Engineering Selection Recommendations

Primary Substitute: T520V337M006ATE040

The T520V337M006ATE040 is the direct equivalent of the obsolete T520V337M006ASE040. Both parts belong to the KO-CAP® T520 series and maintain identical electrical and mechanical specifications. The T520V337M006ATE040 is classified as active product status and is ROHS3 compliant, making it the preferred choice for new designs and production applications requiring regulatory compliance.

Alternative Substitutes: T520V337M006AHE0407706 and T522V337M006ATE040

The T520V337M006AHE0407706 and T522V337M006ATE040 are parametric equivalents that satisfy all critical electrical and mechanical requirements. The T522V337M006ATE040 belongs to the KO-CAP® T522 series but maintains identical performance characteristics. Both parts are active and ROHS3 compliant. Selection between these alternatives depends on inventory availability and procurement lead times, as all three substitute parts are functionally interchangeable within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the T520V337M006ATE040 be used as a direct replacement for the obsolete T520V337M006ASE040?

A: Yes. The T520V337M006ATE040 is a direct equivalent with identical capacitance (330 µF), voltage rating (6.3 V), ESR (40 mOhm @ 100 kHz), package (2917/7343 Metric), and operating temperature range (-55°C ~ 105°C). The primary difference is product status (active vs. obsolete) and packaging format (Tape & Reel vs. bulk).

Q: What is the difference between the T520 and T522 series parts?

A: Both the T520V337M006ATE040 and T522V337M006ATE040 meet all specified electrical and mechanical parameters for substitution. The difference lies in the series designation; however, both deliver identical performance in the 330 µF, 6.3 V, 40 mOhm configuration within the 2917 package.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (T520V337M006ATE040, T520V337M006AHE0407706, and T522V337M006ATE040) are ROHS3 compliant. The original part T520V337M006ASE040 is RoHS non-compliant.

Q: Does packaging format affect electrical performance?

A: No. The Tape & Reel (TR) packaging of substitute parts does not affect electrical performance. Packaging format impacts handling, storage, and automated assembly processes only.

Q: Are the physical dimensions identical across all parts?

A: Yes. All parts share identical dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm) with a maximum seated height of 0.075" (1.90mm).

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts, including the main part and substitutes, have an MSL rating of 3 with a floor life of 168 hours.
