Engineering Selection Recommendations

For Direct Replacement (Same Specifications): Select 860020378021 (Würth Elektronik WCAP-ATG5) when the original 860010378021 is unavailable. Both maintain 2200 µF capacitance and 16 V rating with identical package dimensions. The ATG5 series extends operating temperature to 105°C and lifetime to 2000 Hrs @ 105°C, providing improved thermal margin without design modification.

For Extended Lifetime Applications: The 860160378038 (Würth Elektronik WCAP-ATLL) offers 7000 Hrs @ 105°C lifetime, suitable for applications requiring extended operational duration. Operating temperature range extends to -55°C, accommodating wider environmental conditions. Physical footprint remains identical to the main part.

For Active Product Status Requirement: When new design qualification is mandatory, select from Active-status parts: 860020378021, 860160378038, UPA1C222MHD1TO, ECA-1CHG222B, EEU-FR1C222B, EEU-HD1E222B, or 25PK2200MEFCG412.5X20. Parts marked "Not For New Designs" (UFW1C222MHD1TO, UKW1C222MHD1TO, UVR1C222MHD1TO) are suitable only for legacy system maintenance.

For Voltage Margin Enhancement: EEU-HD1E222B and 25PK2200MEFCG412.5X20 provide 25 V rating with identical 2200 µF capacitance. These are applicable when circuit design permits higher voltage rating and additional safety margin is required.

For RoHS3 Compliance: All listed substitutes maintain ROHS3 compliance. EEU-HD1E222B specifies MSL 1 (Unlimited), providing superior moisture handling compared to the main part's Not Applicable rating.

Frequently Asked Questions (FAQ)

Q: Can I substitute 860010378021 with a part rated at 25 V instead of 16 V?

A: Yes. Parts EEU-HD1E222B and 25PK2200MEFCG412.5X20 are electrically compatible substitutes with 25 V rating. Higher voltage rating does not degrade performance in 16 V circuits; it provides additional voltage margin. Physical package dimensions remain within acceptable tolerance for through-hole mounting with 5.00 mm lead spacing.

Q: What is the difference between parts marked "Active" and "Not For New Designs"?

A: "Active" status indicates the manufacturer continues production and supports new design qualification. "Not For New Designs" indicates the manufacturer has discontinued active support, though existing inventory remains available for legacy system maintenance. For new circuit designs, select only Active-status parts.

Q: Are Nichicon and Panasonic substitutes mechanically compatible with the Würth Elektronik original?

A: Yes, with minor dimensional variation. Nichicon and Panasonic parts maintain 0.197" (5.00 mm) lead spacing and radial can package. Physical diameter varies slightly (0.492" vs. 0.512"), and height differs marginally (0.866" vs. 0.846"). These variations remain within standard PCB through-hole tolerance and do not affect electrical performance or mechanical mounting.

Q: Which substitute offers the longest operational lifetime?

A: EEU-FR1C222B (Panasonic FR-A series) provides 10000 Hrs @ 105°C, the highest lifetime rating among all listed substitutes. This part is suitable for applications requiring extended service intervals and reduced maintenance frequency.

Q: Can I use UPA1C222MHD1TO as a direct replacement in existing assemblies?

A: Yes. UPA1C222MHD1TO maintains 2200 µF capacitance, 16 V rating, and ±20% tolerance. Operating temperature extends to -55°C, and lifetime reaches 5000 Hrs @ 105°C. Physical dimensions differ slightly (0.492" diameter, 0.866" height vs. 0.512" diameter, 0.846" height), but lead spacing remains 5.00 mm, compatible with existing PCB layouts.

Q: What compliance certifications apply to all substitute parts?

A: All listed substitutes maintain ROHS3 compliance and EAR99 export classification. REACH status varies: most parts are REACH Unaffected; UPA1C222MHD1TO is REACH Affected. Verify REACH compliance requirements for your specific application and destination market before final selection.
