Very close alternative from the same series with a slightly different resistance value.
Best Alternatives to RT0603BRD0748K7L
The Yageo RT0603BRD0748K7L is a precision 48.7kΩ thin-film chip resistor in a 0603 package, valued for its tight ±0.1% tolerance and stable 25 ppm/°C TCR. Finding a replacement requires matching these key precision parameters.
AI replacement insight
Electrical riskhigh
Substituting with a general-purpose thick film part will degrade precision (tolerance, TCR).
Package risklow
All candidates share the same 0603 package, ensuring physical compatibility.
Can it be replaced directly?
No exact drop-in replacement is listed. The closest options are parametric alternatives from the same Yageo RT series which have slightly different resistance values but matching precision.
Best replacement path
Use another Yageo RT series thin-film resistor like RT0603BRD0747K5L for the closest performance, accepting a minor resistance shift.
Main risk
Degrading circuit precision by using a substitute with wider tolerance, higher TCR, or a different resistance value.
