KYOCERA AVX 1825CC473MAT3A\SB Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825CC473MAT3A\SB is an active, high-voltage ceramic capacitor rated at 0.047 µF with 630V operating voltage and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating range. Finding equivalent or substitute parts may be necessary due to inventory constraints, lead time requirements, or application-specific performance needs while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825CC473MAT3A\SB is determined by the following critical parameters:

• Capacitance Value: Must be 0.047 µF (exact match required)
• Package / Case: Must be 1825 (4564 Metric) for mechanical and PCB compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Temperature Coefficient: Must be X7R for thermal stability equivalence
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Voltage Rating: Must be equal to or greater than 630V
• Tolerance: May vary; tighter tolerance (±10%) is acceptable as an upgrade
• Compliance: RoHS3 and REACH status must be maintained

The substitute part 1825AC473KAT1A meets all substitution criteria. It maintains identical capacitance, package, mounting type, and temperature coefficient while providing upgraded voltage rating (1000V vs. 630V) and improved tolerance (±10% vs. ±20%).

Parameter Comparison

Engineering Selection Recommendations

Both the 1825CC473MAT3A\SB and 1825AC473KAT1A are active products from KYOCERA AVX with full RoHS3 compliance and REACH unaffected status. The substitute part 1825AC473KAT1A provides performance enhancements through higher voltage rating (1000V vs. 630V) and tighter capacitance tolerance (±10% vs. ±20%), making it suitable for applications requiring greater voltage margin or improved capacitance stability. Both parts maintain identical mechanical compatibility and thermal performance across the specified operating range. Selection between these parts should be based on application voltage requirements and tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can 1825AC473KAT1A replace 1825CC473MAT3A\SB in my circuit?

A: Yes. The substitute part maintains identical capacitance (0.047 µF), package (1825), mounting type (Surface Mount MLCC), and temperature coefficient (X7R). The higher voltage rating (1000V vs. 630V) and tighter tolerance (±10% vs. ±20%) make it electrically and mechanically compatible.

Q: What is the difference in voltage rating between these parts?

A: The main part is rated at 630V, while the substitute is rated at 1000V (1kV). The higher rating in the substitute part provides additional voltage margin and is suitable for applications with higher voltage stress requirements.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 1825 (4564 Metric) package with identical dimensions: 4.50mm length × 6.40mm width × 2.54mm maximum thickness. They are mechanically interchangeable on PCBs designed for this package.

Q: Does the tolerance difference affect compatibility?

A: The substitute part has ±10% tolerance compared to ±20% for the main part. Tighter tolerance is generally beneficial for applications requiring more precise capacitance values. Both tolerances are within acceptable ranges for general-purpose applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both 1825CC473MAT3A\SB and 1825AC473KAT1A are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What packaging options are available?

A: The main part is available in standard packaging, while the substitute part is supplied in Tape & Reel (TR) format. Verify packaging requirements for your procurement and assembly processes.
