Reviewing substitutes for the Viking Tech ARG02BTC4701, a 4.7kΩ 0.1% 25ppm/°C thin film resistor in an 0402 package. This analysis identifies pin-compatible alternatives, upgrades, and parametric variants from Yageo and Viking Tech.
AI replacement insight
Electrical riskmedium
Some candidates have weaker TCR or lower voltage ratings. Mismatched resistance is also a risk with parametric alternatives.
Package risklow
All reviewed candidates use the same 0402 package, ensuring physical compatibility.
Sourcing risklow
Alternatives from major manufacturers like Yageo are widely available, potentially improving supply chain resilience.
Can it be replaced directly?
Direct replacement for ARG02BTC4701 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The most straightforward replacement is Yageo RT0402BRD074K7L, which is a pin-to-pin match. For enhanced reliability, consider the automotive-grade AT0402BRD074K7L.
Main risk
The main risk is using a substitute with a weaker Temperature Coefficient (TCR) or lower voltage rating, which can compromise precision and safety.
