FOJAN
A pin-compatible 30Ω 0.1W 0603 resistor with improved tolerance and temperature stability.
FRC0603J300 TS is a general-purpose 30Ω 5% 0.1W thick film resistor in a standard 0603 package. This page provides analysis of potential alternatives, including direct and parametric replacements.
Low for 30Ω parts. Medium for 27/33Ω parts, requires analysis.
All suggested alternatives are in the same 0603 package.
This is a very common resistor value and package size.
Direct replacement for FRC0603J300 TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Use a 30Ω, 0.1W, 0603 resistor with ±1% tolerance or better, like FOJAN's FRC0603F30R0TS or Fenghua's RS-03K30R0FT.
The main risk is substituting with a different resistance value (e.g., 27Ω or 33Ω), which requires circuit analysis.
