Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and Active product status, ensuring regulatory alignment with the original component. Selection between substitutes depends on application-specific requirements:

For Direct Replacement (Same Voltage, 10 V): Part 860020272003 provides extended operating temperature range (-40°C to 105°C) and higher temperature lifetime rating (2000 Hrs @ 105°C) while maintaining 10 V voltage specification. This substitution is valid when thermal performance improvement is required without voltage upgrade.

For Voltage Upgrade Applications: Parts 860010372004 (16 V), 860010472005 (25 V), and 860010572005 (35 V) maintain the same series (WCAP-ATG8) and thermal characteristics as the base part while providing higher voltage margins. These are suitable when circuit design requires increased voltage headroom.

For Extended Temperature Range: Parts 860020372004, 860020472006, and 860020572006 (WCAP-ATG5 series) extend the upper operating temperature to 105°C and provide corresponding lifetime ratings at elevated temperature. These are applicable in high-temperature environments.

For Extended Lifetime Applications: Parts 860040472001 and 860040572002 (WCAP-ATUL series) provide 5000 hours lifetime at 105°C, doubling the reliability specification. These are specified for long-life industrial and automotive applications.

For Extended Temperature Range with Low Temperature Capability: Part 860080372001 (WCAP-ATLI series) extends the lower operating temperature to -55°C while maintaining 105°C upper limit, suitable for aerospace and extreme environment applications.

Frequently Asked Questions (FAQ)

Q: Can I substitute 860010272003 with a higher voltage-rated part? A: Yes. Higher voltage ratings (16 V, 25 V, 35 V) are acceptable substitutes provided all other parameters (capacitance, tolerance, physical dimensions, lead spacing, mounting type) remain identical. Higher voltage ratings provide additional safety margin in the circuit.

Q: What is the difference between WCAP-ATG8, WCAP-ATG5, WCAP-ATUL, and WCAP-ATLI series? A: These represent different product lines within Würth Elektronik's aluminum electrolytic capacitor portfolio. WCAP-ATG8 operates to 85°C; WCAP-ATG5 and WCAP-ATLI operate to 105°C; WCAP-ATUL provides extended 5000-hour lifetime at 105°C. Series selection depends on thermal and reliability requirements.

Q: Are all substitute parts through-hole mounted with identical lead spacing? A: Yes. All listed substitutes maintain 0.079" (2.00 mm) lead spacing and through-hole mounting configuration, ensuring direct PCB compatibility without layout modification.

Q: Can I use 860040572002 (35 V, 5000 Hrs @ 105°C) as a direct replacement for 860010272003 (10 V, 2000 Hrs @ 85°C)? A: Yes, from an electrical and mechanical standpoint. The 860040572002 provides higher voltage rating, extended temperature range, and improved lifetime specification. However, verify that the circuit design does not depend on the specific ripple current or impedance characteristics of the original part, as these differ between series.

Q: What does ±20% tolerance mean for the 47 µF capacitance? A: The actual capacitance value will be between 37.6 µF and 56.4 µF. All substitute parts maintain this same tolerance specification, ensuring equivalent performance variation.

Q: Are all parts ROHS3 compliant? A: Yes. All listed substitute parts carry ROHS3 Compliant certification, maintaining regulatory compliance with the original component.

Q: Can I mix different series in the same circuit? A: Mechanically and electrically, yes. All parts share identical physical dimensions and electrical ratings at their specified voltage levels. However, verify that ripple current and impedance specifications align with circuit requirements, as these vary between series.
