Substitute Part Grouping Explanation

Substitution of the ALS71H752NP450 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part ALS70A752NP450 qualifies as a direct equivalent based on the following criteria:

Electrical Parameter Equivalence:

• Identical capacitance value: 7500 µF
• Identical voltage rating: 450 V
• Identical tolerance: ±20%
• Identical ESR: 31 mOhm @ 100Hz
• Identical lifetime specification: 20000 Hrs @ 85°C
• Identical operating temperature range: -40°C ~ 85°C
• Identical ripple current ratings: 17.9 A @ 100 Hz and 25.3 A @ 10 kHz
• Identical impedance: 21 mOhms

Mechanical Parameter Equivalence:

• Identical lead spacing: 1.252" (31.80 mm)
• Identical physical dimensions: 3.031" Dia (77.00 mm)
• Identical height: 5.827" (148.00 mm)
• Identical mounting type: Chassis Mount
• Identical package configuration: Radial, Can - Screw Terminals

Compliance Equivalence:

• Both parts are ROHS3 Compliant
• Both parts have MSL rating of 1 (Unlimited)
• Both parts are REACH Unaffected
• Both parts share identical ECCN and HTSUS classifications

The only difference between these parts is the series designation (ALS71 versus ALS70), which reflects internal KEMET product line organization and does not affect functional performance or interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71H752NP450 and ALS70A752NP450 are Active product status components manufactured by KEMET with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and inventory status rather than technical performance differentiation.

The ALS71H752NP450 is the primary part number with 816 pieces in stock. The ALS70A752NP450 substitute is available with 813 pieces in stock and provides equivalent functionality for applications requiring 7500 µF capacitance at 450 V with screw terminal connections.

Both parts meet industrial compliance requirements and are suitable for direct substitution in chassis-mounted power supply and general-purpose filtering applications. No performance degradation or circuit redesign is required when substituting between these part numbers.
