High-precision thin film resistor with a different resistance value (1.15kΩ) and no automotive qualification.
YAGEO's AT0402BRD071K2L is a high-precision, automotive-grade 1.2kΩ resistor. Finding a suitable replacement requires a careful review of tolerance, temperature coefficient (TCR), and AEC-Q200 qualification to avoid compromising circuit performance and reliability.
Mismatches in tolerance, TCR, and resistance value can significantly alter circuit performance.
All candidates share the same 0402 package, ensuring physical compatibility.
Finding an exact match for this high-spec part may be challenging; compromises are likely needed.
No, there are no direct 1:1 replacements in this list. All candidates require engineering review due to differences in tolerance, TCR, resistance value, or automotive qualification.
For precision applications, alternatives must match the ±0.1% tolerance and ±25 ppm/°C TCR. For automotive use, AEC-Q200 is mandatory. No single candidate meets all criteria.
The primary risk is substituting a precision thin-film resistor with a lower-grade thick-film part or one with a different resistance value, impacting circuit accuracy and reliability.
