KYOCERA AVX 1825WC472MAT1A Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825WC472MAT1A is a 4700 pF ceramic capacitor rated for 2500V (2.5kV) with X7R temperature coefficient in 1825 (4564 Metric) surface mount package. This high-voltage MLCC is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant with MSL 1 rating and remains in active production status. Substitute parts are identified when equivalent electrical performance can be maintained within the same package footprint and mounting technology while meeting or exceeding the original specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825WC472MAT1A is determined by the following criteria:

Primary Compatibility Requirements:

• Capacitance value: 4700 pF (exact match required)
• Package / Case: 1825 (4564 Metric) surface mount (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)

Allowable Variations:

• Voltage Rating: Equal to or greater than 2500V
• Tolerance: ±10% or ±20% (both acceptable for general-purpose applications)
• Manufacturer: KYOCERA AVX (same manufacturer, ensuring consistency in design and reliability)

Three substitute parts meet these criteria and are grouped as direct equivalents with enhanced or equivalent electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full ROHS3 compliance with REACH unaffected designation. Selection between the main part and substitutes depends on application voltage requirements and tolerance specifications:

1825WC472KAT1A provides tighter tolerance (±10% vs ±20%) while maintaining the same 2500V voltage rating as the main part. This option is suitable for applications requiring improved capacitance accuracy without voltage margin increase.

1825HC472MAT1A and 1825HC472KAT1A both offer elevated voltage rating of 3000V, providing 500V additional margin above the original 2500V specification. The 1825HC472MAT1A maintains ±20% tolerance matching the main part, while 1825HC472KAT1A combines 3000V rating with ±10% tolerance for maximum performance headroom.

All parts are manufactured by KYOCERA AVX with identical physical dimensions, package footprint, and thermal characteristics, ensuring direct PCB compatibility and thermal management equivalence.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472MAT1A or 1825HC472KAT1A be used as direct replacements for 1825WC472MAT1A?

A: Yes. Both 3000V-rated parts are direct substitutes. They maintain identical capacitance (4700 pF), package (1825), temperature coefficient (X7R), and physical dimensions. The higher voltage rating provides additional safety margin in high-voltage applications.

Q: What is the difference between ±10% and ±20% tolerance specifications?

A: Tolerance defines the allowable deviation from the nominal 4700 pF capacitance value. ±10% tolerance (4230–5170 pF range) provides tighter capacitance accuracy compared to ±20% tolerance (3760–5640 pF range). Selection depends on circuit requirements for capacitance precision.

Q: Are all substitute parts available in the same packaging options?

A: Packaging availability varies. 1825WC472MAT1A and 1825HC472MAT1A are supplied in Tape & Reel (TR). 1825WC472KAT1A packaging is not specified. 1825HC472KAT1A is available in Cut Tape (CT) & Digi-Reel®. Verify packaging requirements with procurement specifications.

Q: Do all parts have the same moisture sensitivity level?

A: Yes. All parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or reflow processing.

Q: Can these parts be used interchangeably on existing PCBs without design changes?

A: Yes. All parts share identical 1825 (4564 Metric) package footprint and surface mount configuration, enabling direct PCB compatibility without layout modifications.
