An automotive-grade 15nF, 50V, 10% X7R capacitor in the same 0402 package. Note the higher capacitance.
Finding a substitute for the Yageo CC0402KRX7R9BB123, a 12nF 50V 0402 MLCC, involves checking key parameters. Alternatives exist with similar voltage and package, but capacitance values often differ.
Capacitance differences require circuit analysis.
All candidates match the 0402 package.
No exact drop-in replacement was found. All candidates require review due to different capacitance values or tolerances.
Consider parts with slightly higher capacitance like GCM155R71H153KA55D (15nF) for decoupling, but always verify circuit requirements.
The primary risk is capacitance mismatch. Using a part with different capacitance can affect filter performance, timing, or circuit stability.
