1808AA221MATME Equivalent & Substitute Parts

Part Overview

The 1808AA221MATME is a 220 pF ceramic capacitor rated for 1000V (1kV) with C0G/NP0 temperature coefficient, manufactured by KYOCERA AVX. This high-voltage surface-mount multilayer ceramic capacitor (MLCC) is designed for general-purpose applications requiring stable capacitance across temperature extremes (-55°C to 125°C). The part is currently active in production with 974 units in stock. Alternative models may be required when circuit designs demand higher voltage ratings, improved tolerance specifications, or different packaging configurations while maintaining the same capacitance value and form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1808AA221MATME is determined by the following critical parameters:

Fixed Parameters (Must Match):

• Capacitance: 220 pF
• Package / Case: 1808 (4520 Metric)
• Mounting Type: Surface Mount, MLCC
• Temperature Coefficient: C0G, NP0
• Operating Temperature Range: -55°C to 125°C

Variable Parameters (Allowed to Differ):

• Voltage Rating: May be equal or higher
• Tolerance: May be equal or tighter
• Thickness: May vary within mechanical constraints
• Packaging Format: May differ (bulk vs. tape & reel)

The substitute part 1808GA221JAT1A meets all fixed parameter requirements while offering enhanced voltage rating (2000V vs. 1000V) and improved tolerance (±5% vs. ±20%), making it suitable for applications requiring higher voltage margins or tighter capacitance specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808AA221MATME and 1808GA221JAT1A are active production parts from KYOCERA AVX with full ROHS3 compliance and unlimited moisture sensitivity rating. The 1808GA221JAT1A represents an upgrade path offering doubled voltage rating and tighter tolerance specification. Selection between these parts depends on circuit voltage requirements and tolerance specifications. The 1808GA221JAT1A's increased thickness (2.20mm vs. 1.45mm) must be verified against available PCB assembly clearance. Both parts maintain identical capacitance, temperature coefficient, and operating temperature range, ensuring functional compatibility in applications designed for the 1808 form factor.

Frequently Asked Questions (FAQ)

Q: Can 1808GA221JAT1A replace 1808AA221MATME in all applications?

A: The 1808GA221JAT1A is mechanically and electrically compatible as a direct substitute. The higher voltage rating (2kV vs. 1kV) and tighter tolerance (±5% vs. ±20%) make it suitable for any circuit originally designed for the 1808AA221MATME. Verify PCB clearance for the increased thickness of 2.20mm.

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

A: The 1808GA221JAT1A provides enhanced voltage rating and improved tolerance specification. Both maintain identical 220 pF capacitance, C0G/NP0 temperature coefficient, and 1808 package dimensions.

Q: Are there packaging differences between these parts?

A: The 1808AA221MATME is supplied in standard packaging, while the 1808GA221JAT1A is supplied in Tape & Reel (TR) format. Both are suitable for automated assembly processes.

Q: Do these parts have different compliance certifications?

A: Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is 1 (unlimited) for both parts.

Q: What determines whether a substitute part is acceptable?

A: Substitution is valid when capacitance, package type, temperature coefficient, and operating temperature range remain identical. Voltage rating may be equal or higher, and tolerance may be equal or tighter than the original specification.
