Substitute Part Grouping Explanation

Substitution eligibility for the 2225CC124KAT3A\SB is determined by the following mandatory 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
• Operating Temperature Range: Must support -55°C ~ 125°C
• Voltage Rating: Must be equal to or greater than 630V

The substitute part 2225AC124KAT1A meets all mandatory substitution criteria. It maintains identical capacitance, tolerance, temperature coefficient, package dimensions, and operating temperature range. The voltage rating is upgraded to 1000V (1kV), which is compatible with applications designed for 630V operation.

Parameter Comparison

Engineering Selection Recommendations

The 2225AC124KAT1A is a direct substitute for the obsolete 2225CC124KAT3A\SB. Both parts are manufactured by KYOCERA AVX and share identical mechanical and electrical specifications except for voltage rating. The substitute part carries an active product status, ensuring long-term availability and supply chain continuity.

The voltage rating upgrade from 630V to 1000V (1kV) in the substitute part provides enhanced margin for applications operating at or near the original 630V specification. This upgrade does not introduce compatibility issues in circuits designed for 630V operation, as the substitute part maintains all other electrical and mechanical parameters.

Both parts comply with ROHS3 and REACH requirements, with identical moisture sensitivity classification (MSL 1 - Unlimited). The substitute part is suitable for direct replacement in existing designs without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)

Q: Can the 2225AC124KAT1A replace the 2225CC124KAT3A\SB in existing designs?

A: Yes. The substitute part maintains identical capacitance (0.12 µF), tolerance (±10%), temperature coefficient (X7R), package dimensions (2225), and operating temperature range (-55°C ~ 125°C). The higher voltage rating (1000V vs. 630V) is compatible with 630V-rated applications.

Q: What is the primary reason for substitution?

A: The original part 2225CC124KAT3A\SB is classified as obsolete. The 2225AC124KAT1A is an active product from the same manufacturer, ensuring continued availability and supply chain support.

Q: Are there any physical differences between these parts?

A: No. Both parts use the 2225 (5763 Metric) surface mount package with identical dimensions: 0.225" L x 0.250" W (5.72mm x 6.35mm) and maximum thickness of 0.100" (2.54mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level).

Q: Is there a cross-reference part number for the substitute?

A: The substitute part 2225AC124KAT1A has an associated cross-reference designation: CHV2225N1K0124KXT.
