Is there a pin-compatible replacement for FRC0402F8203TS?

No pin-compatible replacements with the exact 820kΩ resistance were identified in this review. Alternatives in the same 0402 package, such as FRC0402F7503TS, have a different resistance value and require engineering validation.

What risks should I check before replacing FRC0402F8203TS?

The main risks are package size and resistance value. If using an alternative like RC0603FR-07820KL, you must change the PCB layout. If using a 750kΩ part, you must analyze the impact of the ~8.5% resistance change on your circuit's performance.

FRC0402F8203TS Alternatives, Datasheet & Cross Reference | FOJAN

FRC0402F8203TS is a general-purpose 820kΩ, 1% tolerance, 1/16W thick film resistor in a standard 0402 package. Alternatives exist but may require design review for package size or resistance value changes.

AI replacement insight

Package riskhigh

Using a 0603 part requires a board redesign.

Electrical riskmedium

Using a 750kΩ resistor requires circuit analysis to ensure performance is not affected.

Can it be replaced directly?

No direct, drop-in replacement with identical key parameters was found in this review.

Best replacement path

Parametric alternative if resistance change is tolerable; functional alternative if PCB can be modified.

Main risk

Package mismatch or resistance value deviation.

Recommended alternatives

Functional alternative with same resistance and higher power rating in a larger 0603 package.

Questions & answers

No direct drop-in replacement was found. The best path depends on design flexibility. For the same resistance, RC0603FR-07820KL is an option but requires a larger 0603 footprint. For the same 0402 footprint, parts like FRC0402F7503TS are available but have a different resistance (750kΩ) that needs circuit validation.
