Is there a pin-compatible replacement for RT0805BRD0790K9L?

Yes, several 0805 package resistors are pin-compatible, but they have different electrical characteristics. For example, RC0805FR-0791KL has a similar resistance but lower precision.

What risks should I check before replacing RT0805BRD0790K9L?

Key risks include changes in circuit accuracy and stability. Verify the replacement's resistance value, tolerance (target is ±0.1%), and Temperature Coefficient of Resistance (TCR, target is 25 ppm/°C).

Electrical riskhigh

Target is a precision part; parametric downgrades can affect circuit performance.

Package risklow

0805 is a standard package, making physical replacement straightforward.

Can it be replaced directly?

No direct drop-in replacements were found. Alternatives require careful review of tolerance, TCR, and resistance value deviations.

Best replacement path

Find another thin-film resistor with 90.9kΩ resistance, ±0.1% tolerance, and ≤25 ppm/°C TCR in an 0805 package.

Main risk

The primary risk is loss of circuit precision due to using a resistor with wider tolerance, higher TCR, or different resistance.

Recommended alternatives

A 91kΩ resistor in the same 0805 package, but with lower precision (1% tolerance, ±100ppm TCR).
