AI replacement insight

Electrical riskmedium

Polarity must be verified. Using a part with different voltage or current ratings is a high risk.

Package risklow

Several candidates share the same SOD-123FL package.

Can it be replaced directly?

Direct replacement for KPTVS6V0S1UR should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The most promising path is to use a part from the industry-standard SMF6.0A series, which matches all key parameters. SMF6.0A-MS is a good example.

Main risk

Polarity mismatch is the primary risk. The target is likely unidirectional, and substituting a bidirectional part (e.g., SMF6.0CA) without circuit analysis can lead to failure.
