1825AC333MATME Equivalent & Substitute Parts

Part Overview

The 1825AC333MATME 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 available in stock with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide procurement flexibility while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825AC333MATME is determined by the following critical parameters:

• Capacitance Value: Must be 0.033 µF (exact match required)
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R (ensures stable performance across -55°C to 125°C)
• Package / Case: Must be 1825 (4564 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 4.50mm L × 6.40mm W footprint
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The 1825AC333KAT1A qualifies as a direct substitute based on matching all critical parameters. The primary difference is tolerance specification (±10% versus ±20%), which represents an upgrade in capacitance accuracy without affecting substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825AC333MATME and 1825AC333KAT1A are active products from KYOCERA AVX with full ROHS3 compliance and unlimited moisture sensitivity ratings. Selection between these parts should be based on the following factors:

1825AC333MATME is suitable for applications where standard ±20% capacitance tolerance is acceptable and cost optimization is a priority.

1825AC333KAT1A is suitable for applications requiring tighter capacitance tolerance (±10%) for improved circuit performance and stability. This part is supplied in Tape & Reel packaging, which is standard for high-volume manufacturing environments.

Both parts maintain identical electrical performance across the full operating temperature range and are mechanically interchangeable in 1825 (4564 Metric) footprint designs.

Frequently Asked Questions (FAQ)

Q: Can 1825AC333KAT1A replace 1825AC333MATME in existing designs?

A: Yes. Both parts share identical capacitance value (0.033 µF), voltage rating (1000V), temperature coefficient (X7R), package footprint (1825), and physical dimensions. The 1825AC333KAT1A offers improved tolerance (±10% versus ±20%) and is a direct mechanical and electrical substitute.

Q: What is the difference between ±20% and ±10% tolerance?

A: Tolerance specifies the allowable deviation from the nominal capacitance value. The 1825AC333MATME allows ±20% deviation (0.0264 µF to 0.0396 µF), while the 1825AC333KAT1A allows ±10% deviation (0.0297 µF to 0.0363 µF). Tighter tolerance provides more predictable circuit behavior.

Q: Are there packaging differences between these parts?

A: The 1825AC333MATME is supplied in standard packaging, while the 1825AC333KAT1A is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated assembly processes and high-volume production.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8532.24.0020.

Q: Can these parts be used interchangeably in high-voltage applications?

A: Yes. Both parts are rated for 1000V (1kV) and maintain stable performance across the operating temperature range of -55°C to 125°C. The X7R temperature coefficient ensures minimal capacitance variation across this range, making them suitable for high-voltage general-purpose applications.
