ARG05BTC5000 is the closest catalog match with same value, size, power and tighter tolerance.
ARG05FTC5000 is a 500Ω precision 0805 resistor. The closest catalog substitute is the tighter-tolerance ARG05BTC5000, pending FAE review.
TCR or value shifts can affect precision nodes.
Kept candidates are 0805 with 2 pins.
Passive resistor; no firmware.
Stock and regional source not provided.
Direct replacement for ARG05FTC5000 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Review ARG05BTC5000 first; it matches value, package, power and TCR with tighter tolerance.
TCR, resistance shift, and power derating in the actual circuit.
