Best Alternatives to RT0603BRD073K48L
Yageo's RT0603BRD073K48L is a precision 0603 thin-film chip resistor with 3.48 kΩ resistance, 0.1% tolerance, and a 25 ppm/°C TCR. This page reviews potential substitutes and their compatibility.
AI replacement insight
Electrical riskhigh
Using a part with weaker tolerance or TCR can cause circuit malfunction, especially in analog, measurement, or filtering applications.
Package risklow
All candidates share the same 0603 package, ensuring physical compatibility.
Can it be replaced directly?
Direct replacement for RT0603BRD073K48L should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Use another Yageo RT-series resistor like RT0603BRD073K6L for the closest match in precision and stability.
Main risk
Substituting with a general-purpose resistor (thick film, ≥1% tolerance) will degrade circuit precision and stability.
