Yageo
A strong alternative from Yageo with matching resistance, tolerance, power, TCR, and package.
Find and compare alternatives for the RS-03K1182FT, a 11.8kΩ 1% 0.1W 0603 thick film resistor. Top candidates include pin-compatible options and parametric alternatives from major manufacturers.
Key parameters are well-matched by top candidates. Parametric alternatives require circuit tolerance analysis.
All viable candidates use the standard 0603 package, ensuring form and fit compatibility.
Direct replacement for RS-03K1182FT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use RC0603FR-0711K8L from Yageo, which matches all key electrical parameters and package, pending datasheet review.
The primary risk is ensuring substitutes meet the application's power derating requirements, as some candidates only match the target's power rating without extra margin.
