KYOCERA AVX 2225WC103MAT1A Equivalent & Substitute Parts

Part Overview

The KYOCERA AVX 2225WC103MAT1A is a high-voltage ceramic capacitor rated at 10000 pF with 2500V (2.5kV) operating voltage and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 2225 package format is designed for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating temperature range. The part is ROHS3 compliant and REACH unaffected, with MSL 1 rating indicating unlimited moisture sensitivity protection. Equivalent and substitute parts are identified to support procurement flexibility, inventory optimization, and design continuity when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 2225WC103MAT1A are identified based on strict electrical and mechanical compatibility criteria. The primary substitution parameters are:

• Capacitance value: 10000 pF (exact match required)
• Temperature coefficient: X7R (ensures stable performance across operating range)
• Package format: 2225 (5763 Metric) (ensures PCB footprint compatibility)
• Mounting type: Surface Mount, MLCC (ensures assembly process compatibility)
• Operating temperature range: -55°C to 125°C (ensures thermal performance match)
• Compliance standards: ROHS3 and REACH status (ensures regulatory alignment)

Voltage rating and tolerance are secondary parameters that may vary within acceptable design margins. Substitute parts with equal or higher voltage ratings maintain backward compatibility. Tolerance variations (±20% to ±10%) are acceptable when circuit design permits, as tighter tolerances provide improved performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full compatibility with the 2225WC103MAT1A across all critical mechanical and thermal parameters. Selection between substitutes depends on specific circuit requirements:

The 2225HC103KAT1A provides upgraded voltage rating at 3000V (3kV) with improved tolerance specification (±10%), offering enhanced performance margin for high-voltage applications. This part is suitable when circuit design permits higher voltage-rated components and when tighter capacitance tolerance improves overall system performance.

The 2225WC103KAT1A maintains identical voltage rating (2500V) and temperature coefficient (X7R) as the main part while providing improved tolerance specification (±10%). This part is the manufacturer-recommended direct replacement when voltage rating and tolerance requirements align with the original specification.

All three parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 rating, ensuring regulatory compliance and assembly process compatibility. Product status is Active for all parts, confirming long-term availability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can 2225HC103KAT1A be used as a direct replacement for 2225WC103MAT1A?

A: Yes. The 2225HC103KAT1A is electrically and mechanically compatible. It maintains identical capacitance (10000 pF), temperature coefficient (X7R), package format (2225), and operating temperature range (-55°C to 125°C). The higher voltage rating (3000V vs 2500V) and tighter tolerance (±10% vs ±20%) represent performance improvements that do not compromise backward compatibility.

Q: What is the difference between ±20% and ±10% tolerance?

A: Tolerance specifies the allowable deviation of actual capacitance from the nominal value. The 2225WC103MAT1A permits ±20% deviation (8000 pF to 12000 pF), while substitute parts with ±10% tolerance permit ±10% deviation (9000 pF to 11000 pF). Tighter tolerance provides more precise capacitance values, beneficial for circuits requiring strict capacitance specifications.

Q: Are all three parts available in the same packaging format?

A: The 2225WC103MAT1A is supplied in standard packaging. The 2225HC103KAT1A and 2225WC103KAT1A are supplied in Tape & Reel (TR) format. Both packaging formats are compatible with automated assembly processes. Verify packaging requirements with your procurement or assembly department before part selection.

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

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements. All parts carry MSL 1 rating, indicating unlimited moisture sensitivity protection suitable for standard storage and handling conditions.

Q: Which substitute part should be selected for new designs?

A: Selection depends on circuit voltage and tolerance requirements. For applications requiring 2500V rating with standard tolerance, the 2225WC103KAT1A is the manufacturer-recommended choice. For applications permitting higher voltage ratings or requiring tighter tolerance, the 2225HC103KAT1A provides enhanced performance characteristics.
