Best Alternatives to LM393

Package: SOP-8PJSEMIAmplifiersNumber of Comparators: 2Supply Voltage (Single): 2V to 36VSupply Voltage (Dual): ±1V to ±18VInput Offset Voltage: 5mV (max)Input Bias Current: 250nA (max)

LM393 replacements should be checked as dual open-collector SOP-8 comparators. Package match alone is not enough without pinout evidence.

AI replacement insight

Electrical riskmedium

Some candidates relax bias, offset, or voltage.

Package riskmedium

SOP-8 strings match for most, but pinout is absent.

Firmware risklow

Analog comparator; no firmware dependency shown.

Sourcing riskmedium

Several lifecycle fields are dash only.

Can it be replaced directly?

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

Best replacement path

Start with LM393DR2G(XBLW), then verify pinout and limits.

Main risk

Pinout evidence is missing for all candidates.
