1812CC683MAT3A Equivalent & Substitute Parts

Part Overview

The 1812CC683MAT3A is a 0.068 µF ceramic capacitor rated for 630V with X7R temperature coefficient, manufactured by KYOCERA AVX in 1812 (4532 Metric) surface mount package. This high-voltage MLCC is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active and ROHS3 compliant with MSL 1 rating.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter ranges for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

• Capacitance value must be 0.068 µF
• Voltage rating must be 630V or higher
• Temperature coefficient must be X7R
• Operating temperature range must encompass -55°C to 125°C
• Package must be 1812 (4532 Metric) surface mount
• RoHS3 compliance and MSL 1 rating required
• Tolerance may vary within ±10% to ±20% range

The substitute parts listed maintain all critical electrical parameters and mechanical compatibility with the main part number.

Parameter Comparison

Engineering Selection Recommendations

1812CC683KAT1A (KYOCERA AVX) — Upgrade substitute with improved tolerance specification (±10% vs ±20%). Same manufacturer as main part, active product status, identical physical dimensions and electrical ratings. Recommended for applications requiring tighter capacitance tolerance.

GRM43QR72J683KW01L (Murata Electronics) — Upgrade substitute with improved tolerance specification (±10% vs ±20%). Reduced thickness (1.50mm vs 2.20mm) provides space optimization benefit. Active product status with full compliance certifications.

C4532X7R2J683M160KA (TDK Corporation) — Equivalent substitute with matching ±20% tolerance. Product status is "Not For New Designs," indicating this part is in mature phase. Suitable for legacy system maintenance and repair applications only. Thickness specification is 1.80mm.

Frequently Asked Questions (FAQ)

Q: Can 1812CC683KAT1A replace 1812CC683MAT3A in new designs? A: Yes. Both parts are manufactured by KYOCERA AVX with active product status. The substitute offers improved tolerance (±10% vs ±20%) while maintaining identical electrical ratings, voltage, temperature coefficient, and package specifications.

Q: What is the difference between the Murata and KYOCERA AVX options? A: Both GRM43QR72J683KW01L and 1812CC683KAT1A meet all electrical requirements. The Murata part offers reduced thickness (1.50mm vs 2.20mm), which may provide PCB layout advantages. Both are active products with ±10% tolerance.

Q: Why is C4532X7R2J683M160KA marked "Not For New Designs"? A: This TDK part is in mature/legacy phase. It remains available for existing system support and repair but should not be selected for new product development. Use 1812CC683KAT1A or GRM43QR72J683KW01L for new designs.

Q: Are there physical compatibility concerns with the thickness variations? A: The substitute parts have different maximum thicknesses (1.50mm to 2.20mm) but all conform to the 1812 (4532 Metric) package standard. PCB footprint and land pattern compatibility is maintained. Verify clearance in your specific application if height-constrained.

Q: Do all substitutes maintain the same moisture sensitivity rating? A: Yes. All listed parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity precautions are required during storage or handling.
