Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 6TPU47MSI is determined by strict equivalence across the following parameters:

• Capacitance value: 47 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Type: Molded Tantalum Polymer (exact match required)
• ESR @ 100kHz: 150 mOhm (exact match required)
• Tolerance: ±20% (exact match required)
• RoHS Status: ROHS3 Compliant (minimum requirement)

The substitute part F380J476MSAAH1 manufactured by KYOCERA AVX meets all mandatory electrical and mechanical parameters for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

F380J476MSAAH1 is qualified as a direct substitute for 6TPU47MSI based on electrical and mechanical parameter equivalence. Both components are ROHS3 compliant and share identical capacitance, voltage rating, ESR characteristics, and package specifications.

The F380J476MSAAH1 carries a product status of "Not For New Designs," indicating it is also subject to obsolescence considerations. The extended operating temperature range of -55°C ~ 105°C in the KYOCERA AVX part provides additional thermal margin compared to the original Panasonic specification of -55°C ~ 85°C.

Selection between these parts should be based on availability, supply chain continuity, and application-specific thermal requirements within the specified operating ranges.

Frequently Asked Questions (FAQ)

Q: Can F380J476MSAAH1 be used as a direct replacement for 6TPU47MSI in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 47 µF capacitance, 6.3 V rating, 150 mOhm ESR @ 100kHz, 0805 package, and ±20% tolerance. No circuit modifications are required.

Q: What is the difference in physical dimensions between these parts?

A: Both parts conform to 0805 (2012 Metric) package specifications with identical length and width (0.079" L x 0.049" W / 2.00mm x 1.25mm). The seated height differs slightly: 6TPU47MSI is 0.039" (1.00mm) maximum, while F380J476MSAAH1 is 0.035" (0.90mm) maximum. This difference does not affect PCB layout or assembly compatibility.

Q: Are there thermal performance differences between these parts?

A: Both parts specify 1000 hours lifetime at 85°C. The F380J476MSAAH1 supports an extended operating temperature range to 105°C, compared to 85°C for the 6TPU47MSI. Applications operating within the original 6TPU47MSI temperature range experience equivalent thermal performance.

Q: What is the packaging difference between these parts?

A: The 6TPU47MSI is supplied in standard packaging, while F380J476MSAAH1 is supplied in Tape & Reel (TR) format. Both are surface mount compatible and suitable for automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both 6TPU47MSI and F380J476MSAAH1 are ROHS3 compliant and meet environmental regulatory requirements.
