AI replacement insight

Electrical riskhigh

High if tolerance is relaxed from 1% to 5%.

Package risklow

Low for candidates in the same 1206 package.

Can it be replaced directly?

Yes, direct replacements with identical key parameters are available. CRCW12061R00FKEAHP is a strong candidate.

Best replacement path

Upgrade to a higher power-rated part like CRCW12061R00FKEAHP for improved thermal margin.

Main risk

The main risk is accidentally using a part with a wider resistance tolerance (e.g., 5% instead of 1%), which could compromise circuit performance.

Recommended alternatives

A 1Ω, 1% resistor in a 1206 package with a higher power rating (0.75W vs 0.5W).
