Is there a pin-compatible replacement for FRC1206F4R30TS?

Yes, candidates like HP06W2F470KT5E use the same 1206 package and 2-pin layout. However, you must verify the slight resistance difference (4.7Ω vs 4.3Ω) is acceptable for your design.

What risks should I check before replacing FRC1206F4R30TS?

Verify your circuit can tolerate a resistance of 4.7Ω instead of 4.3Ω. Also, ensure the physical dimensions of the 1206 package fit your layout. Avoid parts with lower power ratings or higher TCR.

FRC1206F4R30TS Alternatives, Datasheet & Cross Reference | FOJAN

Finding a substitute for the FRC1206F4R30TS, a 4.3Ω 1% 0.25W 1206 resistor, involves matching key parameters. Alternatives with higher power ratings offer increased reliability and are recommended.

AI replacement insight

Electrical risklow

Resistance is ~9% higher. Power rating of selected alternates is higher, which is a benefit.

Package risklow

All recommended alternatives are in the same 1206 package.

Sourcing risklow

The recommended alternatives are from major manufacturers (Vishay, UNI-ROYAL).

Can it be replaced directly?

No exact drop-in replacement is identified. However, several strong parametric alternatives exist with slightly different resistance (4.7Ω) and higher power ratings.

Best replacement path

Upgrade to a higher power resistor like CRCW12064R70FKEAHP or HP06W2F470KT5E, which also have a slightly higher resistance of 4.7Ω.

Main risk

The main risk is the slight resistance difference (4.7Ω vs 4.3Ω), which requires circuit analysis. Candidates with lower power ratings or worse TCR should be avoided.

Recommended alternatives

An AEC-Q200 qualified 1206 resistor with a much higher 0.75W power rating and similar 4.7Ω resistance.
