RZ7889-MS is a 5A, 18V bidirectional DC motor driver in a SOP-8 package from MSKSEMI, used in applications requiring robust motor control. This page reviews potential replacements and their compatibility.

AI replacement insight

Package risklow

SOP-8 package is standard, but pinout must be verified.

Electrical riskmedium

Candidates have matching or better specs, but control logic and protection behavior may differ.

Sourcing riskmedium

Check regional availability and lead times for all alternatives.

Can it be replaced directly?

Direct replacement for RZ7889-MS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Upgrade to RZ7899-MS for higher performance or consider CP2119CDTR(XBLW) as a cross-vendor option.

Main risk

The main risk is pinout incompatibility, even with matching packages. Electrical differences in control logic or protection thresholds could also require adjustments.
