Is there a pin-compatible replacement for CYA0850-22UH?

No direct pin-compatible replacements were identified in this review. All suitable candidates have different package sizes (e.g., 1040, 1360) and require a new PCB layout.

What risks should I check before replacing CYA0850-22UH?

The primary risk is mechanical; all reviewed alternatives have different package sizes requiring a PCB redesign. Also, verify the saturation (Isat) and RMS (Irms) current ratings meet or exceed your application's needs.

CYA0850-22UH Alternatives, Datasheet & Cross Reference | SHOU HAN

Finding a substitute for the CYA0850-22UH 22µH inductor involves balancing electrical parameters with physical package size. While several functional alternatives exist, they require PCB layout changes due to different footprints.

AI replacement insight

Electrical risklow

Candidates meet or exceed key electrical specifications.

Package riskhigh

No candidates match the 0850 package, requiring a PCB redesign.

Sourcing risklow

Candidates are active parts from established manufacturers.

Can it be replaced directly?

No direct, drop-in replacement for CYA0850-22UH has been found. All viable alternatives require a change in the PCB layout due to package differences.

Best replacement path

Use a functional alternate like SMMS1360-220M for an upgrade, but plan for a PCB layout revision to accommodate the different package size.

Main risk

The main risk is the package mismatch, which makes these parts not drop-in compatible and requires a board spin.

Recommended alternatives

An electrical upgrade with higher current ratings, but requires a new layout for its larger 1360 package.
