Key Parameters

Substitute Part Grouping Explanation

Substitution of the T86D476M016EBAS is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Capacitance value: 47 µF (exact match required)
• Package / Case: 2917 (7343 Metric) (physical and electrical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• Operating Temperature Range: -55°C to 125°C (functional envelope)
• ESR: 700 mOhm (electrical performance)

Allowable Variation Parameters:

• Voltage Rating: May be equal to or higher than 16 V (derating acceptable)
• Tolerance: May be tighter than ±20% (improved precision acceptable)

The substitute part T83D476K020EZZS meets all mandatory compatibility requirements while providing improved voltage rating (20 V vs. 16 V) and tighter tolerance (±10% vs. ±20%).

Parameter Comparison

Engineering Selection Recommendations

Frequently Asked Questions (FAQ)

Q: Can the T83D476K020EZZS be used as a direct replacement for the T86D476M016EBAS?

A: Yes. Both parts share identical capacitance (47 µF), package dimensions (2917/7343 Metric), ESR (700 mOhm), and operating temperature range (-55°C to 125°C). The substitute part is electrically and mechanically compatible for direct substitution.

Q: What is the significance of the higher voltage rating on the substitute part?

A: The T83D476K020EZZS is rated for 20 V compared to the original 16 V rating. This higher voltage rating does not affect compatibility; it provides additional derating margin and safety in the application circuit.

Q: Does the tighter tolerance of the substitute part affect circuit performance?

A: The T83D476K020EZZS features ±10% tolerance versus ±20% on the original part. Tighter tolerance improves capacitance precision and is compatible with designs specified for the original part.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts share identical RoHS non-compliance status and REACH Unaffected classification. No compliance differences exist between the two parts.

Q: What is the primary reason for substitution?

A: The T86D476M016EBAS is classified as obsolete. The T83D476K020EZZS is an active product from the same manufacturer, ensuring continued availability and supply chain support.
