Is there a pin-compatible replacement for WPN252012HR24MT?

TDK's VLS252012HBX-R24M-1 uses the same 2520 package and is likely pin-compatible, but it has a lower current rating and higher resistance. Full datasheet verification is required before use.

What risks should I check before replacing WPN252012HR24MT?

Key risks include package size mismatch requiring PCB layout changes, and electrical parameter differences like lower current ratings (Irms/Isat) or higher DC resistance (DCR), which can affect efficiency and reliability.

AI replacement insight

Package riskhigh

One alternative requires a larger 1210 footprint.

Electrical riskmedium

One alternative has lower current rating and higher DCR.

Can it be replaced directly?

No direct drop-in replacement has been identified. VLS252012HBX-R24M-1 is the closest in form-factor but has weaker electrical parameters, requiring careful circuit analysis.

Best replacement path

For a form-factor match, VLS252012HBX-R24M-1 is a candidate but requires review for its lower current rating. For an electrical upgrade, TMS322512ALM-R22MTAA is strong but requires a larger PCB footprint.

Main risk

The primary risk is either accepting a different package size (layout risk) or weaker electrical performance (circuit risk).

Recommended alternatives

A potential alternative in the same 2520 package, but with a slightly lower current rating and higher resistance.
