Engineering Selection Recommendations

For new design implementations, the 860020778021 (Würth Elektronik, WCAP-ATG5 series) is the preferred substitute. This part maintains Active product status and extends the maximum operating temperature to 105°C while preserving all mandatory electrical and mechanical parameters. Both parts are ROHS3 compliant and REACH unaffected.

The Nichicon alternatives (UFW1J471MHD1TO, UKW1J471MHD1TO, UVR1J471MHD1TD, UVR1J471MHD1TO) are classified as Not For New Designs and should be used only for legacy system maintenance or repair applications where original component sourcing is unavailable. These parts maintain full electrical and mechanical compatibility but carry restricted product status designations.

All substitute parts are ROHS3 compliant with identical HTSUS classification (8532.22.0020) and EAR99 export control status.

Frequently Asked Questions (FAQ)

Q: Can I substitute 860010778020 with 860020778021 in existing designs?

A: Yes. Both parts share identical capacitance (470 µF), voltage rating (63 V), tolerance (±20%), lead spacing (5.00 mm), and package configuration. The 860020778021 offers extended operating temperature capability (-40°C to 105°C versus -40°C to 85°C) and Active product status, making it suitable for direct substitution.

Q: What is the difference between the Würth Elektronik and Nichicon substitute options?

A: The Würth Elektronik 860020778021 maintains Active product status and is approved for new designs. The Nichicon parts (UFW, UKW, UVR series) are classified as Not For New Designs and should be reserved for legacy applications. All parts meet identical electrical specifications and lead spacing requirements.

Q: Are there physical dimension differences between substitute parts?

A: Yes. The Würth Elektronik 860010778020 and 860020778021 have a diameter of 0.512" (13.00 mm) and height of 0.846" (21.50 mm). The Nichicon alternatives have a diameter of 0.492" (12.50 mm) and height of 0.866" (22.00 mm). These dimensional variations remain within standard radial can tolerances and do not affect PCB footprint compatibility for 5.00 mm lead spacing.

Q: Which substitute part has the highest ripple current rating?

A: The 860010778020 (Würth Elektronik, WCAP-ATG8) provides the highest ripple current at high frequency: 1.33584 A @ 100 kHz. The 860020778021 provides 952.2 mA @ 100 kHz. Nichicon parts provide 1.32 A @ 10 kHz (UFW, UKW series) and 1.35 A @ 10 kHz (UVR series). Selection should be based on application ripple current requirements at the specified frequency.

Q: Can I use Nichicon parts in new product designs?

A: No. The Nichicon alternatives (UFW1J471MHD1TO, UKW1J471MHD1TO, UVR1J471MHD1TD, UVR1J471MHD1TO) carry Not For New Designs status. These parts are suitable only for repair, maintenance, or legacy system applications. For new designs, use 860010778020 or 860020778021.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
