Key Parameters

Substitute Part Grouping Explanation

Substitution of the AMK316AC7476MLHT is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 47 µF (exact match required)
• Voltage rating: 4V (exact match required)
• Temperature coefficient: X7S (exact match required)
• Tolerance: ±20% (exact match required)

Mechanical Parameters:

• Package / Case: 1206 (3216 Metric) (exact match required)
• Mounting type: Surface Mount, MLCC (exact match required)

Compliance & Environmental Parameters:

• AEC-Q200 automotive rating (required for automotive applications)
• RoHS3 compliance (required for regulatory conformance)
• Moisture Sensitivity Level 1 (required for handling and storage compatibility)
• Operating temperature range: -55°C ~ 125°C (exact match required)

The MCASA31LAC7476MTNA01 meets all substitution criteria and is classified as an active product, making it suitable for ongoing design support and procurement.

Parameter Comparison

Engineering Selection Recommendations

The MCASA31LAC7476MTNA01 is the direct equivalent substitute for the AMK316AC7476MLHT. Both parts are manufactured by Taiyo Yuden and share identical electrical, mechanical, and environmental specifications.
