Engineering Selection Recommendations

Primary Selection: ALS71A913MF063

The ALS71A913MF063 is the specified part number and should be used as the first choice when available. Current inventory status shows 767 units in stock. This part is in active production and carries full ROHS3 compliance and REACH unaffected status.

Alternative Selection: ALS70A913MF063

The ALS70A913MF063 is a direct parametric equivalent and may be selected when the primary part is unavailable. This substitute maintains identical electrical performance, mechanical dimensions, and compliance certifications. Current inventory shows 828 units in stock. Both parts are manufactured by KEMET and are in active production status.

The difference between ALS71 and ALS70 series designations reflects internal KEMET product line organization and does not affect functional equivalence for this specific capacitance and voltage rating combination.
