Equivalent & Substitute Parts for 6SW220MX

Part Overview

The 6SW220MX is a 220 µF, 6.3 V aluminum polymer capacitor manufactured by Rubycon in the 2917 (7343 Metric) package. This surface mount component is designed for general purpose applications requiring stable capacitance and low equivalent series resistance. The part is classified as "Not For New Designs," indicating that alternative solutions should be evaluated for new development projects. Identifying suitable substitute parts ensures design flexibility and supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the 6SW220MX is determined by the following critical parameters:

Capacitance Value: 220 µF (exact match required)
Voltage Rating: 6.3 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: 2917 (7343 Metric) (exact match required for PCB compatibility)
Mounting Type: Surface Mount (exact match required)
Operating Temperature Range: -55°C to 105°C (minimum requirement)
Lifetime Rating: 2000 Hrs @ 105°C (minimum requirement)
Compliance: ROHS3 Compliant, REACH Unaffected (required for regulatory alignment)

The substitute part EEF-CX0J221R from Panasonic Electronic Components meets all critical electrical and mechanical parameters. Variations in ESR and physical height do not affect functional substitution when the above parameters align.

Engineering Selection Recommendations

The EEF-CX0J221R is a direct functional substitute for the 6SW220MX. Both parts share identical electrical specifications: 220 µF capacitance, 6.3 V voltage rating, ±20% tolerance, and 2000 hour lifetime at 105°C. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary distinction is product status: the 6SW220MX is designated "Not For New Designs," while the EEF-CX0J221R carries "Active" status. For new development projects, the Panasonic part is the appropriate selection. The EEF-CX0J221R exhibits higher ESR (15 mOhm versus 9 mOhm) and reduced seated height (1.90 mm versus 2.90 mm), both of which are acceptable variations for general purpose applications within the specified operating parameters.
