Substitute Part Grouping Explanation

Substitution of the T520B336M008ASE040 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Capacitance: 33 µF (exact match required)
• Voltage Rating: 8 V (exact match required)
• Package / Case: 1411 (3528 Metric) (exact match required)
• ESR: 40 mOhm @ 100 kHz (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)

The T520B336M008ATE040 qualifies as a direct substitute. This part maintains identical electrical specifications and mechanical dimensions while differing only in packaging format (Tape & Reel versus bulk packaging) and product status (Active versus Obsolete). The substitution is valid for applications requiring the specified capacitance, voltage, and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The T520B336M008ATE040 is the appropriate substitute for the obsolete T520B336M008ASE040. Both parts maintain identical electrical and mechanical specifications across all critical parameters including capacitance, voltage rating, ESR, package dimensions, and operating temperature range.

The T520B336M008ATE040 carries an Active product status, ensuring continued availability and supply chain support. This part is ROHS3 compliant, providing regulatory advantage over the non-compliant main part. The difference in packaging format (Tape & Reel versus bulk) does not affect electrical performance or mechanical compatibility in surface mount applications.

Selection of the T520B336M008ATE040 is based on functional equivalence, product availability, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can the T520B336M008ATE040 be used as a direct replacement for the T520B336M008ASE040?

A: Yes. Both parts are electrically and mechanically identical. They share the same capacitance (33 µF), voltage rating (8 V), ESR (40 mOhm @ 100 kHz), package dimensions (1411 / 3528 Metric), and operating temperature range (-55°C ~ 105°C). The only differences are product status and packaging format.

Q: What is the difference between the packaging formats?

A: The T520B336M008ASE040 is supplied in bulk packaging. The T520B336M008ATE040 is supplied in Tape & Reel (TR) format. Both formats contain the same component with identical electrical and mechanical properties. Tape & Reel packaging is standard for automated assembly processes.

Q: Are there compliance differences between these parts?
