1825AC472MAT3A\SB Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 1825AC472MAT3A\SB is a 4700 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX with X7R temperature coefficient and 1000V rated voltage. This surface-mount MLCC (multilayer ceramic capacitor) in 1825 package (4564 metric) is designed for general-purpose applications requiring stable capacitance across operating temperatures from -55°C to 125°C. The part is active, ROHS3 compliant, and carries unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified based on matching capacitance value, package size, and voltage rating compatibility while allowing for controlled variations in tolerance and temperature coefficient characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by three core parameters: capacitance value, package size, and voltage rating. All substitute parts maintain the 4700 pF capacitance and 1825 package footprint. Voltage rating substitution follows this logic:

• Parts rated at 1000V or higher are electrically compatible with the 1825AC472MAT3A\SB
• Tolerance variations (±5%, ±10%, ±20%) are acceptable based on circuit requirements
• Temperature coefficient changes (X7R to C0G/NP0) represent different dielectric materials with distinct stability characteristics
• All substitutes maintain identical physical dimensions (0.177" L × 0.252" W, 4.50mm × 6.40mm) and are ROHS3 compliant with MSL 1 rating

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are active products with ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the 1825AC472MAT3A\SB. Selection between substitutes depends on application-specific requirements:

1825AA472JAT1A provides tighter capacitance tolerance (±5%) with C0G/NP0 temperature coefficient, offering superior stability for precision circuits. Thickness increases to 0.110" (2.80mm), requiring PCB layout verification. Voltage rating remains at 1000V.

1825HC472KAT1A and 1825HC472MAT1A offer elevated voltage ratings (3000V) while maintaining X7R temperature coefficient and 0.100" thickness. The ±10% tolerance variant (KAT1A) provides better capacitance accuracy than the ±20% variant (MAT1A). Both are suitable for high-voltage applications where the original 1000V rating is insufficient.

1825WC472KAT1A provides intermediate voltage rating (2500V) with ±10% tolerance and X7R coefficient, positioned between the original part and the 3000V options. Thickness matches the original specification at 0.100".

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with higher voltage rating than the original 1825AC472MAT3A\SB?

A: Yes. A capacitor rated for 3000V or 2500V will function correctly in a circuit designed for 1000V operation. Higher voltage ratings provide additional safety margin and do not degrade performance in lower-voltage applications.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R dielectric exhibits ±15% capacitance change across the -55°C to 125°C operating range. C0G/NP0 dielectric provides superior stability with minimal capacitance drift over temperature. Selection depends on circuit tolerance requirements.

Q: Does the thickness difference between 0.100" and 0.110" affect PCB compatibility?

A: The 1825AA472JAT1A with 0.110" thickness requires verification of available PCB clearance above the component. Standard 1825 package footprints typically accommodate this variation, but board layout must be confirmed.

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

A: No. The original part uses unspecified packaging, while substitutes are available in Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®, or unspecified formats. Packaging selection affects procurement and assembly processes.

Q: Which substitute offers the best capacitance accuracy?

A: The 1825AA472JAT1A with ±5% tolerance provides the tightest capacitance specification. Parts with ±10% or ±20% tolerance are suitable for general-purpose applications with broader tolerance windows.
