  • ESR Specification: 45 mOhm @ 100 kHz (exact match required)
  • Package / Case: 2917 (7343 Metric) (exact match required)
  • Operating Temperature Range: -55°C to 105°C (exact match required)
  • Lifetime Rating: 2000 Hours @ 105°C (exact match required)
  • Mounting Type: Surface Mount (exact match required)
  • Tolerance: ±20% (exact match required)
  • MSL Rating: 3 (168 Hours) (exact match required)

Engineering Selection Recommendations

T520D337M006ATE045 is the primary direct substitute for the obsolete T520D337M006ASE045. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The transition from bulk packaging to Tape & Reel format aligns with current manufacturing and assembly standards.

T520V337M006ATE045 provides parametric equivalence with all critical electrical specifications matching the main part. The distinction lies in the manufacturer size code (V versus D), resulting in a reduced seated height of 0.075" (1.90mm) compared to 0.122" (3.10mm). This part is suitable for applications where vertical clearance constraints exist within the 2917 package footprint. ROHS3 compliance and active product status apply.

T520D337M006ATE0457280 offers parametric equivalence with identical seated height and all electrical specifications matching the main part. This variant includes extended packaging designation and maintains ROHS3 compliance and active product status.

All three substitute parts are manufactured by KEMET within the KO-CAP® T520 series and are classified as active products with current availability. Selection between T520D337M006ATE045 and T520D337M006ATE0457280 depends on packaging and supply chain requirements, as both maintain identical physical and electrical characteristics. T520V337M006ATE045 is selected only when reduced component height is a design requirement.

Frequently Asked Questions (FAQ)

Q: Can T520D337M006ATE045 be used as a direct replacement for T520D337M006ASE045?

A: Yes. T520D337M006ATE045 maintains identical electrical and mechanical specifications including capacitance (330 µF), voltage rating (6.3 V), ESR (45 mOhm @ 100 kHz), package (2917), operating temperature range (-55°C to 105°C), and lifetime rating (2000 Hrs @ 105°C). The primary differences are product status (Active versus Obsolete), RoHS compliance (ROHS3 versus Non-Compliant), and packaging format (Tape & Reel versus Bulk).

Q: What is the difference between T520D337M006ATE045 and T520D337M006ATE0457280?

A: Both parts are electrically and mechanically identical. The difference is in the packaging designation suffix. Both maintain the same seated height of 0.122" (3.10mm), electrical specifications, and active product status with ROHS3 compliance. Selection between these two is based on supply chain availability and packaging requirements.

Q: When should T520V337M006ATE045 be selected instead of T520D337M006ATE045?

A: T520V337M006ATE045 is selected when vertical space constraints require a reduced component height. This part has a seated height of 0.075" (1.90mm) compared to 0.122" (3.10mm) for the D-variant. All other electrical and mechanical specifications remain identical. The V designation indicates the manufacturer size code difference.

Q: Are all substitute parts RoHS compliant?

A: All three substitute parts (T520D337M006ATE045, T520V337M006ATE045, and T520D337M006ATE0457280) are ROHS3 compliant. The original part T520D337M006ASE045 is RoHS non-compliant. This compliance upgrade is a key advantage of transitioning to active production alternatives.

Q: What is the MSL rating and why is it important?

A: All parts including the main component and substitutes carry an MSL (Moisture Sensitivity Level) rating of 3 with a 168-hour floor life. This indicates the component requires controlled storage conditions and has a specified time window for assembly after exposure to moisture. Proper handling according to MSL 3 requirements is necessary for all listed parts.

Q: Are there any differences in operating temperature or lifetime specifications?

A: No. All parts maintain identical operating temperature range (-55°C to 105°C) and lifetime rating (2000 Hours @ 105°C). These critical reliability parameters are consistent across the main part and all substitutes.

Q: What packaging formats are available?

A: The original T520D337M006ASE045 is supplied in bulk packaging. All substitute parts (T520D337M006ATE045, T520V337M006ATE045, and T520D337M006ATE0457280) are supplied in Tape & Reel (TR) format, which is the current standard for surface mount component distribution and automated assembly.
