A high-power alternative in the same 0805 package, but with a less stable temperature coefficient (TCR).
The Viking Tech ARG05FTC4701 is a 4.7kΩ, 1% tolerance, 0.125W thin film resistor in an 0805 package, valued for its tight ±25ppm/°C temperature coefficient. Finding a direct drop-in replacement requires careful matching of these key parameters.
TCR mismatch from ±25ppm/°C to ±100ppm/°C can affect circuit precision.
All viable candidates share the same 0805 package.
Multiple vendors produce similar parts, though with parametric trade-offs.
No direct drop-in replacement was found. All candidates with sufficient power rating have a weaker temperature coefficient (TCR) and different technology (thick film).
Parametric alternatives with higher power but weaker TCR.
Degradation in thermal stability due to higher TCR.
