1825AC472MAT1A Equivalent & Substitute Parts

Part Overview

The 1825AC472MAT1A is a 4700 pF ceramic capacitor rated at 1000V (1kV) with X7R temperature coefficient, manufactured by KYOCERA AVX in 1825 (4564 Metric) surface mount package. This component is active and in production, with 902 units currently in stock. Substitute parts are identified when equivalent capacitance and voltage ratings can be achieved through alternative temperature coefficients, tolerance grades, or higher voltage ratings that maintain backward compatibility in circuit applications.

Substitute Part Grouping Explanation

Substitution eligibility for the 1825AC472MAT1A is determined by the following criteria:

Primary Substitution Parameters:

• Capacitance value: 4700 pF (fixed requirement)
• Package / Case: 1825 (4564 Metric) (fixed requirement)
• Mounting Type: Surface Mount, MLCC (fixed requirement)
• Voltage Rating: Equal to or greater than 1000V (1kV)
• Temperature Coefficient: X7R or C0G/NP0 (both acceptable for general purpose applications)
• Tolerance: ±20%, ±10%, or ±5% (tighter tolerances are acceptable)
• Operating Temperature Range: -55°C ~ 125°C (minimum requirement)
• RoHS Status: ROHS3 Compliant (compliance requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling requirement)

Substitute Parts Identified:

1. 1825AA472JAT1A — Upgrade to C0G/NP0 temperature coefficient with tighter ±5% tolerance at 1000V rating
2. 1825HC472KAT1A — Upgrade to 3000V (3kV) rating with ±10% tolerance, X7R coefficient
3. 1825HC472MAT1A — Upgrade to 3000V (3kV) rating with ±20% tolerance, X7R coefficient
4. 1825WC472KAT1A — Upgrade to 2500V (2.5kV) rating with ±10% tolerance, X7R coefficient

All substitute parts maintain identical physical dimensions, package type, and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products manufactured by KYOCERA AVX with ROHS3 compliance and MSL 1 rating, ensuring equivalent handling and environmental compliance to the 1825AC472MAT1A.

1825AA472JAT1A is suitable for applications requiring tighter capacitance tolerance (±5%) at the same 1000V rating. The C0G/NP0 temperature coefficient provides superior temperature stability compared to X7R. Note the increased thickness of 0.110" (2.80mm) versus 0.100" (2.54mm) for the main part.

1825HC472KAT1A and 1825HC472MAT1A provide voltage rating upgrades to 3000V (3kV) while maintaining the same physical footprint and X7R temperature coefficient. These are suitable for applications where higher voltage margin is required. 1825HC472KAT1A offers ±10% tolerance; 1825HC472MAT1A maintains ±20% tolerance matching the original part.

1825WC472KAT1A provides an intermediate voltage upgrade to 2500V (2.5kV) with ±10% tolerance, suitable for applications requiring voltage margin between 1kV and 3kV ratings.

Frequently Asked Questions (FAQ)

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

A: Yes, for voltage and capacitance requirements. The 1825AA472JAT1A maintains the same 1000V rating and 4700 pF capacitance. The primary differences are tighter tolerance (±5% vs ±20%) and C0G/NP0 temperature coefficient (superior stability vs X7R). The increased thickness of 0.110" (2.80mm) must be verified against PCB assembly clearance specifications.

Q: What is the advantage of upgrading to 1825HC472KAT1A or 1825HC472MAT1A?

A: Both parts provide 3000V (3kV) voltage rating, offering a 3x voltage margin compared to the 1000V original part. This is beneficial for applications subject to voltage transients or requiring extended component life under stress. Physical dimensions and package type remain identical.

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

A: Packaging varies by part number. 1825AC472MAT1A is available in standard packaging; 1825AA472JAT1A is supplied in Tape & Reel (TR); 1825HC472KAT1A is supplied in Cut Tape (CT) & Digi-Reel®; 1825HC472MAT1A is supplied in Tape & Reel (TR); 1825WC472KAT1A packaging is not specified. Verify packaging compatibility with procurement and assembly requirements.

Q: Can I use a higher voltage rated part as a direct substitute?

A: Yes. Higher voltage ratings (2500V or 3000V) are backward compatible with 1000V applications. The capacitance value and physical dimensions remain constant. Higher voltage ratings may result in slightly different dielectric characteristics due to different material formulations, but all parts maintain X7R or C0G/NP0 temperature coefficients within the specified operating range.

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

A: X7R provides ±15% capacitance change over the -55°C to 125°C temperature range. C0G/NP0 provides 0±30 ppm/°C, resulting in minimal capacitance drift across temperature. C0G/NP0 is preferred for precision applications; X7R is suitable for general purpose applications with higher capacitance density.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of the 1825AC472MAT1A.
