A precision upgrade with identical resistance and package, but different resistor technology.
FRC0603F3161TS is a general-purpose 3.16kΩ 1% 0.1W resistor in a 0603 package. While no exact replacement is listed, several close parametric alternatives and a high-precision upgrade path are available.
Resistance values are close (<5% deviation for top options). Verify circuit tolerance.
All candidates share the same 0603 package, ensuring form and fit compatibility.
Switching to Thin Film (RT0603BRD073K16L) may have cost and availability implications.
No exact drop-in replacement was found. However, several pin-compatible alternatives with minor parametric differences are available.
For precision, use RT0603BRD073K16L (Thin Film). For general use, FRC0603F3241TS is the closest parametric match.
The primary risks are resistance deviation in parametric alternatives and a technology change (Thick to Thin Film) for the precision upgrade.
