TMI3113 is a 3A, 1MHz synchronous step-down converter in a TSOT23-6 package. Find functional alternatives and potential pin-compatible replacements, but review package and electrical differences before implementation.

AI replacement insight

Package riskhigh

Most alternatives are in different packages requiring a PCB redesign.

Electrical riskmedium

Some candidates have different switching frequencies, affecting external components.

Firmware risklow

These are not programmable devices, so no firmware risk is involved.

Can it be replaced directly?

Direct replacement for TMI3113 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

FP6373AS6CTR offers the most direct replacement path due to identical electrical specs and a similar package, pending pinout verification.

Main risk

The primary risk is physical incompatibility; most alternatives are in different packages requiring a PCB redesign. Even for similar packages, pinout must be confirmed.
