Strong pin-to-pin candidate with matching package, resistance, tolerance, power, and technology.
CR0402FF1003G is a general-purpose 100kΩ, 1% tolerance, 1/16W thick film resistor in a 0402 package. Finding a suitable replacement involves matching these key parameters and considering factors like technology and temperature coefficient.
High if tolerance or technology is mismatched without review.
All reviewed candidates use the same 0402 package.
This is a very common resistor value with many suppliers.
Yes, WR04X1003FTL is a direct replacement candidate for CR0402FF1003G, matching all critical specifications.
Direct replacement with a thick film 1% resistor like WR04X1003FTL is lowest risk. For precision needs, upgrade to a thin film part like RT0402BRE07100KL.
The main risk is using a part with a wider tolerance (e.g., 5% instead of 1%), which can affect circuit performance.
