Substitute Part Grouping Explanation

Substitution of the 6SWZ150MR09 is determined by strict equivalence across the following critical parameters:

• Capacitance value: 150 µF (exact match required)
• Voltage rating: 6.3 V (exact match required)
• Capacitor type: Aluminum polymer (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• ESR: 9 mOhm (exact match required)
• Lifetime rating: 2000 Hrs @ 105°C (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)

The substitute part EEF-SX0J151ER from Panasonic Electronic Components meets all these criteria and is therefore a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0J151ER from Panasonic Electronic Components is a direct substitute for the obsolete 6SWZ150MR09. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The Panasonic part carries active product status, ensuring continued availability and supply chain reliability. The maximum seated height difference of 0.004" (0.10mm) between the two parts is within typical PCB design tolerances for surface mount applications and does not affect functional compatibility. Both parts share identical electrical specifications, package dimensions, and thermal ratings, making the EEF-SX0J151ER a suitable replacement for the Rubycon component in general-purpose applications.
