2225SC153KAT3A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 2225SC153KAT3A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 0.015 µF capacitance with 1500V (1.5kV) voltage rating and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 2225 package is designed for general-purpose applications requiring stable performance across the -55°C to 125°C operating temperature range. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications are required for design flexibility, inventory optimization, or application-specific voltage margin requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2225SC153KAT3A is determined by the following critical parameters:

• Capacitance Value: Must be 0.015 µF
• Capacitance Tolerance: Must be ±10%
• Temperature Coefficient: Must be X7R
• Package / Case: Must be 2225 (5763 Metric)
• Physical Dimensions: Must match 0.225" L x 0.250" W (5.72mm x 6.35mm) and 0.100" (2.54mm) maximum thickness
• Mounting Type: Must be Surface Mount, MLCC
• Operating Temperature Range: Must support -55°C ~ 125°C
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The voltage rating may exceed the original specification (1500V minimum) without affecting substitution validity, as higher voltage ratings provide additional design margin while maintaining all other electrical and mechanical compatibility requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 2225SC153KAT3A and 2225HC153KAT1A are active production parts with identical ROHS3 compliance and MSL 1 ratings. The 2225HC153KAT1A provides a 3000V voltage rating compared to the 1500V rating of the main part, while maintaining all other electrical and mechanical specifications. Selection between these parts should be based on circuit voltage requirements and design margin considerations. Both parts are suitable for general-purpose applications within the specified operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the 2225HC153KAT1A replace the 2225SC153KAT3A in all applications?

A: Yes, provided the circuit design accommodates the higher 3000V voltage rating. The substitute part maintains identical capacitance (0.015 µF), tolerance (±10%), temperature coefficient (X7R), package dimensions (2225), and operating temperature range (-55°C ~ 125°C).

Q: Are there physical compatibility concerns when substituting these parts?

A: No. Both parts use the identical 2225 (5763 Metric) package with matching dimensions of 0.225" L x 0.250" W (5.72mm x 6.35mm) and 0.100" (2.54mm) maximum thickness. PCB footprints and assembly processes remain unchanged.

Q: Do compliance certifications differ between the main part and substitute?

A: No. Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the primary difference between these two parts?

A: The rated voltage differs: 2225SC153KAT3A is rated at 1500V (1.5kV), while 2225HC153KAT1A is rated at 3000V (3kV). All other specifications remain identical.

Q: Are both parts currently available?

A: Yes. Both parts are active production items. The 2225SC153KAT3A has 866 pieces in stock, and the 2225HC153KAT1A has 5200 pieces available.
