Engineering Selection Recommendations

Both the ALS70P912NP400 and ALS70A912NP400 are Active products manufactured by KEMET and are fully compliant with RoHS3 and REACH regulations. The parts are electrically and mechanically identical across all specified parameters, including capacitance, voltage rating, ESR, ripple current ratings, thermal lifetime, operating temperature range, and physical dimensions.

Selection between these parts is based on inventory availability and sourcing requirements. The ALS70A912NP400 currently maintains higher inventory levels (1100 Pcs) compared to the ALS70P912NP400 (944 Pcs). Both parts are suitable for direct substitution in applications requiring 9100 µF, 400 V aluminum electrolytic capacitors with screw terminal connections and chassis mounting.

Frequently Asked Questions (FAQ)

Q: Can ALS70A912NP400 be used as a direct replacement for ALS70P912NP400?

A: Yes. Both parts are electrically and mechanically identical. All electrical parameters (capacitance, voltage, ESR, ripple current, impedance, lifetime) and mechanical parameters (package type, dimensions, lead spacing, mounting configuration) are identical. Direct substitution is supported without circuit modification.

Q: What is the difference between ALS70P and ALS70A part numbers?

A: The difference between ALS70P and ALS70A designations relates to internal construction variants within the KEMET ALS70 series. Both variants deliver identical electrical and mechanical performance for the 9100 µF, 400 V specification. The substitution is valid based on parametric equivalence.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry identical compliance certifications: ROHS3 Compliant, REACH Unaffected, and Moisture Sensitivity Level 1 (Unlimited). Both are suitable for applications with equivalent regulatory requirements.

Q: What are the critical parameters for substitution in this capacitor category?

A: For aluminum electrolytic capacitors with screw terminals, the critical substitution parameters are: capacitance value, voltage rating, tolerance, ESR, ripple current ratings at specified frequencies, thermal lifetime rating, operating temperature range, package type, physical dimensions, and lead spacing. All these parameters must match for direct substitution.

Q: Can these parts be used interchangeably in existing PCB designs or chassis layouts?

A: Yes. The identical physical dimensions (3.031" diameter, 5.827" height, 1.252" lead spacing) and chassis mount configuration ensure mechanical compatibility with existing mounting hardware and circuit board layouts.
