Equivalent & Substitute Parts for 2220CC183MAT1A

Part Overview

The 2220CC183MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX, rated at 0.018 µF with 630V operating voltage and X7R temperature coefficient. This surface-mount multilayer ceramic capacitor (MLCC) in 2220 package format is designed for general-purpose applications requiring stable capacitance across the -55°C to 125°C operating range. 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 specifications are maintained while offering enhanced electrical performance or improved tolerance characteristics.

Substitute Part Grouping Explanation

Substitution for the 2220CC183MAT1A is based on maintaining identical capacitance (0.018 µF), temperature coefficient (X7R), package format (2220), and mounting technology (surface-mount MLCC). The substitute part 2220WC183KAT1A qualifies as a direct substitute because it preserves all critical functional parameters while offering enhanced electrical performance through increased voltage rating (2500V versus 630V) and improved tolerance (±10% versus ±20%). Both parts maintain identical physical dimensions, operating temperature range, and regulatory compliance status. The voltage rating increase represents an upgrade path suitable for applications requiring higher voltage margin or operating in elevated voltage environments while maintaining the same footprint and thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 2220WC183KAT1A serves as a qualified substitute for the 2220CC183MAT1A in applications where the original 630V rating is sufficient. Both parts maintain active production status with identical regulatory compliance (ROHS3, REACH Unaffected). The substitute part offers improved tolerance specification (±10% versus ±20%), which may benefit circuits requiring tighter capacitance control. The elevated voltage rating of the substitute (2500V) provides additional design margin without affecting physical footprint, thermal performance, or moisture sensitivity characteristics. Selection between these parts depends on circuit voltage requirements and tolerance specifications rather than functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can 2220WC183KAT1A replace 2220CC183MAT1A in existing designs?

A: Yes. Both parts share identical capacitance (0.018 µF), temperature coefficient (X7R), package format (2220), and physical dimensions. The substitute operates at higher voltage rating (2500V versus 630V) and tighter tolerance (±10% versus ±20%), making it functionally compatible for direct substitution in the same PCB footprint.

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

A: The main differences are voltage rating and tolerance. The 2220WC183KAT1A provides 2500V rating compared to 630V in the original part, and maintains ±10% tolerance versus ±20%. Capacitance value, package size, and operating temperature range remain identical.

Q: Are there any packaging differences?

A: The 2220CC183MAT1A is specified with standard packaging, while the 2220WC183KAT1A is supplied in Tape & Reel (TR) format. Both maintain identical component dimensions and mounting characteristics for surface-mount assembly.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) rating. Regulatory compliance is equivalent between the two parts.

Q: Which part should be selected for new designs?

A: Selection depends on circuit voltage requirements. If the application operates at or below 630V, either part is suitable. For applications requiring higher voltage margin or operating in elevated voltage environments, the 2220WC183KAT1A is the appropriate choice. The improved tolerance of the substitute may also benefit circuits requiring tighter capacitance control.
