Needs validationlow risk
Strong electrical upgrade with higher current and lower DCR. Package is very similar but requires layout check.
Best Alternatives to CYH74-33UH
Reviewing alternatives for the CYH74-33UH, a 33µH shielded power inductor in a 7.5x7.5mm SMD package. Key considerations for replacement are matching inductance while verifying current ratings and package footprint.
AI replacement insight
Package riskhigh
No candidates are a guaranteed fit; all require layout verification or redesign.
Electrical riskmedium
Target's saturation current is unknown, requiring careful analysis of the application's peak current.
Sourcing risklow
Multiple functional alternatives with better specs are available from different vendors.
Can it be replaced directly?
No drop-in replacement is confirmed. The closest option, PSPMAA0805-330M-ANP, requires layout verification.
Best replacement path
Upgrade to PSPMAA0805-330M-ANP for better electrical performance, but verify PCB layout compatibility due to a slightly larger package.
Main risk
The primary risk is mechanical incompatibility, as no candidates share the exact 7.5x7.5mm package. The target's unknown saturation current also adds electrical risk.
