AI replacement insight
Electrical risklow
Key parameters match, but target TCR is unknown. Verify if application is temperature-sensitive.
Package risklow
All strong candidates use the same 0603 package, ensuring form and fit compatibility.
Sourcing risklow
This is a common resistor value and package available from multiple major manufacturers.
Can it be replaced directly?
Yes, several manufacturers including Yageo, FOJAN, and FH offer 91Ω 1% 0603 resistors that are strong pin-to-pin candidates for 0603WAF909JT5E, pending engineering review of TCR and power rating requirements.
Best replacement path
Use a 91Ω, 1%, 0.1W, 0603 thick film resistor like Yageo's RC0603FR-0791RL for a near-identical match, after verifying application sensitivity to TCR.
Main risk
The primary risk is ensuring the replacement's Temperature Coefficient of Resistance (TCR) is suitable, as this is unspecified for the original part.
