Yageo
Same resistance and package, but this is a lower-precision thick film resistor that requires engineering review.
Finding a substitute for the Yageo RT0402BRD0718K7L precision resistor involves balancing performance and availability. This 18.7 kΩ, 0.1% tolerance, 25 ppm/°C thin film resistor has alternatives that require design review.
Using a part with different resistance or lower precision can affect circuit accuracy and stability.
All suggested alternatives share the same 0402 package, minimizing physical layout issues.
No direct, drop-in replacement with identical key parameters was identified. All candidates require engineering review.
Check circuit tolerance for a parametrically similar part with slightly different resistance, like RT0402BRD0718K2L (18.2kΩ).
The primary risk is performance degradation from using a resistor with a different resistance value, lower precision (tolerance), or lower stability (TCR).

The best alternative depends on your circuit's tolerance. Parts from the same Yageo RT0402 series like RT0402BRD0718K2L (18.2kΩ) are parametrically similar but have different resistance values. If precision is not critical, a thick film resistor like RC0402FR-0718K7L offers the same resistance but with lower performance.
