T520D337M004ASE015 Equivalent & Substitute Parts

Part Overview

The T520D337M004ASE015 is a 330 µF molded tantalum polymer capacitor rated for 4 V operation in a 2917 (7343 Metric) surface mount package. This component is manufactured by KEMET under the KO-CAP® T520 series and is classified as obsolete. The part features 15 mOhm equivalent series resistance at 100 kHz and operates across a temperature range of -55°C to 105°C with a 2000-hour lifetime rating at 105°C.

Due to the obsolete product status of the T520D337M004ASE015, identifying equivalent and substitute parts is necessary to maintain design continuity and ensure component availability for production and repair applications. Substitute parts must maintain identical electrical characteristics and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the T520D337M004ASE015 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 330 µF (±20% tolerance)
• Voltage rating: 4 V minimum
• ESR: 15 mOhm @ 100 kHz
• Operating temperature range: -55°C to 105°C minimum
• Lifetime specification: 2000 Hrs @ 105°C

Mechanical Parameters:

• Package type: 2917 (7343 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 0.287" L × 0.169" W (7.30 mm × 4.30 mm)
• Maximum seated height: 0.122" (3.10 mm)

Compliance Parameters:

• Moisture Sensitivity Level: 3 (168 Hours)
• REACH Status: REACH Unaffected
• ECCN: EAR99

Substitute parts must match all electrical and mechanical parameters without deviation. Packaging format (Tape & Reel versus bulk) does not affect electrical or mechanical compatibility and is considered a secondary selection criterion.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: T520D337M004ATE015 (KEMET)

The T520D337M004ATE015 is the direct manufacturer equivalent from KEMET. This part maintains complete electrical and mechanical parity with the obsolete T520D337M004ASE015 while offering active product status. The primary distinction is packaging format (Tape & Reel versus bulk) and improved RoHS3 compliance. This part is the preferred substitute when KEMET component continuity is required.

Secondary Substitute: TCJD337M004R0015 (KYOCERA AVX)

The TCJD337M004R0015 provides parametric equivalence across all critical electrical and mechanical specifications. This cross-manufacturer substitute is suitable when KEMET availability is constrained or when multi-source component qualification is required. The KYOCERA AVX TCJ series offers active product status and ROHS3 compliance. Selection of this part requires confirmation that the design does not impose manufacturer-specific requirements.

Compliance Considerations:

Both substitute parts achieve ROHS3 compliance, whereas the original T520D337M004ASE015 is RoHS non-compliant. Applications subject to RoHS regulatory requirements must transition to either substitute part. Both substitutes maintain REACH Unaffected status and EAR99 export classification consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the T520D337M004ATE015 be used as a direct replacement for the T520D337M004ASE015?

A: Yes. The T520D337M004ATE015 is electrically and mechanically identical to the T520D337M004ASE015. The primary difference is packaging format (Tape & Reel) and active product status. Both parts share identical capacitance, voltage rating, ESR, package dimensions, and operating specifications.

Q: What is the difference between the two KEMET part numbers?

A: The T520D337M004ASE015 and T520D337M004ATE015 differ only in packaging delivery format. The "SE" suffix indicates standard packaging, while the "TE" suffix indicates Tape & Reel packaging. Electrical and mechanical specifications are identical. The T520D337M004ATE015 is the active production equivalent.

Q: Is the TCJD337M004R0015 from KYOCERA AVX fully compatible?

A: The TCJD337M004R0015 meets all electrical and mechanical substitution criteria. Capacitance, voltage rating, ESR, package type, dimensions, and operating temperature range are identical. The part is suitable for applications without manufacturer-specific design constraints.

Q: Does switching to a substitute part require PCB layout changes?

A: No. All substitute parts use the identical 2917 (7343 Metric) package with matching footprint dimensions (0.287" L × 0.169" W, 7.30 mm × 4.30 mm) and maximum seated height (0.122" / 3.10 mm). PCB layout and assembly processes remain unchanged.

Q: Are there any compliance differences between the original and substitute parts?

A: The original T520D337M004ASE015 is RoHS non-compliant. Both substitute parts (T520D337M004ATE015 and TCJD337M004R0015) are ROHS3 compliant. All three parts maintain REACH Unaffected status and EAR99 export classification. Applications subject to RoHS requirements must use one of the compliant substitutes.

Q: What is the moisture sensitivity level, and does it affect handling?

A: All three parts carry Moisture Sensitivity Level 3 (168 Hours). This classification requires controlled storage and handling procedures. Components must be stored in dry conditions and baked according to IPC standards before reflow soldering if exposed to moisture.

Q: Can inventory of the obsolete T520D337M004ASE015 be used interchangeably with the active substitutes?

A: Yes. The T520D337M004ASE015 and T520D337M004ATE015 are electrically and mechanically interchangeable. Existing inventory of the obsolete part can be used in applications without modification. However, for new production, the active T520D337M004ATE015 is recommended to ensure long-term supply continuity.
