Engineering Selection Recommendations

For Active Product Status Applications:

The 860020678026 (Würth Elektronik WCAP-ATG5) provides a direct upgrade path from the 860010678024, maintaining identical physical dimensions while extending the operating temperature range to -40°C ~ 105°C and improving thermal performance to 2000 hours at 105°C. Both parts are Active status and ROHS3 compliant.

The ECA-1HM102B (Panasonic M-A series) is an Active status alternative with identical thermal specifications to the main part. Physical dimensions differ slightly (0.492" diameter vs. 0.512"), but lead spacing and mounting type remain compatible. High inventory availability supports production continuity.

The ECA-1HHG102B (Panasonic NHG-A series) and EEU-HD1H102B (Panasonic HD series) are Active status upgrade options offering extended operating temperature ranges (-55°C ~ 105°C) and improved thermal performance (2000 Hrs @ 105°C). Both are suitable for applications requiring enhanced thermal reliability.

For Legacy or Constrained Applications:

The Nichicon UFW1H102MHD1TO, UKW1H102MHD1TO, UVK1H102MHD1TO, and UVR1H102MHD1TO series are classified as Not For New Designs. These parts maintain identical electrical and thermal specifications to the main part but should not be selected for new product development. Existing designs using these parts may continue with current inventory.

All substitute parts maintain ROHS3 compliance and are suitable for through-hole mounting applications with 5.00 mm lead spacing.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 860010678024 with any of the listed parts?

A: Substitution depends on application requirements. All listed parts share identical capacitance (1000 µF), voltage rating (50 V), tolerance (±20%), and lead spacing (5.00 mm). Direct substitutes maintain the same thermal specifications (2000 Hrs @ 85°C). Upgrade substitutes offer extended temperature ranges and improved thermal performance (2000 Hrs @ 105°C). Parts marked "Not For New Designs" are available but not recommended for new product development.

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

A: Direct substitutes (ECA-1HM102B, UFW1H102MHD1TO, UKW1H102MHD1TO, UVK1H102MHD1TO, UVR1H102MHD1TO) maintain identical operating temperature ranges (-40°C ~ 85°C) and lifetime ratings (2000 Hrs @ 85°C). Upgrade substitutes (860020678026, ECA-1HHG102B, EEU-HD1H102B) extend the operating temperature range to -55°C ~ 105°C and improve thermal performance to 2000 Hrs @ 105°C, providing enhanced reliability in high-temperature environments.

Q: Are there physical dimension differences between the main part and substitutes?

A: The main part 860010678024 has a diameter of 0.512" (13.00 mm) and height of 1.043" (26.50 mm). Most substitute parts have a diameter of 0.492" (12.50 mm) and height of 1.063" (27.00 mm). The 860020678026 maintains identical dimensions to the main part. Lead spacing remains constant at 0.197" (5.00 mm) across all parts, ensuring PCB compatibility.

Q: Which substitute should I select for new designs?

A: For new designs, select from parts with Active product status: 860020678026, ECA-1HM102B, ECA-1HHG102B, or EEU-HD1H102B. If thermal performance is critical, the upgrade substitutes (860020678026, ECA-1HHG102B, EEU-HD1H102B) offer extended operating temperature ranges and improved lifetime ratings at elevated temperatures.

Q: Are all substitute parts ROHS3 compliant?

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

Q: What inventory levels are available for each substitute?

A: Inventory varies by part number. The ECA-1HM102B (Panasonic) offers the highest availability at 63,564 pieces. The UVR1H102MHD1TO (Nichicon) provides 16,617 pieces. The 860020678026 (Würth Elektronik) has 2,289 pieces available. Specific inventory should be confirmed at time of procurement.
