Engineering Selection Recommendations

Direct Substitutes (Same Voltage Rating):

860020278023 (Würth Elektronik WCAP-ATG5) is a direct substitute with identical electrical specifications. This part maintains Active product status and extends the maximum operating temperature to 105°C with improved lifetime rating at elevated temperature (2000 Hrs @ 105°C). PCB layout compatibility is maintained due to identical lead spacing and case dimensions.

UFW1A332MHD1TO, UKW1A332MHD1TO, UVK1A332MHD1TO, and UVR1A332MHD1TO (Nichicon series) are direct electrical substitutes but carry "Not For New Designs" product status. These parts feature slightly different case dimensions (0.492" diameter, 0.866" height) compared to the original specification. PCB layout verification is required before implementation.

EEU-FR1A332B (Panasonic FR-A series) is an upgrade substitute with extended lifetime rating (10000 Hrs @ 105°C) and expanded operating temperature range (-40°C ~ 105°C). Active product status and ROHS3 compliance are maintained. Case dimensions differ from the original part (0.492" diameter, 0.866" height).

Upgrade Substitutes (Higher Voltage Rating):

860010378023 (Würth Elektronik WCAP-ATG8) provides voltage upgrade to 16 V while maintaining identical case dimensions and Active product status. This part is suitable for applications requiring increased voltage margin.

EEU-HD1C332B (Panasonic HD series) provides both voltage upgrade to 16 V and extended operating temperature range (-55°C ~ 105°C). Active product status is maintained. Case dimensions differ from the original specification (0.492" diameter, 0.866" height).

Product Status Consideration:

Parts designated "Not For New Designs" (Nichicon UFW, UKW, UVK, UVR series) are acceptable for legacy system maintenance and repair applications only. New product development should prioritize Active status parts: 860020278023, 860010378023, EEU-FR1A332B, or EEU-HD1C332B.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 860010278022 with a 16 V rated capacitor?

A: Yes. The 860010378023 (Würth Elektronik, 16 V) and EEU-HD1C332B (Panasonic, 16 V) are voltage upgrades that maintain all other electrical and mechanical parameters. Higher voltage ratings provide increased design margin without affecting circuit operation at the original 10 V specification.

Q: What is the impact of case dimension differences between substitute parts?

A: The original 860010278022 specifies 0.512" diameter and 0.846" height. Substitute parts from Nichicon (UFW, UKW, UVK, UVR series) and Panasonic (FR-A, HD series) feature 0.492" diameter and 0.866" height. PCB layout verification is required to confirm that the slightly smaller diameter and greater height accommodate existing footprints and clearance requirements.

Q: Which substitute part offers the longest operational lifetime?

A: The EEU-FR1A332B (Panasonic FR-A series) provides 10000 Hrs @ 105°C lifetime rating, compared to 2000 Hrs @ 85°C for the original part. This represents a five-fold improvement in lifetime specification at a higher operating temperature.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the regulatory requirements of the original 860010278022.

Q: Can I use Nichicon parts marked "Not For New Designs" in new product development?

A: No. Parts designated "Not For New Designs" are restricted to legacy system maintenance and repair applications. New product development must utilize Active status parts: 860020278023, 860010378023, EEU-FR1A332B, or EEU-HD1C332B.

Q: What is the difference between direct substitutes and upgrade substitutes?

A: Direct substitutes (860020278023, Nichicon series, EEU-FR1A332B) maintain the original 10 V voltage rating. Upgrade substitutes (860010378023, EEU-HD1C332B) provide higher voltage ratings (16 V) for applications requiring increased voltage margin. Both categories maintain identical capacitance, tolerance, and lead spacing specifications.
