Parameter Comparison

Engineering Selection Recommendations

The ALS70A474NF025 is a direct parametric equivalent to the ALS71A474NF025 for applications requiring 470000 µF capacitance at 25 V with screw terminal connections. Both parts are manufactured by KEMET, maintain identical electrical performance specifications, and share the same mechanical form factor and mounting requirements.

Selection Basis:

Both parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring regulatory compliance across industrial and commercial applications. The series designation difference (ALS71 versus ALS70) reflects internal KEMET product line evolution but does not affect functional equivalence, as all critical electrical and mechanical parameters remain identical.

The ALS70A474NF025 is suitable for direct substitution in existing designs, PCB layouts, and assembly processes without modification to mounting hardware, terminal connections, or circuit board footprints. Both parts support the same ripple current specifications (28 A @ 100 Hz, 28.6 A @ 10 kHz) and maintain equivalent series resistance of 9 mOhm at 100 Hz.

Selection between these parts should be based on availability and supply chain requirements, as both deliver identical performance in general-purpose applications requiring high-capacitance energy storage.
