Is there a pin-compatible replacement for VLS5045EX-220M?

No, a pin-compatible replacement for VLS5045EX-220M was not identified. All reviewed functional alternatives use a larger package size and will not fit the same PCB land pattern.

What risks should I check before replacing VLS5045EX-220M?

The primary risk is mechanical incompatibility; all alternatives are larger and require a board redesign. Also, check the DC Resistance (DCR), as a higher value can decrease power efficiency.

VLS5045EX-220M Alternatives, Datasheet & Cross Reference | TDK Electronics AG

Finding a substitute for the TDK VLS5045EX-220M 22µH inductor requires careful attention to its 5.0x5.0mm package. While many parts match electrically, they often have a larger footprint.

AI replacement insight

Package riskhigh

All candidates are larger than the target's 5.0x5.0mm package and require a new PCB layout.

Electrical risklow

Most candidates offer superior current ratings. Some have slightly higher DCR, which may impact efficiency.

Can it be replaced directly?

No, there is no direct, drop-in replacement for the VLS5045EX-220M among the candidates reviewed. All electrically suitable alternatives have a larger physical footprint.

Best replacement path
