• Tolerance: ±20%
• ESR @ 100Hz: 29 mOhm
• Lifetime @ 85°C: 20000 Hrs
• Operating Temperature Range: -40°C ~ 85°C
• Ripple Current @ 100 Hz: 16.7 A
• Ripple Current @ 10 kHz: 23.7 A

Mechanical Parameters (Must Match Exactly):

• Package Type: Radial, Can - Screw Terminals
• Mounting Type: Chassis Mount
• Physical Dimensions: 3.031" Dia (77.00mm)
• Height - Seated (Max): 4.606" (117.00mm)
• Lead Spacing: 1.252" (31.80mm)

Compliance Parameters (Must Match Exactly):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The ALS70A752NJ400 meets all substitution criteria as a parametric equivalent within the KEMET aluminum electrolytic capacitor product family.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71P752NJ400 and ALS70A752NJ400 are active products manufactured by KEMET with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on inventory availability and procurement lead times, as all electrical, mechanical, and compliance parameters are identical.

The ALS71P752NJ400 (ALS71 series) and ALS70A752NJ400 (ALS70 series) represent different product generations within KEMET's aluminum electrolytic capacitor portfolio. Both maintain the same performance specifications, dimensional footprint, and regulatory compliance profile. The distinction between series designations reflects internal KEMET product architecture but does not affect functional equivalence in circuit applications.

For applications requiring 7500 µF capacitance at 400 V with screw terminal connectivity and chassis mount configuration, either part number satisfies the electrical and mechanical requirements without circuit redesign or board layout modification.

Frequently Asked Questions (FAQ)

Q: Can ALS70A752NJ400 be used as a direct replacement for ALS71P752NJ400?

A: Yes. The ALS70A752NJ400 is a parametric equivalent. All electrical specifications (capacitance, voltage rating, ESR, ripple current, lifetime), mechanical dimensions (diameter, height, lead spacing), and compliance certifications (ROHS3, REACH) are identical. No circuit modifications or PCB layout changes are required.

Q: Are there any differences in the screw terminal specifications between these parts?

A: No. Both parts feature identical radial, can-style construction with screw terminals. Lead spacing is 1.252" (31.80mm) for both components. Terminal compatibility with existing hardware is maintained.

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

A: The series designation reflects KEMET's internal product architecture and manufacturing generation. The ALS70 series represents a current product line variant. From an engineering standpoint, the series change does not affect electrical performance, mechanical fit, or application compatibility.

Q: Do both parts meet the same environmental and compliance standards?

A: Yes. Both ALS71P752NJ400 and ALS70A752NJ400 are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (unlimited). They meet identical regulatory requirements for industrial and commercial applications.

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

A: Both parts operate across -40°C to 85°C. The rated lifetime of 20000 hours applies at 85°C maximum operating temperature for both components.

Q: Are there inventory or lead time considerations for selecting between these parts?

A: Current inventory shows 1109 units of ALS71P752NJ400 and 1160 units of ALS70A752NJ400 in stock. Selection may be based on immediate availability and procurement timelines, as both parts are active products with equivalent supply status.

Q: Can these parts be used interchangeably in existing designs without qualification testing?

A: Parametric equivalence is established across all specified electrical and mechanical parameters. Design qualification decisions remain the responsibility of the implementing engineer based on application-specific requirements and organizational quality standards.
