1825GC103MAT3A Equivalent & Substitute Parts

Part Overview

The 1825GC103MAT3A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 10000 pF, rated voltage of 2000V (2kV), 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 a wide operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Equivalent and substitute parts are identified to provide design flexibility, accommodate supply chain variations, or meet specific tolerance and voltage requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1825GC103MAT3A is determined by the following critical parameters: capacitance value (10000 pF), temperature coefficient (X7R), package type (1825 / 4564 Metric), mounting method (surface mount MLCC), and operating temperature range (-55°C ~ 125°C). All substitute parts must maintain identical capacitance, package dimensions, and temperature performance characteristics.

The identified substitute parts differ in two allowed parameters:

Tolerance Enhancement: The 1825GC103KAT1A provides tighter tolerance (±10% versus ±20%), enabling use in applications requiring higher capacitance accuracy while maintaining all other electrical and mechanical specifications.

Voltage Rating Upgrade: The 1825HC103KAT1A provides higher voltage rating (3000V versus 2000V), enabling use in applications with elevated voltage requirements while maintaining identical capacitance, tolerance, package, and temperature characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts—1825GC103MAT3A, 1825GC103KAT1A, and 1825HC103KAT1A—are active production components from KYOCERA AVX with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on application-specific requirements:

1825GC103MAT3A is suitable for general-purpose applications where ±20% capacitance tolerance is acceptable and the 2000V rating meets circuit voltage requirements.

1825GC103KAT1A is suitable for applications requiring tighter capacitance tolerance (±10%) while operating at 2000V. This part provides improved accuracy for circuits sensitive to capacitance variation.

1825HC103KAT1A is suitable for applications requiring operation at elevated voltages up to 3000V. This part provides voltage margin for high-voltage circuit designs while maintaining ±10% tolerance and identical package footprint.

All parts share identical physical dimensions, thermal characteristics, and compliance certifications, ensuring direct substitution within the specified parameter constraints.

Frequently Asked Questions (FAQ)
