Substitute Part Grouping Explanation

Substitute parts for the ALS71C752NJ400 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Electrical Parameters (Must Match):

• Capacitance: 7500 µF
• Voltage Rating: 400 V
• Tolerance: ±20%
• ESR @ 100Hz: 29 mOhm
• Lifetime @ 85°C: 20000 Hrs
• Operating Temperature Range: -40°C to 85°C
• Ripple Current @ 100 Hz: 16.7 A
• Ripple Current @ 10 kHz: 23.7 A

Mechanical Parameters (Must Match):

• Package Type: Radial, Can - Screw Terminals
• Mounting Type: Chassis Mount
• Lead Spacing: 31.80 mm
• Diameter: 77.00 mm
• Height - Seated (Max): 117.00 mm

The ALS70A752NJ400 meets all specified electrical and mechanical parameters, differing only in series designation (ALS70 vs. ALS71) while maintaining identical functional performance and physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71C752NJ400 and ALS70A752NJ400 are active products manufactured by KEMET with identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. Selection between these parts is based on availability and procurement requirements:

ALS71C752NJ400: 966 units in current inventory. Primary selection for immediate procurement.

ALS70A752NJ400: 1160 units in current inventory. Alternative selection for supply chain continuity or higher stock availability.

Both parts maintain ROHS3 compliance, REACH unaffected status, and identical performance characteristics across all specified electrical and mechanical parameters. No functional differences exist between these components in applications requiring 7500 µF, 400 V aluminum electrolytic capacitors with screw terminal construction.

Frequently Asked Questions (FAQ)

Q: Can ALS70A752NJ400 be used as a direct replacement for ALS71C752NJ400?

A: Yes. Both parts are manufactured by KEMET with identical capacitance (7500 µF), voltage rating (400 V), ESR (29 mOhm @ 100Hz), lifetime (20000 Hrs @ 85°C), and physical dimensions. All electrical and mechanical parameters match exactly.

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

A: The series designation indicates product line classification within KEMET's aluminum electrolytic capacitor portfolio. Both series meet identical performance specifications for this 7500 µF, 400 V application. The difference is administrative rather than functional.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical lead spacing (31.80 mm), diameter (77.00 mm), and maximum seated height (117.00 mm). They are mechanically interchangeable in chassis mount applications.

Q: Do both parts have the same regulatory compliance?

A: Yes. Both ALS71C752NJ400 and ALS70A752NJ400 are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1 - Unlimited).

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and procurement lead times. Both maintain active product status with KEMET.

Q: Are there any temperature or ripple current differences?

A: No. Both parts operate across -40°C to 85°C, support 16.7 A ripple current @ 100 Hz, and 23.7 A ripple current @ 10 kHz.
