KYOCERA AVX 1825GC472MATME Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825GC472MATME is a 4700 pF high-voltage ceramic capacitor rated at 2000V (2kV) with X7R temperature coefficient, housed in a 1825 (4564 Metric) surface-mount package. This 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 ROHS3 compliant, REACH unaffected, and carries an MSL rating of 1 (unlimited moisture sensitivity). Substitute parts are identified to provide design flexibility when the primary part is unavailable or when design requirements necessitate upgraded electrical specifications such as higher voltage ratings or improved tolerance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825GC472MATME is determined by the following mandatory parameters:

• Capacitance Value: Must be 4700 pF (exact match required)
• Package / Case: Must be 1825 (4564 Metric) for mechanical and electrical 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 2000V (2kV)
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

Substitute parts are grouped into two categories:

Upgrade Substitutes (KYOCERA AVX): Parts 1825HC472KAT1A, 1825HC472MAT1A, and 1825WC472KAT1A provide higher voltage ratings (3000V or 2500V) while maintaining identical physical dimensions and package specifications. These upgrades offer enhanced design margin for high-voltage applications.

Manufacturer-Recommended Substitute (KEMET): Part C1825C472MGRAC7800 provides electrical equivalence at the same 2000V rating with identical capacitance and tolerance, offering cross-manufacturer compatibility with ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and full ROHS3 compliance with MSL 1 rating, ensuring regulatory and environmental compatibility with the original 1825GC472MATME specification.

For Direct Replacement: The KEMET C1825C472MGRAC7800 provides electrical and mechanical equivalence at identical 2000V rating with ±20% tolerance. This part is suitable for direct substitution in existing designs without circuit modification.

For Upgraded Voltage Margin: The KYOCERA AVX 1825HC472KAT1A and 1825HC472MAT1A offer 3000V rating with identical physical footprint, providing 50% additional voltage headroom. The 1825HC472KAT1A additionally provides ±10% tolerance for improved capacitance stability. The 1825WC472KAT1A provides intermediate 2500V rating with ±10% tolerance.

All substitute parts share identical package dimensions (1825 / 4564 Metric), operating temperature range (-55°C to 125°C), and X7R temperature coefficient, ensuring drop-in compatibility at the board level.

Frequently Asked Questions (FAQ)

Q: Can the 1825HC472KAT1A replace the 1825GC472MATME in my circuit?

A: Yes. The 1825HC472KAT1A is a direct substitute with identical capacitance (4700 pF), package (1825), and temperature coefficient (X7R). The higher voltage rating (3000V vs. 2000V) and improved tolerance (±10% vs. ±20%) provide enhanced performance margin without circuit modification.

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

A: Both parts share identical electrical specifications (4700 pF, 3000V, X7R, -55°C to 125°C) and physical dimensions. The primary difference is packaging: 1825HC472KAT1A is supplied in Cut Tape (CT) & Digi-Reel format, while 1825HC472MAT1A is supplied in Tape & Reel (TR) format. Tolerance is ±10% for 1825HC472KAT1A and ±20% for 1825HC472MAT1A.

Q: Is the KEMET C1825C472MGRAC7800 mechanically compatible with the KYOCERA AVX 1825GC472MATME?

A: Yes. Both parts use the 1825 (4564 Metric) package with identical external dimensions (0.177" L × 0.252" W / 4.50mm × 6.40mm). The KEMET part has a reduced maximum thickness (0.061" vs. 0.100"), which is compatible with standard PCB assembly processes.

Q: Can I use the 1825WC472KAT1A as a substitute?

A: Yes. The 1825WC472KAT1A provides 2500V rating with ±10% tolerance in the same 1825 package. This part offers intermediate voltage rating and improved tolerance compared to the original 1825GC472MATME.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (1825HC472KAT1A, 1825HC472MAT1A, 1825WC472KAT1A, and C1825C472MGRAC7800) are ROHS3 compliant with MSL 1 rating, maintaining full regulatory equivalence with the original part.

Q: What does the X7R temperature coefficient mean for substitution?

A: X7R indicates capacitance variation of ±15% across the -55°C to 125°C operating range. All substitute parts maintain X7R specification, ensuring identical thermal stability characteristics and direct substitution compatibility.

Q: Can I substitute based on voltage rating alone?

A: No. Substitution requires matching capacitance value (4700 pF), package (1825), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). Voltage rating must be equal to or greater than 2000V. All other parameters must align exactly.
