Engineering Selection Recommendations

Primary Substitute (Upgrade): Würth Elektronik 860160378038 (WCAP-ATLL series) is the recommended upgrade substitute. It maintains identical electrical specifications and lead spacing while offering extended lifetime of 7000 hours at 105°C and expanded operating temperature range (-55°C to 105°C). Both parts are Active status and ROHS3 compliant.

Extended Lifetime Alternative: Panasonic EEU-FR1C222B (FR-A series) provides the highest rated lifetime of 10000 hours at 105°C with Active product status and ROHS3 compliance. Physical dimensions differ slightly (0.492" diameter vs. 0.512" for the main part), requiring PCB layout verification.

Direct Equivalent (Same Manufacturer): Panasonic ECA-1CHG222B (NHG-A series) matches the 2000-hour lifetime specification with Active status and ROHS3 compliance. Physical dimensions are 0.492" diameter and 0.866" height.

Nichicon Alternatives: UPA1C222MHD1TO (UPA series) offers 5000-hour lifetime with Active status. UKA1C222MHD1TO (UKA series) is marked as Not For New Designs and should not be selected for new circuit implementations.

Higher Voltage Option: Panasonic EEU-HD1E222B (HD series) is rated at 25 V instead of 16 V. This part is electrically compatible for 16 V applications but introduces a voltage derating margin. Selection requires confirmation that the higher voltage rating does not conflict with circuit design constraints.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Würth Elektronik 860020378021 with any of the listed parts?

A: Substitution is valid only for parts that maintain the mandatory parameters: 2200 µF capacitance, 16 V voltage rating, ±20% tolerance, radial can package, 0.197" (5.00 mm) lead spacing, and through-hole mounting. The EEU-HD1E222B operates at 25 V and is suitable only if your circuit design permits higher voltage rating. The UKA1C222MHD1TO is marked Not For New Designs and should not be used in new applications.

Q: What is the difference between the main part and the Würth Elektronik 860160378038 upgrade?

A: Both parts are manufactured by Würth Elektronik with identical electrical ratings and lead spacing. The 860160378038 (WCAP-ATLL series) extends the rated lifetime from 2000 hours to 7000 hours at 105°C and expands the operating temperature range to -55°C to 105°C. Physical dimensions remain compatible.

Q: Do the substitute parts fit the same PCB footprint?

A: All substitute parts share the same 0.197" (5.00 mm) lead spacing, ensuring compatibility with existing through-hole PCB layouts. However, physical diameter and height vary: the main part and Würth 860160378038 are 0.512" diameter and 0.846" height, while Nichicon UPA1C222MHD1TO, Panasonic ECA-1CHG222B, and EEU-FR1C222B are 0.492" diameter and 0.866" height. Verify clearance in your specific PCB layout before substitution.

Q: Which substitute offers the longest operational lifetime?

A: The Panasonic EEU-FR1C222B (FR-A series) is rated for 10000 hours at 105°C, the highest among all listed parts. The Würth Elektronik 860160378038 provides 7000 hours, and the Nichicon UPA1C222MHD1TO provides 5000 hours.

Q: Is the EEU-HD1E222B a direct substitute?

A: The EEU-HD1E222B is electrically compatible for 16 V applications but is rated at 25 V. It functions as a substitute with voltage derating. Confirm that your circuit design does not require the 16 V rating as a hard constraint before selection.

Q: What is the compliance status of these parts?

A: All listed parts are ROHS3 compliant. The Nichicon UPA1C222MHD1TO is REACH Affected; all other parts are REACH Unaffected. All parts carry EAR99 ECCN classification.
