Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6.3SLE47M1.4X7.3 is determined by the following critical parameters:

• Capacitance Value: 47 µF (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• Type: Aluminum Polymer (exact match required for electrical performance)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 3 (168 Hours) (handling and storage requirement)

The KEMET A700V476M006ATE018 meets all mandatory substitution criteria. While secondary parameters such as ESR, ripple current rating, and maximum height differ, these variations remain within acceptable ranges for general purpose applications and do not preclude functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The KEMET A700V476M006ATE018 is a direct functional equivalent for the Rubycon 6.3SLE47M1.4X7.3. Both parts are ROHS3 compliant and share identical capacitance, voltage rating, tolerance, package, and moisture sensitivity specifications. The KEMET part carries Active product status, ensuring continued availability and supply chain support.

The KEMET substitute offers an extended operating temperature range (-55°C ~ 125°C versus -55°C ~ 105°C) and higher ripple current capability (3.9 A versus 3 A at 100 kHz), providing enhanced performance margins in general purpose applications. The increased maximum height (2.00 mm versus 1.40 mm) must be evaluated against specific PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the KEMET A700V476M006ATE018 be used as a direct replacement for the Rubycon 6.3SLE47M1.4X7.3?

A: Yes. Both parts share identical capacitance (47 µF), voltage rating (6.3 V), tolerance (±20%), package (2917 / 7343 Metric), and mounting type (Surface Mount). Both are ROHS3 compliant with MSL 3 rating.

Q: What is the significance of the different ESR values (9 mOhm vs. 18 mOhm)?

A: ESR affects heat dissipation and ripple current handling. The KEMET part has higher ESR but compensates with higher ripple current rating (3.9 A versus 3 A at 100 kHz), maintaining suitability for general purpose applications.

Q: Does the height difference (1.40 mm vs. 2.00 mm) affect compatibility?

A: Height difference must be evaluated against specific PCB layout and clearance requirements. The KEMET part is taller and may require clearance verification in space-constrained designs.

Q: Why is the Rubycon part marked "Not For New Designs"?

A: This designation indicates end-of-life status. The KEMET A700V476M006ATE018 with Active status is recommended for new designs and ongoing production.

Q: Are both parts suitable for the same operating temperature range?

A: The Rubycon part operates -55°C ~ 105°C, while the KEMET part operates -55°C ~ 125°C. The KEMET part supports a wider temperature range and is suitable for applications requiring the original -55°C ~ 105°C range.
