2220AC183MAT1A Ceramic Capacitor - Equivalent & Substitute Parts

Part Overview

The 2220AC183MAT1A is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 0.018 µF and rated voltage of 1000V (1kV). This surface-mount multilayer ceramic capacitor (MLCC) operates across a temperature range of -55°C to 125°C and features X7R temperature coefficient characteristics suitable for general-purpose applications. The part maintains active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Alternative models may be required when circuit designs demand higher voltage ratings, improved tolerance specifications, or specific packaging configurations while maintaining identical physical dimensions and capacitance values.

Substitute Part Grouping Explanation

The 2220WC183KAT1A qualifies as a direct substitute for the 2220AC183MAT1A based on the following substitution criteria:

Identical Parameters:

• Capacitance: 0.018 µF (exact match)
• Temperature Coefficient: X7R (exact match)
• Operating Temperature Range: -55°C ~ 125°C (exact match)
• Package / Case: 2220 (5750 Metric) (exact match)
• Physical Dimensions: 0.224" L x 0.197" W x 0.130" max thickness (exact match)
• Mounting Type: Surface Mount, MLCC (exact match)
• RoHS Status: ROHS3 Compliant (exact match)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match)

Enhanced Parameters:

• Voltage - Rated: 2500V (2.5kV) versus 1000V (1kV) - higher voltage rating provides increased design margin
• Tolerance: ±10% versus ±20% - improved tolerance specification

The substitute part maintains full mechanical and electrical compatibility while offering superior voltage performance and tighter capacitance tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both the 2220AC183MAT1A and 2220WC183KAT1A maintain active product status with full ROHS3 compliance and REACH unaffected certification. The 2220WC183KAT1A provides enhanced design margin through its 2500V voltage rating compared to the 1000V specification of the main part, while maintaining identical physical footprint and thermal characteristics. The improved ±10% tolerance of the substitute part offers tighter capacitance control relative to the ±20% tolerance of the original specification. Both parts are suitable for general-purpose high-voltage applications within the specified operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the 2220WC183KAT1A be used as a direct replacement for the 2220AC183MAT1A?

A: Yes. Both parts share identical capacitance (0.018 µF), temperature coefficient (X7R), operating temperature range (-55°C ~ 125°C), and physical dimensions (2220 package, 5.70mm x 5.00mm x 3.30mm max). The substitute part is mechanically and electrically compatible for direct PCB substitution.

Q: What are the key differences between these two parts?

A: The primary differences are voltage rating and tolerance. The 2220WC183KAT1A is rated for 2500V (2.5kV) compared to 1000V (1kV) for the 2220AC183MAT1A, and offers ±10% tolerance versus ±20%. Both differences favor the substitute part for applications requiring higher voltage margin or tighter capacitance specification.

Q: Are there any packaging differences?

A: The substitute part 2220WC183KAT1A is specified with Tape & Reel (TR) packaging, while the main part packaging is not specified in the provided data. Both parts use the same 2220 (5750 Metric) case format and are surface-mount MLCCs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 2220AC183MAT1A and 2220WC183KAT1A are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both maintain MSL 1 (unlimited moisture sensitivity level).

Q: Which part should be selected for new designs?

A: Selection depends on circuit voltage requirements. For applications requiring 1000V operation, either part is suitable. For applications where higher voltage margin is beneficial, the 2220WC183KAT1A with its 2500V rating is the appropriate choice. The improved ±10% tolerance of the substitute part may also be preferred where tighter capacitance control is necessary.
