1825AC472MAT1A Ceramic Capacitor Equivalent & Substitute Parts

Part Overview

The 1825AC472MAT1A is a 4700 pF high-voltage ceramic capacitor manufactured by KYOCERA AVX with an 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 temperature ranges from -55°C to 125°C. The part is active in production, ROHS3 compliant, and carries unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent capacitance and package dimensions are maintained while allowing variations in voltage rating, tolerance, or temperature coefficient characteristics that remain within acceptable electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1825AC472MAT1A is determined by the following allowable parameter variations:

Fixed Parameters (Must Match):

• Capacitance: 4700 pF
• Package / Case: 1825 (4564 Metric)
• Mounting Type: Surface Mount, MLCC
• Physical Dimensions: 0.177" L x 0.252" W (4.50mm x 6.40mm)
• Operating Temperature Range: -55°C to 125°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameters (Allowed to Differ):

• Voltage Rating: May be higher than 1000V (1kV) for drop-in replacement
• Tolerance: May be tighter (±5%, ±10%) than ±20%
• Temperature Coefficient: May be C0G/NP0 (superior stability) instead of X7R
• Thickness: Minor variations within mechanical constraints

Substitute parts maintain identical capacitance and package footprint while offering enhanced voltage ratings, improved tolerance specifications, or superior temperature stability characteristics.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance, ensuring long-term availability and regulatory conformance. Selection among substitutes depends on circuit requirements:

1825AA472JAT1A provides superior capacitance tolerance (±5%) with C0G/NP0 temperature coefficient, delivering enhanced frequency and temperature stability. Maintains 1000V rating with identical footprint. Thickness increases to 0.110" (2.80mm), requiring PCB clearance verification. Suitable for precision applications where capacitance drift must be minimized.

1825HC472KAT1A and 1825HC472MAT1A offer elevated voltage ratings (3000V) while maintaining X7R temperature coefficient and identical physical footprint. 1825HC472KAT1A provides ±10% tolerance; 1825HC472MAT1A maintains ±20% tolerance. Both support higher voltage stress conditions without dimensional changes. Thickness remains 0.100" (2.54mm).

1825WC472KAT1A provides intermediate voltage rating (2500V) with ±10% tolerance and X7R temperature coefficient. Maintains 0.100" (2.54mm) thickness and identical footprint. Suitable for applications requiring voltage margin above 1000V but below 3000V.

All substitutes are electrically and mechanically compatible with the original 1825AC472MAT1A footprint and mounting requirements.

Frequently Asked Questions (FAQ)

Q: Can 1825AA472JAT1A replace 1825AC472MAT1A in all applications?

A: 1825AA472JAT1A is mechanically and electrically compatible as a direct substitute. The C0G/NP0 temperature coefficient provides superior stability compared to X7R, and ±5% tolerance is tighter than ±20%. However, thickness increases from 0.100" to 0.110" (2.54mm to 2.80mm), requiring verification of available PCB clearance above the component.

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 delivers superior stability with minimal capacitance drift across temperature. Selection depends on circuit sensitivity to capacitance variation.

Q: Can higher voltage-rated parts (3000V or 2500V) be used in place of the 1000V original?

A: Yes. 1825HC472KAT1A (3000V), 1825HC472MAT1A (3000V), and 1825WC472KAT1A (2500V) are direct mechanical and electrical substitutes. Higher voltage ratings provide additional safety margin and are compatible with 1000V circuit requirements. All maintain identical 1825 package footprint and mounting characteristics.

Q: Are there packaging differences among substitute parts?

A: 1825AC472MAT1A is supplied in Tape & Reel (TR) packaging. 1825AA472JAT1A uses Tape & Reel (TR). 1825HC472KAT1A uses Cut Tape (CT) & Digi-Reel®. 1825HC472MAT1A uses Tape & Reel (TR). 1825WC472KAT1A packaging is unspecified. Verify packaging compatibility with assembly equipment and procurement requirements.

Q: Do all substitute parts maintain ROHS3 compliance and MSL 1 rating?

A: Yes. All listed substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental and regulatory specifications.
