KYOCERA AVX 1825AC472MATME Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 1825AC472MATME is a 4700 pF high-voltage ceramic capacitor rated at 1000V with X7R temperature coefficient, housed in a 1825 (4564 Metric) surface mount package. This part is Active status and widely used in general-purpose high-voltage applications. Substitute parts are identified to provide alternatives with enhanced voltage ratings, improved tolerance specifications, or different temperature coefficient characteristics while maintaining the same capacitance value and package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Fixed Parameters (Must Match):

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

Variable Parameters (Allowed to Differ):

• Voltage - Rated: 1000V, 2500V, or 3000V
• Temperature Coefficient: X7R or C0G/NP0
• Tolerance: ±5%, ±10%, or ±20%
• Thickness: 2.54mm or 2.80mm

The substitute parts listed below maintain identical capacitance and package dimensions while offering enhanced voltage ratings or improved tolerance specifications suitable for applications requiring higher voltage margins or tighter capacitance tolerances.

Parameter Comparison

Engineering Selection Recommendations

For Same Voltage Rating (1000V) with Improved Tolerance: The 1825AA472JAT1A provides ±5% tolerance compared to the original ±20%, with identical 1000V rating. This part uses C0G/NP0 temperature coefficient, offering superior temperature stability. The increased thickness (2.80mm vs. 2.54mm) must be verified for PCB clearance compatibility. This part is Active status and ROHS3 compliant.

For Enhanced Voltage Margin (3000V): The 1825HC472KAT1A and 1825HC472MAT1A both provide 3000V rating with X7R temperature coefficient matching the original part's thermal characteristics. The 1825HC472KAT1A offers ±10% tolerance, while 1825HC472MAT1A maintains ±20% tolerance. Both are Active status and ROHS3 compliant. The 1825HC472KAT1A has higher inventory availability (2400 Pcs).

For Intermediate Voltage Rating (2500V): The 1825WC472KAT1A provides 2500V rating with ±10% tolerance and X7R temperature coefficient. This part is Active status and ROHS3 compliant, offering a middle-ground option between the original 1000V and the 3000V alternatives.

All substitute parts maintain identical capacitance (4700 pF), package dimensions (1825/4564 Metric), operating temperature range (-55°C ~ 125°C), and compliance certifications (ROHS3, REACH Unaffected, MSL 1).

Frequently Asked Questions (FAQ)

Q: Can I use a higher voltage-rated capacitor as a substitute? A: Yes. All substitute parts maintain the same 4700 pF capacitance and 1825 package footprint. Higher voltage ratings (2500V or 3000V) are electrically compatible with circuits designed for 1000V operation, as the capacitor will operate well within its voltage margin.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients? A: X7R provides ±15% capacitance change across the -55°C to 125°C operating range. C0G/NP0 provides superior stability with ±0.3% change across the same range. Select C0G/NP0 (1825AA472JAT1A) for applications requiring tight capacitance tolerance over temperature variations.

Q: Does the increased thickness of 1825AA472JAT1A affect PCB assembly? A: The 1825AA472JAT1A has a maximum thickness of 0.110" (2.80mm) compared to 0.100" (2.54mm) for other parts. Verify PCB clearance and component placement constraints before substitution.

Q: Are all substitute parts in active production? A: Yes. All listed substitute parts have Active product status and are available in stock from KYOCERA AVX.

Q: What packaging options are available? A: The original part has unspecified packaging. Substitute parts are available in Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, or unspecified packaging. Confirm packaging requirements for your procurement and assembly process.

Q: Are all parts RoHS3 compliant? A: Yes. All parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
