Is there a pin-compatible replacement for ME1502CM5G?

No pin-compatible replacement has been verified. All reviewed candidates have an active-high enable logic, differing from ME1502CM5G's active-low input, and require pinout confirmation from datasheets.

What risks should I check before replacing ME1502CM5G?

The main risk is the enable logic mismatch (active-low vs. active-high), which requires a circuit change. Pinout compatibility must also be verified from datasheets. Finally, confirm the current limit setting method matches your design needs.

ME1502CM5G Alternatives, Datasheet & Cross Reference | MICRONE

ME1502CM5G is an active-low, adjustable current-limit power switch in a SOT23-5 package. While no direct replacements are confirmed, several functional alternatives exist with similar electricals but require circuit changes for the enable logic.

AI replacement insight

Electrical riskhigh

Enable logic is inverted, which is a critical functional difference requiring a circuit change.

Package risklow

All candidates share the same SOT23-5 package, but pinout must be verified.

Can it be replaced directly?

No direct drop-in replacement is confirmed. All viable alternatives require circuit review, primarily for the inverted enable logic.

Best replacement path

Use ME1502AM5G from the same manufacturer and invert the enable signal in the circuit.

Main risk

Incompatible enable logic (active-high vs. active-low) will cause malfunction without circuit modification.

Recommended alternatives

A functional alternative from the same manufacturer, but with inverted enable logic requiring a circuit change.
