Is there a pin-compatible replacement for FRC1206F1R30TS?

FRC1206F1R20TS from the same FOJAN series is a potential pin-compatible match, sharing the same package, power, and tolerance. However, its resistance is 1.2Ω, which requires engineering validation for your circuit.

What risks should I check before replacing FRC1206F1R30TS?

The main risk is the change in resistance. Candidates have values like 1.2Ω or 1.43Ω instead of 1.3Ω. This deviation, while small, can affect circuit performance in precision applications like feedback networks or current sensing.

AI replacement insight

Electrical risklow

Resistance differs by ~10%; may be critical in precision circuits.

Package risklow

All suggested alternatives share the same 1206 package.

Can it be replaced directly?

No exact drop-in replacement is identified. The closest options require review due to a slight resistance difference (e.g., 1.2Ω vs 1.3Ω).

Best replacement path

Cross-vendor upgrade to KOA Speer SR73 series for better power and TCR, accepting a minor resistance change.

Main risk

Slight resistance deviation may impact circuit accuracy.

Recommended alternatives

Same series alternate with a slightly lower resistance (1.2Ω vs 1.3Ω).
