Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the T520V337M003ASE025 are categorized based on the following substitution criteria:

Direct Equivalent (Packaging Variant): Parts maintaining identical electrical specifications (330 µF, 3 V, 25 mOhm ESR) but differing in packaging format (Tape & Reel versus Cut Tape).

Upgrade Substitutes (Voltage Rating Increase): Parts with identical capacitance (330 µF) and ESR (25 mOhm @ 100 kHz) but higher voltage ratings (4 V or 6.3 V). These provide enhanced voltage margin and are electrically compatible in applications operating below the original 3 V specification.

Similar Substitutes (ESR Reduction): Parts with identical capacitance (330 µF) and voltage rating (3 V) but lower ESR (15 mOhm @ 100 kHz), offering improved performance characteristics while maintaining the same electrical operating point.

All substitute parts share the same series designation (KO-CAP® T520), package footprint (2917 / 7343 Metric), temperature range (-55°C ~ 105°C), and compliance certifications (ROHS3, REACH Unaffected).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: T520V337M003ATE025 is the direct functional equivalent with active product status. This part maintains all electrical specifications of the obsolete T520V337M003ASE025 while offering superior supply chain availability (2198 units in stock). The transition from standard packaging to Tape & Reel format aligns with modern manufacturing practices.

Secondary Recommendation for Voltage Margin: T520V337M004ATE025 and T520V337M006ATE025 are suitable for applications where circuit design permits higher voltage ratings. These upgrades provide additional voltage headroom and maintain identical capacitance and ESR characteristics. T520V337M006ATE025 offers the highest inventory level (18850 units), supporting long-term supply security.

Performance Enhancement Option: T520V337M003ATE015 provides identical voltage and capacitance specifications with reduced ESR (15 mOhm versus 25 mOhm). This substitution improves frequency response and thermal performance in applications sensitive to impedance characteristics.

All recommended substitutes maintain ROHS3 compliance, REACH unaffected status, and identical operating temperature ranges (-55°C ~ 105°C) and moisture sensitivity levels (MSL 3).

Frequently Asked Questions (FAQ)

Q: Can T520V337M003ATE025 directly replace T520V337M003ASE025?

A: Yes. Both parts share identical electrical specifications: 330 µF capacitance, 3 V voltage rating, and 25 mOhm ESR @ 100 kHz. The primary difference is packaging format (Tape & Reel versus standard). Footprint and mounting characteristics are identical for the 2917 (7343 Metric) package.

Q: What is the difference between the upgrade parts (4 V and 6.3 V versions)?

A: Upgrade parts maintain the same capacitance (330 µF) and ESR (25 mOhm @ 100 kHz) but feature higher voltage ratings. These are electrically compatible in circuits operating at 3 V or below, providing additional voltage safety margin. Selection depends on circuit voltage requirements and design margins.

Q: How does T520V337M003ATE015 differ from the main part?

A: T520V337M003ATE015 maintains identical capacitance (330 µF) and voltage rating (3 V) but features lower ESR (15 mOhm versus 25 mOhm @ 100 kHz). This reduction in equivalent series resistance improves high-frequency performance and reduces thermal dissipation. Selection depends on application frequency response requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original T520V337M003ASE025 specifications.

Q: What packaging formats are available?

A: T520V337M003ATE025 and T520V337M004ATE025 are supplied in Tape & Reel (TR) format. T520V337M006ATE025 is available in Cut Tape (CT) & Digi-Reel® format. T520V337M003ATE015 is supplied in Tape & Reel (TR) format. Selection depends on assembly equipment compatibility and procurement requirements.

Q: Which substitute offers the best supply availability?

A: T520V337M006ATE025 provides the highest inventory level at 18850 units in stock, supporting extended production runs and supply chain continuity.
