Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1812CC222MATME are qualified based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 2200 pF (exact match required)
• Temperature Coefficient: X7R (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)

Allowable Variations:

• Voltage Rating: May be equal to or greater than 630V
• Tolerance: May be ±10% or ±20%
• Manufacturer: Different manufacturers permitted
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) acceptable

The identified substitute parts maintain all mandatory parameters while offering upgraded voltage ratings (2000V / 2kV) compared to the original 630V specification. This upgrade provides enhanced voltage margin for circuit protection without altering the electrical or mechanical footprint.

Parameter Comparison

Engineering Selection Recommendations

1812GC222KAT1A (KYOCERA AVX): This substitute maintains the same manufacturer as the original part while upgrading the voltage rating from 630V to 2000V. The tolerance is improved to ±10%, and the part is actively produced. Physical dimensions remain identical to the main part (0.181" L x 0.126" W, 0.071" max thickness). This option is suitable for direct replacement in applications requiring enhanced voltage margin.

C4532X7R3D222K130KA (TDK Corporation): This TDK equivalent provides 2000V rating with ±10% tolerance and active product status. Physical dimensions are slightly reduced (0.177" L x 0.126" W, 0.059" max thickness) compared to the original part. The smaller footprint may provide layout advantages in space-constrained applications while maintaining electrical compatibility.

C4532X7R3D222M130KA (TDK Corporation): This TDK option matches the original ±20% tolerance while providing 2000V voltage rating. However, this part carries "Not For New Designs" status, indicating it is in end-of-life phase. Selection of this part is not recommended for new circuit designs. The physical dimensions are identical to the C4532X7R3D222K130KA variant (0.177" L x 0.126" W, 0.059" max thickness).

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and the required X7R temperature coefficient across the full -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can the 1812CC222MATME be replaced with a higher voltage rated capacitor?

A: Yes. The substitute parts rated at 2000V (2kV) are electrically compatible with the original 630V specification. Higher voltage ratings provide increased safety margin and do not degrade circuit performance when the original voltage requirement is 630V or lower.

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

A: Tolerance specifies the allowable deviation from the nominal 2200 pF capacitance value. ±10% tolerance (1980 pF to 2420 pF) provides tighter capacitance control compared to ±20% tolerance (1760 pF to 2640 pF). Applications requiring precise capacitance values should specify ±10% tolerance parts.

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

A: The TDK parts (C4532X7R3D222K130KA and C4532X7R3D222M130KA) have slightly reduced physical dimensions (0.177" L x 0.126" W, 0.059" max thickness) compared to the KYOCERA AVX parts (0.181" L x 0.126" W, 0.071" max thickness). Both conform to the 1812 (4532 Metric) package standard and are surface mount compatible. The smaller TDK footprint may require PCB layout verification for tight spacing applications.

Q: What does "Not For New Designs" status mean?

A: Parts marked "Not For New Designs" are in end-of-life phase and should not be selected for new circuit development. The C4532X7R3D222M130KA carries this status. For new designs, select either 1812GC222KAT1A or C4532X7R3D222K130KA, both marked as Active.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts (1812GC222KAT1A, C4532X7R3D222K130KA, and C4532X7R3D222M130KA) are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part specifications.

Q: What packaging formats are available for these parts?

A: The 1812GC222KAT1A is supplied in Tape & Reel (TR) format. The C4532X7R3D222K130KA is available in Cut Tape (CT) & Digi-Reel® format. The C4532X7R3D222M130KA is supplied in Tape & Reel (TR) format. Packaging selection depends on assembly process requirements and volume specifications.
