Engineering Selection Recommendations

KEMET T520V227M004ATE009 (4V Upgrade) This part maintains identical electrical performance and mechanical compatibility while providing increased voltage margin. The 4 V rating accommodates circuits requiring higher transient voltage tolerance. Both parts share the same ESR specification, operating temperature range, and lifetime rating. Suitable for direct substitution in applications where voltage headroom is beneficial.

KEMET T520V227M006ATE009 (6.3V Upgrade) This part provides maximum voltage margin within the T520 series while maintaining 220 µF capacitance and 9 mOhm ESR. The 6.3 V rating is appropriate for circuits with significant voltage transients or where design margin is critical. Identical package dimensions and thermal characteristics ensure mechanical compatibility.

KEMET T528Z227M004ATE009 and T528Z227M006ATE009 (T528 Series) These parts represent a series transition within KEMET's product portfolio. The T528 series offers reduced height (1.70 mm vs. 1.90 mm) while maintaining identical electrical specifications. Both 4 V and 6.3 V variants are available. The reduced profile accommodates space-constrained applications without compromising electrical performance.

KEMET T520V227M2R5ATE007 (Lower ESR Variant) This part maintains the 2.5 V rating and 220 µF capacitance while reducing ESR to 7 mOhm @ 100kHz. The improved ESR performance is beneficial in high-frequency ripple current applications. Identical package and thermal specifications ensure direct compatibility.

Panasonic 2R5TPE220M9 (Cross-Manufacturer Equivalent) This POSCAP™ TPE series part provides electrical equivalence with identical 220 µF capacitance, 2.5 V rating, and 9 mOhm ESR. The part is RoHS3 compliant and maintains the same operating temperature range and lifetime rating. Height is 2.00 mm (0.10 mm greater than T520V227M2R5ATE009). Suitable for applications where Panasonic sourcing is preferred or required.

All substitute parts maintain active production status and full RoHS3 compliance. Selection should be based on specific circuit requirements for voltage margin, ESR performance, and physical height constraints.

Frequently Asked Questions (FAQ)

Q: Can T520V227M004ATE009 (4V) be used in place of T520V227M2R5ATE009 (2.5V)?

A: Yes. The 4 V part is electrically and mechanically compatible. Higher voltage ratings are acceptable substitutes when the circuit design permits. The 4 V part provides additional voltage margin without changing capacitance, ESR, or thermal characteristics. Verify that the circuit board layout and component placement accommodate the identical 2917 package dimensions.

Q: What is the difference between T520 and T528 series parts?

A: Both series maintain identical electrical specifications (220 µF, 9 mOhm ESR, same voltage options). The primary difference is physical height: T520 series is 1.90 mm maximum, while T528 series is 1.70 mm maximum. The T528 series is suitable for applications with height constraints. Electrical performance and thermal ratings are equivalent.

Q: Is the Panasonic 2R5TPE220M9 a direct replacement?

A: The Panasonic part is electrically equivalent with matching 220 µF capacitance, 2.5 V rating, and 9 mOhm ESR. Physical dimensions are nearly identical (2917 package), with a maximum height of 2.00 mm compared to 1.90 mm for the KEMET part. The 0.10 mm height difference is negligible for most applications. Both parts are RoHS3 compliant and share identical operating temperature and lifetime specifications.

Q: Why would I choose T520V227M2R5ATE007 (7 mOhm) over the original part (9 mOhm)?

A: The lower ESR variant reduces impedance at 100 kHz, resulting in lower ripple voltage and improved transient response. This is beneficial in high-frequency switching applications or circuits with stringent ripple current requirements. The 7 mOhm part maintains all other specifications including 2.5 V rating, 220 µF capacitance, and 2917 package dimensions.

Q: Are all substitute parts available in the same packaging format?

A: The main part and most substitutes are available in Tape & Reel (TR) packaging. T520V227M006ATE009 is available in Cut Tape (CT) & Digi-Reel® format. Verify packaging requirements with your procurement specification before finalizing part selection.

Q: What is MSL 3 (168 Hours) and does it affect substitution?

A: MSL (Moisture Sensitivity Level) 3 indicates the component requires controlled storage conditions and has a floor life of 168 hours after bag opening. All listed substitute parts maintain MSL 3 rating, ensuring equivalent moisture handling requirements and storage protocols.

Q: Can I use a 6.3V part in a 2.5V circuit?

A: Yes. Higher voltage-rated capacitors are acceptable in lower voltage circuits. The 6.3 V part provides maximum design margin and is suitable for circuits with voltage transients or where reliability margin is prioritized. Verify that the circuit design does not require the specific ESR or physical height characteristics of the original 2.5 V part.
