2225SC223KAT3A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 2225SC223KAT3A is a 0.022 µF ceramic capacitor rated for 1500V (1.5kV) operation, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring reliable performance across the -55°C to 125°C operating temperature range. The part is currently active in production with 1104 units in stock. Substitute parts are identified when design requirements necessitate higher voltage ratings, improved availability, or alternative packaging configurations while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2225SC223KAT3A is determined by the following criteria:

Mandatory Compatibility Parameters:

• Capacitance value: 0.022 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package / Case: 2225 (5763 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Physical dimensions: 5.72mm L × 6.35mm W (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)

Allowable Variation Parameters:

• Voltage Rating: May be equal to or higher than 1500V
• Packaging format: May differ (e.g., Tape & Reel vs. bulk)
• Manufacturer: May differ if all electrical and mechanical parameters align

The 2225WC223KAT1A qualifies as a substitute because it maintains identical capacitance, tolerance, temperature coefficient, package dimensions, and operating temperature range while providing an upgraded voltage rating of 2500V (2.5kV).

Parameter Comparison

Engineering Selection Recommendations

Both the 2225SC223KAT3A and 2225WC223KAT1A are active production parts manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on circuit voltage requirements:

• 2225SC223KAT3A is appropriate for applications with maximum operating voltages up to 1500V.
• 2225WC223KAT1A is suitable for applications requiring voltage ratings up to 2500V and offers higher design margin in high-voltage circuits. This part also provides greater inventory availability (2585 units in stock versus 1104 units).

Both parts share identical physical footprints, capacitance values, and temperature characteristics, ensuring direct PCB compatibility. The substitute part's higher voltage rating does not degrade performance in lower-voltage applications and may provide improved reliability through increased voltage margin.

Frequently Asked Questions (FAQ)

Q: Can 2225WC223KAT1A replace 2225SC223KAT3A in existing designs?

A: Yes. The substitute part maintains identical capacitance (0.022 µF), tolerance (±10%), temperature coefficient (X7R), package dimensions (2225 / 5763 Metric), and operating temperature range (-55°C to 125°C). The higher voltage rating (2500V vs. 1500V) does not create compatibility issues in circuits designed for 1500V operation.

Q: Are there physical footprint differences between these parts?

A: No. Both parts use the 2225 (5763 Metric) package with identical dimensions: 5.72mm length × 6.35mm width × 2.54mm maximum thickness. PCB layouts require no modification.

Q: What is the difference in packaging between these parts?

A: The main part (2225SC223KAT3A) uses standard packaging, while the substitute (2225WC223KAT1A) is supplied in Tape & Reel (TR) format. Both formats are compatible with standard pick-and-place assembly equipment.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.24.0020. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Which part should be selected for new designs?

A: For new designs, the 2225WC223KAT1A is recommended due to its higher voltage rating providing greater design margin, improved inventory availability, and identical electrical and mechanical characteristics. This selection reduces the risk of voltage stress-related failures in high-voltage applications.
