Frequently Asked Questions (FAQ)

Q: Can I use a 35 V rated capacitor in place of the 25 V original part?

A: Yes. A higher voltage rating is a valid upgrade. The 35 V parts (860010572005, 860020572006, 860040572002) maintain identical capacitance and mechanical dimensions while providing additional voltage margin. This is particularly beneficial in applications with voltage transients or marginal supply regulation.

Q: What is the difference between 2.00 mm and 2.50 mm lead spacing?

A: Lead spacing determines the distance between the two radial leads on the PCB. The original 860010472005 uses 2.00 mm spacing. Parts with 2.50 mm spacing (25YXG47MEFCT15X11, UHE1E470MDD1TD) require different PCB hole patterns and cannot be used as direct drop-in replacements without layout modification.

Q: Why should I choose a part with extended lifetime rating?

A: Extended lifetime ratings (5000 hours at 105°C versus 2000 hours at 85°C) indicate improved internal construction and materials. These parts are suitable for applications requiring higher reliability or operation in elevated ambient temperature environments. The WCAP-ATUL series (860040472001, 860040572002) provides 5000-hour ratings.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts listed maintain ROHS3 Compliant status and REACH Unaffected designation, ensuring regulatory compliance for EU and global markets.

Q: What does "Not For New Designs" mean?

A: The Rubycon 25YXG47MEFCT15X11 is marked Not For New Designs, indicating the manufacturer recommends against using this part in new product development. Existing designs may continue using this part, but new applications should select from Active status alternatives.

Q: Can I use an Obsolete part as a substitute?

A: The Nichicon UHE1E470MDD1TD is classified as Obsolete. While it may be available in inventory, obsolete parts carry supply risk and are not recommended for new designs or production quantities. Active status alternatives are preferred.

Q: How do I determine which substitute is best for my application?

A: Selection depends on three factors: (1) Operating temperature environment—if sustained operation above 85°C is required, select parts rated to 105°C; (2) Reliability requirements—if extended service life is critical, select WCAP-ATUL series with 5000-hour ratings; (3) PCB layout constraints—if 2.00 mm lead spacing is required, avoid Rubycon and Nichicon variants. For most applications, 860020472006 (Würth WCAP-ATG5) or 860040472001 (Würth WCAP-ATUL) provide optimal balance of performance and availability.
