Automotive-grade electrical upgrade (higher current, wider temp) in a larger 1210 package.
Best Alternatives to LQM18DN100M70L
Finding a replacement for the Murata LQM18DN100M70L 10µH inductor involves balancing package size with electrical performance. While some alternatives offer higher current ratings, they often come in larger packages requiring board changes.
AI replacement insight
Electrical riskhigh
Using a part with lower current rating can lead to saturation or failure.
Package riskmedium
Most electrically superior parts are in larger packages, requiring a board redesign.
Can it be replaced directly?
No direct, drop-in replacement with equivalent or better specifications was found. The closest form-fit match, CMP160808JE100MT, is a downgrade in current rating and requires careful review.
Best replacement path
For a drop-in replacement, review CMP160808JE100MT for its 0603 package, but be aware of its lower current rating. For better performance, functional alternates like WPN201610H100MT require a PCB layout change.
Main risk
The primary risk is either accepting a lower current rating with a same-package part or redesigning the PCB for a larger, higher-performance inductor.
