Strong match on all key specs except TCR, which requires datasheet verification.
Finding a substitute for the FOJAN FRC0805F4990TS 499Ω 1% 0805 resistor involves matching key electrical parameters and package size. Several alternatives exist, from direct pin-compatible options to parametric alternatives.
Low if resistance and TCR match. Medium if using a parametric alternative.
All suggested candidates are in the same 0805 package.
This is a common resistor value available from multiple vendors.
Direct replacement for FRC0805F4990TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The most direct path is 0805W8F4990T5E, which matches primary specs. For higher precision, ARG05BTC5000 offers an upgrade.
The main risk is using a part with a different nominal resistance (e.g., 470Ω or 510Ω) in a precision circuit where 499Ω is critical.
