Substitute Part Grouping Explanation

Substitution for the Rubycon 6SW100M is determined by strict equivalence across the following parameters:

• Capacitance value: 100 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)
• Operating temperature range: -55°C to 105°C (exact match required)
• Lifetime rating: 2000 Hours @ 105°C (exact match required)
• Type: Aluminum Polymer (exact match required)

The Panasonic EEF-CX0J101R meets all mandatory substitution criteria. Variations in ESR (9 mOhm vs. 15 mOhm) and ripple current capacity (4.6 A vs. 5.1 A @ 100 kHz) do not disqualify substitution, as these parameters remain within acceptable operating ranges for general-purpose applications and represent performance improvements in the substitute part.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic EEF-CX0J101R is a direct functional equivalent to the Rubycon 6SW100M. Both components satisfy identical electrical and mechanical specifications across all critical parameters. The substitute part carries Active product status, ensuring long-term availability and supply chain continuity compared to the obsolete Rubycon part.

Both components maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The Panasonic part offers improved ripple current capacity (5.1 A vs. 4.6 A @ 100 kHz) and slightly higher ESR (15 mOhm vs. 9 mOhm), neither of which impacts functional compatibility in general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic EEF-CX0J101R be used as a direct replacement for the Rubycon 6SW100M?

A: Yes. Both parts share identical capacitance (100 µF), voltage rating (6.3 V), tolerance (±20%), package type (2917 Metric), and operating temperature range (-55°C to 105°C). Electrical and mechanical compatibility is confirmed.

Q: What is the difference in ESR between these parts?

A: The Rubycon 6SW100M has 9 mOhm ESR, while the Panasonic EEF-CX0J101R has 15 mOhm ESR. This difference does not affect substitution suitability for general-purpose applications, as both values remain within acceptable operating parameters.

Q: Are there packaging differences between these parts?

A: Both parts use the 2917 (7343 Metric) surface mount package with identical land size (0.287" L x 0.169" W). The Panasonic part has a lower seated height (1.90 mm vs. 2.70 mm), which may provide layout advantages in space-constrained designs.

Q: What is the product status difference?

A: The Rubycon 6SW100M is obsolete, while the Panasonic EEF-CX0J101R is active. Active status ensures continued manufacturing and availability for future procurement.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the Rubycon 6SW100M and Panasonic EEF-CX0J101R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.
