Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 8SW68M2.7X7.3 is determined by the following critical parameters:

• Capacitance Value: Must be 68 µF
• Voltage Rating: Must be 8 V or higher
• Tolerance: Must be ±20% or tighter
• Package Type: Must be 2917 (7343 Metric)
• Mounting Type: Must be Surface Mount
• Type: Must be Aluminum Polymer
• Operating Temperature Range: Must encompass -55°C to 105°C minimum
• RoHS Compliance: Must maintain ROHS3 Compliant status
• MSL Rating: Must be 3 or lower

The KEMET A700D686M008ATE015 meets all substitution criteria. It maintains identical capacitance, voltage, tolerance, package, and mounting specifications while offering improved electrical performance characteristics and active product status.

Parameter Comparison

Engineering Selection Recommendations

The KEMET A700D686M008ATE015 is a direct functional substitute for the Rubycon 8SW68M2.7X7.3. Both parts maintain identical electrical specifications for capacitance, voltage rating, and tolerance. The KEMET part offers superior performance characteristics: lower ESR (15mOhm versus 18mOhm), extended temperature rating to 125°C, and active product status ensuring continued availability and manufacturing support.

The KEMET substitute maintains full RoHS3 compliance and identical MSL rating, ensuring compatibility with existing assembly and storage protocols. The 0.40mm increase in seated height (3.10mm versus 2.70mm) must be evaluated against specific PCB layout constraints and clearance requirements in the target application.

Frequently Asked Questions (FAQ)

Q: Can the KEMET A700D686M008ATE015 be used as a direct replacement for the Rubycon 8SW68M2.7X7.3?

A: Yes. Both parts share identical capacitance (68 µF), voltage rating (8 V), tolerance (±20%), package type (2917 / 7343 Metric), and mounting configuration (Surface Mount). Electrical and mechanical compatibility is established.

Q: What is the significance of the height difference between these parts?

A: The KEMET substitute has a maximum seated height of 3.10mm compared to 2.70mm for the Rubycon original. This 0.40mm difference must be verified against PCB layout clearances, component stacking requirements, and enclosure constraints in the specific application.

Q: Why does the KEMET part have a lower ESR value?

A: The KEMET A700D686M008ATE015 demonstrates improved electrical performance with 15mOhm ESR versus 18mOhm for the Rubycon part. Lower ESR reduces heat generation and improves ripple current handling capability, representing a performance enhancement in the substitute.

Q: Does the extended temperature rating of the KEMET part affect compatibility?

A: No. The KEMET part's operating range of -55°C to 125°C encompasses the original -55°C to 105°C specification. Extended temperature capability does not compromise compatibility and provides additional operational margin.

Q: Are both parts RoHS compliant?

A: Yes. Both the Rubycon 8SW68M2.7X7.3 and KEMET A700D686M008ATE015 are ROHS3 Compliant with identical MSL ratings of 3 (168 Hours), ensuring equivalent compliance with environmental and storage requirements.

Q: What is the packaging difference between these parts?

A: The Rubycon original is supplied in Tape & Reel (TR) packaging, while the KEMET substitute is supplied in Cut Tape (CT) packaging. Both are standard surface mount delivery formats; packaging selection depends on assembly line requirements and order quantities.
