Substitute Part Grouping Explanation

Substitution of the T520D337M006ASE040 is determined by strict equivalence across the following critical parameters: capacitance value (330 µF), voltage rating (6.3 V), tolerance (±20%), ESR specification (40 mOhm @ 100 kHz), package designation (2917 / 7343 Metric), mounting type (surface mount), operating temperature range (-55°C to 105°C), and lifetime rating (2000 Hrs @ 105°C). All substitute parts listed maintain these electrical and mechanical specifications without deviation.

Substitute parts are categorized into two groups:

KEMET KO-CAP® T520 and T522 Series (Direct Manufacturer Substitutes): Parts T520D337M006ATE040, T520V337M006ATE040, T522V337M006ATE040, and T520D337M006AHE040 are manufactured by KEMET and share the same base electrical specifications. Variations exist in packaging format (tape and reel versus bulk), product status (active versus obsolete), RoHS compliance status, and physical height dimensions. The T520V and T522V variants feature reduced seated heights of 1.90 mm compared to the 3.10 mm height of the original part, while T520D and T520D variants maintain the original 3.10 mm height.

KYOCERA AVX TCJ Series (Cross-Manufacturer Parametric Equivalents): Parts TCJY337M006R0040, TCJY337M006R0040E, TCJD337M006R0040, TCJD337M006R0040E, and TCJD337M006S0040 are manufactured by KYOCERA AVX and provide parametric equivalence across all critical electrical and mechanical specifications. These parts are active products with RoHS3 compliance. Height variations exist between TCJY variants (2.00 mm seated height) and TCJD variants (3.10 mm seated height).

Engineering Selection Recommendations

For designs requiring direct KEMET replacement with active product status and RoHS3 compliance: T520D337M006ATE040 is the primary selection. This part maintains identical electrical specifications, package dimensions, and 3.10 mm seated height as the original T520D337M006ASE040 while providing active product status and ROHS3 compliance.

For designs with height constraints permitting reduced profile: T520V337M006ATE040 and T522V337M006ATE040 both provide 1.90 mm seated heights, enabling integration into space-constrained applications. Both are active products with ROHS3 compliance. The distinction between T520V and T522V series does not affect electrical or mechanical compatibility for this specification.

For designs requiring non-compliant RoHS status matching the original part: T520D337M006AHE040 maintains the original RoHS non-compliant status while providing active product availability and identical electrical specifications.

For cross-manufacturer substitution with KYOCERA AVX: TCJD337M006R0040, TCJD337M006R0040E, and TCJD337M006S0040 provide parametric equivalence with 3.10 mm seated heights and active product status with ROHS3 compliance. TCJY337M006R0040 and TCJY337M006R0040E offer reduced 2.00 mm seated heights with identical electrical specifications and active status with ROHS3 compliance.

All substitute parts maintain the 2917 (7343 Metric) package footprint, surface mount mounting type, -55°C to 105°C operating temperature range, 2000-hour lifetime at 105°C, and Moisture Sensitivity Level 3 (168 Hours) specification.

Frequently Asked Questions (FAQ)

Q: Can T520D337M006ATE040 be used as a direct replacement for T520D337M006ASE040?

A: Yes. T520D337M006ATE040 maintains identical electrical specifications (330 µF, 6.3 V, 40 mOhm ESR @ 100 kHz), package designation (2917), and physical dimensions (3.10 mm seated height). The primary differences are product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant). Electrical and mechanical compatibility is complete.

Q: What is the difference between T520V337M006ATE040 and T520D337M006ATE040?

A: Both parts share identical electrical specifications and package footprint. The distinction is physical height: T520V provides 1.90 mm seated height while T520D provides 3.10 mm seated height. Selection depends on available board space. Electrical performance and thermal characteristics are equivalent.

Q: Are KYOCERA AVX TCJ series parts compatible with KEMET KO-CAP® T520 designs?

A: Yes. TCJD337M006R0040, TCJD337M006R0040E, and TCJD337M006S0040 provide parametric equivalence across all critical electrical and mechanical specifications: 330 µF capacitance, 6.3 V voltage rating, 40 mOhm ESR @ 100 kHz, 2917 package, and 3.10 mm seated height. Cross-manufacturer substitution is electrically and mechanically valid.

Q: What is the significance of the "E" suffix in TCJY337M006R0040E and TCJD337M006R0040E?

A: The "E" suffix denotes a variant designation within the KYOCERA AVX TCJ series. Electrical specifications, package dimensions, and performance characteristics remain identical to parts without the "E" suffix. The suffix does not affect substitution compatibility.

Q: Can parts with 1.90 mm height (T520V, TCJY) be used in designs originally specified for 3.10 mm height (T520D, TCJD)?

A: Yes, from an electrical and footprint perspective. The reduced height provides additional clearance and may improve thermal performance in space-constrained layouts. However, board layout and component placement must accommodate the lower profile. Mechanical clearance verification is required.

Q: Are all substitute parts RoHS3 compliant?

A: No. T520D337M006AHE040 maintains RoHS non-compliant status matching the original part. All KEMET T520D and T520V active variants (T520D337M006ATE040, T520V337M006ATE040) and all KEMET T522V variants (T522V337M006ATE040) are ROHS3 compliant. All KYOCERA AVX TCJ variants listed are ROHS3 compliant. RoHS compliance selection depends on regulatory and procurement requirements.

Q: What is the inventory status of substitute parts?

A: T520D337M006ATE040 (2,388 units), T520V337M006ATE040 (1,400 units), T522V337M006ATE040 (2,927 units), T520D337M006AHE040 (1,050 units), TCJY337M006R0040 (4,913 units), TCJY337M006R0040E (6,206 units), TCJD337M006R0040 (2,280 units), TCJD337M006R0040E (2,361 units), and TCJD337M006S0040 (757 units) are available as new original stock. Inventory levels support production requirements across all substitute options.

Q: Do all substitute parts maintain the same operating temperature range and lifetime rating?

A: Yes. All substitute parts operate across -55°C to 105°C and maintain a 2000-hour lifetime rating at 105°C. Thermal performance and reliability characteristics are equivalent across all listed substitutes.
