Engineering Selection Recommendations

Selection of substitute parts must be based on the following engineering criteria:

Voltage Rating Compatibility: The original part operates at 10 V rated voltage. Substitute parts rated at 10 V maintain direct electrical equivalence. Parts rated at 16 V provide voltage margin and are electrically compatible in circuits designed for 10 V operation, as they accommodate the same or lower voltage stress.

Thermal Performance Requirements: The original part is rated for 2000 hours at 85°C. Substitute parts with extended temperature ranges (-55°C to 105°C versus -40°C to 85°C) and higher lifetime ratings (4000 or 5000 hours at 105°C) provide enhanced thermal stability for applications requiring extended operational life or exposure to elevated ambient temperatures.

Series Designation and Compliance: All substitute parts maintain ROHS3 compliance and Active product status. Series variations (WCAP-ATG8, WCAP-ATG5, WCAP-ATLI, WCAP-ATLL, WCAP-AT1H) represent different thermal and performance grades within the Würth Elektronik aluminum electrolytic capacitor portfolio, each meeting the same dimensional and electrical specifications for the 68 µF, ±20% tolerance category.

Ripple Current Handling: Ripple current specifications vary across substitute parts. Selection should account for circuit ripple current demands at 100 kHz operating frequency. Higher ripple current ratings provide additional margin for high-frequency switching applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute 860010272004 with a 16 V rated part such as 860010372005?

A: Yes. The 16 V rated parts (860010372005, 860020372005, 860080372003, 860160372009) are electrically compatible substitutes. A higher voltage rating does not degrade performance in a 10 V circuit; it provides additional voltage margin and typically improves reliability under transient overvoltage conditions.

Q: What is the difference between WCAP-ATG8, WCAP-ATG5, WCAP-ATLI, WCAP-ATLL, and WCAP-AT1H series?

A: These series designations represent different thermal performance grades. WCAP-ATG8 and WCAP-ATG5 are standard grades with 2000-hour lifetimes. WCAP-ATLI extends the operating temperature range to -55°C. WCAP-ATLL provides 4000-hour lifetime at 105°C. WCAP-AT1H offers 5000-hour lifetime at 105°C. All maintain identical physical dimensions and capacitance values.

Q: Are all substitute parts physically interchangeable?

A: Yes. All listed substitute parts share identical physical dimensions (0.197" diameter, 0.492" height, 0.079" lead spacing), mounting type (Through Hole, Radial, Can), and package configuration. Direct mechanical substitution is possible without PCB layout modification.

Q: Which substitute part should I select for a high-temperature application?

A: For applications requiring extended temperature operation, select parts with expanded operating ranges and higher lifetime ratings. 860160272007 (4000 Hrs @ 105°C, -55°C to 105°C) and 860240272002 (5000 Hrs @ 105°C, -40°C to 105°C) provide enhanced thermal performance compared to the original 860010272004 (2000 Hrs @ 85°C, -40°C to 85°C).

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All substitute parts listed are ROHS3 compliant, REACH unaffected, and classified as Active products. Compliance certifications are consistent across the entire substitute group.

Q: What is the significance of ripple current differences between substitute parts?

A: Ripple current specifications indicate the maximum AC current the capacitor can handle at specified frequencies without exceeding temperature limits. Higher ripple current ratings accommodate circuits with greater high-frequency current demands. Selection should match or exceed the circuit's actual ripple current requirement at 100 kHz.
