Substitute Part Grouping Explanation

Substitution eligibility for the 6SW150M is determined by strict equivalence across the following parameters:

• Capacitance value: 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 for PCB compatibility)
• Mounting type: Surface Mount (exact match required)
• Type: Aluminum Polymer (exact match required)
• Operating temperature range: -55°C ~ 105°C (exact match required)
• ESR: 9 mOhm (exact match required for electrical performance)
• Lifetime @ Temperature: 2000 Hrs @ 105°C (exact match required)

The Panasonic EEF-SX0J151ER meets all substitution criteria and is classified as an active product with improved availability.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic EEF-SX0J151ER is the qualified substitute for the obsolete Rubycon 6SW150M. Both components meet ROHS3 compliance requirements and share identical electrical specifications across all critical parameters: capacitance, voltage rating, tolerance, ESR, lifetime rating, and operating temperature range.

The Panasonic part offers two additional advantages: active product status ensuring continued availability, and a lower seated height (2.00mm versus 2.90mm), which may provide design flexibility in space-constrained applications. The higher ripple current rating (6.3 A versus 4.6 A at 100 kHz) in the Panasonic part represents an enhancement that does not compromise compatibility.

Both components are packaged identically in the 2917 (7343 Metric) case and mount to the same PCB footprint, enabling direct substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic EEF-SX0J151ER replace the Rubycon 6SW150M in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters. The Panasonic part mounts to the identical footprint and delivers the same capacitance, voltage rating, ESR, and lifetime characteristics.

Q: What is the significance of the height difference between these parts?

A: The Panasonic EEF-SX0J151ER has a maximum seated height of 2.00mm compared to 2.90mm for the Rubycon 6SW150M. This difference does not affect electrical performance and may provide additional clearance in designs with height constraints.

Q: Why does the Panasonic part have a higher ripple current rating?

A: The Panasonic EEF-SX0J151ER is rated for 6.3 A ripple current at 100 kHz versus 4.6 A for the Rubycon part. This represents an improvement in thermal performance and does not create compatibility issues. The part remains suitable for all applications designed for the original component.

Q: Are both parts RoHS compliant?

A: Yes. Both the Rubycon 6SW150M and Panasonic EEF-SX0J151ER are ROHS3 compliant.

Q: What packaging options are available for the Panasonic substitute?

A: The Panasonic EEF-SX0J151ER is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.
