Substitute Part Grouping Explanation

Substitution of the T520V477M2R5ASE012 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Capacitance value: 470 µF (exact match required)
• Voltage rating: 2.5 V (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• ESR @ 100 kHz: 12 mOhm (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C to 105°C (exact match required)

The direct substitute T520V477M2R5ATE012 maintains identical electrical and mechanical specifications while differing only in packaging format (Tape & Reel versus standard packaging) and product status (Active versus Obsolete). This part is the primary equivalent for direct replacement applications.

Packaging Format: The T520V477M2R5ASE012 is supplied in standard packaging, while the T520V477M2R5ATE012 is supplied in Tape & Reel (TR) format. Packaging selection depends on assembly process requirements and volume considerations.

Electrical and Mechanical Equivalence: Both parts are electrically and mechanically identical across all specified parameters, including capacitance, voltage rating, ESR, package dimensions, and operating temperature range. Direct substitution is permissible without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the T520V477M2R5ATE012 be used as a direct replacement for the T520V477M2R5ASE012?

A: Yes. The T520V477M2R5ATE012 is electrically and mechanically equivalent to the T520V477M2R5ASE012. Both parts share identical capacitance (470 µF), voltage rating (2.5 V), ESR (12 mOhm @ 100 kHz), package dimensions (2917 / 7343 Metric), and operating temperature range (-55°C to 105°C). Direct substitution is permissible without circuit modification.

Q: What is the primary difference between these two parts?

A: The primary differences are product status and packaging format. The T520V477M2R5ASE012 is Obsolete and supplied in standard packaging. The T520V477M2R5ATE012 is Active and supplied in Tape & Reel (TR) format. Additionally, the T520V477M2R5ATE012 is ROHS3 Compliant, while the T520V477M2R5ASE012 is RoHS non-compliant.

Q: Are there any physical dimension differences between these parts?

A: No. Both parts are housed in the 2917 (7343 Metric) package with identical dimensions: 0.287" L x 0.169" W (7.30mm x 4.30mm) and a maximum seated height of 0.075" (1.90mm). PCB footprints and assembly processes are identical.

Q: Which part should be selected for new designs?

A: The T520V477M2R5ATE012 is recommended for new designs. This part carries Active product status, ensuring long-term availability and manufacturer support. Additionally, ROHS3 compliance aligns with current regulatory requirements and customer specifications.

Q: Does the Tape & Reel packaging affect electrical performance?

A: No. Packaging format (standard versus Tape & Reel) does not affect electrical performance or component specifications. The selection between packaging formats is determined by assembly process requirements, volume considerations, and handling procedures.

Q: What is the MSL rating, and does it differ between these parts?

A: Both parts carry an MSL (Moisture Sensitivity Level) rating of 3 with a floor life of 168 hours. This rating is identical for both components and indicates the same moisture handling and storage requirements.
