Key Parameters

Substitute Part Grouping Explanation

Substitution of the T520L337M2R5ATE009 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 330 µF
• Voltage Rating: 2.5 V
• Package / Case: 2312 (6032 Metric)
• Type: Molded Tantalum Polymer
• Mounting Type: Surface Mount
• Operating Temperature Range: -55°C ~ 105°C
• Tolerance: ±20%

Allowable Variation:

• ESR (Equivalent Series Resistance) at 100 kHz may vary within the active product specifications
• Product status may differ (obsolete to active transition)

Two substitute parts meet these criteria: T520L337M2R5ATE025 and T520L337M2R5ATE0097650. Both maintain identical capacitance, voltage, package, and thermal specifications while differing only in ESR characteristics.

Parameter Comparison

Engineering Selection Recommendations

T520L337M2R5ATE0097650 is the primary parametric equivalent, offering identical ESR characteristics (9 mOhm @ 100 kHz) to the original T520L337M2R5ATE009 while maintaining active product status. This part provides direct functional replacement with no performance trade-offs and is recommended for applications where ESR-sensitive circuit performance is critical.

T520L337M2R5ATE025 serves as an alternative substitute with higher ESR (25 mOhm @ 100 kHz). This part is suitable for applications where ESR variation within the 25 mOhm specification does not impact circuit performance. Both substitute parts carry ROHS3 compliance and active manufacturing status, ensuring long-term supply chain availability.

Selection between the two substitutes depends on circuit requirements regarding ESR tolerance and ripple current handling. Applications with strict ESR requirements should utilize T520L337M2R5ATE0097650. Applications with relaxed ESR specifications may use T520L337M2R5ATE025.

Frequently Asked Questions (FAQ)

Q: Can T520L337M2R5ATE025 replace T520L337M2R5ATE009 in all applications?

A: T520L337M2R5ATE025 is electrically compatible for applications where the higher ESR (25 mOhm versus 9 mOhm) does not exceed circuit design limits. ESR affects ripple current handling and thermal performance. Verify circuit specifications before substitution.

Q: What is the primary difference between the two substitute parts?

A: T520L337M2R5ATE0097650 and T520L337M2R5ATE025 differ only in ESR at 100 kHz (9 mOhm versus 25 mOhm). All other electrical and mechanical parameters are identical.

Q: Are the substitute parts physically interchangeable with the original?

A: Yes. Both substitute parts use the identical 2312 (6032 Metric) package with matching dimensions (0.236" L x 0.126" W, 6.00mm x 3.20mm) and maximum seated height (0.075", 1.90mm). Surface mount footprints are identical.

Q: Why is the original part obsolete?

A: Product status reflects KEMET's manufacturing decisions. The substitute parts T520L337M2R5ATE0097650 and T520L337M2R5ATE025 maintain active status and provide equivalent functionality.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both substitute parts are ROHS3 compliant and REACH unaffected, matching the original part's regulatory status.

Q: What is Moisture Sensitivity Level 3?

A: MSL 3 indicates the component requires controlled storage conditions with a maximum floor life of 168 hours at 30°C and 60% relative humidity after exposure to moisture. Proper handling and storage procedures apply to all three parts.
