AC0805FR-072KL
Yageo
Needs validationhigh risk
Parametrically similar but with a lower power rating (0.125W vs 0.25W). Requires engineering review.
Best Alternatives to AC0805FR-7W2KL
Yageo's AC0805FR-7W2KL is a 2kΩ, 1%, 0.25W AEC-Q200 qualified thick film resistor in an 0805 package. Finding a direct replacement requires matching these key parameters, especially the power rating.
AI replacement insight
Electrical riskhigh
Power rating mismatch is a critical failure point.
Package risklow
All candidates share the same 0805 package.
Sourcing riskmedium
Finding an exact 0.25W match is necessary.
Can it be replaced directly?
No direct, drop-in replacements were found in this batch. All candidates have a lower power rating (0.125W vs 0.25W), which poses a significant risk of failure.
Best replacement path
Search for 0805 resistors with 2kΩ, 1% tolerance, and a power rating of 0.25W or higher. The Yageo AC series (part number ending in 7W) or equivalents are good starting points.
Main risk
The primary risk is the lower power rating of all candidates, which can lead to overheating and component failure if the circuit dissipates more than 0.125W.

Questions & answers
The best alternative would be another 0805 chip resistor with 2kΩ resistance, ±1% tolerance, and a power rating of at least 0.25W. Yageo's AC0805FR-072KL is parametrically close but has only half the power rating, making it a risky downgrade.
