Substitute Part Grouping Explanation

Substitution for the EEU-FC2A271L is determined by strict equivalence in the following electrical parameters: capacitance (270 µF), rated voltage (100 V), tolerance (±20%), operating temperature range (-55°C ~ 105°C), and lifetime rating (5000 Hrs @ 105°C). All substitute parts maintain identical electrical specifications and through-hole radial can packaging. Mechanical dimensions and lead spacing may vary within acceptable design tolerances. Packaging format (bulk versus tape & box) does not affect electrical substitutability but may impact procurement and assembly workflows.

Engineering Selection Recommendations

EEU-FC2A271S and EEU-FC2A271SB are direct electrical equivalents with active product status. Both parts are manufactured by Panasonic and maintain identical electrical specifications, operating temperature range, and lifetime ratings. The primary difference is packaging format: EEU-FC2A271S is supplied in bulk, while EEU-FC2A271SB is supplied in tape & box format. Both carry AEC-Q200 automotive ratings and ROHS3 compliance.

UPJ2A271MHD6 is a Nichicon equivalent with identical electrical parameters and ROHS3 compliance. This part is classified as "Not For New Designs," indicating it remains available for existing applications but is not recommended for new product development. The Nichicon part exhibits slightly different mechanical dimensions and lead spacing compared to the Panasonic variants.

For new designs, EEU-FC2A271S or EEU-FC2A271SB are preferred due to active product status and automotive-grade AEC-Q200 certification. For legacy system maintenance where the original EEU-FC2A271L is unavailable, UPJ2A271MHD6 provides electrical equivalence with consideration for mechanical fit verification.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC2A271S replace EEU-FC2A271L directly?

A: Yes. Both parts are electrically identical with 270 µF capacitance, 100 V rating, ±20% tolerance, and 5000 hour lifetime at 105°C. The primary difference is product status: EEU-FC2A271L is obsolete while EEU-FC2A271S is active. Mechanical dimensions differ; verify PCB layout accommodates the larger 18.00mm diameter and 22.00mm height of EEU-FC2A271S versus the 12.50mm diameter and 40.00mm height of the original part.

Q: What is the difference between EEU-FC2A271S and EEU-FC2A271SB?

A: These parts are electrically and mechanically identical. The difference is packaging: EEU-FC2A271S is supplied in bulk packaging, while EEU-FC2A271SB is supplied in tape & box format. Selection depends on procurement and assembly requirements.

Q: Is UPJ2A271MHD6 suitable for automotive applications?

A: UPJ2A271MHD6 meets the same electrical specifications and ROHS3 compliance as the Panasonic alternatives. However, it is classified as "Not For New Designs." For automotive applications requiring AEC-Q200 certification, EEU-FC2A271S or EEU-FC2A271SB are recommended.

Q: What are the mechanical compatibility considerations?

A: The EEU-FC2A271L has a 12.50mm diameter and 40.00mm height with 5.00mm lead spacing. Substitute parts EEU-FC2A271S, EEU-FC2A271SB, and UPJ2A271MHD6 have larger diameters (18.00mm) and shorter heights (22.00mm or 21.50mm) with 7.50mm lead spacing. PCB layout and mechanical clearance must be verified before substitution.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, matching the compliance profile of the original EEU-FC2A271L.
