Equivalent & Substitute Parts for T86D476K016EBAS

Part Overview

The T86D476K016EBAS is a 47 µF molded tantalum capacitor rated at 16 V with a 2917 (7343 Metric) package form factor. Manufactured by Vishay Sprague under the TANTAMOUNT™ T86 series, this component is classified as obsolete. Due to its discontinued status, equivalent and substitute parts from active product lines are necessary for new designs and ongoing production requirements. Suitable alternatives maintain the same capacitance, tolerance, voltage rating, and package dimensions while offering improved electrical characteristics or active manufacturing status.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the T86D476K016EBAS is determined by strict adherence to the following electrical and mechanical parameters:

• Capacitance: Must be 47 µF
• Tolerance: Must be ±10%
• Voltage Rating: Minimum 16 V (higher voltage ratings are acceptable for direct substitution)
• Package / Case: Must be 2917 (7343 Metric)
• Type: Must be molded tantalum
• Mounting Type: Must be surface mount
• Operating Temperature Range: Must support -55°C to 125°C
• Moisture Sensitivity Level: Must be MSL 1 or equivalent

All substitute parts listed meet these criteria. Variations in ESR (Equivalent Series Resistance) do not preclude substitution but may affect circuit performance in applications with specific impedance requirements.

Parameter Comparison

Engineering Selection Recommendations

T83D476K016EZZL (Vishay Sprague, Active): This part is the manufacturer-recommended direct equivalent. It maintains identical electrical specifications to the T86D476K016EBAS while offering active product status and improved ESR performance (150 mOhm versus 700 mOhm). Selection of this part is appropriate for applications where lower impedance is beneficial and Vishay Sprague sourcing is preferred.

T83D476K020EZZS (Vishay Sprague, Active): This part provides a voltage rating upgrade to 20 V while maintaining all other specifications. It is suitable for applications where higher voltage margin is desired or where circuit redesign permits the use of a higher-rated component. ESR remains at 700 mOhm, matching the original part.

TBJD476K016LBSB0024 (KYOCERA AVX, Active): This part offers the lowest ESR specification at 80 mOhm, making it suitable for applications with stringent impedance requirements. It maintains the 16 V rating and all mechanical compatibility with the original part. Selection of this part introduces a secondary source from KYOCERA AVX.

All substitute parts maintain compliance with REACH regulations and MSL 1 moisture sensitivity classification. RoHS non-compliance status is consistent across all options.

Frequently Asked Questions (FAQ)

Q: Can T83D476K016EZZL be used as a direct replacement for T86D476K016EBAS?

A: Yes. Both parts share identical capacitance (47 µF), tolerance (±10%), voltage rating (16 V), package (2917), and operating temperature range (-55°C to 125°C). The T83D476K016EZZL offers improved ESR performance and active manufacturing status.

Q: What is the difference between T83D476K020EZZS and T83D476K016EZZL?

A: The primary difference is voltage rating: T83D476K020EZZS is rated at 20 V, while T83D476K016EZZL is rated at 16 V. Both maintain 47 µF capacitance and ±10% tolerance. The 20 V variant provides additional voltage margin for applications requiring higher safety factors.

Q: Is TBJD476K016LBSB0024 compatible with the original T86D476K016EBAS?

A: Yes. TBJD476K016LBSB0024 meets all substitution criteria: 47 µF capacitance, ±10% tolerance, 16 V rating, 2917 package, and -55°C to 125°C operating range. It is manufactured by KYOCERA AVX and offers superior ESR performance at 80 mOhm.

Q: Does ESR variation affect substitution compatibility?

A: ESR does not preclude substitution when all other electrical and mechanical parameters match. However, applications with specific impedance requirements or ripple current specifications should evaluate ESR differences. Lower ESR values (80 mOhm, 150 mOhm) generally provide improved performance compared to higher values (700 mOhm).

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts use 2917 (7343 Metric) package with identical dimensions (0.287" L x 0.169" W, 7.30mm x 4.30mm) and maximum seated height (0.122", 3.10mm). Surface mount compatibility is maintained across all options.

Q: What is the manufacturing status of each substitute part?

A: T83D476K016EZZL and T83D476K020EZZS are active Vishay Sprague products. TBJD476K016LBSB0024 is an active KYOCERA AVX product. The original T86D476K016EBAS is obsolete and no longer manufactured.
