KYOCERA AVX 1812SC822MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1812SC822MAT1A is an 8200 pF high-voltage ceramic capacitor rated at 1500V with X7R temperature coefficient, housed in a 1812 (4532 Metric) surface-mount package. This component is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative models may be required when design specifications demand higher voltage ratings, improved tolerance characteristics, or specific packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812SC822MAT1A is determined by the following critical parameters:

Fixed Requirements (Non-Negotiable):

• Capacitance value: 8200 pF
• Package type: 1812 (4532 Metric)
• Temperature coefficient: X7R
• Mounting type: Surface Mount, MLCC
• Physical dimensions: 0.181" L × 0.126" W (4.60mm × 3.20mm)
• Thickness: 0.110" (2.80mm)

Allowable Variation Parameters:

• Voltage rating: Equal to or greater than 1500V
• Tolerance: Equal to or tighter than ±20%
• Operating temperature range: Must encompass -55°C to 125°C
• Compliance certifications: RoHS3, REACH Unaffected

The substitute part 1812GC822KAT1A qualifies as a direct upgrade substitute because it maintains identical capacitance, package, and temperature coefficient specifications while providing enhanced voltage rating (2000V vs. 1500V) and improved tolerance (±10% vs. ±20%).

Parameter Comparison

Engineering Selection Recommendations

The 1812GC822KAT1A serves as a direct substitute for the 1812SC822MAT1A in applications where the original part specifications are met or exceeded. Both components maintain Active product status with identical RoHS3 and REACH compliance certifications, ensuring regulatory alignment across supply chain transitions.

The substitute part provides enhanced performance margins through increased voltage rating (2000V vs. 1500V) and tighter capacitance tolerance (±10% vs. ±20%), making it suitable for designs requiring higher reliability or stricter component tolerances. Physical compatibility is guaranteed, as both parts share identical package dimensions, thickness, and surface-mount configuration.

Selection between these parts depends on design voltage requirements and tolerance specifications. The 1812SC822MAT1A remains appropriate for applications operating at or below 1500V with ±20% tolerance acceptance. The 1812GC822KAT1A is specified for designs requiring 2000V rating capability or ±10% tolerance performance.

Frequently Asked Questions (FAQ)

Q: Can the 1812GC822KAT1A replace the 1812SC822MAT1A in existing designs?

A: Yes. The substitute part maintains identical capacitance (8200 pF), package type (1812), temperature coefficient (X7R), and physical dimensions. It provides higher voltage rating and improved tolerance, making it electrically and mechanically compatible for direct substitution.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating (1500V vs. 2000V) and tolerance (±20% vs. ±10%). The 1812GC822KAT1A offers enhanced performance specifications while maintaining all other electrical and mechanical characteristics.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 1812SC822MAT1A and 1812GC822KAT1A are ROHS3 Compliant with REACH Unaffected status, meeting current environmental and regulatory requirements.

Q: Do these parts have identical physical dimensions?

A: Yes. Both components are housed in 1812 (4532 Metric) packages with dimensions of 0.181" L × 0.126" W (4.60mm × 3.20mm) and maximum thickness of 0.110" (2.80mm), ensuring identical PCB footprint and assembly compatibility.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.

Q: Can the 1812SC822MAT1A be used where the 1812GC822KAT1A is specified?

A: No. The 1812SC822MAT1A has a lower voltage rating (1500V vs. 2000V) and wider tolerance (±20% vs. ±10%). It does not meet the enhanced specifications of the substitute part and should not be used as a downgrade replacement.
