Key Parameters

Substitute Part Grouping Explanation

Substitution for the 6TPC47M is determined by the following criteria:

Primary Compatibility Parameters:

• Capacitance value: 47 µF (exact match required)
• Package / Case: 1411 (3528 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Type: Molded Tantalum Polymer (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (minimum requirement)
• RoHS Compliance: ROHS3 Compliant (required)

Secondary Consideration Parameters:

• Voltage Rating: May be equal to or higher than 6.3 V
• ESR (Equivalent Series Resistance): Lower values indicate improved performance
• Product Status: Active status preferred for long-term availability

Two substitute parts meet these criteria and are listed below.

Parameter Comparison

Engineering Selection Recommendations

10TPE47MAZB: This substitute maintains the exact 47 µF capacitance value with identical footprint dimensions (0.138" L x 0.110" W). The rated voltage is increased to 10 V, providing additional voltage margin above the 6.3 V requirement. ESR is reduced to 35 mOhm, improving performance characteristics. The part is Active status with established long-term availability. Height increases to 0.079" (2.00mm) compared to 0.047" (1.20mm) of the original part; PCB layout clearance must be verified. ROHS3 compliance and REACH Unaffected status are confirmed.

6TPS150MUD: This substitute provides the same 6.3 V voltage rating and maintains identical footprint dimensions (0.138" L x 0.110" W) and height (0.047" (1.20mm)). Capacitance is increased to 150 µF, which may be suitable for applications where higher capacitance provides design benefits. ESR is reduced to 30 mOhm, the lowest among all options. The part is Active status with higher inventory availability. ROHS3 compliance and REACH Unaffected status are confirmed. Lifetime rating of 2000 Hrs @ 105°C exceeds the original part specification.

Both substitutes are ROHS3 compliant and manufactured by the same supplier, ensuring consistency in quality and reliability standards.

Frequently Asked Questions (FAQ)

Q: Can 10TPE47MAZB be used as a direct replacement for 6TPC47M?

A: 10TPE47MAZB is functionally compatible for the 47 µF capacitance requirement and maintains the same footprint. The 10 V rating is higher than the 6.3 V requirement, which is acceptable in most applications. However, the seated height increases from 1.20mm to 2.00mm; PCB layout must accommodate this difference.

Q: What is the primary difference between the two substitute options?

A: 10TPE47MAZB maintains the 47 µF capacitance with higher voltage rating (10 V) and increased height (2.00mm). 6TPS150MUD maintains the 6.3 V voltage rating with higher capacitance (150 µF) and original height (1.20mm). Selection depends on circuit voltage requirements and available PCB clearance.

Q: Is 6TPS150MUD suitable if my circuit requires exactly 47 µF?

A: 6TPS150MUD provides 150 µF capacitance, which differs from the 47 µF specification. This substitute is appropriate only if the application circuit design permits higher capacitance values without adverse effects on circuit performance.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, both 10TPE47MAZB and 6TPS150MUD are ROHS3 compliant, matching the compliance status of the original 6TPC47M part.

Q: What is the significance of the Last Time Buy status for 6TPC47M?

A: Last Time Buy indicates the original part is at end-of-life. Panasonic will not manufacture additional units after existing inventory is depleted. Substitution planning is necessary for future production requirements.

Q: How do ESR values affect component selection?

A: Lower ESR values indicate reduced equivalent series resistance, which improves performance in high-frequency applications and reduces heat generation. Both substitutes offer lower ESR than the original part: 10TPE47MAZB at 35 mOhm and 6TPS150MUD at 30 mOhm, compared to 55 mOhm for 6TPC47M.
