EEU-FC1C332SB Equivalent & Substitute Parts

Part Overview

The EEU-FC1C332SB is a 3300 µF, 16 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the FC series. This radial, through-hole component is rated for 5000 hours at 105°C and meets AEC-Q200 automotive specifications. The part is currently active and available in cut tape packaging with 1292 units in stock.

Substitute parts become necessary when the primary part number reaches end-of-life status, when packaging requirements differ, or when design revisions require alternative manufacturers while maintaining electrical and mechanical compatibility.

Engineering Selection Recommendations

Direct Equivalent (Identical Physical Footprint):

EEU-FC1C332S is the only direct equivalent to EEU-FC1C332SB. Both parts share identical lead spacing (0.295" / 7.50mm), diameter (0.709" / 18.00mm), and electrical specifications. The height difference of 0.079" (2.00mm) between the two Panasonic parts is within typical PCB clearance tolerances. EEU-FC1C332S is active and suitable for new designs.

UPM1C332MHD6 (Nichicon) matches the EEU-FC1C332SB footprint exactly with identical lead spacing, diameter, and height. However, this part carries "Not For New Designs" status and should be used only for legacy system maintenance or repair applications.

Alternative Footprints (Electrical Compatibility Only):

EEU-FC1C332, ELXZ160ELL332MK35S, UPJ1C332MHD, UPM1C332MHD, UPW1C332MHD, and UPW1C332MHD6 all meet the electrical specifications (3300 µF, 16 V, ±20%, polar, through-hole, radial can) but feature different physical dimensions. These parts require PCB layout verification and may not fit existing designs without mechanical modification.

Among alternatives, ELXZ160ELL332MK35S (Chemi-Con) offers extended lifetime (7000 Hrs @ 105°C) and active product status. UPW1C332MHD provides 8000 hours lifetime but with different physical dimensions.

Compliance Considerations:

EEU-FC1C332SB and EEU-FC1C332S are both ROHS3 compliant and AEC-Q200 rated for automotive applications. ELXZ160ELL332MK35S is ROHS3 compliant and active. Nichicon parts (UPJ1C332MHD, UPM1C332MHD, UPM1C332MHD6, UPW1C332MHD, UPW1C332MHD6) carry "Not For New Designs" status and should not be selected for new product development.

Frequently Asked Questions (FAQ)

Q: Can EEU-FC1C332S replace EEU-FC1C332SB directly on the PCB?

A: Yes. EEU-FC1C332S is a direct equivalent with identical lead spacing (0.295" / 7.50mm), diameter (0.709" / 18.00mm), and electrical specifications. The height difference of 0.079" (2.00mm) is within standard PCB clearance tolerances and does not affect functionality or mechanical fit.

Q: What is the difference between cut tape and bulk packaging?

A: EEU-FC1C332SB is supplied in cut tape packaging, while EEU-FC1C332S is supplied in bulk. Both contain the same component. Packaging format affects handling and storage but does not impact electrical or mechanical performance. Tape & Reel packaging is also acceptable for equivalent parts.

Q: Why are some substitute parts marked "Not For New Designs"?

A: Parts marked "Not For New Designs" are legacy components that manufacturers no longer recommend for new product development. These parts may have limited future availability or ongoing support. For new designs, select parts with "Active" product status such as EEU-FC1C332S or ELXZ160ELL332MK35S.

Q: Can I use UPW1C332MHD as a substitute if my PCB layout allows different dimensions?

A: UPW1C332MHD meets all electrical requirements (3300 µF, 16 V, ±20%, polar, through-hole, radial can) and offers extended lifetime (8000 Hrs @ 105°C). However, it has different physical dimensions (0.630" diameter, 0.984" height) compared to the EEU-FC1C332SB (0.709" diameter, 0.866" height). Substitution requires PCB layout verification and mechanical clearance confirmation. Additionally, UPW1C332MHD carries "Not For New Designs" status.

Q: What does AEC-Q200 rating mean?

A: AEC-Q200 is an automotive electronics qualification standard. EEU-FC1C332SB and EEU-FC1C332S both meet this specification, confirming suitability for automotive applications. ELXZ160ELL332MK35S does not list AEC-Q200 rating in the provided data.

Q: Are there any REACH compliance differences between substitutes?

A: EEU-FC1C332SB and UPW1C332MHD are REACH Unaffected. UPM1C332MHD and UPM1C332MHD6 are REACH Affected. This distinction may impact supply chain documentation and regulatory compliance depending on your application region and customer requirements.

Q: Which substitute offers the longest operational lifetime?

A: UPW1C332MHD provides 8000 hours at 105°C, the longest among all listed parts. ELXZ160ELL332MK35S offers 7000 hours at 105°C. The main part EEU-FC1C332SB and most other substitutes are rated for 5000 hours at 105°C. Extended lifetime may be beneficial for high-reliability applications but requires verification of physical fit.
