Yageo
A strong alternative with identical resistance and power, and a tighter ±1% tolerance.
FRC1206J684 TS is a general-purpose 680kΩ, 5% tolerance, 0.25W thick film resistor in a 1206 package. Finding alternatives requires matching these key parameters.
Low if resistance, power, and package are matched.
Low if the 1206 package is maintained.
680kΩ 1206 resistors are widely available.
Yes, Yageo RC1206FR-07680KL is a direct replacement with a tighter tolerance.
Upgrade to a 1% tolerance part like Yageo RC1206FR-07680KL for better precision.
The primary risk when substituting is selecting a part with a different resistance value, which can alter circuit behavior.
