Viking Tech
A thin-film resistor with the same package, resistance, and power, but a wider tolerance of ±1%.
Viking Tech's AR05BTCW2004 is a 2MΩ, 0.1% tolerance, 1/8W precision thin-film resistor in an 0805 package. Finding a direct drop-in replacement is challenging due to its high precision.
Tolerance, TCR, and technology are critical for precision circuits. Most alternatives are significant downgrades.
0805 is a standard package with many mechanically compatible options.
High-precision resistors (≤0.1%) can have limited availability and fewer sources.
No direct drop-in replacement with identical precision (±0.1%) was found. The closest alternatives have a wider tolerance of ±1%.
If ±1% tolerance is acceptable, use Viking Tech's ARG05FTC2004. If higher precision is mandatory, a redesign with a different available precision resistor may be needed.
Loss of precision due to wider tolerance and potential technology change from Thin Film to Thick Film.
