Panasonic 2TPF330M6 Equivalent & Substitute Parts

Part Overview

The Panasonic 2TPF330M6 is a 330 µF molded tantalum polymer capacitor rated at 2 V, housed in a 2917 (7343 Metric) surface mount package. This component belongs to the POSCAP™ TPF series and is designated as Last Time Buy, indicating discontinued production. The part features 6 mOhm equivalent series resistance at 100 kHz and operates across -55°C to 105°C with a 2000-hour lifetime rating at 105°C. Alternative components are necessary due to the Last Time Buy status and limited inventory availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 2TPF330M6 is evaluated based on the following critical parameters: capacitance value, voltage rating, ESR characteristics, package compatibility, and thermal performance. Two substitute parts are identified with different substitution profiles:

ETPSF270M6E (MFR Recommended): This Panasonic POSCAP™ TPSF series component shares the same 6 mOhm ESR specification and operating temperature range. The capacitance is reduced to 270 µF with a higher voltage rating of 2.5 V. The package is smaller (1411 / 3528 Metric) but maintains surface mount compatibility. This substitute is suitable for applications where the higher voltage rating and lower capacitance are acceptable trade-offs.

T520V337M006ATE015 (Direct Manufacturer): This KEMET KO-CAP® T520 series component maintains the identical 330 µF capacitance and 2917 package footprint. The voltage rating is elevated to 6.3 V, and the ESR is increased to 15 mOhm at 100 kHz. The lifetime rating matches at 2000 hours at 105°C. This substitute provides direct package compatibility with modified electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

For ETPSF270M6E Selection: This substitute is appropriate when circuit design permits a 270 µF capacitance value and the application benefits from the higher 2.5 V voltage margin. The identical 6 mOhm ESR ensures equivalent ripple current performance. The reduced package footprint (1411 vs. 2917) requires PCB layout verification. The 1000-hour lifetime at 105°C is half that of the original specification and must be evaluated against application duty cycle requirements. Both components maintain ROHS3 compliance and REACH unaffected status.

For T520V337M006ATE015 Selection: This substitute maintains the original 330 µF capacitance and identical 2917 package footprint, eliminating PCB redesign requirements. The 6.3 V voltage rating provides increased design margin for the 2 V application. The 15 mOhm ESR represents a 2.5× increase over the original specification and affects ripple current handling and thermal performance. The 2000-hour lifetime at 105°C matches the original part. ROHS3 compliance and REACH unaffected status are maintained. Moisture Sensitivity Level (MSL) is rated at 3 (168 Hours).

Frequently Asked Questions (FAQ)

Q: Can ETPSF270M6E be used as a direct drop-in replacement?

A: No. While the ETPSF270M6E shares the same ESR and operating temperature range, the reduced capacitance (270 µF vs. 330 µF) and smaller package footprint (1411 vs. 2917) require circuit analysis and PCB layout modification. The 1000-hour lifetime at 105°C is also reduced compared to the original 2000-hour specification.

Q: What are the implications of the higher ESR in T520V337M006ATE015?

A: The T520V337M006ATE015 exhibits 15 mOhm ESR compared to 6 mOhm in the original part. This increases impedance at 100 kHz, affecting ripple current capacity and generating additional heat dissipation. Applications sensitive to ESR performance must evaluate this trade-off against the benefit of maintaining identical capacitance and package footprint.

Q: Is the T520V337M006ATE015 a true drop-in replacement?

A: The T520V337M006ATE015 maintains the same 2917 package footprint and 330 µF capacitance, allowing PCB reuse without layout modification. However, the elevated ESR and higher voltage rating (6.3 V vs. 2 V) represent electrical differences that must be validated in the application circuit.

Q: How does the voltage rating difference affect substitution?

A: The original 2TPF330M6 is rated at 2 V. ETPSF270M6E is rated at 2.5 V, and T520V337M006ATE015 is rated at 6.3 V. Higher voltage ratings provide design margin but do not affect compatibility in applications operating below the rated voltage. Circuit voltage stress analysis is required to confirm suitability.

Q: What is the impact of the reduced lifetime in ETPSF270M6E?

A: The ETPSF270M6E is rated for 1000 hours at 105°C, compared to 2000 hours for the original part. Applications with extended thermal stress or long operational life requirements must account for this reduced lifetime specification in reliability calculations.

Q: Are both substitutes compliant with environmental regulations?

A: Yes. Both ETPSF270M6E and T520V337M006ATE015 are ROHS3 compliant and REACH unaffected, matching the regulatory status of the original 2TPF330M6.
