Equivalent & Substitute Parts for 2225WC103MAT1A

Part Overview

The 2225WC103MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 10000 pF with a 2500V (2.5kV) 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. Alternative equivalent parts may be required due to inventory constraints, design upgrades, or application-specific voltage margin requirements.

Substitute Part Grouping Explanation

The 2225HC103KAT1A qualifies as a direct substitute for the 2225WC103MAT1A based on the following substitution criteria:

Matching Parameters:

• Capacitance: 10000 pF (identical)
• Temperature Coefficient: X7R (identical)
• Operating Temperature Range: -55°C to 125°C (identical)
• Package / Case: 2225 (5763 Metric) (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• Physical Dimensions: 5.72mm L × 6.35mm W × 2.54mm Max Thickness (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

Allowable Variations:

• Tolerance: ±10% (substitute) vs. ±20% (main part) — tighter tolerance is acceptable
• Voltage Rating: 3000V (3kV) (substitute) vs. 2500V (2.5kV) (main part) — higher voltage rating provides additional safety margin and is acceptable for applications rated at or below 2500V

The substitute part maintains identical physical form factor, thermal characteristics, and compliance certifications while offering improved voltage margin and tighter capacitance tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both the 2225WC103MAT1A and 2225HC103KAT1A are active production parts manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on application voltage requirements and tolerance specifications:

• Use 2225WC103MAT1A when the application circuit is designed specifically for 2500V operation and ±20% capacitance tolerance is acceptable.
• Use 2225HC103KAT1A when higher voltage margin is desired (3000V rating provides 20% additional headroom above 2500V), or when tighter capacitance tolerance (±10%) is required for circuit performance.

Both parts are suitable for general-purpose high-voltage applications across the full -55°C to 125°C operating temperature range. The identical physical package and mounting characteristics ensure direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can 2225HC103KAT1A replace 2225WC103MAT1A in existing designs?

A: Yes. The substitute part maintains identical capacitance, package dimensions, mounting type, and thermal characteristics. The higher voltage rating (3000V vs. 2500V) and tighter tolerance (±10% vs. ±20%) are compatible with applications designed for the original part.

Q: What is the significance of the voltage rating difference?

A: The 2225HC103KAT1A is rated for 3000V compared to the 2225WC103MAT1A at 2500V. This 500V difference provides additional safety margin in high-voltage applications. Both parts are suitable for circuits operating at or below 2500V.

Q: Does the tighter tolerance of the substitute part affect compatibility?

A: No. The ±10% tolerance of 2225HC103KAT1A is tighter than the ±20% tolerance of 2225WC103MAT1A. Tighter tolerance is compatible with designs accepting the original part's tolerance specification.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 2225 (5763 Metric) package with identical dimensions of 5.72mm L × 6.35mm W × 2.54mm maximum thickness. No PCB layout changes are required.

Q: What is the packaging difference between these parts?

A: The 2225WC103MAT1A is supplied in standard packaging, while the 2225HC103KAT1A is supplied in Tape & Reel (TR) format. Both are suitable for automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both 2225WC103MAT1A and 2225HC103KAT1A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
