Substitute Part Grouping Explanation

Substitute parts for the T520V337M003ASE015 are identified based on strict electrical and mechanical parameter matching within the KEMET KO-CAP® T520 series. The substitution logic is based on the following critical parameters:

Electrical Parameters (Must Match):

• Capacitance: 330 µF
• Voltage Rating: 3 V
• ESR: 15 mOhm @ 100 kHz
• Operating Temperature Range: -55°C ~ 105°C
• Lifetime @ Temp.: 2000 Hrs @ 105°C
• Tolerance: ±20%

Mechanical Parameters (Must Match):

• Package / Case: 2917 (7343 Metric)
• Mounting Type: Surface Mount
• Size / Dimension: 0.287" L x 0.169" W (7.30 mm x 4.30 mm)
• Height - Seated (Max): 0.075" (1.90 mm)
• Moisture Sensitivity Level: 3 (168 Hours)

Allowed Variations:

• Packaging format (Bulk vs. Tape & Reel)
• Product status (Obsolete to Active)
• RoHS compliance status

Parameter Comparison

Engineering Selection Recommendations

T520V337M003ATE015 is the primary direct substitute for the obsolete T520V337M003ASE015. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The primary difference is packaging format (Tape & Reel vs. Bulk), which does not affect electrical performance or board-level compatibility. This part is recommended for new designs and ongoing production where RoHS compliance is required.

T520V337M003ATE015E012 is a parametric equivalent offering identical electrical and mechanical specifications with active product status and ROHS3 compliance. This part is suitable for applications where the specific packaging variant designated by the E012 suffix is required. Selection between T520V337M003ATE015 and T520V337M003ATE015E012 should be based on packaging requirements and supply chain availability.

For applications where RoHS non-compliance is not a constraint and bulk packaging is preferred, the original T520V337M003ASE015 remains available with 995 pieces in stock. However, transition to active, RoHS-compliant alternatives is recommended for long-term supply security.

Frequently Asked Questions (FAQ)

Q: Can T520V337M003ATE015 be used as a direct replacement for T520V337M003ASE015 on existing PCBs?

A: Yes. Both parts share identical electrical specifications (330 µF, 3 V, 15 mOhm ESR), mechanical dimensions (2917 package, 7.30 mm x 4.30 mm x 1.90 mm max height), and surface mount compatibility. The packaging format difference (Tape & Reel vs. Bulk) does not affect board-level performance or placement.

Q: What is the difference between T520V337M003ATE015 and T520V337M003ATE015E012?

A: Both parts are electrically and mechanically identical. The E012 suffix designates a specific packaging variant. Selection should be based on procurement and assembly requirements. Consult KEMET documentation for packaging variant specifications.

Q: Why is the original T520V337M003ASE015 marked as obsolete?

A: Product obsolescence is determined by the manufacturer based on production lifecycle decisions. Active alternatives with identical specifications are available through T520V337M003ATE015 and T520V337M003ATE015E012.

Q: Are there RoHS compliance differences between these parts?

A: Yes. T520V337M003ASE015 is RoHS non-compliant. T520V337M003ATE015 and T520V337M003ATE015E012 are both ROHS3 compliant. For applications subject to RoHS regulations, use the compliant alternatives.

Q: Will substituting these parts require PCB layout changes?

A: No. All three parts use the 2917 (7343 Metric) package with identical footprint dimensions and surface mount compatibility. No PCB redesign is necessary.

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

A: All three parts have MSL 3 (168 Hours). This indicates standard moisture sensitivity requiring controlled storage and handling per IPC-A-610 guidelines. Bake-out procedures may be required if parts exceed moisture exposure limits.

Q: Is inventory availability a factor in part selection?

A: Current inventory shows T520V337M003ATE015 with 3300 pieces available, compared to 1116 pieces for T520V337M003ATE015E012 and 995 pieces for the obsolete T520V337M003ASE015. For high-volume production, T520V337M003ATE015 offers superior supply availability.
