1825CC103MAT3A Ceramic Capacitor: Equivalent & Substitute Parts

Part Overview

The 1825CC103MAT3A is a 10000 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX in the 1825 (4564 Metric) surface-mount package. This X7R temperature coefficient capacitor operates across -55°C to 125°C and is rated for 630V applications. The part is currently active in production with 945 units in stock. Substitute parts are identified when identical capacitance and package specifications are maintained while voltage ratings are increased, enabling use in higher-voltage circuit designs without physical redesign.

Substitute Part Grouping Explanation

Substitute parts for the 1825CC103MAT3A are qualified based on the following criteria:

• Identical Capacitance: All substitutes maintain 10000 pF capacitance value
• Identical Package: All substitutes use the 1825 (4564 Metric) surface-mount package with matching physical dimensions (4.50mm x 6.40mm x 2.54mm max thickness)
• Identical Temperature Coefficient: All substitutes maintain X7R temperature coefficient and -55°C to 125°C operating range
• Identical Mounting Type: All substitutes are surface-mount MLCC components
• Voltage Rating Variation: Substitute parts feature increased voltage ratings (1500V, 2000V, or 3000V) compared to the base 630V rating
• Tolerance Variation: Substitute parts feature ±10% tolerance compared to the base ±20% tolerance
• Compliance Equivalence: All substitutes maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status

The voltage rating increase allows these parts to function in applications requiring higher voltage withstand capability while maintaining identical physical footprint and electrical performance characteristics at the original 630V operating point.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full compliance with ROHS3 and REACH requirements. Selection between the base part 1825CC103MAT3A and its substitutes depends on circuit voltage requirements:

• 1825CC103MAT3A (630V): Use when circuit maximum voltage does not exceed 630V and ±20% tolerance is acceptable
• 1825SC103KAT1A (1500V): Use for circuits requiring voltage rating up to 1500V with improved ±10% tolerance
• 1825GC103KAT1A (2000V): Use for circuits requiring voltage rating up to 2000V with improved ±10% tolerance
• 1825HC103KAT1A (3000V): Use for circuits requiring voltage rating up to 3000V with improved ±10% tolerance

All parts share identical physical footprint, capacitance value, temperature coefficient, and operating temperature range. Substitution does not require PCB redesign. The improved tolerance specification (±10% vs ±20%) in substitute parts provides tighter capacitance control for applications where precision is required.

Frequently Asked Questions (FAQ)

Q: Can 1825CC103MAT3A be replaced with a higher-voltage substitute in a 630V circuit?

A: Yes. All substitute parts (1825SC103KAT1A, 1825GC103KAT1A, 1825HC103KAT1A) are rated for voltages exceeding 630V and function correctly in 630V applications. Higher voltage rating provides additional safety margin without affecting circuit performance.

Q: Are the physical dimensions identical across all parts?

A: Yes. All parts use the 1825 (4564 Metric) package with dimensions 4.50mm x 6.40mm x 2.54mm (max thickness). No PCB layout changes are required when substituting between these parts.

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

A: Tolerance specifies the allowable deviation from the nominal 10000 pF capacitance value. ±20% allows deviation from 8000 pF to 12000 pF. ±10% allows deviation from 9000 pF to 11000 pF. The ±10% tolerance in substitute parts provides tighter capacitance control for precision applications.

Q: Do all parts have the same temperature coefficient?

A: Yes. All parts feature X7R temperature coefficient with operating range -55°C to 125°C, ensuring stable capacitance performance across the full temperature range.

Q: Are packaging options different between parts?

A: The base part 1825CC103MAT3A is supplied without specified packaging. All substitute parts are supplied in Tape & Reel (TR) packaging. Verify packaging requirements for your procurement process.

Q: Do all parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring equivalent environmental and regulatory compliance.
