Sourcing riskmedium

kept parts are indexed but need FAE review

Can it be replaced directly?

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

Best replacement path

Review SLM6300 first only for 5V-input designs; use DS6521AFD33 only as a lower-current redesign option.

Main risk

Pinout is unverified and several candidates change input range, current, or topology.
