2225SC223KAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 2225SC223KAT1A is a 0.022 µF ceramic capacitor rated for 1500V (1.5kV) operation with X7R temperature coefficient characteristics. Manufactured by KYOCERA AVX, this surface mount multilayer ceramic capacitor (MLCC) is designed for general-purpose high-voltage applications. The part maintains active product status with 638 units currently in stock. Substitute parts are identified when design requirements permit higher voltage ratings or when inventory constraints necessitate alternative sourcing while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2225SC223KAT1A 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. standard packaging)
• Inventory availability: Does not affect electrical compatibility

The 2225WC223KAT1A qualifies as a direct substitute because it maintains all mandatory parameters while offering an upgraded voltage rating of 2500V (2.5kV), providing enhanced design margin for high-voltage applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 2225SC223KAT1A and 2225WC223KAT1A are active products manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on circuit voltage requirements:

• 2225SC223KAT1A: Select when circuit design specifies 1500V maximum operating voltage and inventory availability is adequate.
• 2225WC223KAT1A: Select when circuit design permits 2500V rated components, when higher voltage margin is required for reliability, or when the higher inventory level (2585 units) supports supply chain continuity.

Both parts are electrically and mechanically interchangeable within their respective voltage specifications. The substitute part provides additional voltage headroom without altering capacitance, tolerance, temperature characteristics, or physical form factor.

Frequently Asked Questions (FAQ)

Q: Can 2225WC223KAT1A replace 2225SC223KAT1A in all applications?

A: Yes, provided the circuit design permits operation with a 2500V rated component. The substitute part maintains identical capacitance (0.022 µF), tolerance (±10%), temperature coefficient (X7R), package dimensions (2225), and thermal operating range (-55°C to 125°C). The higher voltage rating does not degrade performance in lower-voltage applications.

Q: What is the physical difference between these parts?

A: There is no physical difference. Both parts use the 2225 (5763 Metric) package with identical dimensions: 5.72mm length, 6.35mm width, and 2.54mm maximum thickness. They are mechanically interchangeable on PCB layouts.

Q: Are there packaging format differences?

A: The 2225SC223KAT1A uses standard packaging, while the 2225WC223KAT1A is supplied in Tape & Reel (TR) format. This affects handling and assembly processes but does not impact electrical performance or component compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture handling requirements.

Q: Which part should be selected for new designs?

A: For new designs, the 2225WC223KAT1A is preferred when voltage specifications allow, as it provides enhanced design margin and superior inventory availability (2585 units vs. 638 units). Both parts carry active product status with no planned obsolescence.
