Key Parameters

Substitute Part Grouping Explanation

Substitution for the T86E476K020ESSL is determined by strict equivalence in the following parameters: capacitance (47 µF), tolerance (±10%), package (2917/7343 Metric), mounting type (surface mount), and operating temperature range (-55°C to 125°C). Voltage rating and ESR are the primary variables that define substitution categories.

Substitute parts are grouped into three categories:

Upgrade Category: Parts with identical capacitance and tolerance but higher voltage rating (25 V vs. 20 V), providing enhanced voltage margin while maintaining package compatibility.

Manufacturer Recommended Category: Vishay Sprague T83 series parts with identical electrical specifications (47 µF, 20 V, ±10%) but variations in ESR or physical height, offering active product status as direct replacements.

Direct Equivalent Category: KEMET T496X476K020ATE300 with identical electrical and mechanical specifications (47 µF, 20 V, 300 mOhm ESR, 2917 package), providing cross-manufacturer compatibility with RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement with Active Product Status: T83E476K020EZZL is the primary recommendation. This Vishay Sprague part maintains identical electrical specifications (47 µF, 20 V, ±10% tolerance) with lower ESR (150 mOhm vs. 300 mOhm), providing improved performance characteristics. Active product status ensures long-term availability and supply chain continuity.

For Voltage Margin Enhancement: T83E476K025EZZL provides a 25 V rating while maintaining 47 µF capacitance and 300 mOhm ESR. This upgrade is suitable for applications requiring additional voltage headroom without circuit redesign.

For Cross-Manufacturer Compatibility: T496X476K020ATE300 (KEMET) offers identical electrical and mechanical specifications with RoHS3 compliance, addressing environmental and regulatory requirements. This part is recommended for new designs requiring RoHS compliance.

For Space-Constrained Applications: T83D476K020EZZS provides the lowest profile (0.122" seated height) with identical voltage and capacitance ratings, though ESR is elevated to 700 mOhm. Selection depends on circuit tolerance for increased series resistance.

All substitute parts maintain MSL 1 (Unlimited) moisture sensitivity and -55°C to 125°C operating temperature range, ensuring compatibility with existing assembly and storage processes.

Frequently Asked Questions (FAQ)

Q: Can T83E476K020EZZL replace T86E476K020ESSL directly? A: Yes. Both parts share identical capacitance (47 µF), voltage rating (20 V), tolerance (±10%), and package (2917). The T83E476K020EZZL features lower ESR (150 mOhm vs. 300 mOhm), which improves performance. Active product status makes this the recommended replacement.

Q: What is the difference between the T83E476K020EZZL and T83D476K020EZZS? A: Both are 47 µF, 20 V, ±10% tolerance parts in the 2917 package. The primary differences are ESR (150 mOhm vs. 700 mOhm) and seated height (0.170" vs. 0.122"). The T83D variant is suitable for space-constrained designs but has higher series resistance.

Q: Is T83E476K025EZZL compatible with circuits designed for 20 V? A: Yes. The T83E476K025EZZL is rated for 25 V, which exceeds the 20 V requirement. It maintains identical capacitance (47 µF), tolerance (±10%), ESR (300 mOhm), and package (2917), providing enhanced voltage margin without affecting circuit operation.

Q: Why is T496X476K020ATE300 recommended for new designs? A: The KEMET T496X476K020ATE300 provides identical electrical specifications (47 µF, 20 V, 300 mOhm ESR) with RoHS3 compliance. This addresses environmental regulations and ensures long-term supply availability for new product development.

Q: Are all substitute parts compatible with existing PCB layouts? A: Yes. All substitute parts use the 2917 (7343 Metric) package with surface mount configuration. Seated heights vary slightly (0.122" to 0.170"), but all remain within standard PCB assembly tolerances. Verify height clearance for space-constrained applications.

Q: What is the impact of ESR differences between substitute parts? A: ESR affects ripple current handling and thermal performance. Lower ESR (150 mOhm in T83E476K020EZZL) improves efficiency; higher ESR (700 mOhm in T83D476K020EZZS) may increase heat generation. Select based on circuit ripple current requirements and thermal constraints.

Q: Can I use these parts interchangeably in production? A: Parts within the same electrical specification group (47 µF, 20 V, ±10%) are interchangeable from a functional standpoint. However, verify ESR and height specifications against circuit requirements and PCB layout constraints before implementing production changes.
