A strong substitute with the same package and capacitance but a higher voltage rating.
Best Alternatives to CK1A471M-CRE77
Finding a substitute for the ST CK1A471M-CRE77, a 470µF 10V aluminum electrolytic capacitor in a 10x10.5mm SMD package, involves matching capacitance and physical size while ensuring the voltage rating is equal or higher.
AI replacement insight
Electrical risklow
Low if voltage is equal/higher and capacitance is matched. Medium if ESR/ripple current differs significantly.
Package riskhigh
High if a different package (e.g., through-hole or different SMD size) is chosen, as this requires a PCB redesign.
Sourcing risklow
This is a common capacitor value and package, so many alternatives should be available.
Can it be replaced directly?
Direct replacement for CK1A471M-CRE77 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Upgrade to a higher voltage part in the same package, such as LZ1V471M-CRG10 (35V), after verifying secondary parameters.
Main risk
The main risk is using a part with a different physical package, lower capacitance, or lower voltage without careful circuit analysis.
