Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FS1J331LB is determined by strict equivalence across the following critical parameters:

• Capacitance value: 330 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage rating: 63 V (exact match required)
• Lifetime specification: 10,000 Hrs @ 105°C (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Lead spacing: 0.197" (5.00 mm) (exact match required)
• Physical dimensions: 0.394" Dia (10.00 mm) (exact match required)
• Compliance: RoHS3 Compliant (exact match required)

The substitute part 63ZLH330MEFCT810X23 from Rubycon meets all critical electrical and mechanical parameters, ensuring direct functional and physical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the EEU-FS1J331LB and 63ZLH330MEFCT810X23 are active products with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability, lead time, and inventory position. The Rubycon 63ZLH330MEFCT810X23 offers equivalent electrical performance and physical compatibility with a seated height 0.5 mm lower than the Panasonic part, which may provide marginal benefits in space-constrained applications. Both parts carry identical ECCN and HTSUS classifications, ensuring consistent regulatory treatment in procurement and logistics.

Frequently Asked Questions (FAQ)

Q: Can the Rubycon 63ZLH330MEFCT810X23 be used as a direct replacement for the Panasonic EEU-FS1J331LB?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (63 V), tolerance (±20%), lifetime specification (10,000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), lead spacing (5.00 mm), and physical diameter (10.00 mm). The parts are functionally and mechanically interchangeable in through-hole applications.

Q: What is the difference in physical height between these two parts?

A: The Panasonic EEU-FS1J331LB has a maximum seated height of 1.004" (25.50 mm), while the Rubycon 63ZLH330MEFCT810X23 has a maximum seated height of 0.984" (25.00 mm). This 0.5 mm difference is within typical PCB layout tolerances and does not affect electrical performance or compatibility.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the EEU-FS1J331LB and 63ZLH330MEFCT810X23 are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by exact equivalence in capacitance (330 µF), voltage rating (63 V), tolerance (±20%), lifetime (10,000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), lead spacing (5.00 mm), physical diameter (10.00 mm), mounting type (through hole), package type (radial can), and compliance certifications (RoHS3).

Q: Can these parts be used in surface-mount applications?

A: No. Both parts are through-hole mounted components with radial lead configurations. They are not suitable for surface-mount applications.
