KYOCERA AVX 2225AC103MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 2225AC103MAT1A 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 suitable for general-purpose high-voltage applications. Substitute parts are identified when equivalent electrical performance is required, higher voltage ratings are needed for design margin, or inventory constraints necessitate alternative sourcing from the same manufacturer within the same package family.

Substitute Part Grouping Explanation

Substitute parts for the 2225AC103MAT1A are qualified based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 10000 pF (exact match required)
• Temperature Coefficient: X7R (maintains temperature stability across operating range)
• Mounting Type: Surface Mount, MLCC (ensures PCB assembly compatibility)
• Package / Case: 2225 (5763 Metric) (guarantees footprint and land pattern compatibility)
• Physical Dimensions: 0.225" L × 0.250" W and 0.100" max thickness (ensures mechanical fit)
• Operating Temperature Range: -55°C to 125°C (maintains thermal performance envelope)
• Manufacturer: KYOCERA AVX (ensures consistent quality and supply chain reliability)

Allowable Variation Parameters:

• Voltage Rating: May be increased above 1000V (provides design margin and higher reliability)
• Tolerance: May be tightened from ±20% to ±10% (improves circuit precision)
• Packaging Format: May vary between standard and Tape & Reel (TR) formats (does not affect electrical performance)

The substitute parts 2225GC103KAT1A and 2225HC103KAT1A meet all mandatory criteria while offering enhanced voltage ratings of 2kV and 3kV respectively, with improved tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2225AC103MAT1A, 2225GC103KAT1A, and 2225HC103KAT1A—maintain Active product status and full compliance with ROHS3 and REACH regulations. Selection between these parts depends on circuit voltage requirements:

• 2225AC103MAT1A: Use when circuit design specifies 1000V maximum operating voltage and ±20% tolerance is acceptable.
• 2225GC103KAT1A: Use when 2000V voltage rating is required or when improved ±10% tolerance is needed for circuit precision, with 2kV design margin.
• 2225HC103KAT1A: Use when 3000V voltage rating is required or when maximum design margin and ±10% tolerance are specified, with 3kV capability.

All substitute parts are manufactured by KYOCERA AVX, ensuring consistent quality standards, identical footprint compatibility, and equivalent thermal performance across the -55°C to 125°C operating range. Moisture sensitivity level remains at MSL 1 (Unlimited) for all variants, eliminating moisture-related handling constraints.

Frequently Asked Questions (FAQ)

Q: Can 2225GC103KAT1A or 2225HC103KAT1A be used as direct replacements for 2225AC103MAT1A?

A: Yes. Both substitute parts are direct replacements from an electrical and mechanical standpoint. They share identical capacitance (10000 pF), temperature coefficient (X7R), package dimensions (2225 / 5763 Metric), and operating temperature range (-55°C to 125°C). The higher voltage ratings (2kV and 3kV) are compatible with circuits designed for 1kV operation.

Q: What is the difference between the tolerance specifications?

A: The main part 2225AC103MAT1A has ±20% tolerance, while both substitute parts have ±10% tolerance. Tighter tolerance does not affect backward compatibility; it only improves capacitance accuracy for precision-critical applications.

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts use the 2225 (5763 Metric) package with dimensions of 0.225" L × 0.250" W (5.72mm × 6.35mm) and maximum thickness of 0.100" (2.54mm). PCB footprints and land patterns are identical.

Q: What is the significance of the X7R temperature coefficient?

A: X7R indicates a ceramic capacitor with stable capacitance across the operating temperature range of -55°C to 125°C. All three parts maintain this specification, ensuring consistent performance in thermal cycling environments.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All three parts are ROHS3 Compliant, REACH Unaffected, and maintain MSL 1 (Unlimited) moisture sensitivity level. Regulatory and environmental compliance is identical across all variants.

Q: Which part should be selected for maximum design margin?

A: The 2225HC103KAT1A offers the highest voltage rating at 3000V (3kV), providing maximum design margin above the 1000V specification of the original part. This part also features ±10% tolerance for improved capacitance accuracy.

Q: Is packaging format (standard vs. Tape & Reel) a consideration for substitution?

A: Packaging format does not affect electrical or mechanical compatibility. Both standard and Tape & Reel (TR) formats contain identical components and are suitable for automated assembly processes.
