Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FC0J123L is determined by the following critical parameters:

• Electrical Match: Capacitance (12000 µF), rated voltage (6.3 V), and tolerance (±20%) must be identical
• Thermal Performance: Lifetime rating of 5000 Hrs @ 105°C or greater
• Operating Range: Temperature range must encompass -55°C ~ 105°C
• Mechanical Compatibility: Radial, can package with through-hole mounting
• Certification: AEC-Q200 automotive rating required
• Polarization: Polar configuration

The EEU-FC0J123 meets all substitution criteria. While physical dimensions differ slightly (diameter and height), both components maintain identical electrical specifications, thermal ratings, and automotive certifications, permitting direct functional substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The EEU-FC0J123 is the direct functional equivalent for the obsolete EEU-FC0J123L. Both components share identical electrical specifications, thermal ratings, and automotive certifications. The substitute part offers the additional advantage of active product status and ROHS3 compliance, supporting long-term supply chain continuity.

Physical dimensions differ between the two parts. The EEU-FC0J123 features a larger diameter (0.709" vs. 0.630") but reduced height (1.240" vs. 1.575"). PCB layout verification is required to confirm mechanical fit within the available mounting space. Lead spacing remains identical at 0.295" (7.50mm), ensuring compatibility with existing through-hole footprints.

Frequently Asked Questions (FAQ)

Q: Can the EEU-FC0J123 replace the EEU-FC0J123L in automotive applications?

A: Yes. Both components meet AEC-Q200 automotive standards and share identical electrical specifications (12000 µF, 6.3 V, ±20% tolerance) and thermal performance (5000 Hrs @ 105°C). Mechanical fit must be verified due to dimensional differences.

Q: What are the physical differences between these parts?

A: The EEU-FC0J123 has a larger diameter (18.00mm vs. 16.00mm) and shorter height (31.50mm vs. 40.00mm). Lead spacing is identical at 7.50mm. PCB layout review is necessary to confirm the substitute fits within the available mounting envelope.

Q: Does the EEU-FC0J123 meet RoHS requirements?

A: Yes. The EEU-FC0J123 is ROHS3 compliant, whereas the EEU-FC0J123L is RoHS non-compliant. This represents an improvement in environmental compliance for new designs or production runs.

Q: Are the ripple current ratings equivalent?

A: The ripple current ratings differ slightly between parts. The EEU-FC0J123 provides higher ripple current capacity at both low frequency (3.09 A @ 120 Hz vs. 2.856 A) and high frequency (3.635 A @ 100 kHz vs. 3.36 A). This represents improved performance margin in the substitute component.

Q: What is the impedance difference?

A: The EEU-FC0J123 has slightly higher impedance (16 mOhms vs. 15 mOhms). This minor difference does not affect functional substitution in typical circuit applications.
