Best Alternatives to ARG03FTC1003
Finding a substitute for the Viking Tech ARG03FTC1003 100kΩ precision resistor involves matching its 0603 package, 0.1W power rating, and critically, its ±25ppm/°C TCR and thin film technology. Several alternatives are available, ranging from direct upgrades to more common, lower-spec parts.
AI replacement insight
Package risklow
All suggested alternatives are in the same 0603 package.
Electrical riskmedium
Some alternatives have higher TCR or use Thick Film technology, requiring review for precision applications.
Sourcing risklow
Multiple vendors offer suitable alternatives, improving supply chain resilience.
Can it be replaced directly?
Yes, several pin-compatible replacements exist for ARG03FTC1003. The best option is ARG03DTC1003, an upgrade from Viking Tech. Other alternatives may have different performance characteristics.
Best replacement path
