Substitute Part Grouping Explanation

Substitution eligibility for the 2SW470M2.9X7.3 is determined by the following critical parameters:

• Capacitance Value: 470 µF (exact match required)
• Voltage Rating: 2 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 (minimum requirement)
• Lifetime Rating: 2000 Hrs @ 105°C (minimum requirement)
• Dielectric Type: Aluminum Polymer (exact match required)

The Panasonic EEF-GX0D471R meets all critical substitution criteria. Both components share identical electrical specifications, package dimensions, and environmental ratings. The substitute part is currently in Active product status, ensuring ongoing availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic EEF-GX0D471R is the qualified substitute for the Rubycon 2SW470M2.9X7.3. Both components satisfy identical electrical and mechanical requirements for 470 µF, 2 V aluminum polymer capacitor applications in 2917 package format.

The Panasonic part offers the following advantages:

• Active product status ensures long-term availability and supply chain continuity
• Lower ESR (3 mOhm versus 9 mOhm) provides improved ripple current handling and thermal performance
• Reduced seated height (2.00 mm versus 2.90 mm) offers improved PCB layout flexibility
• ROHS3 compliance and REACH unaffected status maintain regulatory alignment

Both components are rated for identical operating temperature ranges (-55°C to 105°C) and lifetime specifications (2000 Hrs @ 105°C), confirming functional equivalence for general purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic EEF-GX0D471R be used as a direct replacement for the Rubycon 2SW470M2.9X7.3?

A: Yes. Both components share identical capacitance (470 µF), voltage rating (2 V), tolerance (±20%), package type (2917 Metric), and operating specifications. The Panasonic part is electrically and mechanically compatible for direct substitution.

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

A: The Panasonic EEF-GX0D471R has lower ESR (3 mOhm) compared to the Rubycon 2SW470M2.9X7.3 (9 mOhm). Lower ESR reduces heat generation under ripple current conditions and improves transient response characteristics. This represents an improvement in performance.

Q: Are there any PCB layout considerations when substituting these parts?

A: The Panasonic EEF-GX0D471R has a maximum seated height of 2.00 mm, compared to 2.90 mm for the Rubycon part. This 0.90 mm height reduction may provide additional clearance in space-constrained applications. Both components use identical land pattern dimensions (7.30 mm × 4.30 mm), so PCB footprints remain unchanged.

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

A: This designation indicates the Rubycon 2SW470M2.9X7.3 has been discontinued or superseded by the manufacturer. The Panasonic EEF-GX0D471R, with Active product status, is the recommended alternative for new designs and ongoing production requirements.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the Rubycon 2SW470M2.9X7.3 and Panasonic EEF-GX0D471R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
