Needs validationmedium risk
BAV99LT1G is close electrically but needs pinout and speed review.
Best Alternatives to BAV99,215
BAV99,215 is a Nexperia SOT23 dual series switching diode. Close alternates exist, but pinout and derating checks are required.
AI replacement insight
Electrical riskmedium
Some candidates are 200 mA or slower.
Package risklow
Kept items are SOT23 class.
Firmware risklow
Discrete diode, no firmware.
Sourcing riskmedium
PDF checks are pending.
Can it be replaced directly?
No verified drop-in replacement is confirmed from the provided data.
Best replacement path
Review BAV99LT1G first, then derated MMBD7000LT1G or MMBD4148SE.
Main risk
Pinout evidence and small-signal speed/current margins.
