1812SC222MAT9A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812SC222MAT9A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 2200 pF, rated voltage of 1500V (1.5kV), and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1812 (4532 Metric) package is designed for general-purpose applications requiring stable capacitance across a wide temperature range (-55°C to 125°C). The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts may be required due to inventory availability, packaging format preferences, or design upgrades to higher voltage ratings.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1812SC222MAT9A is determined by the following critical parameters that must remain constant or be upgraded:

Fixed Parameters (Must Match):

• Capacitance: 2200 pF (exact match required)
• Temperature Coefficient: X7R (ensures stable performance across operating temperature range)
• Package / Case: 1812 (4532 Metric) (maintains mechanical and electrical compatibility)
• Mounting Type: Surface Mount, MLCC (ensures PCB assembly compatibility)

Allowable Upgrade Parameters:

• Voltage - Rated: May be equal or higher than 1500V (1.5kV)
• Tolerance: May be equal or tighter than ±20%
• RoHS Status: Must maintain ROHS3 compliance or equivalent
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

The substitute parts identified (C4532X7R3D222K130KA and C4532X7R3D222M130KA) both maintain the core electrical specifications while offering upgraded voltage ratings of 2000V (2kV), representing a design upgrade path for applications requiring higher voltage margins.

Parameter Comparison

Engineering Selection Recommendations

C4532X7R3D222K130KA (TDK Corporation) - Preferred Substitute: This part is the primary equivalent for the 1812SC222MAT9A. It maintains all critical electrical parameters while providing a voltage upgrade to 2000V (2kV) and improved tolerance of ±10%. The part is in active production status, ensuring long-term availability. Packaging is available in Cut Tape (CT) and Digi-Reel format, supporting both manual and automated assembly workflows. ROHS3 compliance and MSL 1 rating confirm environmental and moisture handling compatibility.

C4532X7R3D222M130KA (TDK Corporation) - Secondary Substitute: This part provides identical electrical performance to the primary substitute with 2000V (2kV) rating and ±20% tolerance matching the original part. However, it carries a "Not For New Designs" product status, indicating it is in mature or declining production phase. This part should be selected only when C4532X7R3D222K130KA is unavailable and existing inventory must be maintained. Packaging is supplied in Tape & Reel (TR) format.

Both substitute parts exhibit slightly reduced physical dimensions (0.177" L vs. 0.181" L and 0.059" thickness vs. 0.071" thickness), which may require PCB layout verification to confirm clearance compatibility in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can C4532X7R3D222K130KA be used as a direct replacement for 1812SC222MAT9A? A: Yes. Both parts share identical capacitance (2200 pF), temperature coefficient (X7R), package (1812/4532 Metric), and operating temperature range (-55°C to 125°C). The TDK part provides upgraded voltage rating (2000V vs. 1500V) and tighter tolerance (±10% vs. ±20%), making it functionally compatible and electrically superior for the same application.

Q: What are the physical dimension differences between these parts? A: The KYOCERA AVX 1812SC222MAT9A measures 0.181" L x 0.126" W x 0.071" thickness. The TDK C4532X7R3D222K130KA measures 0.177" L x 0.126" W x 0.059" thickness. The length and thickness are slightly reduced. Verify PCB layout and component placement clearances before substitution in space-constrained designs.

Q: Why is C4532X7R3D222M130KA marked "Not For New Designs"? A: This designation indicates the part is in mature production phase with potential discontinuation risk. For new designs, C4532X7R3D222K130KA is the recommended choice due to active production status and improved tolerance specification.

Q: Are both TDK substitutes ROHS3 compliant? A: Yes. Both C4532X7R3D222K130KA and C4532X7R3D222M130KA are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), matching the environmental and compliance requirements of the original KYOCERA AVX part.

Q: What packaging formats are available for the substitute parts? A: C4532X7R3D222K130KA is available in Cut Tape (CT) and Digi-Reel format, supporting both manual and automated assembly. C4532X7R3D222M130KA is supplied in Tape & Reel (TR) format for automated assembly workflows.

Q: Can the higher voltage rating of the substitute parts cause any issues? A: No. A higher voltage rating (2000V vs. 1500V) provides additional safety margin and does not negatively affect circuit performance. The capacitance, temperature coefficient, and operating temperature range remain identical, ensuring functional equivalence.
