Equivalent & Substitute Parts for 2SW220M2.7X7.3

Part Overview

The Rubycon 2SW220M2.7X7.3 is a 220 µF aluminum polymer capacitor rated at 2 V with a maximum height of 2.70 mm, designed for general purpose applications. This part is classified as "Not For New Designs," indicating it has reached end-of-life status. Finding equivalent substitute parts is necessary for ongoing maintenance, repair, and legacy system support where this capacitor specification remains functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SW220M2.7X7.3 is determined by the following critical parameters:

• Capacitance Value: 220 µF (must match exactly)
• Tolerance: ±20% (must match)
• Package / Case: 2917 (7343 Metric) (must match for PCB compatibility)
• Mounting Type: Surface Mount (must match)
• Operating Temperature Range: -55°C ~ 105°C (must match or exceed)
• Lifetime @ Temperature: 2000 Hrs @ 105°C (must match or exceed)
• Type: Polymer (must match)

The substitute part EEF-CX0J221R meets all critical substitution criteria. While the rated voltage is higher (6.3 V versus 2 V), this represents an upgrade in electrical capability and does not prevent functional substitution in circuits designed for 2 V operation. The substitute part maintains identical capacitance, tolerance, package dimensions, and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic EEF-CX0J221R is a direct functional substitute for the Rubycon 2SW220M2.7X7.3. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute part carries Active product status, ensuring continued availability and supply chain stability compared to the end-of-life Rubycon part.

The EEF-CX0J221R features a lower maximum seated height (1.90 mm versus 2.70 mm), which provides additional clearance margin in space-constrained applications. The higher rated voltage (6.3 V) and slightly elevated ESR (15 mOhm versus 9 mOhm) do not prevent substitution in circuits originally specified for the 2 V, 9 mOhm part, as the substitute operates within the same thermal and temporal performance envelope.

Frequently Asked Questions (FAQ)

Q: Can the EEF-CX0J221R replace the 2SW220M2.7X7.3 in existing designs?

A: Yes. Both parts share identical capacitance (220 µF), tolerance (±20%), package footprint (2917 / 7343 Metric), and thermal lifetime (2000 Hrs @ 105°C). The substitute part's higher voltage rating and lower profile do not prevent functional substitution.

Q: What is the significance of the voltage rating difference?

A: The substitute part is rated for 6.3 V compared to the original 2 V. In circuits operating at or below 2 V, the higher voltage rating of the substitute represents an upgrade in electrical margin and does not create compatibility issues.

Q: Are there physical mounting differences?

A: Both parts use the same 2917 (7343 Metric) package and Surface Mount mounting type. The substitute part has a lower maximum seated height (1.90 mm versus 2.70 mm), which may provide additional PCB clearance in some applications.

Q: Do both parts meet current compliance standards?

A: Yes. Both the original Rubycon part and the Panasonic substitute are ROHS3 compliant and REACH unaffected. The substitute part carries Active product status, ensuring regulatory compliance and supply availability.

Q: What is the ESR difference, and does it matter?

A: The substitute part has an ESR of 15 mOhm compared to the original 9 mOhm. Both values are within acceptable ranges for general purpose aluminum polymer capacitor applications. The difference does not prevent substitution in standard circuit designs.
