Substitute Part Grouping Explanation

Substitution eligibility for the T520D337M004ASE009 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 330 µF
• Voltage Rating: 4 V
• ESR: 9 mOhm @ 100 kHz
• Package / Case: 2917 (7343 Metric)
• Type: Molded Tantalum Polymer
• Operating Temperature Range: -55°C to 105°C
• Lifetime @ 105°C: 2000 Hours
• Tolerance: ±20%
• MSL Rating: 3 (168 Hours)

Variable Parameters (Allowed Differences):

• Packaging format (Tape & Reel vs. other formats)
• Height - Seated (Max) dimension
• Manufacturer Size Code designation
• Product Status (Active vs. Obsolete)
• RoHS compliance level

The substitute parts T520D337M004ATE009 and T520V337M004ATE009 maintain all mandatory electrical and thermal specifications while differing in packaging configuration and physical height dimensions.

Parameter Comparison

Engineering Selection Recommendations

T520D337M004ATE009 is the primary substitute for the obsolete T520D337M004ASE009. Both parts share identical electrical specifications, thermal ratings, and mechanical dimensions. The T520D337M004ATE009 maintains active product status and achieves ROHS3 compliance, providing improved regulatory alignment for new designs and ongoing production. The packaging format difference (Tape & Reel) supports automated assembly processes and is standard for active production components.

T520V337M004ATE009 is a secondary substitute option with identical electrical and thermal performance. This part differs in physical height (0.075" vs. 0.122"), designated by the "V" size code. Selection of this variant is appropriate only when PCB layout constraints or clearance requirements necessitate the reduced height profile. All other functional and compliance characteristics remain equivalent to the primary substitute.

Both substitute parts are manufactured by KEMET within the same KO-CAP® T520 series and carry ROHS3 compliance certification, supporting modern supply chain and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can T520D337M004ATE009 directly replace T520D337M004ASE009 in existing designs?

A: Yes. Both parts are electrically and thermally identical with matching capacitance (330 µF), voltage rating (4 V), ESR (9 mOhm @ 100 kHz), and package dimensions (2917 / 7343 Metric). The primary difference is packaging format (Tape & Reel vs. standard) and product status (Active vs. Obsolete). PCB layout and assembly compatibility are maintained.

Q: What is the significance of the "D" and "V" size codes in the part numbers?

A: The size code designates the physical height of the molded component. "D" indicates a maximum seated height of 0.122" (3.10mm), while "V" indicates 0.075" (1.90mm). Both maintain identical footprint dimensions (0.287" L x 0.169" W). Selection depends on available PCB clearance and assembly requirements.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both T520D337M004ATE009 and T520V337M004ATE009 are ROHS3 compliant. The original T520D337M004ASE009 is RoHS non-compliant. This compliance upgrade supports modern regulatory requirements and supply chain standards.

Q: What is the difference between Tape & Reel packaging and standard packaging?

A: Tape & Reel (TR) packaging is configured for automated pick-and-place assembly equipment, providing components on continuous carrier tape with sprocket holes. Standard packaging typically refers to bulk or alternative formats. For high-volume production, Tape & Reel is the industry standard and offers cost and efficiency advantages.

Q: Can T520V337M004ATE009 be used in applications with tight vertical clearance?

A: Yes. The reduced height of 0.075" (1.90mm) compared to 0.122" (3.10mm) makes T520V337M004ATE009 suitable for space-constrained designs. All electrical specifications remain identical, ensuring functional equivalence in applications where height is a limiting factor.

Q: Are there any thermal or lifetime differences between the substitute parts?

A: No. All three parts share identical operating temperature range (-55°C to 105°C) and lifetime rating (2000 Hours @ 105°C). Thermal performance and reliability characteristics are equivalent across all variants.
