AI replacement insight

Electrical risklow

Key parameters match, but secondary specs like tolerance should be checked.

Package risklow

SOD-123 is a standard package, ensuring mechanical compatibility.

Sourcing risklow

This is a common part available from multiple vendors, reducing sourcing risk.

Can it be replaced directly?

Direct replacement for BZT52C15 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Use BZT52C15 from an alternate manufacturer like Diotec Semiconductor or GOODWORK, as they offer the same key specifications.

Main risk

Minor variations in Zener impedance, voltage tolerance, or reverse leakage current between different manufacturers.
