Substitute Part Grouping Explanation

Substitution eligibility for the 1825CC473MAT1A is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 0.047 µF (exact match required)
• Package / Case: 1825 (4564 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Temperature Coefficient: X7R (exact match required for thermal stability)
• Operating Temperature Range: -55°C to 125°C (minimum requirement)

Allowable Variation Parameters:

• Voltage Rating: May be equal to or higher than 630V (higher voltage rating provides design margin)
• Tolerance: May be tighter (lower tolerance value) than ±20%
• RoHS and REACH Compliance: Must maintain or exceed current certification level

The substitute part 1825AC473KAT1A qualifies as an equivalent because it maintains all mandatory matching parameters while offering improved voltage rating (1000V vs. 630V) and tighter tolerance (±10% vs. ±20%), both of which are acceptable enhancements for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The 1825AC473KAT1A qualifies as a direct substitute for the 1825CC473MAT1A based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical capacitance (0.047 µF) and temperature coefficient (X7R), ensuring equivalent electrical behavior in circuit operation. The substitute's higher voltage rating (1000V vs. 630V) and tighter tolerance (±10% vs. ±20%) represent design improvements that do not compromise functionality in applications designed for the original 630V specification.

Mechanical Compatibility: Identical package dimensions (1825 / 4564 Metric) and mounting type (Surface Mount, MLCC) ensure direct PCB footprint compatibility without layout modifications.

Compliance and Certification: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, meeting current regulatory and environmental requirements. Both parts are manufactured by KYOCERA AVX and carry Active product status, ensuring supply chain continuity and long-term availability.

Packaging Consideration: The main part is supplied in bulk packaging, while the substitute is available in Tape & Reel (TR) format. Packaging format selection depends on assembly process requirements and volume considerations.

Frequently Asked Questions (FAQ)

Q: Can the 1825AC473KAT1A replace the 1825CC473MAT1A in existing designs?

A: Yes. The substitute maintains identical capacitance, package dimensions, and temperature coefficient. The higher voltage rating and tighter tolerance represent design improvements compatible with applications specified for 630V operation.

Q: What is the significance of the voltage rating difference (630V vs. 1000V)?

A: The substitute's 1000V rating provides additional voltage margin in the circuit. For applications designed to operate at 630V, the higher-rated component offers enhanced reliability without requiring circuit redesign. The capacitor will function identically at the original 630V specification.

Q: Are there any thermal performance differences between these parts?

A: No. Both parts feature X7R temperature coefficient and identical -55°C to 125°C operating range, ensuring equivalent thermal stability and performance across the full operating temperature spectrum.

Q: Does the tolerance difference (±20% vs. ±10%) affect circuit performance?

A: The substitute's tighter ±10% tolerance provides improved capacitance accuracy compared to the original ±20% specification. This represents an enhancement that does not negatively impact circuit compatibility. Applications tolerant of ±20% variation will function identically with ±10% tolerance.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1825CC473MAT1A and 1825AC473KAT1A are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the difference between bulk packaging and Tape & Reel format?

A: The main part is supplied in bulk packaging suitable for manual handling and smaller volume applications. The substitute is available in Tape & Reel (TR) format, optimized for automated assembly processes and higher-volume production. Selection depends on assembly methodology and production volume requirements.

Q: Can the 1825AC473KAT1A be used in high-temperature applications?

A: Yes. Both parts maintain identical operating temperature range (-55°C to 125°C) and X7R temperature coefficient, ensuring equivalent performance in high-temperature environments within the specified range.
