Substitute Part Grouping Explanation

Substitution of the EEF-SX0E331E4 is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 330 µF (exact match required)
• Voltage Rating: 2.5 V (exact match required)
• Dielectric Type: Aluminum Polymer (exact match required)
• ESR: 4.5 mOhm (exact match required)
• Thermal Lifetime: 2000 Hrs @ 105°C (exact match required)
• Package / Case: 2917 (7343 Metric) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Temperature Range: -55°C to 105°C (exact match required)

The EEF-LX0E331R4 meets all substitution criteria as a parametric equivalent. Both parts share identical electrical performance, thermal characteristics, and physical dimensions. The primary difference is the series designation (SX versus LX) and packaging format (standard versus Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

Both the EEF-SX0E331E4 and EEF-LX0E331R4 are active production parts with full RoHS3 compliance and REACH unaffected status, making them suitable for regulated applications. Selection between these parts should be based on packaging and supply chain requirements:

• EEF-SX0E331E4: Use when standard packaging is required or when inventory management favors individual unit handling.
• EEF-LX0E331R4: Use when Tape & Reel packaging is preferred for automated assembly processes or high-volume production environments.

Both parts deliver identical electrical performance, thermal stability, and mechanical compatibility. The choice between series designations (SX versus LX) does not affect functional performance in the application circuit.

Frequently Asked Questions (FAQ)

Q: Can EEF-LX0E331R4 be used as a direct replacement for EEF-SX0E331E4?

A: Yes. Both parts are parametric equivalents with identical capacitance, voltage rating, ESR, thermal lifetime, operating temperature range, and physical dimensions. The primary difference is packaging format (Tape & Reel versus standard).

Q: Are there any electrical performance differences between these parts?

A: No. Both parts share identical specifications for capacitance (330 µF), voltage rating (2.5 V), ESR (4.5 mOhm), ripple current capability (8.5 A @ 100 kHz), and thermal lifetime (2000 Hrs @ 105°C).

Q: Do both parts fit the same PCB footprint?

A: Yes. Both parts use the 2917 (7343 Metric) package with identical dimensions of 7.30mm length × 4.30mm width and 2.00mm maximum seated height. PCB land patterns are identical.

Q: What is the difference between SP-Cap SX and SP-Cap LX series?

A: The series designation reflects internal product line organization within Panasonic's aluminum polymer capacitor portfolio. Both series meet identical electrical and mechanical specifications for this part number. The functional performance in circuit applications is equivalent.

Q: Are both parts compliant with environmental regulations?

A: Yes. Both EEF-SX0E331E4 and EEF-LX0E331R4 are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: Which packaging format should I select for my application?

A: Select Tape & Reel (EEF-LX0E331R4) for automated assembly and high-volume production. Select standard packaging (EEF-SX0E331E4) for manual assembly, prototyping, or applications where individual unit handling is preferred.
