Yageo
Near-identical precision resistor from the same manufacturer, matching package, tolerance, and TCR.
The Yageo RT0402BRD079K09L is a precision 9.09 kΩ thin-film chip resistor in a 0402 package, featuring a tight ±0.1% tolerance and a low 25 ppm/°C TCR. It is ideal for applications requiring high stability and accuracy.
Using a part with different tolerance, TCR, or technology (Thick Film) can affect circuit accuracy and stability.
Many 0402 resistors are available, ensuring physical compatibility.
This is a common resistor value and package, with alternatives from multiple vendors.
Yes, Yageo's RT0402BRD079K1L is a near-perfect replacement, matching the package, power, tolerance, and TCR.
The best replacement is RT0402BRD079K1L, also from Yageo, offering nearly identical performance with a standard 9.1 kΩ resistance value.
The main risk when substituting is using a resistor with a wider tolerance (e.g., ±1%) or higher TCR (e.g., 100 ppm/°C), which can degrade circuit performance.
