• Electrical Compatibility: Identical capacitance, ESR, and operating temperature range preserve circuit performance.
• Mechanical Compatibility: Identical package dimensions and mounting type enable direct PCB footprint compatibility without layout modification.
• Performance Enhancement: The 20 V rating provides increased voltage margin over the original 10 V specification, and the ±10% tolerance offers improved capacitance accuracy.
• Compliance Alignment: Both parts maintain identical RoHS and REACH status, preserving regulatory consistency in the design.

Frequently Asked Questions (FAQ)

Q: Can the T83D476K020EZZS be used as a direct replacement for the T86D476M010ESSS?

A: Yes. Both components share identical capacitance (47 µF), package format (2917), ESR (700 mOhm), and physical dimensions. The substitute is mechanically and electrically compatible with the original design without PCB modification.

Q: What is the significance of the higher 20 V rating on the substitute part?

A: The substitute's 20 V rating provides a 2:1 voltage safety margin compared to the original 10 V specification. This enhanced margin improves reliability and operational headroom in the circuit without affecting performance at the original operating voltage.

Q: Does the improved ±10% tolerance on the substitute part affect circuit design?

A: The tighter ±10% tolerance on the substitute provides improved capacitance accuracy compared to the original ±20% specification. This enhancement does not negatively impact the original design and may improve circuit performance in applications sensitive to capacitance variation.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts maintain identical RoHS non-compliance status and REACH unaffected classification. No compliance changes occur with substitution.

Q: What is the primary reason for substitution?

A: The T86D476M010ESSS is classified as obsolete. The T83D476K020EZZS is the active production equivalent, ensuring continued availability and supply chain stability.
