2225SC223MAT9A Equivalent & Substitute Parts

Part Overview

The 2225SC223MAT9A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 0.022 µF with 1500V (1.5kV) voltage rating and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide 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), making it suitable for industrial and commercial applications. Equivalent and substitute parts are identified based on matching capacitance value, package form factor, and temperature coefficient while allowing for variations in voltage rating and tolerance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 2225SC223MAT9A is determined by the following critical parameters:

• Capacitance Value: Must remain 0.022 µF (no deviation permitted)
• Package Form Factor: Must be 2225 (5763 Metric) to ensure PCB footprint compatibility
• Temperature Coefficient: Must be X7R to maintain stable capacitance performance across the operating temperature range
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C minimum

Substitute parts may vary in:

• Voltage Rating: Higher voltage ratings provide enhanced safety margin and are acceptable substitutes
• Tolerance: Tighter tolerance specifications (e.g., ±10% vs. ±20%) are acceptable upgrades
• Packaging Format: Different packaging configurations (e.g., Tape & Reel vs. bulk) do not affect electrical compatibility

Parameter Comparison

Engineering Selection Recommendations

The 2225WC223KAT1A qualifies as a direct substitute for the 2225SC223MAT9A based on the following engineering criteria:

• Both parts maintain identical capacitance value (0.022 µF) and package form factor (2225 / 5763 Metric)
• Both employ X7R temperature coefficient, ensuring equivalent capacitance stability across the -55°C to 125°C operating range
• The substitute part features a higher voltage rating (2500V vs. 1500V), providing increased voltage margin without affecting circuit performance in applications rated for 1500V operation
• The substitute part offers improved tolerance specification (±10% vs. ±20%), resulting in tighter capacitance control
• Both parts are ROHS3 compliant with MSL 1 rating, meeting identical environmental and regulatory requirements
• Both parts are manufactured by KYOCERA AVX and maintain active production status

The 2225WC223KAT1A is suitable for direct replacement in any application originally specified for the 2225SC223MAT9A.

Frequently Asked Questions (FAQ)

Q: Can the 2225WC223KAT1A replace the 2225SC223MAT9A in my circuit?

A: Yes. The substitute part maintains the same capacitance value (0.022 µF), temperature coefficient (X7R), package form factor (2225), and operating temperature range (-55°C ~ 125°C). The higher voltage rating (2500V) and tighter tolerance (±10%) represent improvements over the original specification.

Q: What is the difference between the voltage ratings of these two parts?

A: The main part is rated for 1500V (1.5kV), while the substitute is rated for 2500V (2.5kV). In applications operating at or below 1500V, the higher voltage rating of the substitute part provides additional safety margin without affecting electrical performance.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 2225 (5763 Metric) package with identical dimensions: 5.72mm length, 6.35mm width, and 2.54mm maximum thickness. PCB footprints are interchangeable.

Q: Does the tolerance difference affect circuit performance?

A: The substitute part features ±10% tolerance compared to the main part's ±20% tolerance. This tighter tolerance specification results in more consistent capacitance values across production batches, which may improve circuit performance in applications sensitive to capacitance variation.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2225SC223MAT9A and 2225WC223KAT1A are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), meeting identical environmental and regulatory standards.

Q: What packaging formats are available?

A: The main part is available in standard packaging, while the substitute part is available in Tape & Reel (TR) format. Both formats contain identical electrical components; packaging format selection depends on assembly process requirements.
