FOJAN
A higher precision (±1% tolerance) version from the same manufacturer, FOJAN.
FRC0805J683TS is a general-purpose 68kΩ 5% 0805 chip resistor. Numerous pin-compatible substitutes are available, including direct upgrades to higher precision from the same and other manufacturers.
Most candidates are upgrades. Risk is low for general use.
All suitable candidates share the same 0805 package.
Switching to thin film resistors requires review for sensitive circuits.
Direct replacement for FRC0805J683TS should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
The safest replacement is FRC0805F6802TS, which is a higher-precision version from the same manufacturer. For a cross-vendor option, RS-05K6802FT is a strong match.
The main risk involves changing resistor technology from thick film to thin film, which may affect performance in noise-sensitive or high-frequency applications.
