Substitute Part Grouping Explanation

Substitution eligibility for the ALS71C752NP450 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Capacitance: 7500 µF (exact match required)
• Voltage Rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 31 mOhm (exact match required)
• Lifetime @ 85°C: 20000 Hrs (exact match required)
• Operating Temperature: -40°C to 85°C (exact match required)
• Ripple Current @ 100Hz: 17.9 A (exact match required)
• Ripple Current @ 10kHz: 25.3 A (exact match required)

Mechanical Compatibility Criteria:

• Lead Spacing: 31.80 mm (exact match required)
• Diameter: 77.00 mm (exact match required)
• Height: 148.00 mm (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Package: Radial, Can - Screw Terminals (exact match required)

Compliance Criteria:

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

The substitute part ALS70A752NP450 meets all electrical and mechanical equivalence criteria, differing only in product series designation (ALS70 versus ALS71).

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71C752NP450 and ALS70A752NP450 are Active product status components manufactured by KEMET with full ROHS3 compliance and REACH Unaffected designation. Selection between these parts is based on availability and supply chain considerations rather than technical performance differentiation.

The ALS71C752NP450 maintains current inventory of 1051 pieces. The ALS70A752NP450 substitute maintains inventory of 813 pieces. Both parts satisfy identical electrical performance requirements, mechanical fit specifications, and regulatory compliance frameworks.

Component selection should prioritize availability status and lead time requirements within the procurement cycle. No technical re-qualification is required when transitioning between these parts within the same application circuit.

Frequently Asked Questions (FAQ)

Q: Can ALS70A752NP450 be used as a direct replacement for ALS71C752NP450?

A: Yes. The ALS70A752NP450 is a direct parametric equivalent. All electrical specifications, mechanical dimensions, and compliance certifications are identical. No circuit modifications or re-testing are required.

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

A: The series designation reflects internal KEMET product line organization. From an engineering standpoint, both series deliver identical performance across all specified parameters for this capacitance and voltage rating.

Q: Are the screw terminal connections identical between both parts?

A: Yes. Both parts feature Radial, Can - Screw Terminals with identical lead spacing of 31.80 mm. PCB layout and mounting hardware remain unchanged.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both ALS71C752NP450 and ALS70A752NP450 are ROHS3 compliant, REACH Unaffected, and carry identical environmental classification (MSL 1 - Unlimited).

Q: What is the maximum ripple current these capacitors can handle?

A: At 10 kHz, the maximum ripple current is 25.3 A. At 100 Hz, the maximum ripple current is 17.9 A. Both specifications are identical across both part numbers.

Q: Can these capacitors operate below -40°C or above 85°C?

A: No. The specified operating temperature range is -40°C to 85°C. Operation outside this range voids the 20,000-hour lifetime rating at 85°C.

Q: What does the ±20% tolerance mean for the 7500 µF capacitance?

A: The actual capacitance value will fall between 6000 µF and 9000 µF. Circuit design must accommodate this tolerance band.

Q: Is the 31 mOhm ESR specification critical for my application?

A: ESR directly affects ripple voltage and heat dissipation. If your circuit requires lower ESR performance, these parts may not be suitable. Verify ESR requirements against your power supply design specifications.
