Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812CC682MAT1A\SB is determined by the following critical parameters:

• Capacitance Value: Must remain 6800 pF to maintain circuit functionality
• Package Footprint: Must be 1812 (4532 Metric) to ensure PCB compatibility
• Mounting Type: Must be Surface Mount MLCC to align with assembly process
• Temperature Coefficient: Must be X7R to preserve temperature stability characteristics
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Compliance Standards: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part 1812GC682KAT1A meets all mandatory substitution criteria while offering enhanced voltage rating (2000V versus 630V) and improved tolerance (±10% versus ±20%). This upgrade provides greater design margin and component reliability without compromising package compatibility or thermal performance.

Parameter Comparison

Engineering Selection Recommendations

Both the 1812CC682MAT1A\SB and 1812GC682KAT1A are Active products manufactured by KYOCERA AVX with full ROHS3 compliance and MSL 1 rating, ensuring regulatory alignment and manufacturing compatibility. The primary distinction lies in voltage rating and tolerance specifications.

Selection of 1812CC682MAT1A\SB is appropriate for applications where the 630V rating meets circuit requirements and cost optimization is prioritized. Selection of 1812GC682KAT1A is appropriate for applications requiring enhanced voltage margin, improved tolerance performance, or where the 2000V rating provides design flexibility for future circuit modifications. The increased maximum thickness (2.80mm versus 1.80mm) of the substitute part must be verified against PCB assembly clearance constraints.

Frequently Asked Questions (FAQ)

Q: Can 1812GC682KAT1A be used as a direct replacement for 1812CC682MAT1A\SB?

A: Yes, provided PCB assembly clearance accommodates the increased thickness (2.80mm maximum for the substitute versus 1.80mm for the original). Both parts share identical capacitance, package footprint, mounting type, and temperature coefficient. The substitute offers higher voltage rating and tighter tolerance.

Q: What is the significance of the voltage rating difference between 630V and 2000V?

A: Voltage rating defines the maximum continuous voltage the capacitor can withstand. The 2000V rating of the substitute part provides greater design margin in high-voltage applications and reduces stress on the dielectric material, potentially extending component life in circuits operating near the original 630V specification.

Q: Does the tolerance difference (±20% versus ±10%) affect circuit performance?

A: Tolerance defines the acceptable capacitance variation from the nominal 6800 pF value. The ±10% tolerance of the substitute part provides tighter capacitance control, which may be beneficial in precision filtering, timing, or resonant circuits where capacitance accuracy is critical.

Q: Are there any thermal performance differences between these parts?

A: Both parts feature X7R temperature coefficient and operate across -55°C to 125°C. X7R classification ensures capacitance variation remains within ±15% across this temperature range, providing equivalent thermal stability for both parts.

Q: What packaging format is available for the substitute part?

A: The 1812GC682KAT1A is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. Confirm packaging compatibility with your procurement and assembly requirements.
