A strong match with identical key specs, better temperature stability (TCR), and AEC-Q200 qualification.
Finding a substitute for the RC-02U1R00FT, a 1Ω ±1% 0402 chip resistor, involves matching its package, resistance, and power rating. The most critical factor to verify is the resistance tolerance, as many alternatives offer a wider ±5%.
Many alternatives have 5% tolerance vs. target's 1%. TCR may also vary.
All reviewed candidates use the same 0402 package, ensuring physical compatibility.
Direct replacement for RC-02U1R00FT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Yageo's AC0402FR-071RL is the strongest alternative, matching all key parameters while offering a better TCR and automotive qualification.
The main risk is using a substitute with a wider resistance tolerance (e.g., 5% instead of 1%), which can compromise circuit precision.
