KYOCERA AVX 1825SC103MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825SC103MAT1A is a high-voltage ceramic capacitor rated at 10000 pF with 1500V (1.5kV) operating voltage and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1825 (4564 Metric) package is designed for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating temperature range. The part is currently active in production with 699 pieces available in stock. Equivalent and substitute parts are identified based on matching capacitance value, package size, mounting type, and voltage rating compatibility within the KYOCERA AVX product line.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825SC103MAT1A are identified based on the following criteria:

Matching Parameters (Required for Substitution):

• Capacitance value: 10000 pF
• Package / Case: 1825 (4564 Metric)
• Mounting type: Surface Mount, MLCC
• Temperature coefficient: X7R
• Operating temperature range: -55°C to 125°C
• Physical dimensions: 4.50mm L × 6.40mm W × 2.54mm Max Thickness
• Compliance: ROHS3 Compliant, REACH Unaffected
• Moisture sensitivity: MSL 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Voltage rating (1500V, 2000V, or 3000V)
• Tolerance (±20% or ±10%)
• Packaging format (bulk or Tape & Reel)

The 1825SC103MAT1A can be substituted with higher voltage-rated alternatives (1825GC103KAT1A at 2000V or 1825HC103KAT1A at 3000V) in applications where increased voltage margin is beneficial. The 1825SC103KAT1A provides the same voltage rating with improved tolerance (±10% versus ±20%).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full ROHS3 compliance with REACH unaffected designation, ensuring regulatory continuity in production environments.

1825GC103KAT1A (2000V Rating): Suitable for applications requiring increased voltage margin above the 1500V specification. Offers ±10% tolerance improvement and higher inventory availability (2400 pieces).

1825HC103KAT1A (3000V Rating): Appropriate for high-voltage applications or designs requiring maximum voltage safety margin. Provides ±10% tolerance and the highest inventory availability (25145 pieces) among all options.

1825SC103KAT1A (1500V Rating, ±10% Tolerance): Direct functional equivalent with identical voltage rating but superior tolerance specification (±10% versus ±20%). Recommended for applications where tighter capacitance tolerance is required without voltage rating changes.

All substitute parts are packaged in Tape & Reel format and maintain identical physical dimensions, thermal characteristics, and moisture sensitivity ratings as the main part.

Frequently Asked Questions (FAQ)

Q: Can the 1825SC103MAT1A be replaced with a higher voltage-rated part?

A: Yes. The 1825GC103KAT1A (2000V) and 1825HC103KAT1A (3000V) are direct substitutes with identical capacitance, package size, and thermal characteristics. Higher voltage ratings provide additional safety margin in the circuit without affecting form factor or mounting compatibility.

Q: What is the difference between the 1825SC103MAT1A and 1825SC103KAT1A?

A: Both parts share identical voltage rating (1500V), capacitance (10000 pF), and package specifications. The primary difference is tolerance: the MAT1A variant has ±20% tolerance, while the KAT1A variant has ±10% tolerance. The KAT1A also uses Tape & Reel packaging versus bulk packaging for the MAT1A.

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

A: Yes. All listed parts use the 1825 (4564 Metric) package with identical physical dimensions (4.50mm L × 6.40mm W × 2.54mm Max thickness), ensuring direct PCB footprint compatibility without layout modifications.

Q: Do substitute parts require different soldering or handling procedures?

A: No. All parts maintain MSL 1 (Unlimited) moisture sensitivity rating and identical surface-mount MLCC mounting type, requiring no changes to assembly, soldering, or storage procedures.

Q: Which substitute part offers the best inventory availability?

A: The 1825HC103KAT1A (3000V rating) has the highest inventory availability at 25145 pieces, followed by the 1825GC103KAT1A (2000V) at 2400 pieces.
