Is there a pin-compatible replacement for SP2684K32CGR6LC?

While several candidates share the same radial package, none are confirmed as pin-compatible replacements due to significant capacitance differences. They are form-fit compatible, but not functionally identical without circuit review.

What risks should I check before replacing SP2684K32CGR6LC?

Verify three key areas: 1) The new capacitance value's effect on your circuit's filtering. 2) Ensure the replacement is an X2-class safety capacitor with at least a 320VAC rating. 3) Check physical dimensions for board compatibility.

Finding a substitute for the SP2684K32CGR6LC, a 0.68µF 320VAC X2 safety capacitor, requires careful matching of capacitance and safety ratings. While no direct drop-in replacements are identified, several parametric alternatives exist that require engineering review.

AI replacement insight

Electrical riskmedium

Capacitance mismatch in all candidates will alter filter characteristics.

Package risklow

Candidates share the same radial package type, but physical dimensions should be verified.

Can it be replaced directly?

No direct, drop-in replacement for SP2684K32CGR6LC has been identified. All viable alternatives require review due to significant differences in capacitance.

Best replacement path

Focus on candidates with an X2 class and ≥320VAC rating. Be prepared to validate circuit performance with a different capacitance value.

Main risk

The primary risk is altered EMI filtering performance due to capacitance mismatch. Using a part without an X2 safety rating is a critical safety hazard.

Recommended alternatives

A parametric alternative with higher capacitance but matching voltage, tolerance, and X2 safety class.
