Substitute Part Grouping Explanation

Substitution of the ALS71U134NF063 with equivalent parts is determined by strict parametric matching across all critical electrical and mechanical specifications. The substitute part ALS70A134NF063 qualifies as a direct equivalent based on the following criteria:

Matching Parameters (Substitution Basis):

• Capacitance: 130000 µF (identical)
• Voltage Rating: 63 V (identical)
• Tolerance: ±20% (identical)
• ESR @ 100Hz: 9 mOhm (identical)
• Lifetime @ 85°C: 20000 Hrs (identical)
• Operating Temperature Range: -40°C ~ 85°C (identical)
• Ripple Current @ 100 Hz: 27.3 A (identical)
• Ripple Current @ 10 kHz: 28.9 A (identical)
• Impedance: 10 mOhms (identical)
• Lead Spacing: 1.252" (31.80 mm) (identical)
• Physical Dimensions: 3.031" Dia × 4.213" Height (identical)
• Package Type: Radial, Can - Screw Terminals (identical)
• Mounting Type: Chassis Mount (identical)
• Polarization: Polar (identical)
• RoHS Status: ROHS3 Compliant (identical)
• MSL Rating: 1 (Unlimited) (identical)

The primary difference between the main part and substitute is the series designation (ALS71 versus ALS70) and base product number (ALS71U versus ALS70A), which reflects internal KEMET product line organization without affecting electrical or mechanical performance in the specified application.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71U134NF063 and ALS70A134NF063 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 procurement requirements rather than technical performance differentiation.

The ALS71U134NF063 maintains 899 pieces in current inventory stock, while the ALS70A134NF063 maintains 1017 pieces in current inventory stock. Both parts satisfy identical electrical specifications, mechanical dimensions, and regulatory compliance requirements for general purpose aluminum electrolytic capacitor applications requiring 130000 µF capacitance at 63 V with screw terminal connections.

Component selection should prioritize inventory availability and lead time requirements. No technical re-qualification is necessary when transitioning between these part numbers within the same design application, as all specified parameters remain constant.
