Functional alternative with tighter tolerance (±5%) but different capacitance (1.0µF) that needs review.
Finding a substitute for the Samsung CL21B684KBFVPNE 0.68µF capacitor often means considering common 1.0µF alternatives. While form-factor compatible, this capacitance difference requires careful engineering review.
Capacitance mismatch requires circuit analysis.
Candidates share the same 0805 package.
No direct, drop-in replacement with matching 0.68µF capacitance was found. Common alternatives have a higher capacitance of 1.0µF and require validation.
Use a 1.0µF capacitor with an equal or higher voltage rating, like TCC0805X7R105K101FT (100V), and validate its impact on the circuit.
The primary risk is the ~47% increase in capacitance, which can alter circuit behavior, especially in timing, filtering, or feedback loop applications.
