Viking Tech
A higher precision (±0.1% tolerance) upgrade from the same manufacturer and series.
ARG05FTC1003 is a precision 100kΩ 0.125W 0805 thin film resistor from Viking Tech, featuring ±1% tolerance and a low ±25ppm/°C TCR for stable applications. Finding a substitute requires matching this temperature performance.
TCR mismatch is the primary risk, affecting performance in temperature-sensitive circuits.
All candidates share the same 0805 package, ensuring physical compatibility.
Precision thin film resistors can have longer lead times than general-purpose thick film parts.
Yes, ARG05BTC1003 is a direct upgrade with tighter tolerance. Other parts are functional but have higher TCR and require review.
The best path is finding another thin film resistor with a TCR of ±25ppm/°C or better, like ARG05BTC1003, which is an upgrade.
The main risk is substituting with a common thick film resistor, which will have a much higher Temperature Coefficient of Resistance (TCR).
