Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808SC152MATME is determined by the following critical parameters:

• Capacitance Value: Must be 1500 pF (exact match required)
• Package Designation: Must be 1808 (4520 Metric) for mechanical and electrical compatibility
• Temperature Coefficient: Must be X7R to maintain stable performance across the operating temperature range
• Mounting Type: Must be Surface Mount MLCC
• Voltage Rating: Must be equal to or greater than 1500V; higher ratings provide design margin
• Tolerance: May be equal to or tighter than ±20%
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part 1808GC152KAT1A meets all substitution criteria with identical capacitance, package, temperature coefficient, and mounting type. It provides an upgraded voltage rating of 2000V (2kV) and improved tolerance of ±10%, making it a direct functional upgrade.

Parameter Comparison

Engineering Selection Recommendations

The 1808GC152KAT1A is a direct substitute for the 1808SC152MATME. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility. The substitute part provides enhanced electrical performance through higher voltage rating (2000V versus 1500V) and tighter capacitance tolerance (±10% versus ±20%), while maintaining identical physical dimensions, package type, and temperature characteristics. Selection between these parts should be based on application voltage requirements and tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can 1808GC152KAT1A replace 1808SC152MATME in existing designs?
