Key Parameters

Substitute Part Grouping Explanation

Substitution of the T520V477M002ASE040 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 470 µF (exact match required)
• Voltage Rating: 2 V (exact match required)
• ESR Specification: 40 mOhm @ 100 kHz (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Tolerance: ±20% (exact match required)
• Lifetime @ Temperature: 2000 Hrs @ 105°C (exact match required)
• Moisture Sensitivity Level: 3 (168 Hours) (exact match required)

Substitute parts must maintain identical electrical and mechanical specifications to ensure functional compatibility within existing circuit designs and PCB layouts. Packaging format differences (such as tape and reel versus alternative packaging) do not affect electrical or mechanical performance and are therefore permissible variations.

Parameter Comparison

Engineering Selection Recommendations

The T520V477M002ATE040 is the direct substitute for the obsolete T520V477M002ASE040. Both components are manufactured by KEMET within the KO-CAP® T520 series and share identical electrical and mechanical specifications across all critical parameters including capacitance, voltage rating, ESR, package dimensions, and operating characteristics.

The primary distinction between these parts is product status and regulatory compliance. The T520V477M002ASE040 is classified as obsolete and carries RoHS non-compliant status. The T520V477M002ATE040 maintains active product status and achieves ROHS3 compliance, making it the appropriate selection for new designs and ongoing production where regulatory requirements must be satisfied.

Both parts are available in surface mount configuration with identical 2917 (7343 Metric) package geometry, ensuring direct PCB compatibility. The T520V477M002ATE040 is supplied in tape and reel packaging format, which is standard for high-volume manufacturing operations and does not affect electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the T520V477M002ATE040 be used as a direct replacement for the T520V477M002ASE040?

A: Yes. The T520V477M002ATE040 is electrically and mechanically equivalent to the T520V477M002ASE040. All critical parameters including capacitance (470 µF), voltage rating (2 V), ESR (40 mOhm @ 100 kHz), package dimensions (2917 / 7343 Metric), and operating temperature range (-55°C ~ 105°C) are identical. The substitute part is suitable for direct PCB placement without design modification.

Q: What is the difference between the T520V477M002ASE040 and T520V477M002ATE040?

A: The primary differences are product status and regulatory compliance. The T520V477M002ASE040 is obsolete and RoHS non-compliant. The T520V477M002ATE040 is active and ROHS3 compliant. Additionally, the T520V477M002ATE040 is supplied in tape and reel packaging, whereas the main part uses standard packaging. Electrical and mechanical specifications are identical.

Q: Does the tape and reel packaging of the T520V477M002ATE040 affect its performance?

A: No. Packaging format is a supply chain and manufacturing consideration only. Tape and reel packaging does not alter the electrical characteristics, mechanical dimensions, or performance of the capacitor. The component itself remains identical.

Q: Are there any compliance or regulatory considerations when substituting these parts?

A: Yes. The T520V477M002ASE040 is RoHS non-compliant, while the T520V477M002ATE040 is ROHS3 compliant. If your application or market requires RoHS compliance, the T520V477M002ATE040 is the appropriate selection. Both parts maintain REACH Unaffected status and EAR99 export classification.

Q: Will the T520V477M002ATE040 fit the same PCB footprint as the T520V477M002ASE040?

A: Yes. Both components use the identical 2917 (7343 Metric) package with matching dimensions of 0.287" L x 0.169" W (7.30mm x 4.30mm) and maximum seated height of 0.075" (1.90mm). PCB footprints and assembly processes require no modification.

Q: What is the moisture sensitivity level for these capacitors?

A: Both the T520V477M002ASE040 and T520V477M002ATE040 carry MSL 3 rating with a 168-hour floor life. Standard moisture control procedures during storage, handling, and assembly are required to maintain component reliability.
