2225CC124KAT3A Equivalent & Substitute Parts

Part Overview

The 2225CC124KAT3A 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 components meeting identical or superior electrical specifications within the same package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2225CC124KAT3A is determined by the following critical parameters:

• Capacitance Value: Must be 0.12 µF (±10% tolerance acceptable)
• Voltage Rating: Must be equal to or greater than 630V
• Temperature Coefficient: Must be X7R to maintain stable capacitance across the operating temperature range
• Package Footprint: Must be 2225 (5763 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• 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), providing enhanced margin for high-voltage applications while maintaining identical capacitance, tolerance, temperature coefficient, and package specifications.

Parameter Comparison

Engineering Selection Recommendations

The 2225AC124KAT1A is a direct substitute for the obsolete 2225CC124KAT3A. Both components are manufactured by KYOCERA AVX and share identical electrical specifications for capacitance, tolerance, and temperature coefficient. The substitute part maintains full ROHS3 compliance and MSL 1 rating, ensuring compatibility with existing manufacturing and assembly processes.

The primary distinction is the voltage rating upgrade from 630V to 1000V (1kV). This higher voltage rating provides increased design margin in high-voltage applications without altering the physical footprint, electrical performance, or compliance profile. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 2225AC124KAT1A be used as a direct replacement for the 2225CC124KAT3A?

A: Yes. Both parts share identical capacitance (0.12 µF), tolerance (±10%), temperature coefficient (X7R), package footprint (2225), and mounting type (Surface Mount, MLCC). The substitute has a higher voltage rating (1000V vs. 630V), which is compatible with applications designed for the original part.

Q: What is the physical compatibility between these two parts?

A: Both parts have identical dimensions (0.225" L x 0.250" W / 5.72mm x 6.35mm) and maximum thickness (0.100" / 2.54mm). They are mechanically interchangeable on PCBs designed for the 2225 package footprint.

Q: Are there compliance differences between the main part and substitute?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Compliance profiles are identical.

Q: Why is the substitute part rated at 1000V instead of 630V?

A: The 2225AC124KAT1A is an upgraded variant within the same product family. The higher voltage rating provides additional design margin for high-voltage applications while maintaining all other electrical and physical specifications.

Q: Is the substitute part currently available?

A: Yes. The 2225AC124KAT1A is in active production status with current inventory availability, unlike the obsolete 2225CC124KAT3A.
