A form-fit alternate with matching inductance and higher current rating, but wider tolerance and higher DCR.
Find alternatives for the Sunlord SDFL2012T470KTF, a 47µH, 0805 package multilayer chip inductor. This page provides analysis of potential substitutes, highlighting key parametric differences for your design.
Tolerance and DCR differences require circuit analysis.
All viable candidates use the same 0805 package.
Candidates are from major manufacturers like TDK.
No direct drop-in replacement has been identified. All suitable alternatives have parametric differences, such as wider tolerance or higher DC resistance, that require engineering review.
TDK's MLZ2012M series offers form-fit compatible options with higher current ratings, but requires accepting a wider inductance tolerance (±20%) and slightly higher DCR.
The primary risk is the substitute's wider inductance tolerance (±20% vs. the target's ±10%), which could impact the performance of sensitive filter or timing circuits.
