KYOCERA AVX 2225AC333MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 2225AC333MAT1A is a 0.033 µF high-voltage ceramic capacitor rated for 1000V (1kV) operation with X7R temperature coefficient characteristics. This surface-mount multilayer ceramic capacitor (MLCC) in 2225 package format is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1), making it suitable for standard manufacturing environments. Substitute parts are identified when equivalent capacitance and package specifications are maintained while offering enhanced electrical performance or improved availability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2225AC333MAT1A are identified based on the following critical parameters that must remain constant or improve:

• Capacitance Value: Must be 0.033 µF (no deviation)
• Package Format: Must be 2225 (5763 Metric) to ensure mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount MLCC
• Temperature Coefficient: Must be X7R for consistent performance across operating range
• Operating Temperature Range: Must support -55°C to 125°C minimum
• Compliance Standards: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part 2225GC333KAT1A qualifies as an upgrade substitute because it maintains all critical parameters while offering improved voltage rating (2000V vs. 1000V) and tighter tolerance (±10% vs. ±20%), providing enhanced performance margin in high-voltage applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 2225AC333MAT1A and 2225GC333KAT1A are active products from KYOCERA AVX with full ROHS3 compliance and unlimited moisture sensitivity rating. The 2225GC333KAT1A represents an upgrade path when circuit design permits, offering doubled voltage rating and improved capacitance tolerance. Selection between these parts should be based on circuit voltage requirements: use 2225AC333MAT1A for applications with 1000V maximum operating voltage, and 2225GC333KAT1A for circuits requiring 2000V rating or where tighter tolerance specifications are necessary. Both parts maintain identical physical footprint and thermal characteristics, ensuring direct substitution at the PCB assembly level.

Frequently Asked Questions (FAQ)

Q: Can 2225GC333KAT1A be used as a direct replacement for 2225AC333MAT1A?

A: Yes. Both parts share identical capacitance (0.033 µF), package format (2225), mounting type (Surface Mount MLCC), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). The substitute part offers higher voltage rating (2000V vs. 1000V) and tighter tolerance (±10% vs. ±20%), making it suitable for any application originally designed for the main part.

Q: What are the physical compatibility considerations?

A: Both parts use the 2225 (5763 Metric) package with identical dimensions: 5.72mm length × 6.35mm width × 2.54mm maximum thickness. PCB footprints, reflow profiles, and assembly processes remain unchanged between these parts.

Q: How do tolerance differences affect circuit performance?

A: The 2225AC333MAT1A carries ±20% tolerance, while 2225GC333KAT1A carries ±10% tolerance. For the 0.033 µF value, this represents a capacitance range of 0.0264–0.0396 µF versus 0.0297–0.0363 µF respectively. Tighter tolerance in the substitute part reduces capacitance variation across production batches.

Q: Are there compliance or certification differences?

A: Both parts are ROHS3 compliant, carry MSL 1 (unlimited moisture sensitivity), and are REACH unaffected. No compliance or certification differences exist between the two parts.

Q: When should the main part be selected over the substitute?

A: Select 2225AC333MAT1A when circuit design specifically requires 1000V maximum voltage rating and cost optimization is prioritized. The substitute 2225GC333KAT1A should be selected when higher voltage margin or tighter tolerance specifications are required by circuit design.
