An automotive-grade upgrade with a higher 50V rating, suitable for high-reliability applications.
Best Alternatives to CL21B475KPFNNNE
The Samsung CL21B475KPFNNNE is a general-purpose 4.7µF 10V 0805 ceramic capacitor. Several pin-compatible upgrades with higher voltage ratings and improved reliability are available from manufacturers like TDK and Chinocera.
AI replacement insight
Electrical risklow
Most alternatives offer higher voltage, which is a low-risk upgrade. Capacitance and tolerance match.
Package risklow
All viable candidates use the same standard 0805 package.
Sourcing risklow
This is a very common capacitor value and package, with many manufacturers.
Can it be replaced directly?
Yes, direct pin-compatible replacements are readily available. Most are upgrades with higher voltage ratings (e.g., 25V or 50V), which is a safe and often desirable improvement.
Best replacement path
Upgrade to a higher voltage part like TDK's automotive-grade CGA4J1X7R1H475KT0Y0N for maximum reliability, or a general-purpose upgrade like Chinocera's HGC0805R7475K500NSLJ.
Main risk
The primary risk is substituting with a capacitor that has a different dielectric type, such as X5R instead of X7R. This can reduce the operating temperature range and affect performance stability.
