A parametrically similar alternative with a 1.15kΩ resistance value. Lacks automotive qualification.
Finding a substitute for the AEC-Q200 qualified AC0603FR-071K2L resistor requires careful review of tolerance, TCR, and automotive rating. While some parts are mechanically compatible, key electrical and qualification differences exist.
Using a part with weaker tolerance or TCR can affect circuit performance.
Using a non-AEC-Q200 part in a qualified design can cause compliance failure.
0603 is a standard package with many mechanically compatible options.
No direct, verified drop-in replacement has been identified. All candidates have parametric or qualification differences requiring engineering review.
Search for an AEC-Q200 qualified 0603 resistor with 1.2kΩ resistance, ±1% tolerance, and TCR of ±100ppm/°C or better.
The primary risk is using a non-AEC-Q200 part in an automotive application, or a part with weaker tolerance, impacting circuit precision and reliability.
