• Package type: 2917 (7343 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C to 105°C (minimum requirement)
• Lifetime rating: 2000 Hrs @ 105°C (minimum requirement)
• Tolerance: ±20% (exact match required)
• Compliance: ROHS3 Compliant (required)

The EEF-CX0J101R from Panasonic Electronic Components meets all substitution criteria for the 6SW100MX within these defined parameters.

Parameter Comparison

Engineering Selection Recommendations

The EEF-CX0J101R qualifies as a direct substitute for the 6SW100MX based on matching electrical specifications and package dimensions. The Panasonic component carries an "Active" product status, making it suitable for new design implementations. Both components maintain ROHS3 compliance and identical electrical ratings for capacitance, voltage, tolerance, and lifetime specifications.

The EEF-CX0J101R exhibits a higher ESR value (15 mOhm versus 9 mOhm) and a lower seated height (1.90 mm versus 2.70 mm). These differences must be evaluated within the context of specific circuit requirements and PCB layout constraints. The lower profile of the Panasonic component may provide advantages in space-constrained applications, while the higher ESR may impact performance in ripple current-sensitive circuits.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0J101R replace the 6SW100MX in existing designs?

A: Yes. Both components share identical capacitance (100 µF), voltage rating (6.3 V), tolerance (±20%), package type (2917 Metric), and thermal lifetime specifications (2000 Hrs @ 105°C). The components are mechanically and electrically compatible for direct substitution.

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

A: The 6SW100MX has an ESR of 9 mOhm while the EEF-CX0J101R has an ESR of 15 mOhm. ESR affects ripple current handling and thermal performance. Applications with high ripple current requirements should verify that the higher ESR of the substitute part remains within acceptable operating parameters.

Q: Are there height considerations for PCB layout?

A: Yes. The 6SW100MX has a maximum seated height of 2.70 mm, while the EEF-CX0J101R measures 1.90 mm. The lower profile of the Panasonic component may require PCB layout verification to ensure clearance compatibility, particularly in applications with height restrictions.

Q: Do both parts meet current compliance requirements?

A: Both the 6SW100MX and EEF-CX0J101R are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Why is the 6SW100MX marked "Not For New Designs"?

A: This designation indicates that while existing inventory is available, Rubycon recommends that new design implementations select alternative components. The EEF-CX0J101R, with its "Active" product status, represents a current-generation alternative suitable for new applications.
