Substitute Part Grouping Explanation

Substitute parts for the 6SWZ150MR15 are qualified based on the following mandatory electrical and mechanical parameters:

• Capacitance: 150 µF (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -55°C to 105°C (exact match required)
• Type: Aluminum Polymer (exact match required)

Substitute parts may vary in ESR, ripple current capability, and product status. Parts meeting all mandatory parameters above are considered electrically and mechanically compatible for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both Panasonic substitute parts meet all mandatory electrical and mechanical compatibility criteria for direct replacement of the obsolete Rubycon 6SWZ150MR15.

EEF-SX0J151ER is an active product with improved ESR performance (9 mOhm versus 15 mOhm) and higher ripple current capability (6.3 A versus 2.7 A). This part offers enhanced electrical performance characteristics while maintaining identical capacitance, voltage, tolerance, package, and temperature specifications. Active product status ensures long-term availability and supply chain continuity.

EEF-CX0J151R is an active product with ESR and ripple current specifications matching the original part (15 mOhm ESR, 5.1 A ripple current). This part provides direct parametric equivalence to the 6SWZ150MR15 while offering active product status and improved supply availability. The identical ESR rating makes this part suitable for applications with specific impedance requirements.

Both substitute parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements equivalent to the original component.

Frequently Asked Questions (FAQ)

Q: Can EEF-SX0J151ER and EEF-CX0J151R be used interchangeably with the 6SWZ150MR15?

A: Both Panasonic parts meet all mandatory substitution criteria: 150 µF capacitance, 6.3 V voltage rating, ±20% tolerance, 2917 (7343 Metric) package, surface mount configuration, and -55°C to 105°C operating range. They are electrically and mechanically compatible for direct substitution. Differences in ESR and ripple current do not affect compatibility in applications designed for the original part specifications.

Q: What is the difference between EEF-SX0J151ER and EEF-CX0J151R?

A: The primary differences are ESR and ripple current performance. EEF-SX0J151ER provides lower ESR (9 mOhm) and higher ripple current (6.3 A), offering improved electrical performance. EEF-CX0J151R matches the original ESR (15 mOhm) and provides 5.1 A ripple current. Both parts are electrically compatible; selection depends on application requirements and performance preferences.

Q: Are the physical dimensions identical across all three parts?

A: All three parts use the 2917 (7343 Metric) package with identical land size (0.287" L x 0.169" W / 7.30 mm x 4.30 mm). Height specifications are 0.075" (1.90 mm) for the 6SWZ150MR15 and EEF-CX0J151R, and 0.079" (2.00 mm) for EEF-SX0J151ER. These minor height variations remain within typical PCB assembly tolerances and do not affect mounting compatibility.

Q: Why is the original Rubycon part obsolete?

A: Product obsolescence is determined by manufacturer discontinuation. The Panasonic substitute parts are active products, ensuring continued availability for new designs and production requirements.

Q: Do all parts meet the same compliance standards?

A: All three parts are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for electronic component use.
