1812SC222MAT1A\SB Equivalent & Substitute Parts

Part Overview

The 1812SC222MAT1A\SB is a 2200 pF ceramic capacitor rated at 1500V (1.5kV) with X7R temperature coefficient, manufactured by KYOCERA AVX in 1812 (4532 Metric) surface mount package. This component is actively produced and widely used in high-voltage general-purpose applications. Substitute parts are identified to provide alternatives with improved voltage ratings, tighter tolerances, or enhanced availability while maintaining core electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

• Capacitance: Must be 2200 pF (exact match required)
• Package / Case: Must be 1812 (4532 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Temperature Coefficient: X7R or X7S acceptable (both provide stable performance across -55°C ~ 125°C)
• Voltage Rating: Equal to or greater than 1500V (1.5kV)
• Tolerance: ±10% or ±20% acceptable
• Compliance: ROHS3 Compliant and REACH Unaffected required

Substitute parts are grouped into two categories:

Upgrade Substitutes (1812GC222KAT1A, C4532X7R3D222K130KA, C4532X7R3D222M130KA): Higher voltage rating (2000V / 2kV) with same or tighter tolerance, providing enhanced safety margin and component availability.

Manufacturer Recommended Substitute (C4532X7S3D222K160KA): Higher voltage rating (2000V / 2kV) with X7S temperature coefficient, offering improved performance characteristics while maintaining full compatibility.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: Select C4532X7R3D222K130KA (TDK Corporation) or 1812GC222KAT1A (KYOCERA AVX). Both are Active status components with 2000V rating, ±10% tolerance, and full ROHS3 compliance. The TDK part offers compact dimensions (4.50mm x 3.20mm vs. 4.60mm x 3.20mm) and reduced thickness (1.50mm vs. 1.80mm), beneficial for space-constrained layouts.

For Existing Designs: The 1812SC222MAT1A\SB remains the primary choice as an Active product. Direct substitution with 1812GC222KAT1A maintains KYOCERA AVX sourcing while upgrading voltage rating and tolerance.

For Enhanced Performance: C4532X7S3D222K160KA provides X7S temperature coefficient with tighter capacitance stability across the full operating range, suitable for applications requiring superior performance margins.

Avoid: C4532X7R3D222M130KA is marked "Not For New Designs" and should not be selected for new applications despite adequate electrical specifications.

All substitute parts maintain ROHS3 Compliant status, REACH Unaffected classification, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and environmental compliance.

Frequently Asked Questions (FAQ)

Q: Can C4532X7R3D222K130KA replace 1812SC222MAT1A\SB directly?

A: Yes. Both parts share identical capacitance (2200 pF), package (1812 / 4532 Metric), temperature coefficient (X7R), and operating temperature range (-55°C ~ 125°C). The TDK part provides higher voltage rating (2000V vs. 1500V) and tighter tolerance (±10% vs. ±20%), making it a direct electrical and mechanical substitute. Physical dimensions differ slightly (4.50mm x 3.20mm vs. 4.60mm x 3.20mm length), but both fit standard 1812 footprints.

Q: What is the difference between X7R and X7S temperature coefficients?

A: Both X7R and X7S are high-stability temperature coefficients suitable for -55°C ~ 125°C operation. X7S provides tighter capacitance tolerance across temperature extremes compared to X7R. For general-purpose applications, both are functionally equivalent. X7S selection is recommended when maximum capacitance stability is required.

Q: Why is C4532X7R3D222M130KA marked "Not For New Designs"?

A: This designation indicates the manufacturer (TDK) has discontinued active promotion of this part for new applications. While the component meets all electrical and compliance specifications, design engineers should select Active status alternatives (1812GC222KAT1A or C4532X7R3D222K130KA) to ensure long-term availability and supply chain stability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What packaging options are available?

A: The main part (1812SC222MAT1A\SB) is supplied in Bulk packaging. Substitute parts are available in Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, or Tape & Reel formats. Packaging selection depends on production volume and assembly equipment compatibility.

Q: Can I use a 2000V rated part in a 1500V application?

A: Yes. Higher voltage-rated components are suitable for lower-voltage applications. Using 2000V-rated substitutes in 1500V circuits provides additional safety margin and reliability. No derating or performance degradation occurs.
