Substitute Part Grouping Explanation

Substitution of the ALS70C912NP400 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part ALS70A912NP400 qualifies as a parametric equivalent based on the following criteria:

Electrical Equivalence:

• Identical capacitance value: 9100 µF
• Identical rated voltage: 400 V
• Identical tolerance: ±20%
• Identical ESR: 24 mOhm @ 100 Hz
• 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 Equivalence:

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

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 substitute part differs only in the base product number designation (ALS70A versus ALS70C), indicating a variant within the same product family with identical performance characteristics and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS70C912NP400 and ALS70A912NP400 are Active products manufactured by KEMET with full compliance to ROHS3 and REACH requirements. Selection between these parts is based on availability and inventory status rather than technical performance differentiation.

The ALS70C912NP400 maintains current inventory of 685 pieces. The ALS70A912NP400 provides an alternative source with 1100 pieces in stock. Both parts deliver identical electrical performance, mechanical compatibility, and regulatory compliance. Component selection should prioritize availability against project timeline requirements and supply chain strategy.

No technical re-qualification is necessary when substituting between these parts, as all critical parameters—capacitance, voltage rating, ESR, ripple current handling, thermal performance, and physical form factor—are identical across both designations.
