KYOCERA AVX 2225AC103MAT3A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 2225AC103MAT3A is a 10000 pF (10 nF) ceramic capacitor rated for 1000V (1kV) with X7R temperature coefficient, housed in a 2225 (5763 Metric) surface mount package. This component is classified as Active product status and is designed for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. Substitute parts are identified when equivalent capacitance and package dimensions are maintained while voltage ratings or tolerance specifications may be upgraded to meet enhanced circuit requirements or inventory availability constraints.

Substitute Part Grouping Explanation

Substitute parts for the 2225AC103MAT3A are qualified based on the following criteria:

Maintained Parameters (Required for Substitution):

• Capacitance: 10000 pF (exact match)
• Temperature Coefficient: X7R (identical thermal stability)
• Package / Case: 2225 (5763 Metric) (identical footprint and mounting)
• Mounting Type: Surface Mount, MLCC (identical assembly compatibility)
• Physical Dimensions: 0.225" L × 0.250" W (5.72mm × 6.35mm) (identical PCB placement)
• Thickness (Max): 0.100" (2.54mm) (identical height clearance)
• Operating Temperature Range: -55°C to 125°C (identical thermal performance)
• RoHS Status: ROHS3 Compliant (identical regulatory compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (identical handling requirements)

Allowable Variations (Upgrade Parameters):

• Voltage Rating: May be increased above 1000V (provides enhanced voltage margin)
• Tolerance: May be tightened from ±20% to ±10% (provides improved capacitance accuracy)

The identified substitute parts 2225GC103KAT1A and 2225HC103KAT1A meet all maintained parameters while offering upgraded voltage ratings of 2000V and 3000V respectively, with improved tolerance specifications of ±10%.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2225AC103MAT3A, 2225GC103KAT1A, and 2225HC103KAT1A—maintain Active product status from KYOCERA AVX and are ROHS3 Compliant with REACH Unaffected classification. The substitute parts provide direct functional equivalence with identical mechanical and thermal characteristics.

Selection between these parts depends on circuit voltage requirements:

• 2225AC103MAT3A: Use when circuit design specifies 1000V maximum operating voltage and ±20% capacitance tolerance is acceptable.
• 2225GC103KAT1A: Use when circuit design requires 2000V voltage margin or when ±10% capacitance tolerance is specified.
• 2225HC103KAT1A: Use when circuit design requires 3000V voltage margin or when maximum voltage headroom and ±10% capacitance tolerance are required.

All parts are suitable for direct PCB assembly without design modification due to identical package footprints, mounting types, and physical dimensions.

Frequently Asked Questions (FAQ)

Q: Can 2225GC103KAT1A or 2225HC103KAT1A be used as direct replacements for 2225AC103MAT3A?

A: Yes. Both substitute parts maintain identical capacitance (10000 pF), temperature coefficient (X7R), package dimensions (2225 / 5763 Metric), and operating temperature range (-55°C to 125°C). The substitute parts provide higher voltage ratings (2000V and 3000V respectively) and improved tolerance (±10%), making them functionally compatible for any application designed for the original part.

Q: What is the difference between ±20% and ±10% tolerance?

A: Tolerance specifies the allowable deviation of actual capacitance from the nominal 10000 pF value. The 2225AC103MAT3A allows deviation between 8000 pF and 12000 pF (±20%). The substitute parts 2225GC103KAT1A and 2225HC103KAT1A allow deviation between 9000 pF and 11000 pF (±10%), providing tighter capacitance accuracy for circuits requiring more precise values.

Q: Are there any physical differences between these parts?

A: No. All three parts share identical physical dimensions (0.225" L × 0.250" W / 5.72mm × 6.35mm), thickness (0.100" / 2.54mm), and 2225 package footprint. They are mechanically interchangeable on PCB assemblies without design modification.

Q: What does X7R temperature coefficient mean?

A: X7R indicates the capacitor maintains stable capacitance across the operating temperature range of -55°C to 125°C with a maximum capacitance change of ±15% over this range. All three parts use identical X7R specification, ensuring equivalent thermal performance.

Q: Why would I choose a higher voltage-rated part if my circuit only requires 1000V?

A: Higher voltage-rated parts provide additional safety margin and may offer improved reliability in applications subject to voltage transients or overvoltage conditions. The 2225HC103KAT1A (3000V rating) offers maximum voltage headroom while maintaining identical physical and electrical characteristics for the 10000 pF capacitance value.

Q: Are all parts RoHS compliant?

A: Yes. All three parts—2225AC103MAT3A, 2225GC103KAT1A, and 2225HC103KAT1A—are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and assembly.
