KYOCERA AVX 1825AC103MAT9A Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825AC103MAT9A is a 10000 pF ceramic capacitor rated at 1000V (1kV) with X7R temperature coefficient, designed for general-purpose high-voltage applications. This surface-mount multilayer ceramic capacitor (MLCC) in 1825 (4564 Metric) package is actively produced and ROHS3 compliant. Substitute parts are identified when circuit requirements demand higher voltage ratings, improved tolerance specifications, or enhanced reliability margins while maintaining identical capacitance values and physical form factors.

Substitute Part Grouping Explanation

Substitute parts for the 1825AC103MAT9A are qualified based on the following criteria:

• Identical capacitance value: 10000 pF
• Identical package and form factor: 1825 (4564 Metric)
• Identical physical dimensions: 4.50mm × 6.40mm × 2.54mm maximum thickness
• Identical temperature coefficient: X7R
• Identical operating temperature range: -55°C to 125°C
• Identical mounting type: Surface Mount, MLCC
• Identical moisture sensitivity level: MSL 1
• Identical compliance certifications: ROHS3, REACH Unaffected, EAR99

Substitutes are differentiated by higher voltage ratings and improved tolerance specifications, which provide enhanced design margins and reliability without affecting circuit board layout or assembly processes.

Parameter Comparison

Engineering Selection Recommendations

All three parts are actively produced by KYOCERA AVX and maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Selection between the main part and substitutes depends on circuit voltage requirements:

• 1825AC103MAT9A: Use when circuit design specifies 1000V maximum operating voltage and ±20% tolerance is acceptable.
• 1825GC103KAT1A: Use when circuit design requires 2000V voltage rating or when ±10% tolerance specification is mandated.
• 1825HC103KAT1A: Use when circuit design requires 3000V voltage rating or when maximum voltage margin and ±10% tolerance are required.

All parts share identical physical footprints, assembly compatibility, and environmental performance characteristics, enabling direct substitution at the component level without circuit board redesign.

Frequently Asked Questions (FAQ)

Q: Can 1825GC103KAT1A or 1825HC103KAT1A be used as direct replacements for 1825AC103MAT9A?

A: Yes. Both substitute parts maintain identical capacitance (10000 pF), package dimensions (1825 / 4564 Metric), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and mounting type (Surface Mount, MLCC). They are physically and electrically interchangeable at the board level.

Q: What is the primary difference between these parts?

A: The main differences are voltage rating and tolerance. The 1825AC103MAT9A is rated at 1000V with ±20% tolerance. The 1825GC103KAT1A is rated at 2000V with ±10% tolerance. The 1825HC103KAT1A is rated at 3000V with ±10% tolerance. Higher voltage ratings provide greater design margin in high-voltage applications.

Q: Are there any packaging differences?

A: The main part (1825AC103MAT9A) is supplied in standard packaging. The substitute parts (1825GC103KAT1A and 1825HC103KAT1A) are supplied in Tape & Reel (TR) format. Both packaging formats are compatible with automated assembly equipment.

Q: Do all parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Moisture sensitivity level is MSL 1 (Unlimited) for all parts.

Q: Which substitute should be selected for maximum reliability?

A: Selection is based on circuit voltage requirements, not reliability assumptions. The 1825HC103KAT1A provides the highest voltage rating (3000V) and tighter tolerance (±10%), suitable for applications requiring maximum voltage margin. The 1825GC103KAT1A provides intermediate voltage rating (2000V) and tolerance (±10%). Choose based on your circuit's specified voltage and tolerance requirements.
