KYOCERA AVX 1825WC472MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825WC472MAT1A is a high-voltage ceramic capacitor rated at 4700 pF with 2500V (2.5kV) operating voltage and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 1825 (4564 Metric) package is designed for general-purpose high-voltage applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant with MSL 1 rating, indicating unlimited moisture sensitivity protection. Substitute parts are identified to provide alternative sourcing options with equivalent or enhanced electrical characteristics while maintaining mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825WC472MAT1A is determined by the following critical parameters:

• Capacitance Value: Must be 4700 pF (exact match required)
• Package / Case: Must be 1825 (4564 Metric) for mechanical 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 2500V (2.5kV)
• Tolerance: May vary (±10% or ±20% acceptable based on circuit requirements)
• Compliance: Must maintain ROHS3 and MSL 1 status

Three substitute parts meet these criteria with enhanced or equivalent specifications:

1. 1825HC472KAT1A - Upgraded voltage rating (3kV) with tighter tolerance (±10%)
2. 1825HC472MAT1A - Upgraded voltage rating (3kV) with matching tolerance (±20%)
3. 1825WC472KAT1A - Same voltage rating (2.5kV) with tighter tolerance (±10%)

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full ROHS3 compliance with MSL 1 rating, ensuring regulatory and environmental compatibility with the original 1825WC472MAT1A.

1825HC472KAT1A provides the highest performance margin with 3kV voltage rating and ±10% tolerance. This part is suitable for applications requiring enhanced voltage headroom and tighter capacitance tolerance specifications.

1825HC472MAT1A offers 3kV voltage rating while maintaining ±20% tolerance matching the original part. This substitution provides increased voltage margin without tolerance specification changes.

1825WC472KAT1A maintains the 2.5kV voltage rating of the original part while providing ±10% tolerance improvement. This substitution is appropriate for applications where voltage rating equivalence is required with enhanced capacitance accuracy.

All parts are manufactured by KYOCERA AVX with identical mechanical dimensions, thermal characteristics, and compliance certifications, ensuring direct circuit board compatibility.

Frequently Asked Questions (FAQ)

Q: Can 1825HC472KAT1A replace 1825WC472MAT1A in my circuit?

A: Yes. The 1825HC472KAT1A is mechanically and electrically compatible. It provides identical capacitance (4700 pF), same package (1825), same temperature coefficient (X7R), and same operating temperature range (-55°C to 125°C). The 3kV voltage rating exceeds the 2.5kV requirement, and ±10% tolerance is tighter than the original ±20%.

Q: What is the difference between 1825HC472MAT1A and 1825HC472KAT1A?

A: Both parts have 3kV voltage rating and 1825 package. The primary difference is tolerance: 1825HC472MAT1A has ±20% tolerance (matching the original part), while 1825HC472KAT1A has ±10% tolerance (tighter specification).

Q: Is 1825WC472KAT1A a direct substitute?

A: Yes. The 1825WC472KAT1A maintains the 2.5kV voltage rating and 1825 package of the original part. The only difference is improved ±10% tolerance versus the original ±20%.

Q: Do all substitute parts have the same physical dimensions?

A: Yes. All parts use the 1825 (4564 Metric) package with identical dimensions: 0.177" L x 0.252" W (4.50mm x 6.40mm) and 0.100" (2.54mm) maximum thickness. They are mechanically interchangeable on the PCB.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental and regulatory status.

Q: Which substitute should I choose for maximum reliability?

A: Selection depends on circuit requirements. For maximum voltage margin, choose 1825HC472KAT1A (3kV). For voltage equivalence with tolerance improvement, choose 1825WC472KAT1A (2.5kV, ±10%). For voltage upgrade with original tolerance, choose 1825HC472MAT1A (3kV, ±20%).
