Parameter Comparison

Engineering Selection Recommendations

Both the ALS71P752NF400 and ALS70A752NF400 are Active products manufactured by KEMET with identical electrical specifications and mechanical dimensions. Both parts are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements. The primary difference between these parts is the series designation (ALS71 versus ALS70), which reflects internal design iterations within KEMET's product line while maintaining full parameter equivalence.

Selection between these parts should be based on availability and application requirements. Both parts are suitable for general purpose applications requiring 7500 µF capacitance at 400 V with screw terminal connections for chassis mounting. The identical ESR, ripple current ratings, and thermal specifications ensure equivalent performance in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the ALS70A752NF400 be used as a direct replacement for the ALS71P752NF400?

A: Yes. The ALS70A752NF400 is a parametric equivalent substitute. All electrical parameters, mechanical dimensions, and performance ratings are identical. Both parts feature the same capacitance (7500 µF), voltage rating (400 V), ESR (29 mOhm @ 100Hz), and thermal specifications (20000 Hrs @ 85°C). Screw terminal connections and chassis mount configuration are identical.

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

A: No. Both the ALS71P752NF400 and ALS70A752NF400 are RoHS3 compliant, REACH unaffected, and carry identical MSL ratings (1 - Unlimited). Both parts meet the same regulatory and environmental standards.

Q: What is the significance of the series designation change from ALS71 to ALS70?

A: The series designation reflects KEMET's internal product line organization. The change from ALS71 to ALS70 does not affect electrical performance, mechanical compatibility, or application suitability. Both series maintain identical specifications for this 7500 µF, 400 V capacitor model.

Q: Are the physical dimensions identical for both parts?

A: Yes. Both parts have identical dimensions: 3.031" diameter (77.00mm), 4.213" maximum seated height (107.00mm), and 1.252" lead spacing (31.80mm). Both are packaged as radial, can-style capacitors with screw terminals suitable for chassis mount installation.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. The ALS70A752NF400 can be substituted for the ALS71P752NF400 without design modifications. Identical lead spacing, mounting configuration, and electrical specifications ensure direct compatibility in existing PCB layouts and circuit designs.
