EEU-FC0J682S Equivalent & Substitute Parts

Part Overview

The EEU-FC0J682S is a 6800 µF, 6.3 V aluminum electrolytic capacitor in radial, can package manufactured by Panasonic Electronic Components. This component is rated for automotive applications under AEC-Q200 with a 5000-hour lifetime at 105°C operating temperature. The part is currently active in production. Substitute parts may be required due to inventory constraints, design revisions, or application-specific performance requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: capacitance value (6800 µF), rated voltage (6.3 V), tolerance (±20%), lead spacing (0.295" / 7.50 mm), package type (radial, can), mounting type (through hole), and polarization (polar). All identified substitutes meet these core electrical and mechanical requirements. Physical dimensions (diameter and height) may vary within acceptable limits for through-hole mounting. Lifetime ratings and ripple current specifications are provided for reference but do not restrict substitution eligibility. Product status and application classification are noted for design consideration.

Engineering Selection Recommendations

EEU-FC0J682S and EEU-FC0J682 are both Panasonic components with active product status and AEC-Q200 automotive rating. These parts are preferred for new designs requiring automotive-grade qualification. Both meet ROHS3 compliance requirements.

UPJ0J682MHD and UPW0J682MHD are Nichicon equivalents with "Not For New Designs" status. These parts are electrically and mechanically compatible but are designated for legacy or existing design support only. UPW0J682MHD offers extended lifetime (8000 hours at 105°C) compared to the 5000-hour rating of the main part.

Physical dimension variations exist across the substitute group. EEU-FC0J682S has the largest diameter (18.00 mm) and shortest height (20.00 mm). EEU-FC0J682, UPJ0J682MHD, and UPW0J682MHD share a smaller diameter (16.00 mm) with varying heights. PCB layout and mechanical clearance must be verified before substitution.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC0J682 be used as a direct replacement for EEU-FC0J682S?

A: Yes. Both parts share identical electrical specifications: 6800 µF capacitance, 6.3 V rated voltage, ±20% tolerance, and -55°C to 105°C operating range. Both are Panasonic FC series with active product status and AEC-Q200 rating. Physical dimensions differ; verify PCB layout compatibility before substitution.

Q: Are Nichicon UPJ0J682MHD and UPW0J682MHD suitable for new automotive designs?

A: Both Nichicon parts carry "Not For New Designs" status. They are electrically and mechanically equivalent but are restricted to legacy design support and existing production. New automotive designs should use active-status parts: EEU-FC0J682S or EEU-FC0J682.

Q: What is the difference between UPJ0J682MHD and UPW0J682MHD?

A: Both are Nichicon 6800 µF, 6.3 V radial capacitors with identical electrical parameters and physical dimensions. UPW0J682MHD offers extended lifetime: 8000 hours at 105°C versus 5000 hours for UPJ0J682MHD. Ripple current specifications also differ slightly between the two series.

Q: Do all substitute parts fit the same PCB footprint?

A: No. Lead spacing is identical (0.295" / 7.50 mm) across all parts, but can diameter and height vary. EEU-FC0J682S: 18.00 mm diameter, 20.00 mm height. EEU-FC0J682, UPW0J682MHD: 16.00 mm diameter, 25.00 mm height. UPJ0J682MHD: 16.00 mm diameter, 33.00 mm height. Verify mechanical clearance in your specific application.

Q: Are all parts RoHS3 compliant?

A: Yes. All four parts listed carry ROHS3 Compliant status and are suitable for applications requiring RoHS compliance.
