating and higher DCR.
Best Alternatives to MLP2012S4R7MT0S1
Finding a substitute for the TDK MLP2012S4R7MT0S1 4.7µH power inductor involves balancing electrical parameters like current rating and DCR with physical package compatibility. Several alternatives exist with varying trade-offs.
AI replacement insight
Package riskhigh
Many electrically superior alternatives have different footprints, requiring a PCB redesign.
Electrical riskmedium
Form-fit options may have lower current ratings or higher DCR. Inductance must be matched.
Sourcing risklow
4.7µH inductors in various packages are widely available from multiple manufacturers.
Can it be replaced directly?
No perfect drop-in replacement was found. The closest is TDK's MLP2012V4R7MT0S1, which has a slightly lower current rating (600mA vs 700mA) and higher DCR.
Best replacement path
For a near drop-in, consider TDK's MLP2012V4R7MT0S1, but verify the slightly lower current rating. For new designs, parts like XRIM252012S4R7MBCA offer better performance in a different package.
Main risk
The main risks are package mismatch requiring a board redesign, or electrical downgrades like lower current ratings or higher DCR, impacting performance and reliability.
