Substitute Part Grouping Explanation

Substitution eligibility for the EEU-FC0J682 is determined by strict equivalence in the following parameters:

Capacitance: 6800 µF (exact match required)
Voltage Rating: 6.3 V (exact match required)
Tolerance: ±20% (exact match required)
Package Type: Radial, Can (exact match required)
Mounting Type: Through Hole (exact match required)
Lead Spacing: 0.295" (7.50 mm) (exact match required)
Diameter: 0.630" (16.00 mm) (exact match required)
Operating Temperature Range: -55°C to 105°C (minimum required)
Polarization: Polar (exact match required)
RoHS Compliance: ROHS3 Compliant (minimum required)

Substitute parts are classified into two categories:

Upgrade Substitutes: Parts with improved or equivalent lifetime ratings at 105°C, suitable for direct replacement with potential performance enhancement.

Similar Substitutes: Parts with equivalent electrical characteristics and mechanical compatibility but differing in secondary parameters such as lifetime or impedance specifications.

Engineering Selection Recommendations

UPW0J682MHD (Nichicon): This part qualifies as an upgrade substitute. It maintains all critical electrical and mechanical parameters identical to the EEU-FC0J682 while providing an extended lifetime rating of 8000 hours at 105°C compared to the original 5000 hours. Both parts are ROHS3 compliant. The UPW0J682MHD is marked as "Not For New Designs," indicating it is suitable for replacement applications only.

UPJ0J682MHD (Nichicon): This part qualifies as a similar substitute with equivalent electrical characteristics. It matches the EEU-FC0J682 in capacitance, voltage, tolerance, and operating temperature range. However, the seated height is 1.299" (33.00 mm) compared to 0.984" (25.00 mm) for the original part, and impedance is 29 mOhms versus 22 mOhms. These dimensional and electrical differences require PCB layout verification before implementation. The UPJ0J682MHD is also marked as "Not For New Designs."

Both substitute parts are ROHS3 compliant and maintain the required operating temperature range of -55°C to 105°C.

Frequently Asked Questions (FAQ)

Q: Can UPW0J682MHD be used as a direct replacement for EEU-FC0J682?

A: Yes. The UPW0J682MHD maintains identical capacitance (6800 µF), voltage rating (6.3 V), tolerance (±20%), package type (radial can), lead spacing (0.295" / 7.50 mm), and diameter (0.630" / 16.00 mm). The seated height and impedance are identical. The extended lifetime rating of 8000 hours at 105°C provides improved performance characteristics.

Q: Can UPJ0J682MHD be used as a direct replacement for EEU-FC0J682?

A: Electrical substitution is possible due to matching capacitance, voltage, tolerance, and operating temperature specifications. However, the seated height differs: UPJ0J682MHD is 1.299" (33.00 mm) versus 0.984" (25.00 mm) for the EEU-FC0J682. PCB layout and mechanical clearance must be verified before implementation. Impedance is also higher at 29 mOhms compared to 22 mOhms.

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

A: Substitution requires exact matching of capacitance (6800 µF), voltage rating (6.3 V), tolerance (±20%), package type (radial can), mounting type (through hole), lead spacing (0.295" / 7.50 mm), and diameter (0.630" / 16.00 mm). Operating temperature range must meet or exceed -55°C to 105°C. RoHS compliance status must be ROHS3 or equivalent.

Q: Are both substitute parts suitable for new designs?

A: Both UPW0J682MHD and UPJ0J682MHD are marked as "Not For New Designs." These parts are suitable for replacement and legacy applications only. For new designs, the EEU-FC0J682 (active status) is the recommended selection.

Q: What is the difference in lifetime between the main part and UPW0J682MHD?

A: The EEU-FC0J682 is rated for 5000 hours at 105°C. The UPW0J682MHD is rated for 8000 hours at 105°C, providing a 60% longer operational lifetime under identical thermal conditions.

Q: How do the ripple current ratings compare?

A: At 120 Hz, EEU-FC0J682 is rated for 2.172 A and UPW0J682MHD for 2.176 A (equivalent). At 100 kHz, EEU-FC0J682 is rated for 2.555 A and UPW0J682MHD for 2.56 A (equivalent). UPJ0J682MHD ripple current at 10 kHz is 2.37 A, which is lower than the original part specifications at comparable frequencies.
