Engineering Selection Recommendations

All three parts—860020372005, 860080372003, and 860160372009—are Active status products manufactured by Würth Elektronik and maintain ROHS3 and REACH compliance. Selection between these parts is determined by application-specific requirements:

860020372005 (WCAP-ATG5): Primary specification with 2000-hour lifetime at 105°C and operating temperature range of -40°C to 105°C. Suitable for general-purpose applications within the specified temperature limits.

860080372003 (WCAP-ATLI): Equivalent lifetime rating (2000 hours at 105°C) with extended lower operating temperature limit (-55°C to 105°C). Higher ripple current capability at 100 kHz (230 mA) compared to the main part. Appropriate for applications requiring lower temperature operation.

860160372009 (WCAP-ATLL): Extended lifetime rating of 4000 hours at 105°C with operating temperature range of -55°C to 105°C. Highest ripple current performance at 100 kHz (228 mA). Suitable for long-life applications and extended temperature operation.

Frequently Asked Questions (FAQ)

Q: Can 860080372003 be used as a direct replacement for 860020372005?

A: Yes. Both parts share identical electrical specifications (68 µF, ±20%, 16 V), mechanical dimensions (0.197" Dia, 0.492" height, 0.079" lead spacing), and compliance certifications. The 860080372003 offers extended lower temperature operation (-55°C vs. -40°C) and higher ripple current capability, making it a compatible substitute.

Q: What is the difference between 860160372009 and the other two parts?

A: The 860160372009 provides double the lifetime rating (4000 hours at 105°C versus 2000 hours) and operates across the same extended temperature range as 860080372003 (-55°C to 105°C). All other electrical and mechanical parameters remain identical.

Q: Are all three parts pin-compatible?

A: Yes. All three parts maintain identical lead spacing (0.079" / 2.00 mm), physical diameter (0.197" / 5.00 mm), and height (0.492" / 12.50 mm). They are mechanically interchangeable in through-hole PCB applications.

Q: Do these parts require different PCB footprints?

A: No. The identical mechanical specifications ensure that all three parts use the same PCB footprint and mounting pattern.

Q: Which part should be selected for high-temperature, long-duration applications?

A: The 860160372009 is specified for extended thermal life (4000 hours at 105°C) and is the appropriate choice for applications requiring maximum reliability under sustained elevated temperature conditions.
