AI replacement insight
Electrical riskmedium
Resistance values differ by 2-8%, requiring circuit validation.
Package risklow
All candidates are in the same 0603 package.
Can it be replaced directly?
No direct, verified pin-to-pin replacement is currently identified. All reviewed candidates have a different resistance value, requiring circuit analysis before substitution.
Best replacement path
Use a standard E96 value of 4.53kΩ in a 0603 package with 1% tolerance and 1/10W power rating from a major manufacturer.
Main risk
The primary risk is the resistance value mismatch, which can alter circuit behavior, especially in precision applications like voltage dividers or filter circuits.

Questions & answers
The best alternatives are thick film 0603 resistors with resistance values very close to 4.53kΩ, like Yageo's RC0603FR-074K64L (4.64kΩ) or RC0603FR-074K42L (4.42kΩ). These require review as the resistance is not an exact match.
