Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Compatibility Parameters:

• Capacitance value: 33 µF (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 125°C (exact match required)
• Type: Molded Tantalum (exact match required)

Allowable Variation Parameters:

• Voltage Rating: Equal to or greater than 20 V
• ESR: Equal to or less than 700 mOhm
• Tolerance: ±10% (exact match)

The T83D336K025EZZS qualifies as an upgrade substitute with increased voltage rating (25 V) while maintaining all other specifications. The T83D336K020EZZL qualifies as a direct replacement with improved ESR performance (200 mOhm versus 700 mOhm) and active product status.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Performance): Select T83D336K020EZZL when maintaining the original 20 V rating is required. This part is manufacturer-recommended, carries active product status, and provides superior ESR performance (200 mOhm) compared to the obsolete T86D336K020EBAS. The improved ESR reduces heat dissipation and extends component lifetime.

For Upgraded Voltage Margin: Select T83D336K025EZZS when circuit design permits higher voltage rating. The 25 V rating provides additional safety margin in applications subject to voltage transients or supply variations. This part maintains identical ESR and all other mechanical specifications.

Both substitute parts are active products from the TANTAMOUNT™ T83 series, ensuring long-term availability and supply chain stability. Neither substitute introduces compliance changes relative to the main part; all three components share identical RoHS and REACH status.

Frequently Asked Questions (FAQ)

Q: Can T83D336K025EZZS be used in place of T86D336K020EBAS? A: Yes. The 25 V rating is compatible with 20 V circuit requirements. The higher voltage rating does not affect circuit operation and provides additional transient protection.

Q: What is the primary advantage of T83D336K020EZZL? A: The ESR is reduced from 700 mOhm to 200 mOhm, resulting in lower heat generation and improved performance in high-frequency or high-ripple-current applications. This part is manufacturer-recommended for direct replacement.

Q: Are the physical dimensions identical across all three parts? A: Yes. All three parts use the 2917 (7343 Metric) package with identical footprint dimensions: 0.287" L × 0.169" W (7.30 mm × 4.30 mm) and maximum seated height of 0.122" (3.10 mm).

Q: Does substitution require PCB layout changes? A: No. All substitute parts are surface-mount components in the same package, requiring no PCB modifications.

Q: What is the impact of obsolescence on the main part? A: The T86D336K020EBAS is classified as obsolete, indicating discontinued manufacturing. Active alternatives (T83 series) ensure continued availability and support for production and field replacement requirements.

Q: Are there compliance differences between the main part and substitutes? A: No. All three parts share identical RoHS non-compliant and REACH Unaffected status. Compliance profile remains unchanged with either substitute.
