Substitute Part Grouping Explanation

Substitution of the T520D107M010ASE080 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Capacitance: 100 µF (exact match required)
• Voltage Rating: 10 V (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Tolerance: ±20% (exact match required)
• Moisture Sensitivity Level: 3 (168 Hours) (exact match required)

Secondary Substitution Criteria:

• ESR @ 100 kHz: 80 mOhm (direct equivalents) or 55 mOhm (lower ESR alternative)
• Lifetime @ Temp.: 2000 Hrs @ 105°C (preferred but not mandatory for functional equivalence)
• RoHS Compliance: Preferred for new designs but not required for functional substitution

Substitute parts are grouped into three categories: direct manufacturer equivalents (same KEMET series with different packaging codes), parametric equivalents from alternative KEMET series, cross-manufacturer equivalents with identical electrical specifications, and similar parts with improved ESR performance.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Identical Electrical Performance):

The T520D107M010ATE080 is the primary direct replacement for the obsolete T520D107M010ASE080. Both parts are from the KEMET KO-CAP® T520 series with identical electrical specifications (100 µF, 10 V, 80 mOhm ESR). The T520D107M010ATE080 is active in production and ROHS3 compliant, making it suitable for new designs and ongoing procurement. The only difference is packaging format: the original part is supplied in bulk, while the substitute is supplied in Tape & Reel format.

Alternative KEMET Series (Same Electrical Performance):

The T520D107M010AHE080 and T591D107M010ATE080 provide equivalent electrical performance with identical capacitance, voltage, ESR, and package specifications. The T591D107M010ATE080 offers the advantage of ROHS3 compliance and active product status. Both parts are available in Tape & Reel packaging.

Cross-Manufacturer Equivalent (Identical Electrical Performance):

The TCJD107M010R0080E from KYOCERA AVX (TCJ series) matches all critical electrical parameters: 100 µF capacitance, 10 V rating, 80 mOhm ESR, and 2917 package. This part is active in production and ROHS3 compliant, providing a qualified alternative from a different manufacturer.

Lower ESR Alternative (Improved Performance):

The T55D107M010C0055 from Vishay Sprague (vPolyTan™ T55 series) provides superior ESR performance at 55 mOhm @ 100 kHz compared to the 80 mOhm specification of the original part. All other critical parameters remain identical: 100 µF, 10 V, 2917 package, and -55°C to 105°C operating range. This part is active and ROHS3 compliant. The lower ESR may provide improved performance in applications sensitive to impedance characteristics.

Compliance Considerations:

For applications requiring RoHS3 compliance, select T520D107M010ATE080, T591D107M010ATE080, TCJD107M010R0080E, or T55D107M010C0055. For applications with no compliance requirement, T520D107M010AHE080 remains available.

Frequently Asked Questions (FAQ)

Q: Can the T520D107M010ATE080 be used as a direct replacement for the obsolete T520D107M010ASE080?

A: Yes. Both parts are electrically identical with 100 µF capacitance, 10 V rating, 80 mOhm ESR @ 100 kHz, and 2917 package. The primary difference is packaging format: the original is supplied in bulk, while the substitute is supplied in Tape & Reel. Electrical performance and board-level compatibility are identical.

Q: What is the difference between the KEMET T520 and T591 series substitutes?

A: Both series provide identical electrical specifications for this part number (100 µF, 10 V, 80 mOhm ESR, 2917 package). The T591 series is a newer KEMET product line. Both are active in production and suitable for replacement applications.

Q: Why is the Vishay Sprague T55D107M010C0055 listed as a substitute if it has different ESR?

A: The T55D107M010C0055 is classified as a similar part rather than a direct equivalent due to its lower ESR specification (55 mOhm vs. 80 mOhm). However, it meets all other critical parameters: capacitance, voltage, package, and operating temperature. The lower ESR represents improved performance and is functionally compatible in applications where the original 80 mOhm ESR was acceptable.

Q: Are all substitute parts available in the same packaging format as the original?

A: No. The original T520D107M010ASE080 is supplied in bulk packaging. All listed substitutes are supplied in Tape & Reel (TR) format, which is standard for active production parts. Tape & Reel packaging is compatible with automated assembly equipment and is the industry standard for surface mount components.

Q: Which substitute part offers the best compliance profile?

A: Multiple parts offer ROHS3 compliance: T520D107M010ATE080, T591D107M010ATE080, TCJD107M010R0080E, and T55D107M010C0055. All are active in production. Selection should be based on availability, lead time, and specific design requirements beyond compliance.

Q: Can the KYOCERA AVX TCJD107M010R0080E be used interchangeably with KEMET parts?

A: Yes. The TCJD107M010R0080E provides identical electrical specifications (100 µF, 10 V, 80 mOhm ESR, 2917 package) and is functionally interchangeable at the board level. It is a qualified cross-manufacturer alternative from a different supplier, useful for supply chain diversification or availability purposes.

Q: What does MSL 3 (168 Hours) mean for these parts?

A: Moisture Sensitivity Level 3 indicates that the component can be exposed to moisture for a maximum of 168 hours before soldering. All listed parts share this specification, ensuring consistent handling and storage requirements across all substitutes.

Q: Is the operating temperature range identical across all substitute parts?

A: Yes. All substitute parts operate across the -55°C to 105°C temperature range, matching the original specification. This ensures thermal performance equivalence in all operating environments.
