2225CC124KAT1A Equivalent & Substitute Parts

Part Overview

The 2225CC124KAT1A is a 0.12 µF ceramic capacitor rated at 630V with X7R temperature coefficient, manufactured by KYOCERA AVX in a 2225 (5763 Metric) surface mount package. This part is currently obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. The part's high voltage rating and general-purpose application profile support direct substitution with compatible alternatives that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2225CC124KAT1A is determined by the following critical parameters:

• Capacitance Value: Must be 0.12 µF
• Tolerance: Must be ±10%
• Temperature Coefficient: Must be X7R
• Package / Case: Must be 2225 (5763 Metric)
• 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) maximum thickness
• Voltage Rating: Must be equal to or greater than 630V

The 2225AC124KAT1A qualifies as a direct substitute because it maintains identical capacitance, tolerance, temperature coefficient, package, and physical dimensions while providing an upgraded voltage rating of 1000V (1kV). This higher voltage rating ensures compatibility in all applications where the original 630V part was specified.

Parameter Comparison

Engineering Selection Recommendations

The 2225AC124KAT1A is the recommended substitute for the obsolete 2225CC124KAT1A. Both parts are manufactured by KYOCERA AVX and share identical electrical specifications for capacitance, tolerance, and temperature coefficient. The substitute maintains full mechanical and thermal compatibility through identical package dimensions and operating temperature range.

The primary distinction is the voltage rating upgrade from 630V to 1000V (1kV). This higher rating provides enhanced design margin and is suitable for all applications originally specified for the 630V part. Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring equivalent environmental and regulatory compliance.

The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the 2225AC124KAT1A be used as a direct replacement for the 2225CC124KAT1A?

A: Yes. The substitute maintains identical capacitance (0.12 µF), tolerance (±10%), temperature coefficient (X7R), package (2225), and physical dimensions. The higher voltage rating (1kV vs. 630V) is compatible with all applications specified for the original part.

Q: Are the physical dimensions identical between the main part and substitute?

A: Yes. Both parts measure 0.225" L x 0.250" W (5.72mm x 6.35mm) with a maximum thickness of 0.100" (2.54mm), ensuring identical PCB footprint and assembly compatibility.

Q: What is the significance of the voltage rating difference?

A: The substitute's 1000V rating provides a higher voltage margin than the original 630V rating. This upgrade does not affect performance in circuits designed for 630V operation and may improve reliability in high-voltage applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2225CC124KAT1A and 2225AC124KAT1A are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory requirements.

Q: What is the moisture sensitivity level for these parts?

A: Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions and no special storage or handling requirements.
