Substitute Part Grouping Explanation

Substitution of the Rubycon 6SW220M is determined by strict equivalence across the following parameters:

• Capacitance value: 220 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package: 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)
• Type: Aluminum Polymer (exact match required)

The Panasonic EEF-CX0J221R meets all substitution criteria. Variations in ESR, ripple current capability, and physical height do not disqualify a part from substitution when all primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic EEF-CX0J221R is a direct functional equivalent to the Rubycon 6SW220M. Both components share identical electrical specifications for capacitance, voltage rating, tolerance, and operating temperature range. Both are ROHS3 compliant and maintain the same 2000-hour lifetime rating at 105°C.

The Panasonic part is currently in active production status, ensuring availability for new designs and production runs. The Rubycon 6SW220M, classified as obsolete, presents supply chain risk for ongoing applications.

Physical compatibility is maintained through identical package designation (2917 / 7343 Metric) and surface mount land size. The Panasonic part features a reduced seated height (1.90 mm versus 2.90 mm), which provides additional clearance margin in space-constrained designs without compromising electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic EEF-CX0J221R be used as a direct replacement for the Rubycon 6SW220M?

A: Yes. Both components meet identical specifications for capacitance (220 µF), voltage rating (6.3 V), tolerance (±20%), package (2917 / 7343 Metric), and operating temperature range (-55°C to 105°C). PCB layout and assembly processes require no modification.

Q: What is the significance of the ESR difference between the two parts?

A: The Rubycon part specifies 9 mOhm ESR while the Panasonic part specifies 15 mOhm ESR. Both values fall within acceptable ranges for general purpose aluminum polymer capacitor applications. ESR differences do not affect substitution eligibility when primary electrical parameters are equivalent.

Q: Does the height difference affect PCB compatibility?

A: No. The Panasonic part is physically shorter (1.90 mm seated height versus 2.90 mm). This reduction in height provides additional clearance and does not create compatibility issues. The identical land size (7.30 mm × 4.30 mm) ensures proper mounting on existing PCB layouts.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the Rubycon 6SW220M and Panasonic EEF-CX0J221R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why is the Rubycon part classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Panasonic EEF-CX0J221R, classified as active, represents the current production equivalent for this capacitance and voltage rating in the 2917 package.
