Is there a pin-compatible replacement for ANR4030T6R8M?

No, a pin-compatible replacement for ANR4030T6R8M was not found in this analysis. All functional alternatives have a larger physical footprint, which necessitates changes to the printed circuit board layout.

What risks should I check before replacing ANR4030T6R8M?

The main risk is the package mismatch; you must verify that your PCB layout can accommodate a larger component. While the electrical parameters (current, DCR) of the alternatives are upgrades, you should still confirm they are suitable for your specific application's power-delivery network.

ANR4030T6R8M Alternatives, Datasheet & Cross Reference | APV Technology (Shenzhen) Co., Ltd

ANR4030T6R8M is a compact 6.8µH power inductor in a 4.0x4.0mm package. While no direct drop-in replacements have been identified, several functional alternatives exist with superior current ratings but require a larger footprint and PCB redesign.

AI replacement insight

Package riskhigh

No candidates match the 4.0x4.0mm package. PCB redesign is mandatory.

Electrical risklow

All candidates offer superior current handling and lower or similar DCR, which is generally a safe upgrade.

Can it be replaced directly?

No direct, drop-in replacement for ANR4030T6R8M was found. All potential substitutes have a larger physical package and require a PCB layout modification.

Best replacement path

If board space allows for a 5.4x5.2mm footprint, FAUL0530-6R8MT is the best functional alternative, offering higher current ratings and AEC-Q200 qualification.

Main risk

The primary risk is physical incompatibility. All identified alternatives are larger than the target's 4.0x4.0mm package, making them unsuitable as drop-in replacements.

Recommended alternatives

A functional alternative with higher current ratings and AEC-Q200 qualification, but in a larger package.
