Engineering Selection Recommendations

UPW1J331MHD1TO (Nichicon): This part offers extended lifetime (7000 hours at 105°C) compared to the primary part, with improved ripple current handling and lower impedance. Product status is Not For New Designs. ROHS3 compliance is maintained. Selection is appropriate for applications requiring enhanced thermal endurance within the same form factor.

UPS1J331MHD1TD (Nichicon): This part maintains identical electrical and thermal specifications to the primary part (3000 hours at 105°C) with matching ripple current ratings. Product status is Active, indicating ongoing manufacturer support. Packaging format differs (Tape & Box instead of Cut Tape). Selection is appropriate for direct replacement with continued availability assurance.

EEU-FC1J331B (Panasonic Electronic Components): This part provides intermediate lifetime (5000 hours at 105°C) with improved ripple current performance and lower impedance. Product status is Active with AEC-Q200 automotive qualification. ROHS3 compliance is maintained. Selection is appropriate for applications requiring automotive-grade reliability and extended thermal performance.

Frequently Asked Questions (FAQ)

Q: Can UPW1J331MHD1TO be used as a direct replacement for UPS1J331MHD1TO?

A: Yes. Both parts share identical capacitance (330 µF), voltage rating (63 V), tolerance (±20%), operating temperature range (-55°C ~ 105°C), and physical dimensions (0.492" Dia × 0.866" Height, 5.00 mm lead spacing). The UPW1J331MHD1TO offers extended lifetime (7000 hours vs. 3000 hours at 105°C) and improved ripple current specifications, making it a performance upgrade within the same footprint.

Q: What is the difference between Cut Tape and Tape & Box packaging?

A: Cut Tape (CT) packaging provides individual components cut from continuous tape, suitable for automated assembly and smaller order quantities. Tape & Box (TB) packaging provides components on continuous tape within a protective box, typically for larger volume orders. Both formats contain electrically identical components. Selection depends on procurement and assembly process requirements.

Q: Is EEU-FC1J331B suitable for non-automotive applications?

A: Yes. EEU-FC1J331B meets all electrical and mechanical equivalence criteria for the UPS1J331MHD1TO. AEC-Q200 automotive qualification indicates enhanced reliability testing and is not restrictive for general-purpose applications. The part is suitable for any application requiring 330 µF, 63 V aluminum electrolytic capacitors in radial configuration.

Q: Why is UPS1J331MHD1TO marked as Not For New Designs?

A: Product status "Not For New Designs" indicates the manufacturer has superseded this part in their product lifecycle. For new designs, Nichicon recommends UPS1J331MHD1TD (Active status) or UPW1J331MHD1TO as alternatives. Existing designs may continue using UPS1J331MHD1TO subject to inventory availability.

Q: Are all substitute parts ROHS3 compliant?

A: UPW1J331MHD1TO and EEU-FC1J331B are confirmed ROHS3 compliant. UPS1J331MHD1TD compliance status is not specified in the provided data. Verify ROHS3 compliance with the manufacturer if this certification is required for your application.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes, provided the PCB layout accommodates the specified lead spacing (0.197" / 5.00 mm) and component height (0.866" / 22.00 mm). All substitute parts share identical through-hole mounting configuration and physical dimensions. No PCB redesign is required for substitution.
