Equivalent & Substitute Parts for 2TPE330MFB

Part Overview

The 2TPE330MFB is a 330 µF molded tantalum polymer capacitor rated at 2 V, manufactured by Panasonic Electronic Components as part of the POSCAP™ TPE series. This component is designed for surface mount applications in the 1411 (3528 Metric) package format with an ESR of 15 mOhm @ 100kHz.

The 2TPE330MFB has reached obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this capacitor specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 2TPE330MFB is determined by the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Package / Case: 1411 (3528 Metric) (exact match required for mechanical compatibility)
• Mounting Type: Surface Mount (exact match required)
• ESR Specification: 15 mOhm @ 100kHz (exact match required for electrical performance)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Tolerance: ±20% (exact match required)

The ETPE330MFB qualifies as a direct substitute based on these parameters. While the rated voltage differs (2.5 V versus 2 V), the higher voltage rating of the substitute part maintains backward compatibility in applications designed for the original 2 V specification, as the substitute can safely operate at lower voltage levels.

Parameter Comparison

Engineering Selection Recommendations

The ETPE330MFB is the qualified substitute for the obsolete 2TPE330MFB. Both components are manufactured by Panasonic Electronic Components within the POSCAP™ TPE series and share identical electrical and mechanical specifications with the exception of rated voltage.

The substitute part maintains active product status, ensuring continued availability and supply chain support. Both parts are ROHS3 compliant and carry identical export classification codes (EAR99) and HTSUS codes (8532.21.0050), confirming regulatory equivalence.

The higher voltage rating (2.5 V) of the ETPE330MFB provides design margin for applications originally specified at 2 V, with no adverse impact on circuit performance or reliability.

Frequently Asked Questions (FAQ)

Q: Can the ETPE330MFB replace the 2TPE330MFB in existing designs?

A: Yes. The ETPE330MFB is a direct substitute. All critical electrical parameters (capacitance, ESR, operating temperature range, tolerance) and mechanical specifications (package, dimensions, mounting type) are identical. The higher voltage rating of the substitute part is compatible with 2 V circuit applications.

Q: Are there any packaging differences between these parts?

A: The main part (2TPE330MFB) is supplied in standard packaging, while the substitute (ETPE330MFB) is supplied in Tape & Reel (TR) format. Both use the identical 1411 (3528 Metric) package case with matching physical dimensions and mounting characteristics.

Q: What is the significance of the voltage rating difference?

A: The ETPE330MFB is rated at 2.5 V compared to the 2 V rating of the original part. In circuit applications, a higher voltage-rated capacitor can safely operate at lower voltages. This provides additional design margin and does not compromise performance or reliability.

Q: Are both parts RoHS compliant?

A: Yes. Both the 2TPE330MFB and ETPE330MFB are ROHS3 compliant, confirming equivalent environmental and regulatory status.

Q: What is the availability status of these parts?

A: The 2TPE330MFB is obsolete. The ETPE330MFB maintains active product status with current inventory availability, making it the recommended choice for new procurement and ongoing production support.
