Key Parameters

Substitute Part Grouping Explanation

Substitution of the T520V227M2R5ASE045 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Capacitance value: 220 µF (exact match required)
• Voltage rating: 2.5 V (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• ESR @ 100 kHz: 45 mOhm (exact match required)
• Mounting type: Surface Mount (exact match required)

Secondary Compatibility Parameters:

• Operating temperature range: -55°C to 105°C (must meet or exceed)
• Tolerance: ±20% (must match)
• Moisture sensitivity level: 3 (168 Hours) (must match)

The T520V227M2R5ASE045 differs from its substitute primarily in packaging format (tube versus tape & reel) and product status (obsolete versus active). The direct substitute T520V227M2R5ATE045 maintains identical electrical and mechanical specifications while offering active product status and improved supply availability.

Engineering Selection Recommendations

Primary Recommendation: T520V227M2R5ATE045

The T520V227M2R5ATE045 is the direct functional equivalent of the T520V227M2R5ASE045. This substitute maintains identical electrical performance and mechanical compatibility while offering the following advantages:

• Active product status ensures ongoing availability and supply chain support
• ROHS3 compliance aligns with current environmental and regulatory standards
• Tape & Reel packaging format supports automated assembly processes
• Equivalent inventory availability (1103 Pcs in stock)

The substitution is valid for all applications where the original T520V227M2R5ASE045 was specified, provided that packaging format and compliance requirements are compatible with the end application.

Frequently Asked Questions (FAQ)

Q: Can the T520V227M2R5ATE045 be used as a direct replacement for the T520V227M2R5ASE045?

A: Yes. Both parts are electrically and mechanically identical. The primary differences are packaging format (tape & reel versus tube) and product status (active versus obsolete). Substitution is valid provided the receiving system can accommodate tape & reel packaging.

Q: What is the significance of the packaging format difference (ASE versus ATE)?

A: The ASE designation indicates tube packaging, while ATE indicates tape & reel packaging. Both formats contain the same component. Tape & reel packaging is standard for high-volume automated assembly, while tube packaging is typically used for lower-volume or manual assembly applications.

Q: Does the ROHS3 compliance of the T520V227M2R5ATE045 affect electrical performance?

A: No. ROHS3 compliance is a material composition and environmental standard. It does not alter the electrical specifications, performance characteristics, or functional behavior of the capacitor.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both the T520V227M2R5ASE045 and T520V227M2R5ATE045 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). They are fully compatible for PCB layout and assembly.

Q: What is the moisture sensitivity level, and does it affect handling?

A: Both parts carry MSL 3 (168 Hours) rating. This indicates the component must be stored in controlled humidity conditions and has a 168-hour floor life after exposure to ambient conditions. Standard moisture-barrier packaging and handling procedures apply.
