EEU-FC0J331SB Equivalent & Substitute Parts

Part Overview

The EEU-FC0J331SB is a 330 µF, 6.3 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the FC series. This radial, through-hole component is rated for 1000 hours at 105°C and meets AEC-Q200 automotive standards. The part is currently active in production. Substitute parts may be required due to supply constraints, lead time considerations, or specific application requirements that benefit from alternative performance characteristics such as extended lifetime ratings or different physical dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FC0J331SB is determined by the following core electrical and mechanical parameters:

• Capacitance: 330 µF (exact match required)
• Voltage Rating: 6.3 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Operating Temperature Range: -55°C ~ 105°C (must encompass or equal)
• Ripple Current Ratings: 188.5 mA @ 120 Hz and 290 mA @ 100 kHz (must meet or exceed)

The substitute part UPW0J331MED meets all core electrical parameters. Physical dimensions (lead spacing and height) may vary within acceptable tolerances for through-hole applications. The substitute offers extended lifetime (2000 Hrs @ 105°C) and lower impedance (250 mOhms), providing enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The EEU-FC0J331SB is the preferred selection for new designs due to its active product status and AEC-Q200 automotive qualification. The UPW0J331MED substitute is electrically compatible and meets all core functional requirements. However, the substitute carries an obsolete product status, which may impact long-term availability and supply chain reliability.

Physical dimension differences exist between the two parts: the UPW0J331MED has reduced lead spacing (2.50mm vs. 5.00mm) and lower height (11.00mm vs. 14.70mm). These dimensional variations require PCB layout verification to ensure mechanical compatibility with existing board designs.

The UPW0J331MED offers superior performance through extended lifetime rating (2000 Hrs @ 105°C vs. 1000 Hrs) and lower impedance (250 mOhms vs. 350 mOhms), which may provide benefits in applications requiring enhanced thermal endurance or reduced ESR characteristics.

Frequently Asked Questions (FAQ)

Q: Can UPW0J331MED be used as a direct replacement for EEU-FC0J331SB?

A: Electrical substitution is valid. Both parts share identical capacitance (330 µF), voltage rating (6.3 V), tolerance (±20%), and ripple current specifications. However, physical dimensions differ. Lead spacing is reduced from 5.00mm to 2.50mm, and height is reduced from 14.70mm to 11.00mm. PCB layout compatibility must be verified before implementation.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer (Panasonic vs. Nichicon), product status (active vs. obsolete), lifetime rating (1000 Hrs vs. 2000 Hrs @ 105°C), impedance (350 mOhms vs. 250 mOhms), and physical dimensions. Electrical performance and temperature range are equivalent.

Q: Is the substitute part suitable for automotive applications?

A: The main part EEU-FC0J331SB carries AEC-Q200 automotive qualification. The substitute UPW0J331MED does not list automotive ratings. Application suitability depends on specific automotive qualification requirements for the end product.

Q: What impact do the dimensional differences have on board design?

A: The reduced lead spacing (2.50mm vs. 5.00mm) and lower height (11.00mm vs. 14.70mm) of the substitute require PCB footprint modification. Existing through-hole pad patterns designed for the main part may not accommodate the substitute without layout revision.

Q: Why is the substitute part listed as obsolete?

A: Obsolete status indicates the UPW0J331MED is no longer in active production. While existing inventory may be available, future procurement cannot be guaranteed. The active status of EEU-FC0J331SB provides superior long-term supply chain assurance.
