Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2225CC124MAT3A\SB 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 mechanical and electrical compatibility
• Temperature Coefficient: Must be X7R to maintain stable capacitance performance across the operating temperature range
• Mounting Type: Must be Surface Mount, MLCC
• Voltage Rating: May be equal to or greater than 630V; higher voltage ratings provide design margin and are acceptable substitutes
• Tolerance: May be tighter (lower) than ±20%; tighter tolerances are acceptable
• Compliance Standards: 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.

Parameter Comparison

Engineering Selection Recommendations

The 2225AC124KAT1A is a direct substitute for the obsolete 2225CC124MAT3A\SB. The substitute part maintains identical physical dimensions, capacitance value, temperature coefficient, and compliance certifications while providing an upgraded voltage rating of 1000V versus the original 630V specification. The improved tolerance of ±10% compared to ±20% provides additional design margin for capacitance stability.

The substitute part is classified as Active product status, ensuring continued availability and manufacturing support. Both parts maintain ROHS3 compliance and MSL 1 rating, confirming suitability for standard surface mount assembly processes without additional moisture control requirements.

The higher voltage rating of the substitute part introduces no circuit compatibility issues in applications designed for 630V operation, as the substitute will operate well within its rated specifications. The tighter tolerance specification of the substitute part is a performance improvement that does not compromise compatibility.

Frequently Asked Questions (FAQ)

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

A: Yes. The substitute part is mechanically and electrically compatible. Both parts share identical capacitance (0.12 µF), package dimensions (2225 / 5763 Metric), temperature coefficient (X7R), and operating temperature range (-55°C to 125°C). The substitute provides a higher voltage rating (1000V vs. 630V) and tighter tolerance (±10% vs. ±20%), both of which are compatible with the original design.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The 1000V rating on the substitute part provides additional design margin compared to the original 630V specification. In applications designed for 630V operation, the substitute part will operate at a lower stress level, which may improve reliability and longevity. No circuit modifications are required.

Q: Are there any package or mounting differences between these parts?

A: No. Both parts use the identical 2225 (5763 Metric) surface mount package with dimensions of 5.72mm length × 6.35mm width × 2.54mm maximum thickness. No PCB layout or assembly process changes are necessary.

Q: Do both parts meet the same compliance and environmental standards?

A: Yes. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Both parts are suitable for standard surface mount assembly without special moisture control procedures.

Q: Why is the original part classified as obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand and production decisions. The availability of the active substitute part 2225AC124KAT1A ensures continued design support and component procurement for applications requiring this capacitance and voltage specification.
