UNI-ROYAL
Shares the 1206 package and 1kΩ resistance but is a thick film part with 1% tolerance and missing TCR data.
Finding a substitute for the Yageo RT1206BRD071KL, a precision 1kΩ thin film resistor, is challenging. While some parts match the 1206 package, they often lack the critical 0.1% tolerance and 25 ppm/°C TCR, requiring careful engineering review.
Most candidates have much worse tolerance and TCR.
One candidate has a smaller package, requiring a PCB redesign.
No direct, drop-in replacement was found. All candidates require careful review due to significant parametric or physical differences.
Search for another thin film resistor in a 1206 package with 1kΩ resistance, 0.1% tolerance, and a TCR of 25 ppm/°C or better.
The primary risk is replacing a precision thin film resistor with a general-purpose thick film part, which will degrade circuit accuracy and stability.

The best alternative depends on your design flexibility. For electrical performance, Yageo's RT0805BRD071KL is a match but requires a board redesign for its smaller 0805 package and has a lower power rating. If the package must be 1206, parts like RC1206FR-071KL are available but are a significant downgrade in precision.
