Is there a pin-compatible replacement for WPN201610U1R0MT?

Several parts like TDK's TFM201610ALMA1R0MTAA and Murata's DFE201610E-1R0M=P2 share the same 2016 package. However, they are not perfect drop-in replacements due to differences in DC resistance, requiring engineering review.

What risks should I check before replacing WPN201610U1R0MT?

Key risks include: 1) Higher DC Resistance (DCR) causing increased power loss and heat. 2) Lower RMS current rating (Irms) leading to overheating. 3) Physical package differences (e.g., height) that may cause assembly issues.

Finding a replacement for the Sunlord WPN201610U1R0MT 1.0µH inductor involves matching its 2016 package, 2.1A RMS current, and 50mΩ DCR. Several alternatives exist with similar form-factors but may have trade-offs in DCR or current ratings.

AI replacement insight

Electrical riskmedium

DCR and current ratings vary across candidates, requiring careful selection.

Package risklow

Several candidates match the 2016 footprint, but height and non-matching packages pose a risk.

Sourcing risklow

Multiple vendors offer viable alternatives.

Can it be replaced directly?

No perfect drop-in replacement is identified. Candidates like TDK's TFM201610ALMA1R0MTAA match the package but have higher DC resistance, which will increase power loss and requires review.

Best replacement path

For a near drop-in, consider Murata's DFE201610E or TDK's TFM201610ALMA series, but verify the slightly higher DCR. For new designs, functional alternates offer better electrical performance in different packages.

Main risk

The main risk is increased power loss and heat due to higher DC Resistance (DCR) in some alternatives, or physical incompatibility from different package sizes.

Recommended alternatives

Strong form-fit alternative with higher current ratings but slightly increased DC resistance.
