FOJAN
Parametric alternative with same resistance and power, but wider ±5% tolerance.
RS-06K1203FT is a 120kΩ, 1% tolerance, 0.25W, 1206 thick film resistor. While no direct drop-in replacements are listed, several parametric alternatives with different resistance or tolerance values are available for consideration.
Resistance or tolerance differs in all candidates.
All candidates share the same 1206 package.
No direct, one-to-one replacement for RS-06K1203FT has been identified. All candidates require a review of parametric differences.
Evaluate parametric alternatives with slightly different resistance or tolerance.
Electrical performance deviation due to mismatched resistance or tolerance.
