Engineering Selection Recommendations

For Direct Replacement (Same Electrical Performance): Select C0805C682K2RAC7800 (KEMET) or CC0805KKX7RABB682 (YAGEO) when maintaining 200V X7R specifications. Both parts are active products with higher inventory availability than the original part. The KEMET variant offers reduced thickness (0.035" vs 0.051"), which may provide PCB layout advantages.

For Upgraded Voltage Margin: Select C0805C682KARAC7800 (KEMET) or CC0805KKX7RYBB682 (YAGEO) for 250V X7R performance. These parts maintain X7R temperature stability while providing 50V additional voltage headroom. Both manufacturers are active product lines with substantial inventory.

For High-Voltage Applications: Select C0805C682KBRAC7800 (KEMET) when 630V rating is required. This part maintains X7R characteristics with significantly elevated voltage capability, though thickness increases to 0.055" (1.40mm).

For Superior Temperature Stability: Select C0805C682JAGAC7800 (KEMET) or C2012C0G2E682J125AA (TDK Corporation) when C0G/NP0 temperature coefficient is specified. These parts offer ±5% tolerance and 250V rating with minimal capacitance drift across the operating temperature range. Both are active products suitable for new designs.

Avoid for New Designs: TDK Corporation parts C2012X7R2E682K125AA, C2012X7R2E682K125AM, and C2012X7R2E682M125AA are marked "Not For New Designs" and should be used only for legacy system maintenance or repair.

Compliance Verification: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 0805J2000682MXT with a part rated at 250V instead of 200V? A: Yes. A higher voltage rating (250V or greater) is electrically compatible and provides additional design margin. The capacitance value, tolerance, temperature coefficient, and package remain the primary compatibility factors. Verify PCB layout accommodates any thickness variations.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R provides ±15% capacitance change across -55°C to 125°C. C0G/NP0 provides ±0.3% change across the same range. C0G/NP0 is superior for applications requiring stable capacitance with temperature but typically at higher cost. Both are suitable for the 0805 package.

Q: Are KEMET, TDK, and YAGEO parts interchangeable in the 0805 package? A: Yes, all three manufacturers produce 0805 (2012 Metric) ceramic capacitors with identical footprints and mounting requirements. Physical thickness varies slightly (0.035" to 0.057"), which may affect PCB stackup but does not prevent interchangeability on standard designs.

Q: Why do some substitute parts have ±10% tolerance instead of ±20%? A: Tighter tolerance (±10% or ±5%) represents a manufacturing upgrade and is directly compatible with designs specified for ±20%. The part will perform within the original ±20% specification while offering improved consistency. No circuit redesign is required.

Q: Can I use C0805C682KBRAC7800 (630V) in place of the 200V original part? A: Yes. The 630V rating is a superset of the 200V requirement and maintains all other electrical parameters (6800 pF, X7R, -55°C to 125°C). Verify PCB layout accommodates the increased thickness (0.055" vs 0.051").

Q: What does "Not For New Designs" mean for TDK parts? A: This designation indicates the part is in mature production phase and may be discontinued. These parts remain available for existing designs and repairs but should not be selected for new product development. Use active product alternatives instead.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, matching the original 0805J2000682MXT regulatory requirements.
