Engineering Selection Recommendations

Direct Equivalent (Preferred): EEU-FC2A680 is the parametric equivalent to EEU-FC2A680Y, both manufactured by Panasonic with identical electrical specifications, lifetime rating, and physical dimensions. Both parts are active and ROHS3 compliant.

Panasonic Alternatives: EEU-FC2A680L and EEU-FC2A680LB are Panasonic alternatives with reduced lifetime rating (3000 Hrs @ 105°C versus 5000 Hrs). These parts are suitable for applications where extended thermal life is not a design requirement. EEU-FC2A680LB is available in Cut Tape packaging format. Both maintain ROHS3 compliance and AEC-Q200 automotive qualification.

Nichicon Alternatives: UPJ2A680MHD6, UPM2A680MHD6, UPM2A680MPD, and UPW2A680MPD are Nichicon-manufactured substitutes. All four parts maintain 5000-hour lifetime rating and ROHS3 compliance. UPM2A680MHD6 and UPM2A680MPD carry AEC-Q200 automotive qualification. Parts designated "Not For New Designs" are available for existing design support and replacement applications. UPM2A680MPD and UPW2A680MPD feature reduced can diameter (0.394" versus 0.492") with increased height, requiring PCB layout verification for mechanical fit.

Compliance Considerations: UPM2A680MHD6 and UPM2A680MPD carry REACH Affected status, requiring verification against specific application regulatory requirements. UPW2A680MPD and UPJ2A680MHD6 are REACH Unaffected.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC2A680L be used as a direct replacement for EEU-FC2A680Y? A: EEU-FC2A680L is electrically compatible but has a reduced lifetime rating of 3000 hours at 105°C compared to 5000 hours for EEU-FC2A680Y. Substitution is permissible only if the application does not require the extended thermal life specification. Physical dimensions also differ: EEU-FC2A680L has a smaller diameter (0.394" versus 0.492") and greater height (0.984" versus 0.630"), requiring PCB layout verification.

Q: What is the difference between Panasonic FC series and Nichicon UPM/UPJ/UPW series? A: Both manufacturers produce 68 µF, 100 V aluminum electrolytic capacitors with identical electrical ratings and lead spacing. Panasonic FC series parts are currently active. Nichicon UPM, UPJ, and UPW series are designated "Not For New Designs" but remain available for existing applications. Selection depends on supply availability, design phase (new versus legacy), and specific compliance requirements.

Q: Are there physical size constraints when substituting between parts? A: Yes. EEU-FC2A680Y has a can diameter of 0.492" and height of 0.630". Panasonic EEU-FC2A680L and Nichicon UPM2A680MPD and UPW2A680MPD have smaller diameters (0.394") but greater heights (0.984" to 1.063"). Verify PCB layout and component clearances before substitution. EEU-FC2A680 and Nichicon UPJ2A680MHD6 and UPM2A680MHD6 maintain the same 0.492" diameter as the original part.

Q: Which substitute part has the lowest impedance? A: EEU-FC2A680L and UPM2A680MPD both feature 210 mOhms impedance, compared to 230 mOhms for EEU-FC2A680Y. UPW2A680MPD has the highest impedance at 300 mOhms. Lower impedance may provide improved ripple current performance in high-frequency applications.

Q: Can Nichicon parts with "Not For New Designs" status be used in new applications? A: Parts designated "Not For New Designs" are available for replacement and support of existing designs. For new product development, Panasonic FC series parts (EEU-FC2A680Y, EEU-FC2A680, EEU-FC2A680L, EEU-FC2A680LB) are recommended as they carry active product status.

Q: What is the difference between Bulk and Cut Tape packaging? A: Bulk packaging is supplied as loose components suitable for manual assembly or tube feeding. Cut Tape (CT) packaging provides components on carrier tape cut to specified lengths, optimized for automated pick-and-place assembly. Electrical specifications are identical; packaging selection depends on assembly process requirements.

Q: Are all substitute parts AEC-Q200 qualified? A: No. Panasonic EEU-FC2A680Y, EEU-FC2A680, EEU-FC2A680L, and EEU-FC2A680LB carry AEC-Q200 automotive qualification. Nichicon UPM2A680MHD6 and UPM2A680MPD are AEC-Q200 qualified. Nichicon UPJ2A680MHD6 and UPW2A680MPD do not carry AEC-Q200 qualification. Verify automotive qualification requirements before substitution in automotive applications.
