Is there a pin-compatible replacement for MLZ1608N2R2LT000?

Sunltech SLM16082R2MIT shares the same 0603 package and pinout. However, its DC resistance is higher and its saturation current must be verified from the datasheet, so it is not a guaranteed drop-in replacement without engineering review.

What risks should I check before replacing MLZ1608N2R2LT000?

Key risks include package mismatch requiring PCB changes, higher DC Resistance (DCR) which can reduce efficiency, and different current ratings (both saturation and RMS) which can lead to performance issues or component failure. Always verify these parameters from the datasheet.

MLZ1608N2R2LT000 Alternatives, Datasheet & Cross Reference | TDK Electronics AG

Finding a substitute for the TDK MLZ1608N2R2LT000 2.2µH inductor involves balancing package size with electrical performance. While some alternatives offer a matching 0603 package, they may have different electrical characteristics. Other options provide superior current handling but require a larger PCB footprint.

AI replacement insight

Electrical riskmedium

Form-fit candidates may have higher DCR or unverified saturation current.

Package riskhigh

Many electrically superior alternatives are in larger packages, requiring a board redesign.

Can it be replaced directly?

No verified direct drop-in replacement has been identified. Sunltech SLM16082R2MIT is a form-fit candidate but has a higher DCR and requires saturation current verification.

Best replacement path

For existing PCBs, review SLM16082R2MIT after verifying its saturation current. For new designs, consider an upgrade to a larger package like the Sunlord WPN2016 series for better performance.

Main risk

The main risk is finding a part that matches both the 0603 package and the target's specific combination of low DCR and current rating.

Recommended alternatives

A form-fit candidate in a 0603 package, but has higher DCR and needs Isat verification.
