AI replacement insight

Package riskhigh

All viable candidates are larger than the target, requiring PCB layout verification.

Electrical risklow

Candidates have equal or higher voltage ratings, which is a safe substitution.

Can it be replaced directly?

No direct drop-in replacement has been identified. All potential alternatives require verification, primarily for package size.

Best replacement path

Consider AISHI SPZ1VM331G12O00RAXXX, which has a higher voltage rating but is physically larger. Careful verification of PCB space is essential.

Main risk

The main risk is mechanical interference, as potential alternatives are physically larger than the original 8x11mm package.

Recommended alternatives

Functional alternative with higher voltage but larger package. Requires mechanical fit verification.
