FOJAN
Matches resistance and package, but is a lower-precision thick film part with wider tolerance and higher TCR.
RT0805BRD074K3L is a high-precision 4.3kΩ thin-film chip resistor from Yageo in a standard 0805 package. It features a tight ±0.1% tolerance and a low TCR of 25 ppm/°C, making it ideal for precision analog circuits.
Using a part with incorrect resistance, tolerance, or TCR can cause circuit malfunction, especially in precision applications.
All candidates share the same 0805 package, ensuring physical compatibility on the PCB.
No direct, drop-in replacements were found. All identified candidates have parametric differences and require engineering review.
Search for 0805 thin-film resistors with 4.3kΩ resistance, ±0.1% tolerance, and a TCR of 25 ppm/°C from other manufacturers.
The primary risk is a deviation from required circuit precision due to differences in resistance, tolerance, or temperature stability.
