Viking Tech AR05BTCW0100 is a strong alternative with identical key electrical parameters and package.
The Viking Tech ARG05BTC0100 is a high-precision 10Ω 0.1% thin-film resistor in an 0805 package. Finding a suitable replacement requires matching its tight tolerance and low temperature coefficient (TCR).
High risk if tolerance or TCR are not matched, impacting circuit accuracy.
Low risk as 0805 is a standard SMT package.
Direct replacement for ARG05BTC0100 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The best replacement path is to select another 0805 thin-film resistor with 10Ω resistance, ≤0.1% tolerance, and ≤±25ppm/°C TCR, such as the Viking AR05BTCW0100.
The primary risk is substituting with a lower-precision resistor (e.g., thick film, >0.1% tolerance), which can compromise the performance of sensitive analog circuits.
