1812CC222MAT1A\SB Equivalent & Substitute Parts

Part Overview

The 1812CC222MAT1A\SB is a 2200 pF ceramic capacitor manufactured by KYOCERA AVX, rated for 630V with X7R temperature coefficient and ±20% tolerance. This surface mount multilayer ceramic capacitor (MLCC) in 1812 (4532 metric) package is designed for general purpose high voltage applications across the -55°C to 125°C operating temperature range. The part is currently active and ROHS3 compliant with MSL 1 rating.

Substitute parts become necessary when design requirements demand higher voltage ratings, improved tolerance specifications, or alternative manufacturer sourcing for supply chain optimization and inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1812CC222MAT1A\SB is determined by the following allowable parameters:

• Capacitance: Must remain 2200 pF (no deviation permitted)
• Temperature Coefficient: Must remain X7R (ensures stable capacitance across operating temperature range)
• Package / Case: Must remain 1812 (4532 Metric) (ensures mechanical and electrical compatibility)
• Mounting Type: Must remain Surface Mount, MLCC (ensures assembly compatibility)
• Operating Temperature Range: Must maintain -55°C to 125°C minimum specification
• RoHS & Compliance: Must maintain ROHS3 compliance and MSL 1 rating

Allowable variations in substitute parts:

• Voltage rating may be equal or higher than 630V
• Tolerance may be equal or tighter than ±20%
• Manufacturer may differ
• Packaging format may differ (Tape & Reel vs. Cut Tape)

Parameter Comparison

Engineering Selection Recommendations

1812GC222KAT1A (KYOCERA AVX) is the primary substitute option. It maintains the same manufacturer and package specifications while providing upgraded voltage rating (2000V vs. 630V) and improved tolerance (±10% vs. ±20%). Product status is Active, ensuring continued availability and support for new designs.

C4532X7R3D222K130KA (TDK Corporation) is a cross-manufacturer substitute with equivalent electrical performance to 1812GC222KAT1A. It offers 2000V rating and ±10% tolerance with Active product status. Physical dimensions vary slightly (0.177" L vs. 0.181" L; 0.059" thickness vs. 0.071" thickness), requiring verification of PCB layout compatibility.

C4532X7R3D222M130KA (TDK Corporation) is functionally equivalent to the main part with 2000V rating and ±20% tolerance. However, this part carries "Not For New Designs" status, limiting its suitability for new product development. Use only when existing inventory constraints or legacy system requirements necessitate this selection.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and the required -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1812CC222MAT1A\SB with a higher voltage rated capacitor?

A: Yes. Substitute parts with voltage ratings of 2000V (2kV) are electrically compatible. Higher voltage ratings provide additional design margin and do not degrade performance in circuits designed for 630V operation.

Q: What is the difference between ±20% and ±10% tolerance?

A: Tolerance specifies the allowable deviation from the nominal 2200 pF capacitance value. ±20% allows deviation from 1760 pF to 2640 pF, while ±10% restricts deviation to 1980 pF to 2420 pF. Applications requiring tighter capacitance control should select ±10% tolerance parts.

Q: Are TDK and KYOCERA AVX parts interchangeable?

A: Yes, when electrical parameters (capacitance, voltage, tolerance, temperature coefficient) and package specifications (1812 / 4532 Metric) are identical. Physical dimensions may vary slightly between manufacturers; verify PCB layout compatibility before assembly.

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

A: This designation indicates the manufacturer is phasing out this part number. While functionally equivalent, it should not be selected for new product development. Use C4532X7R3D222K130KA (±10% tolerance) or 1812GC222KAT1A as alternatives.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: No. Packaging format affects only handling, storage, and assembly logistics. Electrical and mechanical specifications remain identical regardless of packaging format.

Q: Can I use these capacitors in high frequency applications?

A: X7R temperature coefficient capacitors are suitable for general purpose applications across the specified temperature range. Specific high frequency performance characteristics are not provided in the technical parameters; consult detailed datasheets for frequency-dependent applications.
