Strong parametric match in the same 0603 package. All key electrical values are identical.
Finding a substitute for the RS-03K2262FT, a 22.6kΩ 1% 0.1W 0603 resistor, involves matching key electrical parameters and package size. Several strong alternatives and parametric options are available.
For pin-compatible options, electrical risk is low. For parametric alternatives, resistance deviation must be checked.
All suggested candidates use the same 0603 package, minimizing layout and assembly risks.
The target and candidates are common resistor values from multiple manufacturers, indicating good availability.
Direct replacement for RS-03K2262FT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
FRC0603F2262TS from FOJAN is the strongest candidate, matching all key electrical parameters and package.
The main risk when substituting resistors is a mismatch in resistance, tolerance, or TCR, which can affect circuit performance.
