AI replacement insight

Electrical risklow

Resistance values differ by -6.7% to +5.2%. This is acceptable for many general-purpose applications but requires verification.

Package risklow

All candidates share the same 0402 package and 2-terminal footprint, ensuring physical compatibility.

Sourcing risklow

Candidates are from major manufacturers like Yageo, offering good availability.

Can it be replaced directly?

While no exact 2.1kΩ drop-in was found, several 0402 1% resistors are strong functional alternatives. AC0402FR-072K05L (2.05kΩ) and FRP0402F2001TS (2.0kΩ) are the closest matches and should be reviewed first.

Best replacement path

The strongest alternative is AC0402FR-072K05L from Yageo, which has a very close resistance of 2.05kΩ and is AEC-Q200 qualified.

Main risk

The primary risk is the slight deviation in resistance value. All presented alternatives are within a few percent of the 2.1kΩ target, which must be validated for the specific application.

Recommended alternatives

A very close alternative with 2.05kΩ resistance and AEC-Q200 qualification.

Questions & answers

The best alternative is likely AC0402FR-072K05L. It has a very close resistance of 2.05kΩ (a 2.4% difference), the same 1% tolerance and 0402 package, and is AEC-Q200 qualified.

Before replacing, check three main things: 1) Resistance: Ensure your circuit can tolerate a small deviation from 2.1kΩ. 2) Power Rating: Verify the replacement's power rating is at least 1/16W. 3) Technology: If considering the thin film option (RT0402BRD072K2L), confirm it's suitable for your application, as it may have different noise or pulse handling characteristics than the original thick film part.
