Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2.5SLG180M is determined by strict equivalence across the following parameters:

• Capacitance value: 180 µF (exact match required)
• Voltage rating: 2.5 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: 2917 (7343 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C to 105°C (minimum requirement)
• Lifetime rating: 2000 Hrs @ 105°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

The EEF-SR0E181R from Panasonic Electronic Components meets all substitution criteria and is classified as an active product, providing long-term availability assurance.

Parameter Comparison

Engineering Selection Recommendations

The EEF-SR0E181R is the qualified substitute for the obsolete 2.5SLG180M. Both components meet identical electrical specifications for capacitance, voltage rating, tolerance, and operating temperature range. Both maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

The EEF-SR0E181R offers superior performance characteristics with lower ESR (6 mOhm versus 9 mOhm) and higher ripple current capability (7.5 A versus 2.7 A at 100 kHz). The substitute part is actively manufactured and available in standard tape and reel packaging, ensuring supply chain continuity. The marginal height difference (1.00 mm versus 1.10 mm) is within typical PCB layout tolerances for 2917 package footprints.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SR0E181R be used as a direct replacement for the 2.5SLG180M?

A: Yes. Both parts share identical electrical specifications: 180 µF capacitance, 2.5 V voltage rating, ±20% tolerance, and 2917 (7343 Metric) surface mount package. The substitute meets or exceeds all performance parameters of the original part.

Q: What are the key differences between these two parts?

A: The primary differences are manufacturer (Rubycon versus Panasonic), product status (obsolete versus active), and performance enhancements in the substitute. The EEF-SR0E181R features lower ESR and higher ripple current capability. Height differs by 0.1 mm, which is negligible for standard PCB applications.

Q: Is the packaging difference significant?

A: The original part is supplied in bulk packaging, while the substitute is supplied in tape and reel format. This is a standard production packaging difference with no impact on component functionality or electrical performance.

Q: Are both parts compliant with current regulations?

A: Yes. Both the 2.5SLG180M and EEF-SR0E181R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why should I select the EEF-SR0E181R over the original part?

A: The original part is obsolete and subject to supply discontinuation. The EEF-SR0E181R is an active product with assured long-term availability, superior electrical performance, and equivalent regulatory compliance.
