AI replacement insight
Electrical risklow
Low for 1:1 matches, medium for parametric alternatives.
Package risklow
All suggested candidates use the same 2512 package.
Sourcing risklow
This is a common commodity resistor with many suppliers.
Can it be replaced directly?
Yes, direct pin-compatible replacements are available. The Yageo AC2512FK-072KL matches all critical parameters and is considered a strong alternative.
Best replacement path
The most straightforward replacement is a part with identical 2kΩ resistance, ±1% tolerance, and 1W power in a 2512 package, such as the Yageo AC2512FK-072KL.
Main risk
The main risk involves using substitutes with relaxed parameters, such as a wider tolerance (±5%) or a different resistance value (2.2kΩ), which could affect circuit performance.
