Panasonic 6THC150M Tantalum Polymer Capacitor Equivalent & Substitute Parts

Part Overview

The Panasonic 6THC150M is a 150 µF molded tantalum polymer capacitor rated at 6.3 V in a 2917 (7343 Metric) surface mount package. This component is classified as Last Time Buy, indicating discontinued production. The part operates across -55°C to 125°C with a 1000-hour lifetime rating at 125°C and features 40 mOhm equivalent series resistance at 100 kHz. Identifying equivalent and substitute parts is necessary due to the Last Time Buy status and to support design flexibility across manufacturing batches and supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 6THC150M are identified based on the following critical parameters: capacitance value, voltage rating, package dimensions, mounting type, and operating temperature range. These parameters define functional interchangeability in circuit applications.

The 6TCE150M qualifies as a manufacturer-recommended direct equivalent, maintaining identical capacitance (150 µF), voltage rating (6.3 V), package (2917), and temperature range (-55°C to 125°C). The primary difference is improved ESR performance (25 mOhm versus 40 mOhm) and active product status.

The T55V227M6R3C0040 from Vishay Sprague is classified as a similar part with the same package, voltage rating, and temperature operating range. However, the capacitance differs at 220 µF, representing a higher value within the same voltage and package envelope. This part is suitable only when circuit design permits increased capacitance.

Parameter Comparison

Engineering Selection Recommendations

The 6TCE150M is the primary substitute for the 6THC150M. Both parts maintain identical electrical specifications for capacitance and voltage rating with matching package geometry and temperature operating range. The 6TCE150M offers superior ESR performance at 25 mOhm compared to 40 mOhm, providing improved high-frequency characteristics. The 6TCE150M carries Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the 6THC150M. Both parts are ROHS3 compliant.

The T55V227M6R3C0040 is suitable only when circuit design specifications permit a capacitance increase to 220 µF at the same 6.3 V rating and 2917 package. This part operates to 105°C maximum, which is lower than the 125°C rating of the primary part. Selection of this substitute requires verification that the higher capacitance value does not introduce unintended circuit behavior and that the reduced maximum operating temperature is acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can the 6TCE150M directly replace the 6THC150M without circuit modification?

A: Yes. The 6TCE150M maintains identical capacitance (150 µF), voltage rating (6.3 V), package dimensions (2917), and operating temperature range (-55°C to 125°C). The improved ESR specification (25 mOhm versus 40 mOhm) provides enhanced performance characteristics without requiring design changes.

Q: Is the T55V227M6R3C0040 a direct replacement?

A: No. While the T55V227M6R3C0040 shares the same package, voltage rating, and mounting type, the capacitance is increased to 220 µF. This part is suitable only when circuit design permits higher capacitance and when the reduced maximum operating temperature (105°C versus 125°C) is acceptable.

Q: What is the significance of the Last Time Buy status for the 6THC150M?

A: Last Time Buy indicates that Panasonic has discontinued production of this part. Existing inventory is available, but no future manufacturing runs are planned. Transitioning to the Active-status 6TCE150M ensures long-term supply chain continuity.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 6THC150M, 6TCE150M, and T55V227M6R3C0040 are all ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: What is the difference in ESR between the main part and the recommended substitute?

A: The 6THC150M has 40 mOhm ESR at 100 kHz, while the 6TCE150M has 25 mOhm ESR at 100 kHz. Lower ESR reduces impedance and improves performance in high-frequency filtering and power delivery applications.

Q: Can the 6TCE150M be used in applications requiring operation above 105°C?

A: Yes. The 6TCE150M is rated to 125°C, making it suitable for high-temperature applications. The T55V227M6R3C0040 is limited to 105°C and should not be used in applications requiring higher temperature operation.
