Equivalent & Substitute Parts for 1812GA221MAT1A\SB

Part Overview

The 1812GA221MAT1A\SB is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 220 pF, rated voltage of 2000V (2kV), and C0G/NP0 temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1812 (4532 Metric) package is designed for general-purpose applications requiring stable capacitance across temperature ranges from -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts may be required due to inventory availability, lead time considerations, or specific application requirements for enhanced voltage ratings or tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1812GA221MAT1A\SB is determined by the following critical parameters:

• Capacitance Value: Must be 220 pF
• Temperature Coefficient: Must be C0G or NP0
• Package / Case: Must be 1812 (4532 Metric)
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C
• Voltage Rating: Must be equal to or greater than 2000V (2kV)
• Tolerance: ±20% or tighter (±10% acceptable)
• Compliance: ROHS3 Compliant, MSL 1

Two substitute parts meet these criteria:

Upgrade Substitute (Higher Voltage Rating): C4532C0G3F221K200KA by TDK Corporation provides enhanced voltage rating of 3000V (3kV) with tighter tolerance (±10%) while maintaining identical capacitance, package, and temperature coefficient specifications.

Equivalent Substitute (Matched Specifications): C1812C221MGGAC7800 by KEMET provides identical electrical specifications (220 pF, ±20%, 2000V, C0G/NP0) with the same package and operating temperature range, with the additional feature of low ESL design.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Matched Specifications): C1812C221MGGAC7800 (KEMET) is suitable for direct substitution where the original 1812GA221MAT1A\SB specifications are required. This part maintains identical electrical parameters (220 pF, ±20%, 2000V, C0G/NP0) and package dimensions, with the added benefit of low ESL characteristics. All compliance certifications (ROHS3, REACH Unaffected, EAR99) are equivalent.

For Enhanced Voltage Margin Applications: C4532C0G3F221K200KA (TDK) provides a 50% increase in voltage rating (3000V vs. 2000V) with improved tolerance specification (±10% vs. ±20%). This upgrade option is applicable when circuit design permits higher voltage-rated components or when additional safety margin is required. Dimensional variations are minimal (length 4.50mm vs. 4.60mm), and all compliance requirements are met.

Both substitute parts are active products with established inventory availability and maintain full regulatory compliance with the original specification.

Frequently Asked Questions (FAQ)

Q: Can C4532C0G3F221K200KA (TDK, 3kV) be used in place of 1812GA221MAT1A\SB (KYOCERA AVX, 2kV)?

A: Yes. The TDK part meets all substitution criteria with identical capacitance (220 pF), temperature coefficient (C0G/NP0), package (1812/4532 Metric), and operating temperature range (-55°C ~ 125°C). The higher voltage rating (3kV vs. 2kV) is compatible with circuits designed for 2kV operation. Tolerance is tighter (±10% vs. ±20%), which is acceptable. Dimensional differences are negligible (length 4.50mm vs. 4.60mm).

Q: Can C1812C221MGGAC7800 (KEMET, 2kV) be used in place of 1812GA221MAT1A\SB (KYOCERA AVX, 2kV)?

A: Yes. The KEMET part is a direct equivalent with matching capacitance (220 pF), voltage rating (2000V), tolerance (±20%), temperature coefficient (C0G/NP0), package (1812/4532 Metric), and operating temperature range (-55°C ~ 125°C). The low ESL feature is an additional benefit. Thickness is reduced (1.55mm vs. 2.20mm), which may provide layout advantages.

Q: Are there dimensional compatibility concerns with these substitutes?

A: Both substitute parts use the 1812 (4532 Metric) package with minor length variations. The TDK part measures 4.50mm length versus 4.60mm for the original KYOCERA AVX part. The KEMET part also measures 4.50mm length. These differences are within standard PCB footprint tolerances for 1812 components. The KEMET part has reduced thickness (1.55mm vs. 2.20mm), which is compatible with standard 1812 footprints.

Q: Do all parts meet the same regulatory and compliance requirements?

A: Yes. All three parts (original and both substitutes) are ROHS3 Compliant, REACH Unaffected, and classified as EAR99. All maintain MSL 1 (Unlimited) moisture sensitivity level, requiring no special handling or storage conditions.

Q: What is the difference between C0G and NP0 temperature coefficients?

A: C0G and NP0 are equivalent designations for the same temperature coefficient characteristic. C0G is the EIA standard designation, while NP0 is the IEC standard designation. Both indicate zero temperature coefficient performance across the operating range (-55°C ~ 125°C).

Q: Can these parts be used interchangeably in high-frequency applications?

A: Substitution suitability for high-frequency applications depends on circuit-specific requirements not provided in the component specifications. The KEMET part (C1812C221MGGAC7800) includes a low ESL feature, which may provide advantages in high-frequency circuits. Consult application-specific design requirements for frequency-dependent performance criteria.
