1210SC222MAT1A Equivalent & Substitute Parts

Part Overview

The 1210SC222MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 2200 pF, rated voltage of 1500V (1.5kV), and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1210 (3225 Metric) package is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -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 are identified to provide design flexibility, accommodate supply chain variations, or meet specific performance requirements while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1210SC222MAT1A is determined by the following critical parameters: capacitance value (2200 pF), package type (1210/3225 Metric), mounting method (surface mount), and operating temperature range (-55°C to 125°C). All identified substitute parts maintain these core specifications.

The substitute parts are grouped into two categories:

Upgrade Substitutes (Same Voltage Rating): Parts with identical or tighter tolerance specifications and the same 1500V voltage rating as the main part, enabling direct replacement with improved performance characteristics.

Manufacturer-Recommended Substitute (Higher Voltage Rating): A part with elevated voltage rating (2000V) and alternative temperature coefficient (X7S instead of X7R), suitable for applications requiring enhanced voltage margin or different thermal stability characteristics.

Parameter Comparison

Engineering Selection Recommendations

1210SC222KAT1A (KYOCERA AVX Upgrade): This part is a direct functional equivalent with improved tolerance (±10% versus ±20%), maintaining identical voltage rating and package dimensions. Selection is appropriate when tighter capacitance tolerance is required without modifying circuit design parameters.

1210GC222KAT1A (KYOCERA AVX Upgrade): This part provides the same tolerance improvement as 1210SC222KAT1A with elevated voltage rating (2000V versus 1500V). The reduced thickness (1.80mm versus 2.20mm) may provide board-level design advantages. Selection is appropriate for applications requiring enhanced voltage margin or space-constrained layouts.

C3225X7S3D222K250AA (TDK Corporation MFR Recommended): This part is manufacturer-recommended and offers 2000V voltage rating with X7S temperature coefficient. The X7S coefficient provides tighter capacitance stability over temperature compared to X7R, with a trade-off of slightly increased thickness (2.80mm). Dimensional variation in length (3.20mm versus 3.30mm) requires footprint verification. Selection is appropriate when cross-manufacturer sourcing is acceptable and enhanced thermal stability is beneficial.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and active product status, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can 1210SC222KAT1A be used as a direct replacement for 1210SC222MAT1A?

A: Yes. Both parts share identical capacitance (2200 pF), voltage rating (1500V), temperature coefficient (X7R), package (1210/3225 Metric), and operating temperature range (-55°C to 125°C). The 1210SC222KAT1A offers improved tolerance (±10% versus ±20%), making it functionally compatible with no circuit modifications required.

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

A: X7R and X7S are both temperature coefficient classifications for ceramic capacitors. X7R provides ±15% capacitance change over the -55°C to 125°C range, while X7S provides ±22% change. Both maintain stable performance across the operating temperature range. X7S offers tighter initial tolerance but slightly broader temperature drift characteristics.

Q: Can I use the 2000V-rated parts (1210GC222KAT1A or C3225X7S3D222K250AA) in place of the 1500V-rated main part?

A: Yes. Higher voltage-rated capacitors are functionally compatible in circuits designed for lower voltage ratings. The 2000V parts provide additional voltage margin and are suitable for direct substitution. No circuit modifications are required.

Q: Are there dimensional compatibility concerns with C3225X7S3D222K250AA?

A: The C3225X7S3D222K250AA has a length of 3.20mm compared to 3.30mm for the main part and other KYOCERA AVX substitutes. The thickness is also increased to 2.80mm. Footprint verification is required to confirm PCB layout compatibility before selection.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts listed, including the main part and all substitutes, have MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage and handling.

Q: What is the inventory status of these parts?

A: The main part 1210SC222MAT1A has 3100 pieces in stock. Substitute parts have the following inventory: 1210SC222KAT1A (4382 pcs), 1210GC222KAT1A (3369 pcs), and C3225X7S3D222K250AA (3217 pcs).
