Is there a pin-compatible replacement for 0805W8F1691T5E?

Yes, several alternatives like FRC0805F1651TS and RC0805FR-071K6L are available in the same 0805 package, making them physically pin-compatible. However, their electrical parameters, specifically resistance, are not identical. You must verify if the resistance deviation is acceptable for your circuit.

What risks should I check before replacing 0805W8F1691T5E?

Before replacing 0805W8F1691T5E, you must check two main risks. First, verify that your circuit can tolerate the resistance difference from the 1.69kΩ target. Second, if considering a thin film alternative, confirm that its performance characteristics (e.g., pulse handling, noise) are suitable for your application.

Finding a substitute for the 0805W8F1691T5E, a 1.69kΩ 1% 0.125W resistor, involves considering parametric alternatives as it is a non-standard value. Options exist with slightly different resistance values in the same 0805 package, including both standard thick film and high-precision thin film parts.

AI replacement insight

Electrical riskmedium

Resistance deviation up to 5.3% requires circuit tolerance analysis.

Package risklow

All suggested alternatives use the same 0805 package, ensuring form-fit compatibility.

Electrical riskhigh

Switching from Thick to Thin Film technology can affect pulse/surge handling and noise characteristics.

Can it be replaced directly?

No direct, drop-in replacement with the exact 1.69kΩ resistance was found. However, several parametric alternatives with standard resistance values are available in the same 0805 package.

Best replacement path

For a direct technology match, FRC0805F1651TS offers the closest resistance at 1.65kΩ. For applications needing higher precision, RT0805BRD071K6L is an upgrade but requires verifying the impact of the technology change from thick to thin film.

Main risk

The primary risk is the resistance deviation between the 1.69kΩ target and the standard values of the alternatives. A secondary risk for some options is the change in resistor technology from thick film to thin film.
