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.

AI replacement insight

Electrical riskmedium

Using a part with different tolerance, TCR, or technology (Thick Film) can affect circuit accuracy and stability.

Package risklow

Many 0402 resistors are available, ensuring physical compatibility.

Sourcing risklow

This is a common resistor value and package, with alternatives from multiple vendors.

Can it be replaced directly?

Yes, Yageo's RT0402BRD079K1L is a near-perfect replacement, matching the package, power, tolerance, and TCR.

Best replacement path

The best replacement is RT0402BRD079K1L, also from Yageo, offering nearly identical performance with a standard 9.1 kΩ resistance value.

Main risk

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.
