SY8204FCC is close electrically but is a 4A downgrade from SY8205FCC.
SY8205FCC is a 5A 30V synchronous buck regulator in SO8E. Listed alternatives need FAE review because pinout is unverified.
closest candidate is 4A vs 5A
SO8E matches but pinout missing
analog buck, no protocol shown
some lifecycle fields are blank
Direct replacement for SY8205FCC should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
SY8204FCC is the closest candidate if 4A operation is acceptable.
Current rating is lower and pinout is not verified.
