Substitute Part Grouping Explanation

Substitution eligibility for the T520V337M2R5ASE015 is determined by strict equivalence across the following parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 2.5 V (exact match required)
• ESR @ 100 kHz: 15 mOhm (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• Lifetime @ 105°C: 2000 Hours (exact match required)
• Type: Molded Tantalum Polymer (exact match required)
• Tolerance: ±20% (exact match required)
• MSL Rating: 3 (168 Hours) (exact match required)

All substitute parts listed below meet these criteria. Substitutes are grouped into two categories: Direct Manufacturer Substitutes (packaging variants) and Parametric Equivalents (internal construction variants with identical electrical and mechanical specifications).

Engineering Selection Recommendations

Primary Recommendation: T520V337M2R5ATE015

The T520V337M2R5ATE015 is the direct functional equivalent of the obsolete T520V337M2R5ASE015. Both parts share identical electrical specifications (330 µF, 2.5 V, 15 mOhm ESR) and mechanical dimensions (2917 package, 1.90 mm height). The primary difference is product status and compliance: T520V337M2R5ATE015 is active and RoHS3 compliant, whereas the original part is obsolete and RoHS non-compliant. This part is supplied in Tape & Reel packaging, standard for production environments.

Secondary Recommendation: T520W337M2R5ATE015

The T520W337M2R5ATE015 maintains all electrical parameters identical to the original part but features a reduced seated height of 1.50 mm (versus 1.90 mm). This variant is suitable for applications with space constraints or height-limited PCB designs. The part is active and RoHS3 compliant.

Parametric Equivalents: T520V337M2R5ATE0152478, T520V337M2R5ATE0154539, T520V337M2R5ATE0157333, T520V337M2R5ATE0157627

These four part numbers represent internal construction variants within the KEMET KO-CAP® T520 series. All four maintain identical electrical and mechanical specifications to the original part, including 330 µF capacitance, 2.5 V rating, 15 mOhm ESR, and 1.90 mm maximum height. These parts are active and RoHS3 compliant. Selection among these variants is based on inventory availability and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can T520V337M2R5ATE015 be used as a direct replacement for T520V337M2R5ASE015?

A: Yes. Both parts are electrically and mechanically identical. The T520V337M2R5ATE015 is the active production equivalent with improved compliance status (RoHS3 compliant versus RoHS non-compliant). The only difference is packaging format: the original uses bulk packaging while the substitute uses Tape & Reel.

Q: What is the difference between T520V337M2R5ATE015 and T520W337M2R5ATE015?

A: Both parts have identical electrical specifications (330 µF, 2.5 V, 15 mOhm ESR). The difference is seated height: T520V337M2R5ATE015 has a maximum height of 1.90 mm, while T520W337M2R5ATE015 has a maximum height of 1.50 mm. The W-variant is suitable for height-constrained applications.

Q: Are the parametric equivalent part numbers (ending in 2478, 4539, 7333, 7627) interchangeable?

A: Yes. These four part numbers represent different manufacturing batches or internal construction variants within the same electrical and mechanical specification envelope. All four are parametrically equivalent to the original part and to each other.

Q: What does RoHS3 compliance mean for this capacitor?

A: RoHS3 compliance indicates the part meets the Restriction of Hazardous Substances Directive requirements. The original T520V337M2R5ASE015 is RoHS non-compliant. All active substitute parts are RoHS3 compliant, making them suitable for applications requiring regulatory compliance.

Q: Can I use these substitutes in existing designs without PCB modification?

A: Yes, for T520V337M2R5ATE015 and the parametric equivalents. These maintain the identical 2917 package footprint and 1.90 mm height as the original. The T520W337M2R5ATE015 also uses the same footprint but with reduced height (1.50 mm), which is compatible with existing designs but offers additional clearance.

Q: What is MSL 3 (168 Hours) and why does it matter?

A: MSL (Moisture Sensitivity Level) 3 indicates the component requires controlled storage conditions. The 168-hour specification means the part can be exposed to ambient conditions (30°C, 60% RH) for up to 168 hours before soldering. All listed substitutes maintain this same MSL rating.
