• Type: Molded Tantalum Polymer (exact match required)
• Operating Temperature: -55°C ~ 105°C (exact match required)
• Lifetime: 2000 Hrs @ 105°C (exact match required)
• Tolerance: ±20% (exact match required)

Direct Manufacturer Substitute: T520V227M006ATE040 is a direct equivalent from KEMET's KO-CAP® T520 series with identical electrical and mechanical specifications. This part is active and RoHS3 compliant.

Parametric Equivalent Substitute: T522V227M006ATE040 is from KEMET's KO-CAP® T522 series and meets all electrical and mechanical parameters identically. This part is active and RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production: Use T520V227M006ATE040 as the primary substitute. This part is a direct equivalent within the same KO-CAP® T520 series, maintains identical electrical and mechanical specifications, and is currently active with RoHS3 compliance. The transition from the obsolete T520V227M006ASE040 to T520V227M006ATE040 requires no circuit redesign or PCB layout modifications.

Alternative Selection: T522V227M006ATE040 is a valid parametric equivalent from the KO-CAP® T522 series. All electrical and mechanical parameters are identical, and the part is active with RoHS3 compliance. Selection between T520V227M006ATE040 and T522V227M006ATE040 depends on supply chain availability and procurement lead times, as both meet all functional requirements.

Compliance Consideration: Both substitute parts are RoHS3 compliant, whereas the original T520V227M006ASE040 is RoHS non-compliant. This compliance upgrade is beneficial for applications subject to RoHS regulations.

Frequently Asked Questions (FAQ)

Q: Can T520V227M006ATE040 be used as a direct replacement for T520V227M006ASE040? A: Yes. T520V227M006ATE040 is a direct equivalent with identical capacitance (220 µF), voltage rating (6.3 V), ESR (40 mOhm @ 100 kHz), package (2917 / 7343 Metric), and all other electrical and mechanical specifications. No circuit or PCB modifications are required.

Q: What is the difference between T520V227M006ATE040 and T522V227M006ATE040? A: Both parts are parametrically equivalent with identical electrical and mechanical specifications. The difference is the series designation: T520V227M006ATE040 belongs to the KO-CAP® T520 series, while T522V227M006ATE040 belongs to the KO-CAP® T522 series. Both are active and RoHS3 compliant.

Q: Are the substitute parts pin-compatible with the original part? A: Yes. Both substitute parts use the same 2917 (7343 Metric) surface mount package with identical dimensions (0.287" L x 0.169" W / 7.30mm x 4.30mm) and maximum seated height (0.075" / 1.90mm). PCB footprints are interchangeable.

Q: What is the MSL rating, and does it affect substitution? A: All three parts share the same MSL rating of 3 (168 Hours). This moisture sensitivity level is identical across the main part and both substitutes, ensuring equivalent handling and storage requirements.

Q: Why is the original part obsolete? A: The T520V227M006ASE040 is listed as obsolete by KEMET. The active substitutes T520V227M006ATE040 and T522V227M006ATE040 provide continued availability with improved RoHS3 compliance.

Q: Can these parts be used in high-temperature applications? A: Yes. All three parts operate across the temperature range -55°C ~ 105°C with a lifetime rating of 2000 hours at 105°C, making them suitable for applications requiring extended temperature performance.

Q: Is there a difference in packaging between the parts? A: No. All three parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
