Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1808AC153MAT1A is determined by the following critical parameters:

• Capacitance Value: Must be 0.015 µF (no deviation permitted)
• Voltage Rating: Must be 1000V (1kV) or higher
• Temperature Coefficient: Must be X7R for consistent performance across the operating temperature range
• Package / Case: Must be 1808 (4520 Metric) for mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount, MLCC
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The 1808AC153KAT1A qualifies as a direct substitute based on these parameters. The primary difference is the tolerance specification: the substitute part features ±10% tolerance compared to the main part's ±20% tolerance, representing an upgrade in capacitance accuracy while maintaining all other critical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 1808AC153MAT1A and 1808AC153KAT1A are active production parts with full ROHS3 compliance and identical mechanical compatibility. Selection between these parts depends on application-specific tolerance requirements:

• 1808AC153MAT1A: Select when ±20% capacitance tolerance is acceptable for the circuit design
• 1808AC153KAT1A: Select when tighter ±10% capacitance tolerance is required for improved circuit performance or when higher accuracy is specified in design requirements

Both parts maintain identical voltage ratings, temperature coefficients, and physical dimensions, ensuring direct interchangeability at the board level. The substitute part represents an upgrade path for applications requiring enhanced capacitance accuracy without design modification.

Frequently Asked Questions (FAQ)
