Strong parametric match in the same 0603 package. Resistance, tolerance, power, and TCR are identical.
RS-03K7872FT is a general-purpose 78.7kΩ, 1%, 0.1W thick film resistor in a standard 0603 package. Several alternatives are available with matching or similar parameters.
All suggested alternatives use the same 0603 package.
Some alternatives have slightly different resistance values that require engineering review.
Direct replacement for RS-03K7872FT should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use FRC0603F7872TS for a direct parametric match. If unavailable, consider parametric alternatives like RC0603FR-0780K6L, but validate the resistance change.
The main risk is using a substitute with a different nominal resistance, which can alter circuit behavior.
