1825SC472KAT3A Equivalent & Substitute Parts

Part Overview

The 1825SC472KAT3A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 4700 pF, rated at 1500V (1.5kV), and featuring X7R temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide design flexibility when the primary part is unavailable or when higher voltage ratings are required for circuit margin enhancement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825SC472KAT3A are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Capacitance: 4700 pF
• Tolerance: ±10%
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C to 125°C

Mechanical Parameters (Must Match):

• Package / Case: 1825 (4564 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 0.177" L × 0.252" W (4.50mm × 6.40mm)
• Thickness: 0.100" (2.54mm)

Allowable Variation:

• Voltage Rating: May be equal to or higher than 1500V (1.5kV)

The substitute parts listed below maintain identical capacitance, tolerance, temperature coefficient, and physical form factor while offering enhanced voltage ratings. This allows for direct substitution in applications where higher voltage margin is beneficial or required.

Parameter Comparison

Engineering Selection Recommendations

All three parts—1825SC472KAT3A, 1825HC472KAT1A, and 1825WC472KAT1A—are active products manufactured by KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. They share identical electrical characteristics (4700 pF, ±10%, X7R, -55°C to 125°C) and mechanical form factor (1825 package, 4.50mm × 6.40mm).

The primary distinction is voltage rating:

• 1825SC472KAT3A: 1500V (1.5kV)
• 1825WC472KAT1A: 2500V (2.5kV)
• 1825HC472KAT1A: 3000V (3kV)

Selection between these parts depends on circuit voltage requirements. Parts with higher voltage ratings provide increased safety margin and are suitable for direct substitution in applications originally designed for lower voltage ratings. All parts maintain unlimited moisture sensitivity (MSL 1), eliminating moisture-related handling constraints.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472KAT1A replace 1825SC472KAT3A in my circuit?

A: Yes. The 1825HC472KAT1A is a direct substitute with identical capacitance (4700 pF), tolerance (±10%), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and physical dimensions (1825 package, 4.50mm × 6.40mm). The higher voltage rating (3000V vs. 1500V) provides additional circuit margin and is compatible with applications designed for the 1825SC472KAT3A.

Q: What is the difference between 1825WC472KAT1A and 1825HC472KAT1A?

A: Both parts are equivalent substitutes for 1825SC472KAT3A with identical capacitance and form factor. The difference is voltage rating: 1825WC472KAT1A is rated at 2500V (2.5kV), while 1825HC472KAT1A is rated at 3000V (3kV). Selection depends on required voltage margin in the application.

Q: Are these parts interchangeable on the PCB?

A: Yes. All three parts use the same 1825 (4564 Metric) surface-mount package with identical physical dimensions (0.177" L × 0.252" W, 4.50mm × 6.40mm) and thickness (0.100" / 2.54mm). They are directly interchangeable at the PCB level without layout modifications.

Q: Do these parts have different moisture sensitivity requirements?

A: No. All three parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life and no special moisture handling requirements. Storage and handling procedures are identical across all three parts.

Q: Are all parts ROHS3 compliant?

A: Yes. The 1825SC472KAT3A, 1825HC472KAT1A, and 1825WC472KAT1A are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
