KYOCERA AVX 1825AC103MAT3A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825AC103MAT3A is a 10000 pF high-voltage ceramic capacitor rated at 1000V (1kV) with X7R temperature coefficient, housed in a 1825 (4564 Metric) surface-mount package. This component is Active status and ROHS3 compliant, 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 to address applications requiring higher voltage ratings or improved tolerance specifications while maintaining identical physical dimensions and core electrical characteristics.

• Package / Case: 1825 (4564 Metric) (identical physical footprint)
• Temperature Coefficient: X7R (identical)
• Operating Temperature Range: -55°C to 125°C (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• Size / Dimension: 0.177" L x 0.252" W (4.50mm x 6.40mm) (identical)
• Thickness (Max): 0.100" (2.54mm) (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
• Manufacturer: KYOCERA AVX (identical)

Variable Parameters (Substitution Basis):

• Voltage - Rated: 1000V, 1500V, 2000V, or 3000V
• Tolerance: ±20% or ±10%

All substitute parts maintain identical physical dimensions, thermal characteristics, and compliance certifications, enabling direct board-level substitution. Voltage rating and tolerance variations allow selection based on circuit requirements and design margins.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring long-term availability and regulatory conformance. Selection between the 1825AC103MAT3A and substitute variants depends on circuit voltage requirements:

• 1825AC103MAT3A (1000V): Baseline selection for applications with 1000V maximum operating voltage and tolerance requirements of ±20%.

• 1825SC103KAT1A (1500V): Suitable for circuits requiring 1500V rating with improved ±10% tolerance specification.

• 1825GC103KAT1A (2000V): Applicable for designs with 2000V voltage margin requirements and ±10% tolerance.

• 1825HC103KAT1A (3000V): Specified for high-voltage applications requiring 3000V rating with ±10% tolerance and maximum design margin.

All parts share identical physical footprints, thermal performance, and compliance certifications, enabling direct substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 1825AC103MAT3A with a higher-voltage-rated part?

A: Yes. The 1825SC103KAT1A (1500V), 1825GC103KAT1A (2000V), and 1825HC103KAT1A (3000V) are direct substitutes with identical physical dimensions, package footprint, and thermal characteristics. Higher voltage ratings provide additional design margin without affecting board layout.

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

A: The 1825AC103MAT3A carries ±20% tolerance, while all substitute parts carry ±10% tolerance. The ±10% specification provides tighter capacitance control, beneficial for circuits with strict capacitance requirements. Both tolerances are within the X7R temperature coefficient specification.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All parts use the 1825 (4564 Metric) package with identical dimensions of 0.177" L x 0.252" W (4.50mm x 6.40mm) and maximum thickness of 0.100" (2.54mm). No PCB redesign is required for substitution.

Q: Do substitute parts have the same moisture sensitivity level?

A: Yes. All parts, including the 1825AC103MAT3A and all substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.

Q: Are all parts ROHS3 compliant?

A: Yes. The 1825AC103MAT3A and all substitute parts are ROHS3 compliant, meeting regulatory requirements for restricted substances.
