AI replacement insight
Package risklow
All viable candidates use the same SOT-23 package.
Electrical riskmedium
Some alternatives have slightly lower current ratings (200mA vs 215mA), which requires review.
Sourcing risklow
The BAV99 series is widely available from multiple major manufacturers.
Can it be replaced directly?
Yes, BAV99LT1G and BAV99,215 are strong candidates for direct, pin-compatible replacement, offering an upgrade in voltage performance.
Best replacement path
The BAV99LT1G from onsemi or BAV99,215 from Nexperia are the best replacement paths. They are pin-compatible upgrades with a higher voltage rating (100V vs. 75V) and matching current, providing a more robust solution.
Main risk
The main risk is selecting an alternative with an incorrect diode configuration (e.g., common cathode) or a lower current rating without verifying circuit requirements.
