Key Parameters

Substitute Part Grouping Explanation

Substitution of the T86D336M016EBAL is determined by the following critical parameters:

• Capacitance Value: Must be 33 µF
• Tolerance: Must be ±20%
• Package / Case: Must be 2917 (7343 Metric)
• Mounting Type: Must be Surface Mount
• Operating Temperature Range: Must support -55°C ~ 125°C
• Voltage Rating: Must be equal to or greater than 16 V
• Type: Must be Molded Tantalum

The TAWD336M020R0500 from KYOCERA AVX meets all substitution criteria. It maintains identical capacitance, tolerance, package dimensions, and operating temperature specifications while providing a higher voltage rating of 20 V, which is compatible with 16 V circuit requirements.

Engineering Selection Recommendations

The TAWD336M020R0500 is the qualified substitute for the obsolete T86D336M016EBAL. Selection is based on the following engineering criteria:

• Product Status: The substitute part is active and currently available, addressing the obsolescence of the original component.
• Functional Equivalence: Identical capacitance, tolerance, package, and thermal operating range ensure direct circuit compatibility.
• Voltage Margin: The 20 V rating provides a 25% safety margin above the 16 V requirement, which is acceptable for applications designed for 16 V operation.
• Compliance: The substitute part is ROHS3 compliant, meeting modern regulatory requirements, whereas the original part is RoHS non-compliant.
• Physical Compatibility: Identical package dimensions and height specifications ensure PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the TAWD336M020R0500 be used as a direct replacement for the T86D336M016EBAL?

A: Yes. The substitute part maintains identical capacitance (33 µF), tolerance (±20%), package (2917), and operating temperature range (-55°C ~ 125°C). The higher voltage rating (20 V vs. 16 V) is compatible with circuits designed for 16 V operation.

Q: What is the difference in ESR between the two parts?

A: The original part has an ESR of 350 mOhm, while the substitute has an ESR of 500 mOhm. This 150 mOhm difference may affect high-frequency ripple current performance in sensitive applications. Circuit validation is recommended if ESR is a critical design parameter.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 2917 (7343 Metric) package 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.

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

A: A 20 V rated capacitor can be safely used in a 16 V circuit. The higher voltage rating provides design margin and does not negatively impact circuit performance. This is standard practice in component substitution.

Q: Are both parts moisture sensitive?

A: Both parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard handling procedures apply to both components.

Q: Does the substitute part meet current regulatory standards?

A: Yes. The TAWD336M020R0500 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original T86D336M016EBAL is RoHS non-compliant.
