Substitute Part Grouping Explanation

Substitution eligibility for the 4SW220M is determined by the following critical parameters:

• Capacitance Value: 220 µF (exact match required)
• Voltage Rating: 4 V (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required for PCB compatibility)
• Mounting Type: Surface Mount (exact match required)
• ESR: 9 mOhm (exact match required for electrical performance)
• Lifetime @ Temperature: 2000 Hrs @ 105°C (exact match required for reliability specifications)
• Operating Temperature Range: -55°C ~ 105°C (exact match required)
• Type: Aluminum Polymer (exact match required)
• Tolerance: ±20% (exact match required)

The EEF-SX0G221ER from Panasonic Electronic Components meets all substitution criteria and is classified as an equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0G221ER is a direct equivalent substitute for the 4SW220M. Both components share identical electrical specifications, mechanical dimensions, and compliance certifications. The primary distinction is product status: the 4SW220M is obsolete while the EEF-SX0G221ER remains in active production. The substitute part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Selection of the EEF-SX0G221ER ensures continued availability and compliance for new designs and production runs.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0G221ER be used as a direct replacement for the 4SW220M?

A: Yes. Both parts share identical capacitance (220 µF), voltage rating (4 V), ESR (9 mOhm), package dimensions (2917 / 7343 Metric), and thermal specifications (2000 Hrs @ 105°C). PCB layout and electrical performance remain unchanged.

Q: Are there physical dimension differences between these parts?

A: The seated height differs: 4SW220M is 0.114" (2.90 mm) maximum, while EEF-SX0G221ER is 0.079" (2.00 mm) maximum. Both share identical length (0.287" / 7.30 mm) and width (0.169" / 4.30 mm). Verify clearance in your specific application.

Q: Do both parts meet current compliance standards?

A: Yes. Both the 4SW220M and EEF-SX0G221ER are ROHS3 compliant and REACH unaffected.

Q: What is the ripple current rating difference?

A: The 4SW220M supports 4.6 A @ 100 kHz, while the EEF-SX0G221ER supports 6.3 A @ 100 kHz. The substitute part provides higher ripple current capability.

Q: Why is the 4SW220M listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Rubycon. The EEF-SX0G221ER from Panasonic remains in active production and is the recommended source for new procurement.
