Engineering Selection Recommendations

Direct Replacement (Panasonic FC Series): EEU-FC2A331S and EEU-FC2A331 are Panasonic FC series parts with active product status. Both maintain identical electrical specifications (330 µF, 100 V, ±20%, 5000 Hrs @ 105°C) and are ROHS3 compliant. EEU-FC2A331S differs only in packaging format (Bulk vs. Cut Tape) and seated height (0.984" vs. 1.063"). EEU-FC2A331 has a smaller diameter (0.630" vs. 0.709") and taller height (1.240"), requiring PCB layout verification before substitution.

Cross-Manufacturer Alternatives (Nichicon): UPM2A331MHD6TN is a Nichicon UPM series part in Cut Tape packaging matching the original packaging format. It maintains identical physical dimensions (0.709" diameter, 1.063" height) and electrical specifications. However, it carries "Not For New Designs" status and REACH Affected compliance, limiting suitability for new applications.

UPJ2A331MHD6 and UPM2A331MHD6 are Nichicon alternatives with matching dimensions and electrical performance but "Not For New Designs" status. UPS2A331MHD has reduced lifetime (3000 Hrs vs. 5000 Hrs) and higher impedance (90 mOhms vs. 70 mOhms). UPW2A331MHD offers extended lifetime (8000 Hrs) but smaller diameter and higher impedance.

Compliance Considerations: EEU-FC2A331SB and EEU-FC2A331S/EEU-FC2A331 maintain AEC-Q200 automotive certification. Nichicon UPM series parts also carry AEC-Q200 rating. UPJ, UPS, and UPW series lack automotive certification. All parts are ROHS3 compliant; however, UPM2A331MHD6 and UPM2A331MHD6TN are REACH Affected.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC2A331S replace EEU-FC2A331SB directly? A: Yes. Both are Panasonic FC series capacitors with identical electrical specifications (330 µF, 100 V, ±20%, 5000 Hrs @ 105°C). The primary difference is packaging format (Bulk vs. Cut Tape) and seated height (0.984" vs. 1.063"). Verify PCB clearance for the 0.079" height difference.

Q: What is the difference between EEU-FC2A331 and EEU-FC2A331SB? A: Both maintain identical electrical specifications and 5000-hour lifetime. EEU-FC2A331 has a smaller diameter (0.630" vs. 0.709") and greater height (1.240" vs. 1.063"). PCB layout compatibility must be verified before substitution due to dimensional differences.

Q: Can Nichicon UPM2A331MHD6TN replace EEU-FC2A331SB? A: Electrical and mechanical specifications are identical. However, UPM2A331MHD6TN carries "Not For New Designs" status and REACH Affected compliance. Use only for legacy system maintenance or when Panasonic parts are unavailable.

Q: Why does UPS2A331MHD have different specifications? A: UPS2A331MHD has reduced lifetime (3000 Hrs vs. 5000 Hrs @ 105°C) and higher impedance (90 mOhms vs. 70 mOhms). It is suitable only for applications with lower thermal stress or where extended lifetime is not required.

Q: Are all substitute parts AEC-Q200 certified? A: No. Panasonic FC series (EEU-FC2A331SB, EEU-FC2A331S, EEU-FC2A331) and Nichicon UPM series (UPM2A331MHD6, UPM2A331MHD6TN) carry AEC-Q200 certification. Nichicon UPJ, UPS, and UPW series do not have automotive certification.

Q: What is the impact of packaging format (Cut Tape vs. Bulk)? A: Packaging format affects handling and assembly processes but does not alter electrical or mechanical performance. Cut Tape (CT) is suitable for automated pick-and-place assembly; Bulk packaging is used for manual assembly or reel-based processes.
