Substitute Part Grouping Explanation

Substitution of the Rubycon 4SXE82M is determined by strict equivalence across the following critical parameters:

• Capacitance value: 82 µF (exact match required)
• Voltage rating: 4 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 to 105°C (minimum requirement)
• ESR: 9 mOhm (exact match required)
• Lifetime @ Temperature: 2000 Hrs @ 105°C (minimum requirement)

The Panasonic EEF-SX0G820ER meets all substitution criteria and is classified as an active product, providing long-term availability and supply chain stability.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic EEF-SX0G820ER is a direct functional equivalent to the Rubycon 4SXE82M. Both components are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications.

The primary advantage of selecting the Panasonic substitute is its active product status, ensuring sustained availability and supply chain continuity. The Panasonic part also provides superior ripple current handling (6.3 A versus 3 A at 100 kHz), offering enhanced performance margin in high-frequency applications.

The maximum seated height difference of 0.004" (0.10 mm) between the two parts is within typical PCB design tolerances for surface mount assembly and does not present mechanical compatibility concerns.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic EEF-SX0G820ER be used as a direct replacement for the Rubycon 4SXE82M?

A: Yes. Both parts share identical electrical specifications (82 µF, 4 V, ±20% tolerance, 9 mOhm ESR, 2000 Hrs @ 105°C) and are packaged in the same 2917 (7343 Metric) surface mount case. PCB footprints are compatible.

Q: What is the significance of the ripple current difference?

A: The Panasonic part supports 6.3 A ripple current at 100 kHz compared to 3 A for the Rubycon part. This represents a performance enhancement and does not create compatibility issues. Applications designed for the Rubycon specification will operate within the Panasonic part's rated limits.

Q: Are there any height clearance concerns?

A: The Panasonic part has a maximum seated height of 0.079" (2.00 mm) versus 0.075" (1.90 mm) for the Rubycon part. This 0.004" (0.10 mm) difference is negligible for standard PCB assembly and does not affect component placement or board-level clearances in typical designs.

Q: Why is the Rubycon part classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The Panasonic EEF-SX0G820ER, classified as active, provides equivalent functionality with assured long-term availability.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the Rubycon 4SXE82M and Panasonic EEF-SX0G820ER are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations.
