Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F320E337MCC is determined by strict alignment across the following parameters:

• Capacitance Value: 330 µF (±20% tolerance acceptable)
• Voltage Rating: 2.5 V minimum
• Package / Case: 2312 (6032 Metric) surface mount
• Type: Molded tantalum polymer construction
• Operating Temperature Range: -55°C to 105°C minimum coverage
• Mounting Configuration: Surface mount only

The KEMET T520L337M2R5ATE025 meets all substitution criteria. Both parts share identical capacitance, voltage rating, package geometry, and temperature operating range. The substitute part is currently in active production status, ensuring long-term availability.

Parameter Comparison

Engineering Selection Recommendations

The T520L337M2R5ATE025 is a direct functional equivalent to the F320E337MCC. Both components satisfy identical electrical and mechanical specifications for the 330 µF, 2.5 V, 2312 package category. The KEMET substitute offers the advantage of active production status, ensuring procurement availability and supply chain continuity.

The T520L337M2R5ATE025 exhibits a lower ESR value (25 mOhm versus 55 mOhm), which represents an improvement in performance characteristics. The seated height difference (1.90mm versus 2.70mm) must be evaluated against PCB layout constraints; the lower profile of the substitute may provide design flexibility in space-constrained applications.

Both parts maintain REACH compliance and EAR99 export classification. The substitute carries RoHS3 compliance certification.

Frequently Asked Questions (FAQ)

Q: Can the T520L337M2R5ATE025 replace the F320E337MCC in existing designs?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (2.5 V), package geometry (2312 / 6032 Metric), and operating temperature range (-55°C to 105°C). The substitute is a direct replacement from an electrical and mechanical standpoint.

Q: What is the significance of the ESR difference between these parts?

A: The T520L337M2R5ATE025 has a lower ESR (25 mOhm) compared to the F320E337MCC (55 mOhm). Lower ESR generally reduces heat generation and improves transient response characteristics. This represents a performance enhancement rather than a limitation.

Q: Does the height difference affect PCB compatibility?

A: The T520L337M2R5ATE025 has a maximum seated height of 1.90mm, compared to 2.70mm for the F320E337MCC. The substitute is physically lower, which may provide additional clearance in space-constrained designs. PCB layout and component placement must be verified against specific board constraints.

Q: Are there supply chain advantages to using the KEMET substitute?

A: Yes. The T520L337M2R5ATE025 is in active production status, whereas the F320E337MCC is obsolete. The active status ensures long-term availability and reduces procurement risk.

Q: Do both parts meet the same compliance standards?

A: Both parts are REACH Unaffected and classified as EAR99 for export purposes. The KEMET substitute additionally carries RoHS3 compliance certification.
