3. Manufacturer Continuity: Both the original and substitute are manufactured by Panasonic Electronic Components, ensuring consistent quality standards and design philosophy.

4. Electrical Equivalence: Identical 470 µF capacitance value with specified voltage rating of 4 V, ESR of 25 mOhm @ 100kHz, and operating temperature range of -55°C ~ 105°C provides direct functional replacement.

5. Packaging Standardization: The 2917 (7343 Metric) package represents current industry standard surface mount packaging for tantalum polymer capacitors in this capacitance range.

Frequently Asked Questions (FAQ)

Q: Why is the 4TPB470M classified as obsolete?

A: The 4TPB470M has reached end-of-life status in Panasonic's product portfolio. Obsolete classification indicates the manufacturer no longer produces this component and has transitioned customers to newer equivalent designs such as the 4TPE470ML.

Q: Is the 4TPE470ML a direct replacement for the 4TPB470M?

A: Yes. Both components share the same 470 µF capacitance value and are manufactured by Panasonic Electronic Components. The 4TPE470ML is the manufacturer-recommended substitute and provides electrical and mechanical equivalence for the obsolete 4TPB470M.

Q: What are the key electrical parameters that must match for substitution?

A: The critical parameters for tantalum polymer capacitor substitution are capacitance value (470 µF), voltage rating (4 V or higher), and ESR characteristics (25 mOhm @ 100kHz). These parameters determine functional compatibility in the application circuit.

Q: Does the 4TPE470ML meet current regulatory requirements?

A: Yes. The 4TPE470ML is RoHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic component procurement in most jurisdictions.

Q: What is the package size difference between the original and substitute?

A: The 4TPE470ML uses the 2917 (7343 Metric) surface mount package with dimensions of 0.287" L x 0.169" W (7.30mm x 4.30mm) and maximum seated height of 0.118" (3.00mm). Original package specifications for the 4TPB470M are not documented in available technical data.

Q: Is inventory availability a concern for the 4TPB470M?

A: Current inventory of the obsolete 4TPB470M is 6276 pieces. However, once this stock is depleted, no additional units will be manufactured. The 4TPE470ML maintains active production status with 2798 pieces currently in stock, ensuring continued availability for new designs and replacements.

Q: What is the operating temperature range for the substitute part?

A: The 4TPE470ML operates across -55°C to 105°C with a rated lifetime of 2000 hours at 105°C, providing reliable performance across standard industrial and commercial temperature ranges.
