2225AC333MAT3A\SB Equivalent & Substitute Parts

Part Overview

The 2225AC333MAT3A\SB 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 in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified when design requirements allow for higher voltage ratings or improved tolerance specifications while maintaining the same capacitance value and physical package dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2225AC333MAT3A\SB is determined by the following critical parameters:

• Capacitance Value: Must remain 0.033 µF (exact match required)
• Package Dimensions: Must be 2225 (5763 Metric) for mechanical compatibility
• Temperature Coefficient: Must be X7R for thermal stability equivalence
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Mounting Type: Must be Surface Mount MLCC
• Voltage Rating: May be equal to or greater than 1000V
• Tolerance: May be equal to or tighter than ±20%
• Compliance: Must maintain ROHS3 and REACH compliance status

The identified substitute part 2225GC333KAT1A meets all mechanical and electrical compatibility criteria while offering an upgraded voltage rating of 2000V (2kV) and improved tolerance of ±10%.

Parameter Comparison

Engineering Selection Recommendations

The 2225GC333KAT1A serves as a direct substitute for the 2225AC333MAT3A\SB in applications where the design specifications permit. Both parts are manufactured by KYOCERA AVX and maintain identical mechanical compatibility and thermal performance characteristics. The substitute part provides enhanced electrical performance through a doubled voltage rating (2000V versus 1000V) and tighter capacitance tolerance (±10% versus ±20%), making it suitable for designs requiring higher voltage margins or improved precision. Both parts maintain full ROHS3 compliance and unlimited moisture sensitivity rating, ensuring equivalent environmental and regulatory compliance. Selection between these parts should be based on circuit voltage requirements and tolerance specifications rather than availability or performance limitations.

Frequently Asked Questions (FAQ)

Q: Can 2225GC333KAT1A replace 2225AC333MAT3A\SB in any application?

A: The 2225GC333KAT1A is electrically and mechanically compatible with 2225AC333MAT3A\SB. The substitute part's higher voltage rating and tighter tolerance do not create incompatibility. However, circuit design specifications should be reviewed to confirm that the substitute part meets or exceeds all required electrical parameters.

Q: What is the difference in voltage rating between these parts?

A: The main part is rated for 1000V (1kV), while the substitute is rated for 2000V (2kV). This difference allows the substitute to be used in higher-voltage applications or to provide additional voltage margin in existing designs.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 2225 (5763 Metric) package with identical dimensions of 5.72mm length × 6.35mm width × 2.54mm maximum thickness. They are mechanically interchangeable on PCBs designed for the 2225 package footprint.

Q: Do both parts have the same temperature stability?

A: Yes. Both parts feature X7R temperature coefficient and operate across the identical temperature range of -55°C to 125°C, providing equivalent thermal performance.

Q: What is the tolerance difference, and does it matter?

A: The main part has ±20% tolerance, while the substitute has ±10% tolerance. The substitute offers tighter capacitance accuracy. If the circuit design requires ±20% tolerance or looser, both parts are acceptable. If tighter tolerance is required, the substitute is preferred.

Q: Are both parts RoHS compliant?

A: Yes. Both 2225AC333MAT3A\SB and 2225GC333KAT1A are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.
