Engineering Selection Recommendations

Selection of substitute parts depends on application requirements for operating temperature, voltage margin, and component lifetime:

For Extended Temperature Operation (up to 105°C): Use 860020572003 (WCAP-ATG5 series) to maintain 35 V rating with extended upper temperature limit and 105°C lifetime rating.

For Voltage Margin Increase: Use 860010672009 or 860010772009 (WCAP-ATG8 series) to upgrade to 50 V or 63 V respectively while maintaining the same thermal and lifetime characteristics as the original part.

For Combined Temperature and Voltage Upgrade: Use 860020672010 or 860020772010 (WCAP-ATG5 series) to achieve both 105°C operation and higher voltage ratings (50 V or 63 V).

For Extended Temperature Range (-55°C to 105°C): Use 860080772001 (WCAP-ATLI series) for 63 V rating with expanded low-temperature capability.

For Extended Lifetime (4000 Hrs @ 105°C): Use 860160572001 or 860160672009 (WCAP-ATLL series) with operating range -55°C to 105°C.
