Substitute Part Grouping Explanation

Substitution of the 2SW470M 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) surface mount (exact match required)
• Dielectric Type: Aluminum Polymer (exact match required)
• Tolerance: ±20% (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Lifetime Rating: 2000 Hrs @ 105°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The substitute part EEF-SX0D471XE meets all critical substitution criteria. Variations in ESR, ripple current capability, and physical height do not disqualify substitution when all primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0D471XE from Panasonic Electronic Components is a direct functional equivalent to the obsolete 2SW470M. Both components satisfy identical electrical specifications, mechanical footprint requirements, and regulatory compliance standards.

The Panasonic substitute offers measurable performance advantages: lower ESR (6 mOhm versus 9 mOhm) and higher ripple current capability (7.5 A versus 4.6 A at 100 kHz). These improvements enhance thermal performance and reduce voltage ripple in the application circuit. The reduced physical height (2.00 mm versus 2.90 mm) provides additional design flexibility for space-constrained layouts while maintaining identical land pattern compatibility.

Both parts carry ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing and distribution requirements. The Panasonic component is currently in active production with substantial inventory availability, supporting immediate procurement and long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0D471XE be used as a direct replacement for the 2SW470M in existing designs?

A: Yes. Both components share identical capacitance (470 µF), voltage rating (2 V), package type (2917 / 7343 Metric), and land pattern dimensions. The surface mount footprint is fully compatible with no PCB layout modifications required.

Q: What are the differences between these two parts?

A: The primary differences are ESR (6 mOhm versus 9 mOhm), ripple current rating (7.5 A versus 4.6 A at 100 kHz), and physical height (2.00 mm versus 2.90 mm). The Panasonic part delivers superior electrical performance with lower impedance and higher current handling capability.

Q: Does the lower ESR of the substitute part affect circuit operation?

A: Lower ESR is a performance enhancement. It reduces voltage ripple, decreases heat generation, and improves transient response. No circuit redesign is necessary; the substitute performs equal to or better than the original part across all operating conditions.

Q: Are both parts available for procurement?

A: The 2SW470M is obsolete with no ongoing production. The EEF-SX0D471XE is in active production status with substantial inventory availability, ensuring reliable supply for new builds and legacy system support.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations for manufacturing and distribution.

Q: Is the reduced height of the substitute part a concern for PCB assembly?

A: No. The reduced height (2.00 mm versus 2.90 mm) is advantageous for space-constrained designs. The identical land pattern and mounting type ensure standard pick-and-place assembly processes without modification.
