Key Parameters

Substitute Part Grouping Explanation

The EEF-SX0E331ER qualifies as a direct substitute for the EEF-UE0E331CE based on the following matching parameters:

• Capacitance: 330 µF (identical)
• Voltage Rating: 2.5 V (identical)
• Tolerance: ±20% (identical)
• Package / Case: 2917 (7343 Metric) (identical)
• Mounting Type: Surface Mount (identical)
• Type: Aluminum Polymer (identical)

The EEF-SX0E331ER represents an active product line replacement with enhanced specifications including improved ESR (9 mOhm), extended lifetime (2000 Hrs @ 105°C), and wider operating temperature range (-55°C ~ 105°C).

Parameter Comparison

Engineering Selection Recommendations

The EEF-SX0E331ER is the appropriate substitute for the obsolete EEF-UE0E331CE. The substitute part maintains identical electrical specifications (capacitance, voltage, tolerance) and mechanical compatibility (package, footprint, mounting type), ensuring direct PCB-level compatibility.

The EEF-SX0E331ER offers additional advantages: active product status ensures long-term availability, ROHS3 compliance and REACH unaffected status satisfy modern regulatory requirements, and improved performance metrics (lower ESR, extended lifetime, wider temperature range) provide enhanced reliability for new designs.

The reduced seated height (0.079" versus 0.169") of the substitute part may require PCB layout verification to confirm clearance compatibility in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the EEF-SX0E331ER be used as a direct replacement for the EEF-UE0E331CE?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (2.5 V), tolerance (±20%), package (2917 / 7343 Metric), and mounting type (Surface Mount). PCB footprints are compatible.

Q: What is the primary reason for substitution?

A: The EEF-UE0E331CE is obsolete. The EEF-SX0E331ER is an active product from Panasonic Electronic Components that provides equivalent electrical performance with improved specifications and regulatory compliance.

Q: Are there any physical differences between these parts?

A: The seated height differs: EEF-UE0E331CE is 0.169" (4.30mm) maximum, while EEF-SX0E331ER is 0.079" (2.00mm) maximum. The reduced height of the substitute may affect clearance in designs with tight vertical constraints.

Q: Does the substitute part meet current regulatory standards?

A: Yes. The EEF-SX0E331ER is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What are the performance improvements in the substitute part?

A: The EEF-SX0E331ER provides lower ESR (9 mOhm), extended lifetime (2000 Hrs @ 105°C versus 1000 Hrs @ 105°C), and wider operating temperature range (-55°C ~ 105°C versus -40°C ~ 105°C).
