Substitute Part Grouping Explanation

Substitution eligibility for the ALS70P752NJ400 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part ALS70A752NJ400 qualifies as a parametric equivalent based on the following criteria:

Electrical Parameter Equivalence:

• Identical capacitance value: 7500 µF
• Identical rated voltage: 400 V
• Identical tolerance: ±20%
• Identical ESR: 29 mOhm @ 100Hz
• Identical lifetime rating: 20000 Hrs @ 85°C
• Identical operating temperature range: -40°C ~ 85°C
• Identical ripple current specifications at both 100 Hz and 10 kHz

Mechanical Parameter Equivalence:

• Identical package type: Radial, Can - Screw Terminals
• Identical mounting type: Chassis Mount
• Identical physical dimensions: 3.031" diameter, 4.606" height
• Identical lead spacing: 1.252" (31.80mm)

Compliance Equivalence:

• Both parts maintain RoHS3 compliance
• Both parts carry REACH unaffected status
• Both parts share identical MSL rating: 1 (Unlimited)

The substitution is based solely on parametric matching within the ALS70 series. Both parts originate from the same manufacturer (KEMET) and share identical electrical performance characteristics, thermal ratings, and physical form factors.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS70P752NJ400 and ALS70A752NJ400 are active products with full regulatory compliance. Selection between these parts is based on availability and inventory status rather than technical performance differentiation.

ALS70P752NJ400 is the primary part number with 952 units in current stock inventory.

ALS70A752NJ400 is the parametric equivalent with 1160 units in current stock inventory, offering increased availability.

Both parts satisfy identical electrical specifications, thermal performance requirements, and mechanical installation constraints. The difference between part numbers reflects internal KEMET product line designation within the ALS70 series but does not affect functional equivalence or circuit performance. Selection may be determined by procurement lead times, inventory allocation, or supply chain logistics.

Both parts maintain RoHS3 compliance and REACH unaffected status, supporting regulatory requirements for industrial and commercial applications.
