RS-03K1802FT is a 18kΩ, 1% tolerance, 0.1W thick film resistor in a 0603 package. While no direct drop-in replacements are identified, several parametric alternatives with different resistance or tolerance values are available for consideration.

AI replacement insight

Electrical riskmedium

Resistance or tolerance mismatch requires circuit analysis.

Package risklow

All candidates share the same 0603 package.

Can it be replaced directly?

No, there are no direct drop-in replacements in this list. All candidates have different tolerance or resistance values requiring review.

Best replacement path

Find a 18kΩ, 1%, 0.1W, 0603 resistor. If unavailable, FRC0603J183 TS is an option if 5% tolerance is acceptable. Otherwise, review nearby 1% resistance values.

Main risk

Circuit malfunction due to incorrect resistance value or tolerance, affecting precision analog functions, voltage dividers, or feedback loops.
