Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the T520V227M004ASE009 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance: 220 µF (exact match required)
• Voltage Rating: 4 V (exact match required)
• ESR: 9 mOhm @ 100kHz (exact match required)
• Tolerance: ±20% (exact match required)

Mechanical Parameters:

• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Size / Dimension: 0.287" L x 0.169" W (7.30mm x 4.30mm) (exact match required)
• Height - Seated (Max): 0.075" (1.90mm) (exact match required)

Environmental Parameters:

• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Lifetime @ Temp.: 2000 Hrs @ 105°C (exact match required)
• Moisture Sensitivity Level: 3 (168 Hours) (exact match required)

Type Classification:

• Type: Molded Tantalum Polymer (exact match required)
• Series: KO-CAP® T520 (exact match required)

Substitute parts must satisfy all parameters listed above without deviation. Packaging format (tape & reel versus bulk) does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The T520V227M004ATE009 is the direct substitute for the obsolete T520V227M004ASE009. Both components are manufactured by KEMET within the KO-CAP® T520 series and share identical electrical, mechanical, and environmental specifications.

Product Status Consideration: The T520V227M004ASE009 is classified as obsolete, while the T520V227M004ATE009 maintains active product status. This distinction is significant for long-term supply chain planning and component availability.

Compliance Consideration: The T520V227M004ATE009 is ROHS3 compliant, whereas the T520V227M004ASE009 is RoHS non-compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the substitute part satisfies these requirements.

Packaging Consideration: The T520V227M004ATE009 is supplied in Tape & Reel (TR) format, while the T520V227M004ASE009 is supplied in bulk packaging. This difference affects procurement and assembly processes but does not alter component performance or compatibility.

All other parameters—capacitance, voltage rating, ESR, package dimensions, operating temperature range, lifetime rating, and moisture sensitivity—are identical between the main part and substitute part.

Frequently Asked Questions (FAQ)

Q: Can the T520V227M004ATE009 be used as a direct replacement for the T520V227M004ASE009?

A: Yes. The T520V227M004ATE009 is electrically and mechanically equivalent to the T520V227M004ASE009. All critical parameters including capacitance (220 µF), voltage rating (4 V), ESR (9 mOhm @ 100kHz), package dimensions (2917 / 7343 Metric), and operating specifications are identical.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging format. The T520V227M004ASE009 is obsolete and supplied in bulk packaging. The T520V227M004ATE009 is an active product supplied in Tape & Reel format and carries ROHS3 compliance certification, whereas the original part is RoHS non-compliant.

Q: Will the substitute part fit in the same PCB footprint?

A: Yes. Both parts 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). No PCB redesign is required.

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts are rated at 220 µF capacitance with ±20% tolerance, 4 V voltage rating, and 9 mOhm ESR @ 100kHz. Operating temperature range (-55°C ~ 105°C) and lifetime rating (2000 Hrs @ 105°C) are identical.

Q: What is the significance of the packaging format difference?

A: The T520V227M004ASE009 is supplied in bulk packaging, while the T520V227M004ATE009 is supplied in Tape & Reel (TR) format. This affects procurement logistics and automated assembly processes but does not impact electrical or mechanical performance.

Q: Is the substitute part RoHS compliant?

A: Yes. The T520V227M004ATE009 is ROHS3 compliant. The original T520V227M004ASE009 is RoHS non-compliant. For applications requiring RoHS compliance, the substitute part meets this requirement.

Q: Are both parts from the same manufacturer?

A: Yes. Both the T520V227M004ASE009 and T520V227M004ATE009 are manufactured by KEMET and belong to the KO-CAP® T520 series.

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

A: Both parts carry a Moisture Sensitivity Level (MSL) rating of 3, which corresponds to a maximum floor life of 168 hours under specified humidity conditions.
