Key Parameters

Substitute Part Grouping Explanation

Substitution of the T86D336M016EBAS is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Capacitance value: 33 µF (exact match required)
• Package / Case: 2917 (7343 Metric) (physical and electrical compatibility)
• Mounting Type: Surface Mount (assembly compatibility)
• ESR: 700 mOhm (electrical performance equivalence)
• Operating Temperature Range: -55°C to 125°C (thermal compatibility)

Allowable Variation Parameters:

• Voltage Rating: Must be equal to or greater than 16 V (higher voltage ratings provide design margin)
• Tolerance: May be tighter than ±20% (improved accuracy is acceptable)

The T83D336K025EZZS qualifies as a direct substitute based on these criteria, offering identical capacitance, package, ESR, and operating temperature specifications while providing an upgraded voltage rating of 25 V and improved tolerance of ±10%.

Parameter Comparison

Engineering Selection Recommendations

The T83D336K025EZZS is the qualified substitute for the obsolete T86D336M016EBAS. Selection is supported by the following factors:

Product Status: The T83D336K025EZZS maintains active product status, ensuring continued availability and manufacturing support, whereas the main part is obsolete.

Electrical Compatibility: The substitute provides identical capacitance (33 µF), ESR (700 mOhm), and operating temperature range (-55°C to 125°C). The increased voltage rating of 25 V versus 16 V provides additional design margin without compromising circuit functionality.

Tolerance Improvement: The ±10% tolerance of the substitute is tighter than the ±20% tolerance of the main part, offering improved capacitance accuracy.

Physical Compatibility: Both parts share identical package dimensions (2917 / 7343 Metric), height specifications, and surface mount mounting type, ensuring direct PCB compatibility without layout modifications.

Compliance Alignment: Both parts maintain identical RoHS non-compliance status and MSL rating (1 / Unlimited), preserving compliance posture in designs where these specifications are relevant.

Frequently Asked Questions (FAQ)

Q: Can the T83D336K025EZZS be used as a direct replacement for the T86D336M016EBAS?

A: Yes. Both parts share identical capacitance (33 µF), package (2917 / 7343 Metric), ESR (700 mOhm), and operating temperature range (-55°C to 125°C). The substitute features a higher voltage rating (25 V vs. 16 V) and tighter tolerance (±10% vs. ±20%), both of which are compatible with applications designed for the original part.

Q: What is the significance of the voltage rating difference?

A: The T83D336K025EZZS is rated for 25 V operation compared to the 16 V rating of the T86D336M016EBAS. A higher voltage rating provides additional design margin and does not negatively impact circuits designed for lower voltages. The substitute will operate safely in any application where the original 16 V part was specified.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in the 2917 (7343 Metric) case with identical length (0.287" / 7.30mm), width (0.169" / 4.30mm), and maximum seated height (0.122" / 3.10mm). No PCB layout modifications are required for substitution.

Q: Does the tolerance difference affect circuit performance?

A: The T83D336K025EZZS offers ±10% tolerance compared to ±20% for the original part. Tighter tolerance improves capacitance accuracy and may enhance circuit performance in applications sensitive to capacitance variation. This represents an upgrade rather than a compromise.

Q: Are there any compliance or certification differences?

A: Both parts maintain identical RoHS non-compliance status and MSL rating (1 / Unlimited). No compliance changes result from substitution.

Q: What is the ESR equivalence between these parts?

A: Both parts specify 700 mOhm ESR, ensuring identical electrical performance characteristics in high-frequency and transient response applications.
