Finding a substitute for the Samsung CL31A105KB9LNNC 1µF 50V X5R 1206 capacitor is straightforward. Several alternatives offer upgraded performance with higher voltage ratings or wider operating temperature ranges (X7R/X8R dielectric), ensuring form, fit, and improved function.

AI replacement insight

Electrical risklow

Change from X5R to X7R/X8R is an upgrade but may alter DC bias characteristics.

Package risklow

All suggested alternatives are in the same 1206 package.

Can it be replaced directly?

Yes, direct replacements are available. Look for 1µF, 50V (or higher), 1206 package capacitors. Parts with X7R dielectric are common upgrades.

Best replacement path

Upgrade to a 100V X7R capacitor like Samsung's CL31B105KCHVPNE for increased voltage margin and a wider temperature range.

Main risk

The primary risk is minimal, involving a change in dielectric from X5R to the superior X7R or X8R. This improves temperature stability but may slightly alter DC bias characteristics.
