Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2225AC104MAT1A is determined by the following critical parameters:

• Capacitance Value: Must be 0.1 µF (no deviation permitted)
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R (ensures stable capacitance across operating temperature range)
• Package / Case: Must be 2225 (5563 Metric) for mechanical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match or be compatible with 5.72mm L × 6.35mm W footprint
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The 2225AC104KAT1A qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary difference is the tolerance specification (±10% versus ±20%), which represents an upgrade in capacitance accuracy while maintaining all other functional requirements.

Parameter Comparison

Engineering Selection Recommendations

The 2225AC104KAT1A is a qualified substitute for the 2225AC104MAT1A in applications where the 0.1 µF capacitance value, 1000V voltage rating, and X7R temperature stability are required. Both parts maintain identical electrical performance specifications and physical form factors. The 2225AC104KAT1A offers improved capacitance tolerance (±10% versus ±20%), which may provide tighter circuit performance in applications sensitive to capacitance variation. Both parts are ROHS3 compliant and carry MSL 1 rating, confirming suitability for standard manufacturing and storage conditions. Selection between these parts should be based on packaging requirements (Tape & Reel versus Cut Tape / Digi-Reel) and tolerance specifications appropriate to the circuit design.

Frequently Asked Questions (FAQ)

Q: Can the 2225AC104KAT1A replace the 2225AC104MAT1A in existing designs?

A: Yes. Both parts share identical capacitance (0.1 µF), voltage rating (1000V), temperature coefficient (X7R), and physical dimensions (2225 package). The substitute part offers improved tolerance (±10% versus ±20%), making it functionally compatible for direct substitution.

Q: What is the difference between Tape & Reel and Cut Tape / Digi-Reel packaging?

A: Tape & Reel (TR) packaging supplies components on continuous tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® packaging provides smaller quantities on cut tape segments, suitable for lower-volume production or component selection. Both formats contain identical components; packaging choice depends on production volume and assembly equipment compatibility.

Q: Does the tolerance difference affect circuit performance?

A: The 2225AC104KAT1A tolerance of ±10% is tighter than the ±20% tolerance of the 2225AC104MAT1A. In applications where capacitance accuracy is critical, the ±10% tolerance part provides improved performance consistency. For general-purpose applications, both tolerances are typically acceptable.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both parts maintain the X7R temperature coefficient and operate across the -55°C to 125°C temperature range, ensuring stable capacitance performance in high-temperature environments.

Q: Do both parts meet current compliance requirements?

A: Yes. Both the 2225AC104MAT1A and 2225AC104KAT1A are ROHS3 compliant and carry MSL 1 (unlimited) moisture sensitivity rating, meeting current environmental and manufacturing standards.
