AI replacement insight

Package riskhigh

Target is a 4-pin MC-146; all candidates are 2-pin in different packages, requiring a new PCB layout.

Electrical risklow

Candidates with matching electrical parameters are available, but require careful selection.

Can it be replaced directly?

No, a direct pin-compatible replacement has not been identified. All reviewed alternatives require a PCB layout change due to different packages and pin counts (2-pin vs. 4-pin).

Best replacement path

For new designs, X1A0001410005 offers superior electrical performance. For existing boards, no direct drop-in has been identified; redesign is likely required.

Main risk

The primary risk is mechanical incompatibility. Using any of the proposed alternatives requires a board redesign.

Recommended alternatives

Electrical upgrade with tighter tolerance and lower ESR, but requires board redesign.
