Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825CC473MAT9A is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 0.047 µF (exact match required)
• Package / Case: 1825 (4564 Metric) (physical compatibility required)
• Temperature Coefficient: X7R (thermal stability requirement)
• Mounting Type: Surface Mount, MLCC (assembly compatibility required)

Allowable Variation Parameters:

• Voltage Rating: May be equal to or greater than 630V (uprating acceptable)
• Tolerance: May be tighter than ±20% (±10% acceptable as improvement)
• RoHS and REACH compliance status (regulatory equivalence)

The substitute part 1825AC473KAT1A meets all mandatory matching criteria while providing improved voltage rating (1000V vs 630V) and tighter tolerance (±10% vs ±20%).

Parameter Comparison

Engineering Selection Recommendations

Both the 1825CC473MAT9A and 1825AC473KAT1A are active production parts manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. The 1825AC473KAT1A provides enhanced specifications through higher voltage rating (1000V vs 630V) and improved tolerance (±10% vs ±20%) while maintaining identical physical package dimensions and thermal characteristics. Selection between these parts should be based on application voltage requirements and tolerance specifications. The substitute part is suitable for applications requiring higher voltage margin or tighter capacitance tolerance within the same form factor.

Frequently Asked Questions (FAQ)

Q: Can 1825AC473KAT1A replace 1825CC473MAT9A in all applications?

A: Yes, provided the application circuit can accommodate the higher voltage rating (1000V vs 630V). The substitute part maintains identical capacitance, package dimensions, temperature coefficient, and operating temperature range. The tighter tolerance (±10%) is an improvement over the original specification (±20%).

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the 1825 (4564 Metric) package with dimensions of 4.50mm length, 6.40mm width, and 2.54mm maximum thickness. They are mechanically interchangeable on PCB assemblies.

Q: What is the significance of the X7R temperature coefficient?

A: X7R indicates a temperature coefficient of ±15% over the operating range of -55°C to 125°C. This specification is identical for both parts and ensures stable capacitance performance across the full operating temperature range.

Q: Does the packaging format differ between these parts?

A: The main part 1825CC473MAT9A is specified with standard packaging, while the substitute 1825AC473KAT1A is supplied in Tape & Reel (TR) format. Both are surface mount components suitable for automated assembly processes.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and use.
