Needs validationmedium risk
A 0.1% tolerance, 25ppm/°C TCR thin film resistor in a 0603 package, but with 49.9kΩ resistance instead of 47kΩ.
Best Alternatives to RT0603BRD0747KL
Yageo's RT0603BRD0747KL is a high-precision 47kΩ thin-film resistor in an 0603 package, featuring a tight ±0.1% tolerance and a low 25 ppm/°C TCR. Finding a direct drop-in replacement requires matching these precise specifications.
AI replacement insight
Electrical riskhigh
Target is a precision part; any deviation in resistance, tolerance, or TCR can impact performance.
Package risklow
The 0603 package is standard, but alternatives must match the footprint.
Can it be replaced directly?
No direct, verified pin-to-pin replacements have been identified. Several candidates have different resistance values or lower precision, requiring engineering review.
Best replacement path
The best path is to find another thin-film 0603 resistor with 47kΩ resistance, ±0.1% tolerance, and a TCR of 25 ppm/°C or better.
Main risk
The primary risk is a loss of circuit accuracy due to mismatched resistance, tolerance, or temperature stability (TCR).
