KYOCERA AVX 1825GC472MAT3A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 1825GC472MAT3A is a 4700 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX with X7R temperature coefficient and 2000V rated voltage. This surface-mount multilayer ceramic capacitor (MLCC) in 1825 (4564 Metric) package is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is active, ROHS3 compliant, and carries MSL 1 rating. Substitute parts are identified when equivalent electrical performance is required due to inventory constraints, design optimization for higher voltage ratings, or tolerance improvements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825GC472MAT3A is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance: 4700 pF (exact match required)
• Temperature Coefficient: X7R (exact match required)
• Package / Case: 1825 (4564 Metric) (exact match required)
• Mounting Type: Surface Mount, MLCC (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Allowable Variation Parameters:

• Voltage - Rated: Equal to or greater than 2000V
• Tolerance: ±10% or ±20%
• Manufacturer: KYOCERA AVX or equivalent qualified manufacturer
• Packaging: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR)

Substitute parts must maintain identical electrical performance at the specified operating conditions while meeting or exceeding the voltage rating of the original part.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. Selection between substitute options depends on application voltage requirements and tolerance specifications:

1825HC472KAT1A and 1825HC472MAT1A provide upgraded voltage ratings of 3000V, suitable for applications requiring higher voltage margin or operating in elevated voltage environments. The 1825HC472KAT1A offers improved tolerance at ±10%, while 1825HC472MAT1A maintains ±20% tolerance matching the original part.

1825WC472KAT1A provides intermediate voltage rating of 2500V with ±10% tolerance, offering a balance between voltage headroom and tolerance improvement.

C1825C472MGRAC7800 from KEMET is manufacturer-recommended and maintains identical electrical specifications to the original part (2000V, ±20% tolerance) while offering reduced thickness (0.061" vs 0.100"), which may provide design flexibility for space-constrained applications. This part carries Low ESL feature designation.

Frequently Asked Questions (FAQ)

Q: Can I substitute 1825HC472KAT1A for 1825GC472MAT3A in my design?

A: Yes. The 1825HC472KAT1A is electrically compatible as a direct substitute. It maintains identical capacitance (4700 pF), temperature coefficient (X7R), package (1825), and operating temperature range (-55°C ~ 125°C). The higher voltage rating (3000V vs 2000V) and improved tolerance (±10% vs ±20%) provide enhanced performance margins.

Q: What is the difference between the KYOCERA AVX upgrade options?

A: The three KYOCERA AVX upgrades differ in voltage rating and tolerance. 1825HC472KAT1A and 1825WC472KAT1A both offer ±10% tolerance with 3000V and 2500V ratings respectively. 1825HC472MAT1A maintains ±20% tolerance with 3000V rating. All three are electrically interchangeable with the original part.

Q: Can I use C1825C472MGRAC7800 (KEMET) as a substitute?

A: Yes. The C1825C472MGRAC7800 is a manufacturer-recommended equivalent with identical electrical specifications (4700 pF, 2000V, ±20%, X7R). It is ROHS3 compliant and MSL 1 rated. The reduced thickness (0.061" vs 0.100") may provide design advantages in space-constrained layouts.

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

A: Packaging varies by part number. Verify specific packaging availability (Cut Tape, Digi-Reel®, or Tape & Reel) with your supplier before design finalization, as this affects procurement and assembly processes.

Q: What happens if I use a substitute with higher voltage rating?

A: Using a substitute with higher voltage rating (3000V or 2500V) is electrically safe and does not degrade circuit performance. Higher voltage-rated capacitors are designed to operate reliably at lower applied voltages. This provides additional safety margin in the application.

Q: Are tolerance differences significant for my application?

A: Tolerance differences (±10% vs ±20%) affect capacitance accuracy. If your circuit requires tighter capacitance tolerance, select parts with ±10% rating (1825HC472KAT1A or 1825WC472KAT1A). For general-purpose applications with ±20% tolerance acceptance, all listed substitutes are suitable.
