2SW220M Equivalent & Substitute Parts

Part Overview

The 2SW220M is a 220 µF, 2 V aluminum polymer capacitor manufactured by Rubycon in the 2917 (7343 Metric) surface mount package. This component is designed for general purpose applications requiring low ESR and stable performance across extended temperature ranges. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SW220M is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 220 µF (exact match required)
• Voltage Rating: 2 V (exact match required)
• Tolerance: ±20% (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 circuit performance)
• Lifetime @ Temperature: 2000 Hrs @ 105°C (exact match required for reliability specifications)
• Operating Temperature Range: -55°C to 105°C (exact match required)

The EEF-SX0D221ER from Panasonic Electronic Components meets all substitution criteria and is classified as an equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0D221ER is a direct equivalent for the obsolete 2SW220M. Both components meet identical electrical specifications and are housed in the same 2917 (7343 Metric) package with identical land pattern dimensions. The EEF-SX0D221ER carries Active product status and maintains full ROHS3 compliance, making it suitable for new designs and production continuity. The lower seated height (2.00 mm versus 2.70 mm) and higher ripple current capability (6.3 A versus 4.6 A @ 100 kHz) of the Panasonic part provide additional design margin without compromising compatibility.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0D221ER be used as a direct replacement for the 2SW220M on existing PCBs?

A: Yes. Both parts share identical electrical specifications (220 µF, 2 V, ±20%, 9 mOhm ESR, 2000 Hrs @ 105°C) and the same 2917 (7343 Metric) package with matching land pattern dimensions (0.287" L x 0.169" W). No PCB modifications are required.

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

A: The EEF-SX0D221ER has a maximum seated height of 2.00 mm compared to 2.70 mm for the 2SW220M. This lower profile may provide additional clearance in space-constrained applications but does not affect electrical compatibility.

Q: Are there compliance differences between the two parts?

A: Both parts are ROHS3 compliant and REACH unaffected. The EEF-SX0D221ER carries Active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete 2SW220M.

Q: Does the higher ripple current rating of the EEF-SX0D221ER affect substitution suitability?

A: No. The higher ripple current capability (6.3 A versus 4.6 A @ 100 kHz) of the Panasonic part is a performance advantage that does not compromise compatibility. The part will operate within all specified parameters of the original design.

Q: What packaging options are available for the EEF-SX0D221ER?

A: The EEF-SX0D221ER is supplied in Tape & Reel (TR) packaging, standard for high-volume surface mount assembly operations.
