Best Alternatives to LM393ADR

Package: SOP-8EVVOLinear - ComparatorsSupply Voltage (Single): 2V to 36VSupply Voltage (Split): ±1V to ±18VInput Offset Voltage (Max): 5mVInput Bias Current: 25nASupply Current: 0.4mA

LM393ADR replacements should be selected within the dual open-collector comparator family. Pinout evidence is missing, so all options need review.

AI replacement insight

Electrical riskmedium

Check supply range, output stage and pullups.

Package riskmedium

SOP-8 vs SOIC-8 naming may affect footprint.

Firmware risklow

Analog comparator; no firmware interface.

Sourcing riskmedium

Some lifecycle fields are blank.

Can it be replaced directly?

No verified pin-compatible replacement is proven from the provided fields.

Best replacement path

Prefer LM393 or LM293 family parts with verified SOP-8 pinout.

Main risk

Unverified pinout plus output-stage and supply-voltage limits.
