Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory and supply chain continuity.

860080472003 (Voltage Upgrade, Same Lifetime): Identical to the main part except for 25 V voltage rating and marginally improved ripple current handling. Suitable for applications requiring higher voltage margin without thermal lifetime extension.

860160372008 (Extended Lifetime, Same Voltage): Maintains 16 V voltage rating while doubling thermal lifetime to 4000 hours at 105°C. Belongs to the WCAP-ATLL series. Recommended for applications requiring extended operational reliability at elevated temperatures.

860160472008 (Extended Lifetime, Voltage Upgrade): Combines 25 V voltage rating with 4000-hour thermal lifetime. Represents the highest specification variant within the substitution group. Suitable for demanding applications requiring both voltage margin and extended service life.

All parts are available in Cut Tape packaging and maintain identical through-hole mounting footprint, ensuring direct PCB compatibility without layout modification.

Frequently Asked Questions (FAQ)

Q: Can 860080472003 replace 860080372002 in a 16 V circuit? A: Yes. The 860080472003 has a 25 V rating, which exceeds the 16 V requirement. Higher voltage ratings provide design margin and do not affect circuit operation at lower voltages.

Q: What is the difference between WCAP-ATLI and WCAP-ATLL series? A: WCAP-ATLI series components have a 2000-hour thermal lifetime at 105°C. WCAP-ATLL series components have a 4000-hour thermal lifetime at 105°C. Both series share identical electrical and physical specifications except for lifetime rating.

Q: Are all substitute parts physically interchangeable? A: Yes. All parts listed maintain identical lead spacing (0.079" / 2.00 mm), case diameter (0.197" / 5.00 mm), and maximum seated height (0.492" / 12.50 mm). Direct board-level substitution is supported without PCB modification.

Q: Can I use 860160472008 in place of 860080372002? A: Yes. The 860160472008 provides both voltage upgrade (25 V vs. 16 V) and extended thermal lifetime (4000 Hrs vs. 2000 Hrs @ 105°C). All physical and mounting characteristics remain identical.

Q: What is the impact of impedance differences between parts? A: Impedance values vary between WCAP-ATLI (380 mOhms for 16 V variant) and WCAP-ATLL (1.24 Ohms for 16 V variant) series. Higher impedance in WCAP-ATLL series reflects internal construction differences that support extended lifetime. Selection should be based on circuit ripple current requirements and thermal operating conditions.

Q: Are all parts ROHS3 compliant? A: Yes. All parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
