Parameter Comparison

Engineering Selection Recommendations

Both the ALS70C752NJ400 and ALS70A752NJ400 are active products manufactured by KEMET with full RoHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and procurement requirements rather than technical differentiation, as all electrical performance, mechanical dimensions, and regulatory certifications are identical.

The ALS70A752NJ400 represents a direct parametric equivalent suitable for applications where the ALS70C752NJ400 is unavailable. Both parts maintain the same 20000-hour lifetime rating at 85°C, identical ESR characteristics, and equivalent ripple current handling across low and high frequency ranges. The screw terminal connection method and chassis mount configuration remain consistent across both part numbers.

Component selection should prioritize inventory availability and lead time requirements. Current inventory shows 1160 units of ALS70A752NJ400 available compared to 938 units of ALS70C752NJ400, making the substitute part a viable alternative for immediate procurement needs without circuit redesign or performance compromise.
