Is there a pin-compatible replacement for RC0402FR-0784K5L?

Yes, several pin-compatible 0402 package resistors are available. However, there are no exact resistance matches in this list. All suggested alternatives require review as their resistance values (e.g., 82kΩ, 86.6kΩ) differ from the target's 84.5kΩ.

What risks should I check before replacing RC0402FR-0784K5L?

The primary risk is the change in resistance. Verify how a different resistance value (from -4.6% to +7.6%) affects your circuit's timing, biasing, or feedback loops. While other parameters like power, package, and tolerance match, the resistance deviation must be validated.

AI replacement insight

Electrical riskmedium

Resistance value differs, which may affect circuit timing, gain, or bias points.

Package risklow

All candidates use the same 0402 package, ensuring form and fit compatibility.

Can it be replaced directly?

No direct drop-in replacement with the exact 84.5kΩ resistance is listed. All candidates are parametric alternatives requiring engineering review.

Best replacement path

Use a parametric alternative with the closest resistance value, such as 0402WGF8662TCE (86.6kΩ) or RC0402FR-0782KL (82kΩ), after circuit analysis.

Main risk

Circuit performance deviation due to resistance mismatch.

Recommended alternatives

Cross-vendor alternative with a slightly higher resistance. Package and other key ratings match.
