KYOCERA AVX 2225CC104MAT3A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 2225CC104MAT3A is a 0.1 µF ceramic capacitor rated for 630V with X7R temperature coefficient, designed for general-purpose high-voltage applications. This surface-mount multilayer ceramic capacitor (MLCC) in 2225 package format is actively manufactured and widely stocked. Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required due to inventory constraints, application-specific tolerance requirements, or voltage margin specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2225CC104MAT3A is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 0.1 µF (exact match required)
• Temperature coefficient: X7R (ensures stable performance across operating range)
• Package / Case: 2225 (5763 Metric) (ensures mechanical and electrical compatibility on PCB)
• Mounting type: Surface Mount, MLCC (maintains assembly compatibility)
• Operating temperature range: -55°C to 125°C (minimum requirement)

Allowable Variation Parameters:

• Voltage rating: May be equal or higher than 630V (provides design margin without functional impact)
• Tolerance: May be tighter (±10% or better) than ±20% (improves circuit performance)

The identified substitute part 2225AC104KAT1A meets all mandatory matching criteria while providing enhanced voltage rating (1000V) and improved tolerance (±10%), making it suitable for applications requiring higher voltage margin or tighter capacitance specification.

Parameter Comparison

Engineering Selection Recommendations

Both the 2225CC104MAT3A and 2225AC104KAT1A are active products from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status, ensuring regulatory compliance for current and future applications.

The 2225AC104KAT1A substitute provides two engineering advantages: a 370V higher voltage rating (1000V vs. 630V) and half the tolerance specification (±10% vs. ±20%). These characteristics make the substitute suitable for applications where voltage margin is critical or where tighter capacitance tolerance improves circuit performance. The identical package, mounting type, and thermal characteristics ensure direct PCB compatibility without design modification.

Selection between the main part and substitute should be based on circuit voltage requirements and tolerance specifications. Both parts maintain identical physical footprint and thermal performance across the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Can 2225AC104KAT1A replace 2225CC104MAT3A in any application?

A: Yes, from an electrical and mechanical standpoint. The substitute has identical capacitance, temperature coefficient, package, and mounting type. The higher voltage rating (1000V vs. 630V) and tighter tolerance (±10% vs. ±20%) are compatible with any circuit designed for the original part. Verify that your circuit design does not depend on the specific ±20% tolerance specification.

Q: What is the physical difference between these parts?

A: There is no physical difference. Both parts use the 2225 (5763 Metric) package with identical dimensions: 5.72mm length, 6.35mm width, and 2.54mm maximum thickness. They mount identically on PCBs and occupy the same footprint.

Q: Why would I choose the substitute over the original part?

A: The 2225AC104KAT1A substitute offers higher voltage rating (1000V) for applications requiring greater voltage margin and tighter tolerance (±10%) for circuits sensitive to capacitance variation. Both parts are actively manufactured; selection depends on application requirements and inventory availability.

Q: Are both parts RoHS compliant?

A: Yes. Both 2225CC104MAT3A and 2225AC104KAT1A are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, suitable for standard PCB assembly and storage conditions.

Q: Can I use the original part if the substitute is specified?

A: The 2225CC104MAT3A can be used in place of 2225AC104KAT1A if the circuit can tolerate the lower voltage rating (630V vs. 1000V) and wider tolerance (±20% vs. ±10%). Verify that your application voltage does not exceed 630V and that circuit performance is acceptable with ±20% capacitance variation.
