1825AC223MAT1A Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 1825AC223MAT1A is a 0.022 µF ceramic capacitor rated for 1000V (1kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) 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 rating (MSL 1). Equivalent and substitute parts are identified when they maintain identical capacitance and package specifications while offering alternative voltage ratings or tolerance grades suitable for the same circuit applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 1825AC223MAT1A is determined by strict adherence to the following criteria:

Fixed Parameters (Non-Negotiable):

• Capacitance: 0.022 µF
• 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

Variable Parameters (Allowed for Substitution):

• Voltage Rating: May be equal or higher than the original 1000V rating
• Tolerance: May differ from ±20% while maintaining the same capacitance value

The substitute part 1825GC223KAT1A meets all fixed parameters and offers an upgraded voltage rating of 2000V (2kV) with improved tolerance of ±10%, making it suitable for applications requiring higher voltage margin or tighter capacitance tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825AC223MAT1A and 1825GC223KAT1A are active production parts manufactured by KYOCERA AVX with identical RoHS3 compliance and REACH unaffected status. The 1825GC223KAT1A provides a direct substitute with enhanced specifications: the doubled voltage rating of 2000V (2kV) versus 1000V (1kV) and improved tolerance of ±10% versus ±20% offer greater design margin and tighter capacitance control. Both parts share identical package geometry, thermal characteristics, and moisture sensitivity ratings, ensuring mechanical and thermal compatibility in surface-mount applications. Selection between these parts depends on circuit voltage requirements and tolerance specifications rather than physical or environmental constraints.

Frequently Asked Questions (FAQ)

Q: Can the 1825GC223KAT1A replace the 1825AC223MAT1A in existing designs?

A: Yes. The 1825GC223KAT1A is a direct substitute with identical capacitance, package, and thermal characteristics. The higher voltage rating and tighter tolerance represent performance enhancements rather than deviations from the original specification.

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

A: No. Both parts use the identical 1825 (4564 Metric) package with matching dimensions of 4.50mm L × 6.40mm W × 2.54mm maximum thickness. PCB footprints and reflow profiles remain unchanged.

Q: What is the significance of the voltage rating difference?

A: The 1825GC223KAT1A operates at 2000V (2kV) compared to the 1825AC223MAT1A at 1000V (1kV). This doubled rating provides additional safety margin in high-voltage applications and allows operation in circuits with higher voltage stress without derating.

Q: How do the tolerance specifications affect circuit performance?

A: The 1825AC223MAT1A carries ±20% tolerance, while the 1825GC223KAT1A carries ±10% tolerance. Tighter tolerance in the substitute part reduces capacitance variation across production batches, beneficial for applications requiring precise capacitance values.

Q: Are both parts suitable for the full operating temperature range?

A: Yes. Both parts maintain X7R temperature coefficient characteristics across the -55°C to 125°C operating range with identical thermal stability.

Q: What is the moisture sensitivity consideration for these parts?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage practices apply without special desiccant or baking requirements.
