1808SC221MATME Equivalent & Substitute Parts

Part Overview

The 1808SC221MATME is a high-voltage ceramic capacitor manufactured by KYOCERA AVX with a capacitance of 220 pF and rated voltage of 1500V (1.5kV). This surface-mount multilayer ceramic capacitor (MLCC) features X7R temperature coefficient and is designed for general-purpose applications requiring high-voltage performance. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance can be achieved through alternative manufacturers or improved specifications while maintaining mechanical compatibility.

Substitute Part Grouping Explanation

The 1808GA221JAT1A qualifies as a substitute for the 1808SC221MATME based on the following substitution criteria:

Matching Parameters:

• Capacitance: 220 pF (identical)
• Package / Case: 1808 (4520 Metric) (identical)
• Size / Dimension: 0.181" L x 0.079" W (4.60mm x 2.00mm) (identical)
• Mounting Type: Surface Mount, MLCC (identical)
• Operating Temperature Range: -55°C ~ 125°C (identical)
• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (identical)
• Manufacturer: KYOCERA AVX (identical)
• Product Status: Active (identical)

Upgraded Parameters:

• Voltage - Rated: 2000V (2kV) versus 1500V (1.5kV) — higher voltage rating provides enhanced margin
• Tolerance: ±5% versus ±20% — tighter tolerance specification
• Temperature Coefficient: C0G, NP0 versus X7R — more stable temperature performance

The substitute part maintains identical mechanical compatibility and all critical compliance certifications while offering improved electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808SC221MATME and 1808GA221JAT1A are active production parts from KYOCERA AVX with ROHS3 compliance and unlimited moisture sensitivity rating. The parts are mechanically interchangeable within the 1808 (4520 Metric) footprint.

The 1808GA221JAT1A offers improved electrical specifications with a higher voltage rating (2000V versus 1500V) and tighter capacitance tolerance (±5% versus ±20%). The C0G/NP0 temperature coefficient provides superior temperature stability compared to X7R. The increased thickness (0.087" versus 0.071") remains within typical PCB assembly tolerances for surface-mount components.

Selection between these parts depends on circuit voltage requirements and tolerance specifications. The substitute part is suitable for applications where the original part is specified, provided that the increased thickness does not conflict with board-level clearance constraints.

Frequently Asked Questions (FAQ)

Q: Can the 1808GA221JAT1A directly replace the 1808SC221MATME on a PCB?

A: Yes. Both parts use the 1808 (4520 Metric) package with identical footprint dimensions (0.181" L x 0.079" W). The substitute part has a maximum thickness of 0.087" compared to 0.071" for the original part. Verify that board-level clearance accommodates the increased thickness before assembly.

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

A: The primary differences are voltage rating (2000V versus 1500V), capacitance tolerance (±5% versus ±20%), and temperature coefficient (C0G/NP0 versus X7R). The substitute part provides higher voltage margin and tighter tolerance specifications while maintaining identical capacitance value and operating temperature range.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1808SC221MATME and 1808GA221JAT1A are ROHS3 compliant with unlimited moisture sensitivity (MSL 1).

Q: Which part should be used for new designs?

A: Selection is based on circuit requirements. If the application requires 1500V rating, the 1808SC221MATME is appropriate. If higher voltage margin or tighter tolerance is beneficial, the 1808GA221JAT1A is suitable. Both parts are active in production.

Q: What is the difference between X7R and C0G/NP0 temperature coefficients?

A: X7R provides ±15% capacitance change over the -55°C to 125°C temperature range. C0G/NP0 provides superior stability with minimal capacitance change across temperature. C0G/NP0 is preferred for applications requiring stable capacitance performance across temperature extremes.
