Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1825AC562KAT1A is based on the following criteria:

Mandatory Matching Parameters:

• Capacitance: 5600 pF
• Tolerance: ±10%
• Temperature Coefficient: X7R
• Mounting Type: Surface Mount, MLCC
• Package / Case: 1825 (4564 Metric)
• Physical Dimensions: 4.50mm L x 6.40mm W x 2.54mm Max Thickness
• Operating Temperature Range: -55°C ~ 125°C

Allowable Variation:

• Voltage Rating: Higher voltage ratings are acceptable substitutes when the circuit design permits. The 1825AC562KAT1A (1kV) may be substituted with higher voltage-rated equivalents in the same package.

The identified substitute part 1825WC562KAT1A maintains all mandatory parameters while providing an upgraded voltage rating of 2500V (2.5kV), making it suitable for applications requiring enhanced voltage margin or higher system voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825AC562KAT1A and 1825WC562KAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on circuit voltage requirements:

• 1825AC562KAT1A is appropriate for applications with maximum system voltages up to 1000V.
• 1825WC562KAT1A is appropriate for applications with maximum system voltages up to 2500V and provides additional voltage margin for designs operating near the 1kV threshold.

Both parts share identical physical dimensions, thermal characteristics, and moisture sensitivity ratings, ensuring direct PCB layout compatibility. The substitute part offers higher voltage capability within the same form factor, making it suitable for designs requiring enhanced reliability margins or operation in higher voltage environments.

Frequently Asked Questions (FAQ)

Q: Can the 1825WC562KAT1A replace the 1825AC562KAT1A in all applications?

A: The 1825WC562KAT1A can replace the 1825AC562KAT1A in any application where the circuit voltage does not exceed 2500V. The higher voltage rating does not negatively impact performance in lower voltage circuits. PCB layout compatibility is maintained due to identical physical dimensions.

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

A: Both parts share identical capacitance (5600 pF), tolerance (±10%), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), and physical dimensions. The only difference is the voltage rating: 1000V versus 2500V.

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

A: X7R indicates that the capacitance change over the operating temperature range of -55°C to 125°C is limited to ±15% of the nominal value at 25°C. This makes X7R capacitors suitable for general purpose applications requiring stable capacitance across wide temperature ranges.

Q: Are both parts suitable for high voltage applications?

A: Yes, both parts are rated for high voltage operation. The 1825AC562KAT1A is rated for 1kV, while the 1825WC562KAT1A is rated for 2.5kV. Selection depends on the specific voltage requirements of the application.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. These parts can be stored indefinitely without special moisture control measures, simplifying inventory management and reducing handling requirements.

Q: Are both parts RoHS compliant?

A: Yes, both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
