Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1825AC473MATME is determined by the following critical parameters:

• Capacitance Value: Must be 0.047 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 Format: Must be 1825 (4564 Metric) to ensure mechanical and electrical compatibility
• Mounting Type: Must be Surface Mount MLCC
• Physical Dimensions: Must match 4.50mm L × 6.40mm W footprint and 2.54mm maximum thickness
• Compliance Standards: Must maintain ROHS3 compliance and MSL 1 rating

The 1825AC473KAT1A qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. The primary distinction is the capacitance tolerance specification, which is tighter (±10%) compared to the main part (±20%), representing an upgrade in precision without affecting substitution compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the 1825AC473MATME and 1825AC473KAT1A are Active products manufactured by KYOCERA AVX with full ROHS3 compliance and REACH Unaffected status. Selection between these parts should be based on the following criteria:

1825AC473MATME is appropriate for applications where standard ±20% capacitance tolerance meets circuit requirements and cost optimization is a priority. Current inventory of 967 units supports immediate availability.

1825AC473KAT1A is suitable for applications requiring tighter capacitance tolerance control (±10%), offering improved precision in high-voltage filtering, coupling, or timing circuits. This part is available in Tape & Reel packaging with 2300 units in stock, supporting higher-volume production requirements.

Both parts satisfy identical electrical performance specifications, mechanical compatibility, and regulatory compliance requirements. The choice between them depends on tolerance requirements and packaging format needs rather than functional capability.

Frequently Asked Questions (FAQ)

Q: Can 1825AC473KAT1A replace 1825AC473MATME in existing designs?
