Parameter Comparison

Engineering Selection Recommendations

1812GC222KAT1A (KYOCERA AVX) - Upgrade Substitute

This part represents a direct upgrade from the original 1812GC222MAT1A. Both components are manufactured by KYOCERA AVX with identical physical dimensions (4.60mm x 3.20mm x 1.80mm) and electrical ratings. The primary improvement is the tighter capacitance tolerance of ±10% compared to ±20%, providing enhanced circuit performance predictability. Product status is Active with full ROHS3 compliance. Inventory availability is significantly higher (21,100 units) compared to the original part (897 units). This substitute is recommended as the primary alternative when KYOCERA AVX sourcing is preferred.

C4532X7R3D222K130KA (TDK Corporation) - Upgrade Substitute

This TDK part matches all critical electrical parameters with ±10% tolerance specification. The component is Active status and ROHS3 compliant. Physical dimensions are slightly reduced (4.50mm x 3.20mm x 1.50mm) compared to the original, which may provide PCB layout advantages in space-constrained applications. Packaging is available in Cut Tape (CT) & Digi-Reel® format. This substitute is suitable for new designs requiring TDK component sourcing.

C4532X7S3D222K160KA (TDK Corporation) - Manufacturer Recommended Substitute

This part is designated as manufacturer-recommended and represents the highest specification option. The X7S temperature coefficient provides tighter temperature stability compared to X7R, with ±10% tolerance. All electrical ratings match the original specification at 2000V with 2200 pF capacitance. Product status is Active with ROHS3 compliance. Physical dimensions are 4.50mm x 3.20mm. This substitute is appropriate for applications requiring superior temperature coefficient performance.

C4532X7R3D222M130KA (TDK Corporation) - Legacy Substitute

This TDK part maintains electrical compatibility with ±20% tolerance matching the original specification. However, product status is listed as "Not For New Designs," indicating this component is in end-of-life phase. This substitute is suitable only for replacement or repair of existing assemblies where component continuity is required. New design implementations should avoid this part number.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1812GC222KAT1A for 1812GC222MAT1A without circuit redesign?

A: Yes. Both parts share identical capacitance (2200 pF), voltage rating (2000V), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and physical package dimensions (1812/4532 Metric). The primary difference is improved tolerance (±10% vs ±20%), which enhances circuit performance without requiring design modification.

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

A: Both temperature coefficients are acceptable for this application. X7R provides ±15% capacitance variation across the operating temperature range, while X7S provides ±22% variation. X7S offers tighter temperature stability characteristics. Selection depends on circuit requirements for temperature-dependent capacitance behavior.

Q: Are the TDK parts physically compatible with the original KYOCERA AVX part?

A: TDK parts C4532X7R3D222K130KA and C4532X7S3D222K160KA have slightly reduced dimensions (4.50mm x 3.20mm x 1.50mm) compared to the original (4.60mm x 3.20mm x 1.80mm). These dimensional differences are within standard PCB pad tolerance specifications and are physically compatible. The reduced thickness may provide additional PCB routing clearance.

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

A: This designation indicates the component is in end-of-life phase and manufacturer production is being discontinued. While the part remains electrically and mechanically compatible, it should not be selected for new product development. Use this part only for replacement or repair of existing assemblies.

Q: What packaging formats are available for these substitute parts?

A: 1812GC222KAT1A is available in Tape & Reel (TR) format. C4532X7R3D222K130KA is available in Cut Tape (CT) & Digi-Reel® format. C4532X7S3D222K160KA is available in Tape & Reel (TR) format. Selection depends on assembly equipment compatibility and procurement requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance status, matching the original 1812GC222MAT1A specification. Moisture Sensitivity Level is 1 (Unlimited) for all parts, indicating no special storage or handling requirements.
