Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Substitution Criteria (Mandatory Match):

• Capacitance: 2200 pF (exact match required)
• Package / Case: 1812 (4532 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Secondary Substitution Criteria (Allowable Variation):

• Voltage Rating: Equal to or greater than 1000V
• Tolerance: Equal to or tighter than ±20%
• Temperature Coefficient: C0G/NP0 or X7R/X7S (functionally equivalent for general-purpose applications)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet or exceed the primary criteria. Secondary criteria variations represent performance enhancements or alternative dielectric materials suitable for the same application space.

Parameter Comparison

Engineering Selection Recommendations

1812AA222JAT1A (KYOCERA AVX Upgrade) This part maintains identical electrical specifications to the main part with improved tolerance (±5% versus ±20%). Both components use C0G/NP0 dielectric material and are rated for 1000V. Selection of this part provides tighter capacitance tolerance while preserving the same voltage rating and temperature stability characteristics. Available in Tape & Reel packaging.

1812GC222KAT1A (KYOCERA AVX MFR Recommended) This part increases voltage rating to 2000V (2kV) while maintaining 2200 pF capacitance. Temperature coefficient changes from C0G/NP0 to X7R, which provides wider temperature stability range suitable for general-purpose applications. Tolerance is ±10%. This configuration is recommended when higher voltage margin is required in the circuit design.

C4532X7R3D222K130KA (TDK Corporation MFR Recommended) TDK equivalent with 2000V rating and X7R temperature coefficient. Physical dimensions vary slightly (0.177" L x 0.126" W versus 0.181" L x 0.126" W; thickness 0.059" versus 0.071"). Functionally equivalent for 1812 (4532 Metric) footprint applications. Available in Cut Tape and Digi-Reel packaging.

C4532X7S3D222K160KA (TDK Corporation MFR Recommended) TDK equivalent with 2000V rating and X7S temperature coefficient. X7S provides enhanced temperature stability compared to X7R across the -55°C to 125°C operating range. Physical dimensions match C4532X7R3D222K130KA. Available in Tape & Reel packaging.

All substitute parts maintain ROHS3 compliance, Moisture Sensitivity Level 1 (Unlimited), and active product status.

Frequently Asked Questions (FAQ)

Q: Can 1812AA222JAT1A replace 1812AA222MATME directly? A: Yes. Both parts share identical capacitance (2200 pF), voltage rating (1000V), temperature coefficient (C0G/NP0), package (1812), and operating temperature range (-55°C to 125°C). The substitute offers improved tolerance (±5% versus ±20%), representing a performance upgrade with no functional compromise.

Q: What is the difference between C0G/NP0 and X7R temperature coefficients? A: C0G/NP0 provides near-zero capacitance change across the operating temperature range, offering superior stability. X7R provides capacitance change within ±15% across the temperature range. For general-purpose applications, both are acceptable; C0G/NP0 is preferred when temperature stability is critical.

Q: Why do TDK parts have different physical dimensions? A: C4532X7R3D222K130KA and C4532X7S3D222K160KA have slightly smaller length (0.177" versus 0.181") and thickness (0.059" versus 0.071"). These dimensions remain within the 1812 (4532 Metric) package classification and are compatible with standard 1812 footprints. Verify PCB layout clearances if space is constrained.

Q: Can I use a 2000V rated part in place of a 1000V rated part? A: Yes. Higher voltage rating provides additional safety margin and is electrically compatible. Parts 1812GC222KAT1A, C4532X7R3D222K130KA, and C4532X7S3D222K160KA are all rated for 2000V and function correctly in 1000V applications.

Q: What packaging options are available? A: 1812AA222MATME uses standard packaging (not specified). Substitutes are available in Tape & Reel (TR) for 1812AA222JAT1A, 1812GC222KAT1A, and C4532X7S3D222K160KA. C4532X7R3D222K130KA is available in Cut Tape (CT) and Digi-Reel packaging. Verify packaging compatibility with assembly equipment.

Q: Are all parts ROHS3 compliant? A: Yes. All listed parts, including the main part and all substitutes, are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
