Key Parameters

Substitute Part Grouping Explanation

Substitution of the EEU-FC1C820B is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value must remain 82 µF
• Tolerance must be ±20%
• Voltage rating must be equal to or greater than 16 V (higher voltage ratings are acceptable in the same circuit application)
• Operating temperature range must encompass -55°C ~ 105°C
• Lifetime specification must meet or exceed 1000 Hrs @ 105°C

Mechanical Compatibility:

• Mounting type must be Through Hole
• Package type must be Radial, Can
• Lead spacing must be 0.197" (5.00mm) to ensure PCB footprint compatibility

Compliance & Certification:

• AEC-Q200 automotive rating must be maintained
• Polarization must remain Polar

The EEU-FC1E820B meets all substitution criteria with an upgraded voltage rating of 25 V, which provides enhanced reliability margin in the same circuit topology.

Parameter Comparison

Engineering Selection Recommendations

The EEU-FC1E820B is the direct substitute for the obsolete EEU-FC1C820B. Both components are manufactured by Panasonic within the FC series and maintain identical electrical specifications for capacitance, tolerance, and operating temperature range. The substitute features a higher voltage rating (25 V vs. 16 V), which is electrically compatible and provides additional design margin without affecting circuit performance.

The EEU-FC1E820B carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. Both parts maintain AEC-Q200 automotive certification and identical mechanical footprints, enabling direct PCB substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the EEU-FC1E820B replace the EEU-FC1C820B in all applications?

A: Yes. The substitute maintains identical capacitance (82 µF), tolerance (±20%), operating temperature range (-55°C ~ 105°C), and lifetime specification (1000 Hrs @ 105°C). The higher voltage rating (25 V) is compatible with circuits designed for 16 V operation and does not introduce functional issues.

Q: Are the physical dimensions identical between the two parts?

A: Lead spacing is identical at 0.197" (5.00mm), ensuring PCB footprint compatibility. The substitute has a slightly larger diameter (0.248" vs. 0.197") and reduced height (0.579" vs. 0.630"), which may require verification in space-constrained layouts.

Q: Does the substitute maintain automotive compliance?

A: Yes. The EEU-FC1E820B carries AEC-Q200 certification identical to the main part, meeting automotive qualification requirements.

Q: What is the difference in ripple current handling?

A: The substitute exhibits higher ripple current capacity at both low frequency (188.5 mA @ 120 Hz vs. 152.8 mA) and high frequency (290 mA @ 100 kHz vs. 235 mA), with improved impedance (350 mOhms vs. 500 mOhms).

Q: Is the packaging format compatible with existing procurement processes?

A: The substitute is supplied in Tape & Box (TB) packaging, whereas the main part packaging format is not specified. Verify packaging compatibility with assembly and storage requirements.
