Substitute Part Grouping Explanation

Substitution of the 2225CC124MAT3A is determined by the following critical parameters:

• Capacitance Value: Must be 0.12 µF (exact match required)
• Package / Case: Must be 2225 (5763 Metric) for PCB compatibility
• Temperature Coefficient: Must be X7R for stable performance across -55°C to 125°C
• Mounting Type: Must be Surface Mount, MLCC
• Voltage Rating: Must be equal to or greater than 630V
• Tolerance: May be equal to or tighter than ±20%
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part 2225AC124KAT1A meets all substitution criteria with an upgraded voltage rating of 1000V (1kV) and improved tolerance of ±10%, while maintaining identical physical dimensions, temperature coefficient, and compliance certifications.

• Physical Compatibility: Identical 2225 package dimensions ensure direct PCB footprint compatibility without layout modifications
• Active Product Status: The substitute is an active product from the same manufacturer, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 rating, meeting environmental and reliability requirements

Frequently Asked Questions (FAQ)

Q: Can the 2225AC124KAT1A be used as a direct replacement for the 2225CC124MAT3A?

A: Yes. Both parts share identical capacitance (0.12 µF), temperature coefficient (X7R), operating temperature range (-55°C to 125°C), and 2225 package dimensions. The substitute features a higher voltage rating (1000V vs. 630V) and tighter tolerance (±10% vs. ±20%), making it functionally compatible and electrically superior for the same application space.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use the identical 2225 (5763 Metric) surface mount package with matching physical dimensions (5.72mm × 6.35mm × 2.54mm max thickness). No PCB footprint or layout modifications are required.

Q: Does the higher voltage rating of the substitute affect circuit performance?

A: No. The higher 1000V rating of the substitute does not degrade performance in circuits designed for 630V operation. The capacitance value, temperature coefficient, and operating temperature range remain identical, ensuring equivalent electrical behavior.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 2225CC124MAT3A and 2225AC124KAT1A are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) ratings, meeting current environmental and reliability standards.

Q: Why is the original part marked as obsolete?

A: The 2225CC124MAT3A is classified as obsolete by the manufacturer. The 2225AC124KAT1A represents the active equivalent in the product line, offering improved specifications while maintaining full functional compatibility.
