Key Parameters

Substitute Part Grouping Explanation

Substitution of the T86D336M020EBAS is determined by the following electrical and mechanical parameters:

Capacitance value must remain 33 µF. Package / Case must be 2917 (7343 Metric) to ensure mechanical and electrical compatibility with existing PCB layouts. Voltage rating must be equal to or greater than 20 V to maintain circuit safety margins. ESR must be 700 mOhm or lower to preserve circuit performance characteristics. Operating temperature range must encompass -55°C to 125°C. Mounting type must be Surface Mount. Type must be Molded Tantalum.

The T83D336K025EZZS qualifies as a direct substitute based on these criteria: it maintains the 33 µF capacitance, 2917 package, 700 mOhm ESR, and -55°C to 125°C operating range. The voltage rating increases from 20 V to 25 V, providing additional safety margin. The tolerance improves from ±20% to ±10%. The part is active in production, addressing the obsolescence status of the original component.

Parameter Comparison

Engineering Selection Recommendations

The T83D336K025EZZS is the qualified substitute for the T86D336M020EBAS. Selection is based on the following factors:

The original part is obsolete, making the active T83D336K025EZZS the appropriate choice for production continuity. Both parts are manufactured by Vishay Sprague and maintain identical mechanical compatibility through the 2917 package specification. Electrical parameters are preserved: capacitance remains 33 µF, ESR remains 700 mOhm, and operating temperature range remains -55°C to 125°C. The voltage rating increases from 20 V to 25 V, providing enhanced circuit reliability. Tolerance improves from ±20% to ±10%, reducing capacitance variation in the application. Both parts carry identical RoHS non-compliance status, REACH unaffected status, and ECCN/HTSUS classifications, ensuring regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can the T83D336K025EZZS be used as a direct replacement for the T86D336M020EBAS?

A: Yes. Both parts share identical capacitance (33 µF), package (2917), ESR (700 mOhm), operating temperature range (-55°C to 125°C), and physical dimensions. The substitute features a higher voltage rating (25 V vs. 20 V) and tighter tolerance (±10% vs. ±20%), making it functionally compatible and electrically superior.

Q: What is the significance of the voltage rating increase from 20 V to 25 V?

A: The higher voltage rating provides additional safety margin in the circuit. A 25 V rated capacitor can safely operate at 20 V with reduced stress on the dielectric material, potentially extending component lifetime and improving reliability.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the T86D336M020EBAS and T83D336K025EZZS use the 2917 (7343 Metric) package with dimensions of 0.287" L x 0.169" W (7.30mm x 4.30mm) and maximum seated height of 0.122" (3.10mm). PCB layout modifications are not required.

Q: Does the tolerance improvement from ±20% to ±10% affect circuit design?

A: The tighter tolerance of the T83D336K025EZZS reduces capacitance variation, which may improve circuit performance in applications sensitive to capacitance drift. This is a beneficial characteristic that does not require design changes.

Q: Are there any compliance or certification differences?

A: Both parts share identical RoHS non-compliance status, REACH unaffected designation, and ECCN/HTSUS classifications. No compliance changes result from this substitution.
