Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825CC473MATME 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)
• Temperature Coefficient: X7R (thermal stability requirement)
• Mounting Type: Surface Mount, MLCC (assembly compatibility)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)

Allowable Variation Parameters:

• Voltage Rating: May be equal to or greater than 630V (uprating acceptable)
• Tolerance: May be tighter than ±20% (±10% acceptable as upgrade)

The identified substitute part 1825AC473KAT1A meets all mandatory matching criteria while providing voltage uprating to 1000V and improved tolerance specification of ±10%.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825CC473MATME and 1825AC473KAT1A are Active products with full ROHS3 compliance and identical MSL 1 ratings. The 1825AC473KAT1A provides a direct functional upgrade with 370V additional voltage margin (1000V vs. 630V) and improved tolerance specification (±10% vs. ±20%), while maintaining identical physical footprint and thermal characteristics. Selection between these parts should be based on circuit voltage requirements and tolerance specifications. The substitute part is suitable for applications requiring higher voltage headroom or tighter capacitance tolerance without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 1825AC473KAT1A replace the 1825CC473MATME in existing designs?

A: Yes. The substitute part maintains identical capacitance, package dimensions, temperature coefficient, and operating temperature range. The higher voltage rating and tighter tolerance represent functional improvements compatible with the original design specifications.

Q: Are there physical compatibility concerns with the 1825AC473KAT1A?

A: No. Both parts use the identical 1825 (4564 Metric) package with matching dimensions of 4.50mm L x 6.40mm W x 2.54mm maximum thickness, ensuring direct PCB footprint compatibility.

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

A: The 1825AC473KAT1A is rated for 1000V compared to the 1825CC473MATME at 630V. This represents a voltage uprating that provides additional safety margin in high-voltage applications. The substitute part is suitable for any application requiring 630V or less.

Q: How do the tolerance specifications differ?
