Is there a pin-compatible replacement for GR442QR73D102KW01L?

No pin-compatible (1808 package) replacements with identical key parameters have been confirmed at this time. Available alternatives are in smaller packages and require a different PCB footprint.

What risks should I check before replacing GR442QR73D102KW01L?

The primary risk is physical incompatibility. Alternatives like CC1210KKX7RDBB102 are in smaller packages (e.g., 1210) and require a new PCB layout. Always verify the full datasheet for secondary parameters like ESR and ripple current.

AI replacement insight

Package riskhigh

No alternatives in the same 1808 package were found; PCB redesign is required.

Electrical risklow

Functional alternatives with identical key electrical ratings are available.

Can it be replaced directly?

No direct, drop-in replacement in the same 1808 package has been identified. All suitable alternatives require a change in the PCB footprint.

Best replacement path

Use a functional alternative like Yageo CC1210KKX7RDBB102 and adapt the PCB layout for the smaller 1210 package.

Main risk

Package mismatch is the main risk, preventing a drop-in replacement and requiring a board redesign.

Recommended alternatives
