AI replacement insight
Electrical riskmedium
Resistance value differs by up to 8%. Circuit performance must be re-evaluated.
Package risklow
All candidates use the same 0402 package, ensuring form and fit compatibility.
Sourcing risklow
Multiple vendors offer similar parts, providing a robust supply chain.
Can it be replaced directly?
No, there are no direct, drop-in replacements with the exact 21.5kΩ resistance value. All available alternatives are parametrically relaxed and require engineering validation.
Best replacement path
The closest value is RC-02K2102FT at 21kΩ (-2.3% deviation). All listed alternatives require engineering review to confirm circuit compatibility with the new resistance value.
Main risk
The primary risk is the deviation in resistance from the target's 21.5kΩ value, which can impact the performance of precision analog circuits like filters, voltage dividers, or feedback networks.
