Equivalent & Substitute Parts for 2SW470MX

Part Overview

The 2SW470MX is a 470 µF, 2 V aluminum polymer capacitor manufactured by Rubycon in the PC-CON and SW series. This surface mount component is housed in a 2917 (7343 Metric) package with a maximum seated height of 2.90 mm and an ESR of 9 mOhm. The part is rated for 2000 hours at 105°C and operates across a temperature range of -55°C to 105°C.

The 2SW470MX carries a "Not For New Designs" product status, indicating that Rubycon has discontinued active development for this component. This status necessitates identification of functionally equivalent alternatives for ongoing production requirements and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the 2SW470MX is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 470 µF (exact match required)
• Voltage Rating: 2 V (exact match required)
• Package Type: 2917 (7343 Metric) (exact match required)
• Mounting Technology: Surface Mount (exact match required)
• Component Type: Aluminum Polymer Capacitor (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match or wider range acceptable)
• Lifetime Rating: 2000 Hrs @ 105°C (exact match or greater acceptable)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The EEF-GX0D471R from Panasonic Electronic Components meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The EEF-GX0D471R is a direct functional equivalent to the 2SW470MX and is the appropriate selection for applications requiring a 470 µF, 2 V aluminum polymer capacitor in a 2917 package.

Product Status Consideration: The 2SW470MX is designated "Not For New Designs," while the EEF-GX0D471R maintains "Active" status. For new design implementations, the EEF-GX0D471R is the recommended choice to ensure long-term component availability and manufacturer support.

Compliance: Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Performance Differential: The EEF-GX0D471R exhibits superior ESR performance at 3 mOhm compared to the 2SW470MX at 9 mOhm, resulting in lower heat dissipation and improved ripple current handling. The EEF-GX0D471R also features a reduced seated height of 2.00 mm versus 2.90 mm, providing additional design flexibility for space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the EEF-GX0D471R be used as a direct replacement for the 2SW470MX in existing designs?

A: Yes. Both components share identical electrical specifications (470 µF, 2 V, ±20% tolerance, 2000 Hrs @ 105°C) and are housed in the same 2917 (7343 Metric) package. The EEF-GX0D471R is footprint-compatible and electrically interchangeable. The reduced height of the EEF-GX0D471R (2.00 mm vs. 2.90 mm) presents no compatibility issues for PCB assembly.

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

A: ESR (Equivalent Series Resistance) directly affects capacitor performance in high-frequency applications. The EEF-GX0D471R's lower ESR of 3 mOhm compared to the 2SW470MX's 9 mOhm results in reduced power dissipation and improved thermal performance. This difference is particularly relevant in applications with significant ripple current or high-frequency switching.

Q: Are both components suitable for new product designs?

A: The EEF-GX0D471R is the appropriate choice for new designs due to its "Active" product status. The 2SW470MX's "Not For New Designs" designation indicates that Rubycon has discontinued active support for this component, making it unsuitable for long-term production commitments.

Q: Do both parts meet current regulatory compliance requirements?

A: Yes. Both the 2SW470MX and EEF-GX0D471R are ROHS3 compliant and REACH unaffected, satisfying current environmental and regulatory standards for electronic component procurement.

Q: Is the package footprint identical between these two parts?

A: Yes. Both components use the 2917 (7343 Metric) package with identical length (7.30 mm) and width (4.30 mm) dimensions. The EEF-GX0D471R has a lower maximum seated height (2.00 mm vs. 2.90 mm), which does not affect PCB footprint compatibility but may provide additional clearance in space-constrained designs.
