KYOCERA AVX 2225AC103MATBE Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 2225AC103MATBE is a 10000 pF (10 nF) ceramic capacitor rated for 1000V (1kV) with X7R temperature coefficient, housed in a 2225 (5763 Metric) surface mount package. This high-voltage multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across the operating temperature range of -55°C to 125°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent capacitance and package dimensions are maintained while voltage ratings or tolerance specifications are upgraded.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2225AC103MATBE are qualified based on the following criteria:

• Identical Capacitance: 10000 pF maintained across all substitutes
• Identical Package: 2225 (5763 Metric) form factor with matching physical dimensions (0.225" L × 0.250" W, 0.100" max thickness)
• Identical Temperature Coefficient: X7R dielectric material for consistent performance across -55°C to 125°C
• Identical Mounting Type: Surface mount MLCC technology
• Identical Compliance: ROHS3 compliant, MSL 1 rating, REACH unaffected status

Substitutes are differentiated by voltage rating (upgraded from 1kV to 2kV or 3kV) and tolerance (upgraded from ±20% to ±10%), representing higher performance variants within the same physical package. These upgrades maintain backward compatibility while providing enhanced voltage margin and tighter capacitance tolerance for applications requiring improved reliability.

Parameter Comparison

Engineering Selection Recommendations

All three parts—2225AC103MATBE, 2225GC103KAT1A, and 2225HC103KAT1A—are active production components from KYOCERA AVX with full ROHS3 compliance and REACH unaffected status. Selection between these parts depends on circuit voltage requirements:

• 2225AC103MATBE (1kV): Use when circuit voltage does not exceed 1000V and standard ±20% tolerance is acceptable.
• 2225GC103KAT1A (2kV): Use when circuit voltage reaches 2000V or when tighter ±10% tolerance is required for improved capacitance accuracy.
• 2225HC103KAT1A (3kV): Use when circuit voltage reaches 3000V or when maximum voltage margin and tighter tolerance are required. This variant offers the highest inventory availability (114,200 pcs).

All parts share identical physical dimensions, mounting characteristics, and temperature performance, ensuring direct PCB layout compatibility. The choice between substitutes is determined solely by the application's voltage specification and tolerance requirements.

Frequently Asked Questions (FAQ)

Q: Can 2225GC103KAT1A or 2225HC103KAT1A be used as direct replacements for 2225AC103MATBE on existing PCBs?

A: Yes. Both substitute parts maintain identical package dimensions (2225 / 5763 Metric), footprint, and mounting type (surface mount MLCC). No PCB layout modifications are required. The substitutes are physically and electrically compatible drop-in replacements.

Q: What is the difference between the ±20% tolerance of the main part and the ±10% tolerance of the substitutes?

A: Tolerance specifies the allowable deviation of actual capacitance from the nominal 10000 pF value. The main part allows ±20% deviation (8000–12000 pF range), while substitutes allow ±10% deviation (9000–11000 pF range). Tighter tolerance provides more predictable capacitance values for precision applications.

Q: Why would I choose a higher voltage-rated part if my circuit only requires 1kV?

A: Higher voltage ratings provide increased safety margin and reliability in applications subject to voltage transients, overshoot, or aging effects. The 2225HC103KAT1A (3kV) also offers superior inventory availability and tighter tolerance, making it suitable for demanding applications.

Q: Are all three parts suitable for the same temperature range?

A: Yes. All parts operate across -55°C to 125°C with X7R temperature coefficient, ensuring stable capacitance performance throughout this range.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity rating?

A: MSL 1 indicates the part has unlimited shelf life and requires no special moisture control during storage or handling. This simplifies logistics and reduces component preparation requirements compared to higher MSL ratings.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8532.24.0020) classifications.
