Key Parameters

Substitute Part Grouping Explanation

Substitution for the 2TPF220M6 is determined by the following critical parameters:

Electrical Compatibility: Capacitance value, voltage rating, ESR characteristics, and operating temperature range must support the original application requirements. Substitute parts must maintain equivalent or superior electrical performance.

Mechanical Compatibility: Package type (2917 / 7343 Metric), surface mount configuration, and physical dimensions must allow direct board-level replacement without layout modifications.

Regulatory Compliance: RoHS3 compliance and ECCN classification must match or exceed the original specification.

The substitute parts listed below satisfy these criteria within the allowed parameter tolerances for tantalum polymer capacitor technology.

Parameter Comparison

Engineering Selection Recommendations

KEMET T520V227M006ATE007 is the direct equivalent substitute. This part maintains identical capacitance (220 µF), package footprint (2917 / 7343 Metric), and physical dimensions as the original 2TPF220M6. The higher voltage rating (6.3 V vs. 2 V) provides design margin in low-voltage applications. ESR performance is comparable at 7 mOhm versus 6 mOhm. Both parts are ROHS3 compliant and rated for 2000 hours at 105°C. This part is currently in active production status with 2407 units in stock.

Panasonic ETPSF270M6E is an alternative substitute with higher capacitance (270 µF) and voltage rating (2.5 V). This part uses a smaller package footprint (1411 / 3528 Metric), which requires PCB layout modification and is not a direct mechanical replacement. The reduced lifetime rating (1000 Hrs @ 105°C vs. 2000 Hrs) should be evaluated against application requirements. This part is currently in active production status with 18830 units in stock.

For direct board-level replacement without design changes, the KEMET T520V227M006ATE007 is the recommended selection. The Panasonic ETPSF270M6E is suitable only when PCB layout modifications are acceptable and the higher capacitance value is beneficial to the application.

Frequently Asked Questions (FAQ)

Q: Can the KEMET T520V227M006ATE007 be used as a direct replacement for the Panasonic 2TPF220M6?

A: Yes. Both parts share identical capacitance (220 µF), package type (2917 / 7343 Metric), and physical dimensions (0.287" L x 0.169" W). The higher voltage rating of the KEMET part (6.3 V vs. 2 V) is compatible with 2 V applications and provides additional design margin. Surface mount configuration and operating temperature range are equivalent.

Q: Why is the Panasonic ETPSF270M6E listed as a substitute if it uses a different package?

A: The ETPSF270M6E is listed as a manufacturer-recommended alternative for applications where higher capacitance (270 µF) and voltage rating (2.5 V) are acceptable. However, the smaller package footprint (1411 / 3528 Metric) requires PCB layout redesign and is not a direct mechanical replacement. This part is suitable only when design modifications are feasible.

Q: What are the key electrical differences between these substitute parts?

A: The KEMET T520V227M006ATE007 maintains the original 220 µF capacitance with a higher voltage rating (6.3 V). ESR is slightly higher at 7 mOhm compared to 6 mOhm. The Panasonic ETPSF270M6E increases capacitance to 270 µF with a 2.5 V rating and maintains 6 mOhm ESR, but uses a smaller package requiring layout changes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The KEMET T520V227M006ATE007 and Panasonic ETPSF270M6E are both ROHS3 compliant, matching the original 2TPF220M6 specification.

Q: What is the impact of the different lifetime ratings?

A: The original 2TPF220M6 and KEMET T520V227M006ATE007 are both rated for 2000 hours at 105°C. The Panasonic ETPSF270M6E has a reduced lifetime rating of 1000 hours at 105°C. Applications requiring extended operational life at elevated temperatures should prioritize parts with the 2000-hour rating.
