Parameter Comparison

Engineering Selection Recommendations

Both the ALS71H752NF400 and ALS70A752NF400 are active production parts manufactured by KEMET with full ROHS3 compliance and REACH unaffected status. The parts are electrically and mechanically identical across all specified parameters. Selection between these two part numbers is based on availability and series designation (ALS71 versus ALS70). Both parts maintain the same performance characteristics, thermal ratings, and compliance certifications. The choice between them does not affect circuit performance or reliability when all electrical and mechanical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can ALS70A752NF400 be used as a direct replacement for ALS71H752NF400?

A: Yes. Both parts are identical in capacitance (7500 µF), voltage rating (400 V), ESR (29 mOhm @ 100Hz), lifetime (20000 Hrs @ 85°C), and all mechanical dimensions. They share the same screw terminal package, chassis mount configuration, and lead spacing (1.252"). Both are ROHS3 compliant and REACH unaffected.

Q: What is the difference between the ALS71 and ALS70 series?

A: The series designation indicates different product lines within KEMET's aluminum electrolytic capacitor portfolio. Both series meet identical electrical and mechanical specifications for this 7500 µF, 400 V application. The difference is in the internal design generation or manufacturing process, not in performance parameters.

Q: Are the physical dimensions identical between these 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). They are fully interchangeable in chassis mount applications.

Q: Do both parts support the same ripple current ratings?

A: Yes. Both parts are rated for 16.4 A ripple current at 100 Hz and 23 A ripple current at 10 kHz, with identical impedance of 19 mOhms.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -40°C to 85°C with a rated lifetime of 20,000 hours at 85°C.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, with Moisture Sensitivity Level 1 (unlimited). They carry identical compliance certifications.
