Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2225CC124MAT1A\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 for PCB assembly compatibility
• Voltage Rating: Must be equal to or greater than 630V; higher voltage ratings are acceptable as they provide design margin
• Compliance Standards: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part 2225AC124KAT1A meets all substitution criteria while offering improved specifications in voltage rating (1000V vs. 630V) and tolerance (±10% vs. ±20%), making it a direct upgrade option.

Parameter Comparison

Engineering Selection Recommendations

The 2225AC124KAT1A is a direct substitute for the obsolete 2225CC124MAT1A\SB. Both parts are manufactured by KYOCERA AVX and share identical mechanical packaging, capacitance value, and temperature coefficient specifications. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

The 2225AC124KAT1A provides enhanced electrical performance through a higher voltage rating (1000V vs. 630V) and tighter tolerance (±10% vs. ±20%), both of which are backward-compatible improvements. The increased voltage rating provides additional design margin without affecting circuit functionality in applications originally specified for 630V operation. The improved tolerance reduces capacitance variation across the product population, supporting tighter circuit performance requirements.

Both parts maintain identical RoHS3 compliance and MSL 1 ratings, confirming regulatory and environmental compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 2225AC124KAT1A be used as a direct replacement for the 2225CC124MAT1A\SB?

A: Yes. Both parts share identical capacitance (0.12 µF), package (2225), temperature coefficient (X7R), and physical dimensions. The substitute part is fully compatible for PCB assembly and electrical circuit operation.

Q: What are the key differences between these two parts?

A: The primary differences are product status, voltage rating, and tolerance. The 2225AC124KAT1A is active production (vs. obsolete), rated at 1000V (vs. 630V), and has ±10% tolerance (vs. ±20%). These represent improvements that do not affect backward compatibility.

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

A: No. A higher voltage rating is a conservative design parameter. If the original circuit was designed for 630V operation, a 1000V-rated component will function identically while providing additional safety margin.

Q: Are there any package or mounting differences?

A: No. Both parts use the 2225 (5763 Metric) surface mount package with identical physical dimensions (5.72mm × 6.35mm × 2.54mm max thickness), ensuring compatibility with existing PCB layouts and assembly processes.

Q: What is the significance of the ±10% vs. ±20% tolerance difference?

A: The tighter ±10% tolerance of the substitute part reduces capacitance variation across the product population. This may improve circuit performance in applications sensitive to capacitance tolerance, though both tolerances are acceptable for general-purpose applications.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 2225CC124MAT1A\SB and 2225AC124KAT1A are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, confirming regulatory compliance and environmental suitability.
