Substitute Part Grouping Explanation

Substitution eligibility for the 2.5SLE82M1.4X7.3 is determined by the following critical parameters:

Capacitance Value: Must be 82 µF (±20% tolerance acceptable)
Package / Case: Must be 2917 (7343 Metric) for PCB footprint compatibility
Mounting Type: Must be Surface Mount
Type: Aluminum Polymer construction
Voltage Rating: Must be equal to or greater than 2.5 V
ESR: Must be 9 mOhm or lower
Operating Temperature Range: Must support -55°C to 105°C minimum
Lifetime @ Temperature: Must meet or exceed 2000 Hrs @ 105°C
RoHS Compliance: Must be ROHS3 Compliant

The Panasonic EEF-SX0G820ER qualifies as a direct substitute based on matching capacitance, package, mounting type, ESR, temperature range, lifetime rating, and RoHS compliance. The higher voltage rating (4 V vs. 2.5 V) and increased ripple current capability provide enhanced performance margins without compromising circuit compatibility.

Engineering Selection Recommendations

The Panasonic EEF-SX0G820ER is the qualified substitute for the Rubycon 2.5SLE82M1.4X7.3. Selection is based on the following engineering criteria:

Electrical Compatibility: Both components share identical capacitance (82 µF), tolerance (±20%), ESR (9 mOhm), and thermal lifetime rating (2000 Hrs @ 105°C). The Panasonic part's higher voltage rating (4 V) is electrically compatible with circuits designed for 2.5 V operation and provides additional safety margin.

Physical Compatibility: Both parts use the 2917 (7343 Metric) package with matching footprint dimensions (7.30 mm × 4.30 mm). The Panasonic part has a maximum seated height of 2.00 mm compared to 1.40 mm for the Rubycon part. PCB clearance verification is required to confirm the additional 0.60 mm height does not conflict with adjacent components or enclosure constraints.

Compliance and Support: The Panasonic EEF-SX0G820ER carries Active product status with full ROHS3 compliance and REACH compliance, ensuring continued availability and regulatory support. The original Rubycon part is classified as "Not For New Designs," making the Panasonic substitute the appropriate choice for ongoing production and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can the Panasonic EEF-SX0G820ER directly replace the Rubycon 2.5SLE82M1.4X7.3 on existing PCBs?

A: Yes, the Panasonic part is electrically and mechanically compatible. Both components use the identical 2917 (7343 Metric) package with matching footprint dimensions. However, the Panasonic part is 0.60 mm taller (2.00 mm vs. 1.40 mm seated height). Verify that this height difference does not interfere with adjacent components, solder bridges, or enclosure clearances before implementation.

Q: Why is the Panasonic part rated at 4 V when the original is 2.5 V?

A: The higher voltage rating does not create incompatibility. A 4 V capacitor operates safely in a 2.5 V circuit and provides additional voltage margin, which can improve reliability and reduce stress on the component. The capacitance, tolerance, ESR, and thermal characteristics remain identical, ensuring functional equivalence.

Q: Are there any differences in ripple current handling between these parts?

A: The Panasonic EEF-SX0G820ER supports 6.3 A @ 100 kHz ripple current, compared to 3 A @ 100 kHz for the Rubycon part. This higher ripple current capability in the substitute part is compatible with the original circuit design and does not require circuit modifications.

Q: What is the significance of the product status difference?

A: The Rubycon 2.5SLE82M1.4X7.3 is marked "Not For New Designs," indicating end-of-life status with limited future availability. The Panasonic EEF-SX0G820ER is classified as "Active," ensuring continued manufacturing, supply chain availability, and technical support for both new and legacy applications.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both components are ROHS3 Compliant and REACH Unaffected. Both support the full operating temperature range of -55°C to 105°C and maintain 2000 Hrs lifetime at 105°C. Moisture Sensitivity Level (MSL) for the Rubycon part is rated at 3 (168 Hours), which is standard for this component class.
