KYOCERA AVX 1825WC472MATME Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825WC472MATME 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 -55°C to 125°C operating range. The part is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating. Substitute parts are identified to address inventory availability, tolerance requirements, or voltage rating upgrades while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825WC472MATME is determined by the following mandatory parameters:

• Capacitance Value: Must be 4700 pF (no deviation)
• Package / Case: Must be 1825 (4564 Metric) for PCB footprint 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
• Physical Dimensions: Must match 4.50mm L × 6.40mm W footprint
• Compliance: Must maintain ROHS3 and MSL 1 ratings

Substitute parts may vary in:

• Tolerance: ±10% or ±20% (tighter tolerance represents upgrade)
• Voltage Rating: 2500V or 3000V (higher voltage rating represents upgrade)
• Packaging Format: Cut Tape (CT), Digi-Reel®, or Tape & Reel (TR)

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status with KYOCERA AVX and carry identical ROHS3 compliance and MSL 1 ratings as the primary part 1825WC472MATME. Selection among substitutes depends on application-specific requirements:

1825WC472KAT1A provides tighter capacitance tolerance (±10% versus ±20%) while maintaining the same 2500V voltage rating and identical physical footprint. This substitute is suitable for applications requiring improved capacitance accuracy without voltage rating changes.

1825HC472MAT1A and 1825HC472KAT1A both offer upgraded voltage rating to 3000V (3kV), providing additional safety margin in high-voltage circuits. The 1825HC472MAT1A maintains ±20% tolerance matching the original part, while 1825HC472KAT1A combines the 3000V upgrade with ±10% tolerance for maximum performance headroom.

All substitutes share identical package dimensions, mounting type, temperature coefficient, and operating temperature range, ensuring direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can 1825WC472KAT1A replace 1825WC472MATME in my circuit?

A: Yes. Both parts share identical capacitance (4700 pF), voltage rating (2500V), package (1825), and temperature coefficient (X7R). The 1825WC472KAT1A offers improved tolerance (±10% versus ±20%), making it a direct upgrade for applications sensitive to capacitance variation.

Q: What is the difference between the WC and HC designations in the part numbers?

A: The WC designation indicates 2500V (2.5kV) voltage rating, while HC indicates 3000V (3kV) voltage rating. Both use identical 1825 package dimensions and X7R temperature coefficient. Selection depends on circuit voltage requirements.

Q: Are the 3000V-rated parts (1825HC472MAT1A and 1825HC472KAT1A) physically compatible with the original 2500V design?

A: Yes. All four parts use the same 1825 (4564 Metric) package with identical dimensions (4.50mm L × 6.40mm W × 2.54mm max thickness). The higher voltage rating does not affect physical footprint or mounting compatibility.

Q: Does tolerance selection affect circuit performance?

A: Tolerance affects capacitance accuracy. The ±20% tolerance parts (1825WC472MATME and 1825HC472MAT1A) allow capacitance variation between 3760 pF and 5640 pF. The ±10% tolerance parts (1825WC472KAT1A and 1825HC472KAT1A) restrict variation to 4230 pF and 5170 pF. Select based on circuit sensitivity to capacitance drift.

Q: What packaging formats are available for these parts?

A: 1825WC472MATME and 1825WC472KAT1A are available in standard packaging. 1825HC472MAT1A is supplied in Tape & Reel (TR) format. 1825HC472KAT1A is available in Cut Tape (CT) and Digi-Reel® formats. Verify packaging compatibility with your procurement and assembly processes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four parts carry ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, maintaining regulatory equivalence with the original 1825WC472MATME.
