Key Parameters

Substitute Part Grouping Explanation

Substitution of the 8SW100M2.7X7.3 is determined by the following critical parameters:

• Capacitance value: 100 µF (exact match required)
• Voltage rating: 8 V (minimum; higher ratings are acceptable)
• Package type: 2917 (7343 Metric) (physical and electrical compatibility)
• Mounting type: Surface Mount (PCB assembly compatibility)
• Tolerance: ±20% (functional equivalence in circuit operation)
• Dielectric type: Aluminum Polymer (electrical characteristics and performance profile)

The KEMET A700X107M008ATE012 meets all substitution criteria. Both parts share identical capacitance, voltage rating, package dimensions, and tolerance specifications. The substitute part operates across an extended temperature range (-55°C ~ 125°C versus -55°C ~ 105°C) and features improved ESR performance (12 mOhm versus 18 mOhm), making it functionally compatible and electrically superior for the same application space.

Parameter Comparison

Engineering Selection Recommendations

The KEMET A700X107M008ATE012 is the qualified substitute for the 8SW100M2.7X7.3. Selection is supported by the following factors:

• Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements
• Identical package footprint (2917 / 7343 Metric) ensures direct PCB compatibility without layout modification
• Matching capacitance, voltage, and tolerance specifications guarantee functional equivalence in circuit operation
• The KEMET part carries active product status, ensuring ongoing availability and supply chain reliability
• Superior ESR performance (12 mOhm versus 18 mOhm) and extended temperature rating (-55°C ~ 125°C) provide enhanced performance margins in thermal and electrical stress conditions
• Moisture sensitivity level (MSL 3) is identical, maintaining equivalent handling and storage requirements

Frequently Asked Questions (FAQ)

Q: Can the KEMET A700X107M008ATE012 be used as a direct replacement for the Rubycon 8SW100M2.7X7.3?

A: Yes. Both parts share identical capacitance (100 µF), voltage rating (8 V), tolerance (±20%), and package type (2917 / 7343 Metric). The KEMET part is electrically and mechanically compatible for direct substitution without circuit redesign or PCB modification.

Q: What are the key differences between these two parts?

A: The primary differences are product status, ESR, and operating temperature range. The Rubycon part is not for new designs, while the KEMET part is active. The KEMET part features lower ESR (12 mOhm versus 18 mOhm) and operates to 125°C versus 105°C, providing improved thermal performance and reduced impedance characteristics.

Q: Are there any package or mounting considerations when substituting?

A: No. Both parts use the 2917 (7343 Metric) package with surface mount technology. PCB land patterns, reflow profiles, and assembly processes remain unchanged. Moisture sensitivity level (MSL 3) is identical for both parts.

Q: Does the substitute part meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected. Regulatory and environmental compliance requirements are equivalent.

Q: Why is the Rubycon part marked as not for new designs?

A: This designation indicates the part has been superseded in Rubycon's active product portfolio. The KEMET A700X107M008ATE012 represents the current-generation equivalent with improved specifications and active manufacturing status.
