Key Parameters

Substitute Part Grouping Explanation

Substitution for the 2225CC124MAT1A is determined by the following critical parameters:

• Capacitance Value: Must be 0.12 µF
• Package / Case: Must be 2225 (5763 Metric) for mechanical and electrical compatibility
• Temperature Coefficient: Must be X7R to maintain stable capacitance across the operating temperature range
• Mounting Type: Must be Surface Mount, MLCC
• Physical Dimensions: Must match 0.225" L x 0.250" W (5.72mm x 6.35mm) and 0.100" (2.54mm) thickness
• Voltage Rating: Must meet or exceed 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 these criteria while offering an upgraded voltage rating of 1000V (1kV) and improved tolerance of ±10%, with active product status ensuring continued availability.

Parameter Comparison

Engineering Selection Recommendations

The 2225AC124KAT1A is a direct substitute for the 2225CC124MAT1A based on identical capacitance, package, temperature coefficient, and physical dimensions. The substitute part provides two engineering advantages: active product status ensuring long-term availability and supply chain continuity, and improved voltage margin with 1000V rating compared to the original 630V specification. The tighter tolerance of ±10% versus ±20% provides enhanced capacitance accuracy for precision applications. Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical capacitance (0.12 µF), temperature coefficient (X7R), package (2225), physical dimensions, and operating temperature range. The substitute part is electrically and mechanically compatible.

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

A: The 2225AC124KAT1A is rated at 1000V compared to 630V on the original part. This provides additional voltage margin and allows the substitute to be used in applications requiring higher voltage ratings without derating.

Q: Does the ±10% tolerance on the substitute part affect compatibility?

A: No. Tighter tolerance is a beneficial upgrade. The ±10% tolerance on the substitute part is more stringent than the ±20% on the original part, providing improved capacitance accuracy while remaining compatible with circuit designs specified for ±20%.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both parts use the 2225 (5763 Metric) package with dimensions of 0.225" L x 0.250" W (5.72mm x 6.35mm) and thickness of 0.100" (2.54mm), ensuring identical PCB footprint and assembly compatibility.

Q: What is the significance of the active product status for the substitute part?

A: Active product status indicates the substitute part is in current production and supported by the manufacturer. This ensures continued availability, stable pricing, and access to technical support, addressing the obsolescence of the original part.

Q: Are both parts RoHS compliant?

A: Yes. Both 2225CC124MAT1A and 2225AC124KAT1A are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, meeting standard environmental and regulatory requirements.
