1812SC222KAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1812SC222KAT1A is a 2200 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated for 1500V operation with X7R temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) in 1812 (4532 metric) package format is designed for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating temperature range. The part maintains active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when design requirements permit higher voltage ratings, alternative manufacturers, or modified temperature coefficient specifications while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1812SC222KAT1A are qualified based on the following criteria:

Mandatory Compatibility Parameters:

• Capacitance value: 2200 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Voltage Rating: May be equal to or higher than 1500V
• Temperature Coefficient: X7R or X7S (both acceptable for general-purpose applications)
• Manufacturer: Alternative qualified manufacturers permitted
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® acceptable

Three substitute parts meet these criteria with enhanced voltage ratings (2000V) and maintained or equivalent temperature stability characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory and environmental compatibility with the original 1812SC222KAT1A specification.

1812GC222KAT1A (KYOCERA AVX): Direct manufacturer upgrade within the same product family. Identical physical dimensions and mounting characteristics with enhanced 2000V voltage rating. Maintains X7R temperature coefficient. Highest inventory availability (21,100 units) supports production continuity.

C4532X7R3D222K130KA (TDK Corporation): Cross-manufacturer substitute with equivalent X7R temperature coefficient and 2000V voltage rating. Reduced physical thickness (1.50mm vs. 1.80mm) and slightly smaller length (4.50mm vs. 4.60mm) may require PCB layout verification for clearance-critical applications. Available in Cut Tape & Digi-Reel® packaging format.

C4532X7S3D222K160KA (TDK Corporation): Manufacturer-recommended substitute with X7S temperature coefficient (±22% capacitance change across operating range versus ±15% for X7R). Identical 2000V voltage rating and -55°C to 125°C operating range. X7S specification provides broader temperature stability margin for applications with extended thermal cycling requirements. Tape & Reel packaging format.

Frequently Asked Questions (FAQ)

Q: Can the 1812SC222KAT1A be directly replaced with a 2000V-rated substitute?

A: Yes. All substitute parts maintain identical capacitance (2200 pF), tolerance (±10%), package format (1812/4532 metric), and operating temperature range (-55°C to 125°C). Higher voltage ratings provide design margin without affecting electrical performance in circuits designed for 1500V operation.

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

A: X7R specifies ±15% maximum capacitance change across the -55°C to 125°C operating range. X7S specifies ±22% maximum capacitance change across the same range. Both maintain stable performance for general-purpose applications. X7S provides broader tolerance for temperature-sensitive circuits.

Q: Are there physical dimension differences between substitute parts?

A: The TDK C4532X7R3D222K130KA and C4532X7S3D222K160KA are slightly smaller (4.50mm length vs. 4.60mm, 1.50mm thickness vs. 1.80mm) than the KYOCERA AVX parts. The 1812GC222KAT1A maintains identical dimensions to the original 1812SC222KAT1A. PCB layout verification is recommended when switching between manufacturers to confirm clearance compatibility.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All parts listed are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level remains 1 (Unlimited) across all options.

Q: What packaging formats are available for these substitutes?

A: The 1812GC222KAT1A is supplied in Tape & Reel (TR) format. The TDK C4532X7R3D222K130KA is available in Cut Tape (CT) & Digi-Reel® format. The TDK C4532X7S3D222K160KA is supplied in Tape & Reel (TR) format. Packaging selection depends on assembly process requirements and volume specifications.
