Functionally similar with matched resistance but in a larger 0603 package.
Finding a substitute for the FRC0402F2402TS, a 24kΩ 1% 0402 resistor, involves choosing between functional alternatives with different packages or parametric alternatives with different resistance values. Careful engineering review is required for any substitution.
Candidates like RC0805FR-0724KL have a different footprint and are not physically compatible.
Candidates in the same package have resistance values that deviate from the target, requiring circuit analysis.
No direct, drop-in replacement was found in this analysis. All candidates require either a PCB layout change due to a different package size or have different resistance values that must be verified by an engineer.
If PCB layout can be modified, RC0805FR-0724KL is an electrical match. If the 0402 footprint is fixed, review parametric alternatives like 0402WGF2492TCE, but verify the resistance deviation is acceptable for the application.
The primary risks are package mismatch requiring PCB redesign, or resistance deviation impacting circuit performance.

No single 'best' alternative exists. If your design can accommodate a larger 0805 package, RC0805FR-0724KL is an electrical match. If you must use the 0402 package, 0402WGF2492TCE is a parametric alternative, but you must verify if its 24.9kΩ resistance is acceptable.
