Substitute Part Grouping Explanation

Substitution of the T520V477M2R5ASE015 is determined by strict equivalence across the following critical parameters:

  • Capacitance Value: 470 µF (exact match required)
  • Voltage Rating: 2.5 V (exact match required)
  • Package / Case: 2917 (7343 Metric) (exact match required)
  • ESR @ 100kHz: 15 mOhm (exact match required)
  • Operating Temperature Range: -55°C to 105°C (exact match required)
  • Mounting Type: Surface Mount (exact match required)
  • Type: Molded Tantalum Polymer (exact match required)

The substitute part T520V477M2R5ATE015 meets all critical electrical and mechanical parameters. The primary distinction between the main part and its substitute is the packaging format and product status. The substitute part is supplied in Tape & Reel (TR) format and maintains active product status, whereas the main part is obsolete and supplied in standard packaging.

Engineering Selection Recommendations

The T520V477M2R5ATE015 is the direct substitute for the obsolete T520V477M2R5ASE015. Both components are manufactured by KEMET within the same KO-CAP® T520 series and share identical electrical specifications and mechanical dimensions.

Product Status Consideration: The substitute part maintains active product status, ensuring ongoing availability and supply chain continuity. The main part is obsolete and subject to limited inventory availability.

Compliance Status: The substitute part is RoHS3 compliant, whereas the main part is RoHS non-compliant. Applications requiring RoHS compliance must utilize the substitute part.

Packaging Format: The substitute part is supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly operations. The main part is supplied in standard packaging. Selection between these formats depends on production volume and assembly equipment capabilities.

Electrical and Mechanical Equivalence: All critical parameters—capacitance, voltage rating, ESR, operating temperature range, package dimensions, and mounting type—are identical between the main part and substitute. Direct substitution is electrically and mechanically valid.

Frequently Asked Questions (FAQ)

Q: Can the T520V477M2R5ATE015 be used as a direct replacement for the T520V477M2R5ASE015?

A: Yes. Both components are electrically and mechanically equivalent. They share identical capacitance (470 µF), voltage rating (2.5 V), ESR (15 mOhm @ 100kHz), operating temperature range (-55°C to 105°C), and package dimensions (2917 / 7343 Metric). The substitute part is suitable for direct substitution in all applications.

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

A: The main differences are product status and packaging format. The T520V477M2R5ASE015 is obsolete and supplied in standard packaging. The T520V477M2R5ATE015 is active and supplied in Tape & Reel (TR) format. Additionally, the substitute part is RoHS3 compliant, while the main part is RoHS non-compliant.

Q: Does the Tape & Reel packaging affect circuit performance?

A: No. Tape & Reel packaging is a supply and handling format used for automated assembly operations. It does not affect the electrical or mechanical performance of the capacitor. The component itself is identical.

Q: Are there any temperature or voltage derating considerations when substituting?

A: No. Both parts operate across the identical temperature range (-55°C to 105°C) and are rated for the same voltage (2.5 V). No derating adjustments are required.

Q: What is the MSL rating, and does it differ between these parts?

A: Both parts carry an MSL (Moisture Sensitivity Level) rating of 3, with a floor life of 168 hours. Handling and storage procedures are identical for both components.

Q: Should RoHS compliance status influence the selection?

A: Yes, if the application or end-market requires RoHS compliance. The substitute part (T520V477M2R5ATE015) is RoHS3 compliant, while the main part is RoHS non-compliant. Applications subject to RoHS regulations must use the substitute part.

Q: Is the substitute part available in higher inventory quantities?

A: Yes. The substitute part (T520V477M2R5ATE015) has 11,172 pieces in stock, compared to 938 pieces for the main part. The substitute part's active status and higher inventory support ongoing production requirements.
