Key Parameters

Substitute Part Grouping Explanation

Substitution of the 6SLG47MX is determined by strict equivalence in the following parameters:

• Capacitance value: 47 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: 2917 (7343 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Component type: Aluminum Polymer (exact match required)

The KEMET A700V476M006ATE018 meets all substitution criteria. While this part exhibits improved electrical characteristics (lower ESR, higher ripple current capability, extended temperature range), these enhancements do not disqualify it as a direct substitute. The part maintains identical capacitance, voltage, tolerance, and package specifications.

Parameter Comparison

Engineering Selection Recommendations

The KEMET A700V476M006ATE018 is a direct functional equivalent to the Rubycon 6SLG47MX. Both parts are ROHS3 compliant and carry identical MSL ratings. The KEMET part holds Active product status, whereas the Rubycon part is designated Not For New Designs. For applications requiring continued supply or new production, the A700V476M006ATE018 provides equivalent electrical performance with enhanced specifications in ESR, ripple current handling, and temperature range. The increased seated height (2.00 mm versus 1.10 mm) must be evaluated against PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the KEMET A700V476M006ATE018 be used as a direct replacement for the Rubycon 6SLG47MX?

A: Yes. Both parts share identical capacitance (47 µF), voltage rating (6.3 V), tolerance (±20%), package type (2917 Metric), and mounting configuration (Surface Mount). Electrical performance is equivalent within the specified parameters.

Q: What is the primary difference between these two parts?

A: The KEMET part exhibits lower ESR (18 mOhm versus 15 mOhm), higher ripple current capability (3.9 A versus 2.1 A at 100 kHz), and an extended operating temperature range (-55°C to 125°C versus -55°C to 105°C). The KEMET part also has a greater seated height (2.00 mm versus 1.10 mm).

Q: Does the height difference affect PCB compatibility?

A: The KEMET A700V476M006ATE018 has a maximum seated height of 2.00 mm compared to 1.10 mm for the Rubycon part. PCB layout and component clearance requirements must be evaluated to confirm physical compatibility in the target application.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both the 6SLG47MX and A700V476M006ATE018 are ROHS3 compliant and REACH unaffected. Both carry MSL rating 3 (168 Hours).

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

A: This designation indicates the manufacturer is discontinuing the product line. For new production or long-term supply assurance, the KEMET A700V476M006ATE018 is the recommended alternative.
