1812AC222MATME Equivalent & Substitute Parts

Part Overview

The 1812AC222MATME is a 2200 pF, 1000V (1kV) ceramic capacitor manufactured by KYOCERA AVX with X7R temperature coefficient in 1812 (4532 Metric) surface mount package. This component is actively produced and widely used in general-purpose high-voltage applications. Substitute parts are identified based on matching or exceeding electrical specifications while maintaining mechanical compatibility with the 1812 package footprint.

Substitute Part Grouping Explanation

Substitution eligibility for the 1812AC222MATME is determined by the following criteria:

Mandatory Matching Parameters:

Capacitance: 2200 pF (exact match required)
Package / Case: 1812 (4532 Metric) (mechanical compatibility)
Mounting Type: Surface Mount, MLCC
Operating Temperature Range: -55°C ~ 125°C (minimum)
RoHS3 Compliance and MSL 1 rating

Allowable Variations:

Voltage Rating: Equal to or greater than 1000V
Tolerance: Equal to or tighter than ±20%
Temperature Coefficient: X7R, X7S, or C0G/NP0 (all acceptable for general-purpose applications)

Substitute parts are grouped into three categories based on voltage rating and temperature coefficient characteristics.

Engineering Selection Recommendations

Direct Equivalent (Same Voltage Rating):

1812AA222JAT1A (KYOCERA AVX): Offers tighter tolerance (±5% vs ±20%) with C0G/NP0 temperature coefficient, providing superior stability. Recommended for applications requiring improved capacitance accuracy. Active product status ensures long-term availability.

Upgraded Substitutes (Higher Voltage Rating):

1812GC222KAT1A (KYOCERA AVX): Doubles voltage rating to 2000V while maintaining X7R characteristics. Suitable for applications with potential voltage transients or design margin requirements. Active product with high inventory availability.
C4532X7R3D222K130KA (TDK Corporation): Equivalent to 1812GC222KAT1A with 2000V rating and ±10% tolerance. Active product status supports new designs.
C4532X7S3D222K160KA (TDK Corporation): Provides 2000V rating with X7S temperature coefficient (wider temperature stability than X7R). Active product designated as manufacturer-recommended substitute.

Not Recommended for New Designs:

C4532X7R3D222M130KA (TDK Corporation): Although electrically compatible, this part carries "Not For New Designs" status and should be avoided in new applications.

All recommended substitutes maintain ROHS3 compliance, MSL 1 rating, and -55°C ~ 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can 1812AA222JAT1A replace 1812AC222MATME directly? A: Yes. Both parts share identical capacitance (2200 pF), voltage rating (1000V), and 1812 package. The substitute offers tighter tolerance (±5% vs ±20%) and C0G/NP0 temperature coefficient, making it a direct upgrade for applications requiring improved stability.

Q: What is the advantage of using 1812GC222KAT1A or C4532X7R3D222K130KA? A: These parts double the voltage rating to 2000V while maintaining the same capacitance and package. They are suitable for applications where higher voltage margin is required or where voltage transients may occur. Both are active products with strong inventory availability.

Q: Are TDK parts compatible with KYOCERA AVX footprints? A: Yes. All substitute parts use the 1812 (4532 Metric) package, ensuring mechanical and electrical compatibility. Dimensional variations (length 4.60mm vs 4.50mm, thickness 1.80mm vs 1.50mm) are within standard PCB assembly tolerances.

Q: Why is C4532X7R3D222M130KA marked "Not For New Designs"? A: This designation indicates the manufacturer is phasing out this part number. While electrically compatible, it should not be used in new product designs to ensure long-term supply chain stability.

Q: What is the difference between X7R and X7S temperature coefficients? A: Both are acceptable for general-purpose applications. X7S provides wider temperature stability (±22% capacitance change over -55°C to 125°C) compared to X7R (±15%). C0G/NP0 offers the tightest stability (±0.3%) but is limited to lower voltage ratings in this product line.

Q: Can I use C4532X7S3D222K160KA in place of the original part? A: Yes. This part meets all substitution criteria with 2000V rating, ±10% tolerance, and X7S temperature coefficient. It is designated as the manufacturer-recommended substitute and is actively produced.
