KYOCERA AVX 1825GC103MAT3A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825GC103MAT3A is a high-voltage ceramic capacitor with 10000 pF capacitance rated at 2000V (2kV), featuring X7R temperature coefficient and 1825 (4564 Metric) package dimensions. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable performance across the -55°C to 125°C operating temperature range. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical performance can be maintained within the specified parameter tolerances while meeting application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825GC103MAT3A are qualified based on the following criteria:

Core Electrical Parameters (Must Match):

• Capacitance value: 10000 pF
• Temperature coefficient: X7R
• Package / Case: 1825 (4564 Metric)
• Mounting type: Surface Mount, MLCC
• Operating temperature range: -55°C to 125°C

Allowable Variations:

• Tolerance: Tighter tolerance (±10%) is acceptable as a substitute for ±20%
• Voltage rating: Equal or higher voltage rating is acceptable as a substitute for 2000V (2kV)
• Packaging format: Tape & Reel (TR) is compatible with the original bulk packaging

Identified Substitutes:

1. 1825GC103KAT1A – Same voltage rating (2000V) with improved tolerance (±10% vs ±20%)
2. 1825HC103KAT1A – Higher voltage rating (3000V vs 2000V) with improved tolerance (±10% vs ±20%)

Both substitutes maintain identical capacitance, package dimensions, temperature coefficient, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

1825GC103KAT1A Selection Criteria:

• Direct electrical equivalent with identical voltage rating (2000V)
• Improved capacitance tolerance (±10%) provides tighter performance specification
• Tape & Reel packaging suitable for automated assembly processes
• All compliance certifications maintained (ROHS3, REACH Unaffected, EAR99)
• Recommended when tolerance improvement is required without voltage derating

1825HC103KAT1A Selection Criteria:

• Voltage rating upgrade (3000V vs 2000V) provides additional safety margin
• Improved capacitance tolerance (±10%) with higher voltage capability
• Tape & Reel packaging suitable for automated assembly processes
• All compliance certifications maintained (ROHS3, REACH Unaffected, EAR99)
• Recommended for applications requiring higher voltage headroom or when design margin enhancement is necessary

Both substitutes maintain active production status and full regulatory compliance with the original part.

Frequently Asked Questions (FAQ)

Q: Can 1825GC103KAT1A be used as a direct replacement for 1825GC103MAT3A?

A: Yes. Both parts share identical capacitance (10000 pF), voltage rating (2000V), temperature coefficient (X7R), package dimensions (1825/4564 Metric), and operating temperature range (-55°C to 125°C). The substitute features improved tolerance (±10% vs ±20%), making it functionally equivalent or superior for the same application.

Q: What is the advantage of 1825HC103KAT1A over the main part?

A: The 1825HC103KAT1A provides a higher voltage rating (3000V vs 2000V) while maintaining the same capacitance and package size. This allows operation at higher voltage levels or provides additional design margin in existing 2000V applications. Capacitance tolerance is also improved to ±10%.

Q: Are there physical compatibility issues when substituting these parts?

A: No. All three parts use identical 1825 (4564 Metric) package dimensions: 4.50mm length × 6.40mm width × 2.54mm maximum thickness. They are mechanically and electrically interchangeable on the same PCB footprint.

Q: Does packaging format affect part selection?

A: The main part (1825GC103MAT3A) is supplied in bulk packaging, while both substitutes (1825GC103KAT1A and 1825HC103KAT1A) are supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes. Bulk-to-TR conversion does not affect electrical performance or compliance status.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts are ROHS3 compliant with REACH Unaffected status and EAR99 ECCN classification. Regulatory compliance is maintained across all substitutions.

Q: Which substitute should be selected for new designs?

A: For new designs, 1825GC103KAT1A is recommended as the baseline substitute, offering improved tolerance with identical electrical specifications. If higher voltage margin is required, 1825HC103KAT1A provides 3000V rating in the same package footprint.
