1812SC222MATME Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 1812SC222MATME 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 general-purpose high-voltage applications. Substitute parts are identified to address inventory availability, enhanced voltage ratings, or alternative manufacturer sourcing while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1812SC222MATME is determined by the following allowable parameters:

• Capacitance: Must remain 2200 pF (no deviation permitted)
• Package / Case: Must remain 1812 (4532 Metric) for mechanical and PCB compatibility
• Mounting Type: Must remain Surface Mount, MLCC
• Temperature Coefficient: X7R or X7S acceptable (both provide stable capacitance across operating temperature range)
• Voltage Rating: May be equal to or greater than 1500V (1.5kV); higher ratings provide design margin
• Tolerance: May be ±10% or ±20%; tighter tolerance (±10%) represents an upgrade
• RoHS / REACH Compliance: Must maintain ROHS3 Compliant and REACH Unaffected status
• Moisture Sensitivity Level: Must remain MSL 1 (Unlimited)

Substitute parts are grouped into upgrade categories based on voltage rating enhancement and tolerance improvement.

Engineering Selection Recommendations

For Active Production Designs: Select C4532X7R3D222K130KA (TDK Corporation) or 1812GC222KAT1A (KYOCERA AVX). Both parts are actively produced, offer 2000V voltage rating (33% higher than the main part), and provide ±10% tolerance. These parts maintain full ROHS3 compliance and MSL 1 rating. Dimensional compatibility is confirmed for PCB assembly.

For Designs Requiring Manufacturer Continuity: Select 1812GC222KAT1A to maintain KYOCERA AVX sourcing while achieving voltage and tolerance upgrades.

For Cross-Manufacturer Sourcing: Select C4532X7R3D222K130KA (TDK Corporation) as the primary alternative. This part maintains identical electrical specifications to the KYOCERA AVX upgrade option with confirmed active production status.

Not Recommended for New Designs: C4532X7R3D222M130KA carries "Not For New Designs" status and should not be selected for new product development, despite meeting electrical and mechanical compatibility criteria.

Temperature Coefficient Consideration: C4532X7S3D222K160KA features X7S temperature coefficient instead of X7R. Both coefficients provide stable capacitance across the -55°C ~ 125°C operating range. X7S offers slightly wider capacitance tolerance across temperature extremes. This part is manufacturer-recommended and actively produced.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 1812SC222MATME with a part rated at 1000V instead of 1500V or higher? A: No. Voltage rating must be equal to or greater than 1500V. Lower voltage ratings do not meet the electrical requirements of the original specification.

Q: Are the dimensional differences between KYOCERA AVX and TDK parts significant for PCB assembly? A: The length difference (0.181" vs 0.177") and thickness difference (0.071" vs 0.059") are within standard PCB design tolerances for 1812 package components. Both footprints are mechanically compatible with standard 1812 (4532 Metric) land patterns. Verify PCB layout clearances if space constraints exist.

Q: What is the difference between X7R and X7S temperature coefficients? A: Both X7R and X7S provide stable capacitance across the -55°C ~ 125°C operating range. X7S exhibits slightly broader capacitance variation across temperature extremes but remains within acceptable limits for general-purpose applications. Selection between them depends on circuit-specific tolerance requirements.

Q: Why is C4532X7R3D222M130KA marked "Not For New Designs"? A: This designation indicates the manufacturer has discontinued active promotion of this part for new product development. While electrically and mechanically compatible, it should not be selected for designs entering production or long-term deployment.

Q: Can I use a ±10% tolerance part as a substitute for a ±20% tolerance requirement? A: Yes. A ±10% tolerance part meets or exceeds a ±20% tolerance requirement. The tighter tolerance represents an upgrade in component precision.

Q: Are all substitute parts ROHS3 compliant and MSL 1 rated? A: Yes. All listed substitute parts maintain ROHS3 Compliant status and MSL 1 (Unlimited) moisture sensitivity level, matching the original part's environmental and regulatory compliance.
