1825AC333MAT3A Equivalent & Substitute Parts

Part Overview

The 1825AC333MAT3A is a 0.033 µF ceramic capacitor rated for 1000V (1kV) with X7R temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active and in stock, with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified when electrical specifications and mechanical compatibility align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825AC333MAT3A is determined by the following critical parameters:

• Capacitance Value: Must be 0.033 µF (no deviation permitted)
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R for consistent performance across the operating temperature range
• Package / Case: Must be 1825 (4564 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match or be compatible with 4.50mm L × 6.40mm W footprint
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The 1825AC333KAT1A meets all substitution criteria. The primary difference is the tolerance specification (±10% versus ±20%), which represents an upgrade in capacitance accuracy while maintaining all other electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The 1825AC333KAT1A is a direct substitute for the 1825AC333MAT3A based on electrical and mechanical equivalence. Both parts are manufactured by KYOCERA AVX, maintain active product status, and comply with ROHS3 requirements with MSL 1 rating.

The 1825AC333KAT1A offers improved capacitance tolerance (±10% versus ±20%), which may provide enhanced circuit performance in applications requiring tighter capacitance accuracy. The substitute part is supplied in Tape & Reel (TR) packaging, whereas the original is supplied in bulk format. This packaging difference does not affect electrical performance and is a consideration for assembly and procurement workflows only.

Both parts are suitable for high-voltage general-purpose applications and maintain identical thermal stability across the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can the 1825AC333KAT1A replace the 1825AC333MAT3A in existing designs?

A: Yes. Both parts have identical capacitance (0.033 µF), voltage rating (1000V), temperature coefficient (X7R), package (1825), and physical dimensions. The substitute part is electrically and mechanically compatible.

Q: What is the difference between these two parts?

A: The primary difference is capacitance tolerance. The 1825AC333MAT3A has ±20% tolerance, while the 1825AC333KAT1A has ±10% tolerance. The 1825AC333KAT1A also uses Tape & Reel packaging instead of bulk packaging.

Q: Does the tighter tolerance of the 1825AC333KAT1A affect circuit compatibility?

A: No. Tighter tolerance represents improved accuracy and is compatible with designs specified for ±20% tolerance. The substitute part will perform within the original design specifications.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel and bulk packaging formats do not affect electrical characteristics. The packaging difference is relevant only for procurement, storage, and assembly processes.

Q: Can the 1825AC333MAT3A be used in place of the 1825AC333KAT1A?

A: Yes, from an electrical and mechanical standpoint. However, the original part has wider tolerance (±20%), which may not meet design requirements if tighter tolerance is specified.
