Is there a pin-compatible replacement for RT0402BRD075K11L?

Yes, several 0402 package resistors are pin-compatible. However, a true drop-in replacement must also match the critical electrical parameters like 5.11kΩ resistance, 0.1% tolerance, and 25ppm/°C TCR.

What risks should I check before replacing RT0402BRD075K11L?

Key risks include changes in resistance value (5.11kΩ vs 5.1kΩ), tolerance (e.g., 0.5% vs 0.1%), temperature coefficient (TCR), and technology (Thin Film vs Thick Film). These can impact the precision and stability of your circuit.

RT0402BRD075K11L Alternatives, Datasheet & Cross Reference | Yageo

The Yageo RT0402BRD075K11L is a high-precision 0402 thin-film resistor with 5.11kΩ resistance, 0.1% tolerance, and a 25ppm/°C TCR. Finding a substitute requires matching these tight specifications.

AI replacement insight

Electrical riskmedium

High precision specs (tolerance, TCR) are critical. Downgrades are risky.

Package risklow

The 0402 package is standardized, ensuring form/fit compatibility.

Can it be replaced directly?

No direct drop-in replacement was found with the exact same parameters from another major brand. However, several functional alternatives with slightly different resistance or relaxed parameters are available.

Best replacement path

Look for thin-film 0402 resistors with 0.1% tolerance and 25ppm/°C TCR. The exact 5.11kΩ value is less common than 5.1kΩ, which may be acceptable.

Main risk

The primary risk is substituting with a part that has a different nominal resistance, looser tolerance, or higher TCR, which can affect circuit accuracy.

Recommended alternatives

Yageo alternative with same package and precision (0.1%, 25ppm TCR), but slightly different 5.1kΩ resistance.
