Equivalent & Substitute Parts for 2225SC103KAT3A

Part Overview

The 2225SC103KAT3A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 10000 pF, rated voltage of 1500V (1.5kV), and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across a wide operating temperature range of -55°C to 125°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent capacitance and tolerance values are maintained while other electrical parameters may differ to meet specific application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2225SC103KAT3A are qualified based on the following criteria:

Maintained Parameters (Must Match):

• Capacitance: 10000 pF
• Tolerance: ±10%
• Temperature Coefficient: X7R
• Operating Temperature Range: -55°C ~ 125°C
• Mounting Type: Surface Mount, MLCC
• Package / Case: 2225 (5763 Metric)
• Physical Dimensions: 0.225" L x 0.250" W (5.72mm x 6.35mm)
• Thickness: 0.100" (2.54mm)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Variable Parameter (Allows Substitution):

• Voltage - Rated: May be higher than the original 1500V specification

The identified substitute parts maintain identical capacitance, tolerance, temperature characteristics, and physical form factor while offering higher voltage ratings. These parts are direct functional equivalents suitable for applications where the original voltage specification is met or exceeded.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2225SC103KAT3A, 2225GC103KAT1A, and 2225HC103KAT1A—are active products manufactured by KYOCERA AVX and maintain ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on the voltage requirement of the application:

• 2225SC103KAT3A: Use when the application requires exactly 1500V (1.5kV) rated voltage.
• 2225GC103KAT1A: Use when the application requires 2000V (2kV) rated voltage or when a higher voltage margin is needed within the 2kV specification.
• 2225HC103KAT1A: Use when the application requires 3000V (3kV) rated voltage or when maximum voltage headroom is required.

All parts share identical capacitance, tolerance, temperature coefficient, physical dimensions, and compliance certifications, ensuring direct interchangeability at the circuit board level when voltage requirements are satisfied.

Frequently Asked Questions (FAQ)

Q: Can 2225GC103KAT1A or 2225HC103KAT1A be used as direct replacements for 2225SC103KAT3A?

A: Yes, both substitute parts maintain identical capacitance (10000 pF), tolerance (±10%), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), and physical form factor (2225 package, 5.72mm x 6.35mm x 2.54mm). The higher voltage ratings (2kV and 3kV respectively) are compatible with applications designed for 1500V operation.

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

A: The rated voltage specification is the only electrical parameter that differs. The 2225SC103KAT3A is rated at 1500V, the 2225GC103KAT1A at 2000V, and the 2225HC103KAT1A at 3000V. All other electrical and mechanical parameters are identical.

Q: Are there any packaging differences between these parts?

A: The main part (2225SC103KAT3A) is supplied in standard packaging, while both substitute parts (2225GC103KAT1A and 2225HC103KAT1A) are supplied in Tape & Reel (TR) format. The physical component dimensions and form factor remain identical across all three parts.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.24.0020. Moisture Sensitivity Level is 1 (Unlimited) for all parts.

Q: Which substitute part should be selected for maximum reliability in high-voltage applications?

A: Selection should be based on the actual voltage requirement of the application circuit. Using a part rated higher than necessary does not improve reliability; it only increases cost. Select the part whose voltage rating matches or exceeds the application requirement.
