A parametric alternative in the same 0603 package with a lower resistance of 43kΩ.
Best Alternatives to RT0603BRD0747K5L
RT0603BRD0747K5L is a precision 47.5kΩ thin film resistor from Yageo in a 0603 package, valued for its ±0.1% tolerance and 25 ppm/°C TCR. Finding a replacement requires matching these precision characteristics.
AI replacement insight
Electrical riskhigh
Substituting with a part that has worse tolerance or TCR can cause circuit failure.
Package risklow
Many 0603 resistors are available, so physical fit is not a major concern.
Can it be replaced directly?
No exact drop-in replacement was found. Alternatives exist with slightly different resistance values that require engineering validation.
Best replacement path
Look for thin film 0603 resistors with 0.1% tolerance, 25ppm/°C TCR, and resistance near 47.5kΩ.
Main risk
The main risk is substituting with a lower-precision thick film resistor, which can affect circuit accuracy and stability.
