ALS71C134NF063 Equivalent & Substitute Parts

Part Overview

The ALS71C134NF063 is a 130000 µF aluminum electrolytic capacitor rated at 63 V with screw terminals, manufactured by KEMET in the ALS71 series. This component is classified as an active product and is designed for general-purpose applications requiring high capacitance values in chassis-mount configurations. The part is ROHS3 compliant and maintains a 20000-hour lifetime rating at 85°C operating temperature.

Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity when the primary part number becomes unavailable or when design requirements permit cross-series compatibility.

Substitute Part Grouping Explanation

Substitute parts for the ALS71C134NF063 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain constant:

• Capacitance Value: 130000 µF (exact match required)
• Voltage Rating: 63 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 9 mOhm (exact match required)
• Lifetime @ 85°C: 20000 Hrs (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Ripple Current Ratings: 27.3 A @ 100 Hz and 28.9 A @ 10 kHz (exact match required)
• Impedance: 10 mOhms (exact match required)
• Physical Dimensions: 77.00 mm diameter, 107.00 mm height, 31.80 mm lead spacing (exact match required)
• Package Type: Radial, Can - Screw Terminals (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Compliance: ROHS3 Compliant (exact match required)

The ALS70A134NF063 qualifies as a parametric equivalent because it maintains identical electrical performance and mechanical compatibility across all specified parameters, differing only in series designation (ALS70 versus ALS71).

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71C134NF063 and ALS70A134NF063 are active products manufactured by KEMET with identical electrical specifications and mechanical dimensions. Selection between these parts is based on availability and inventory status rather than technical performance differences.

The ALS71C134NF063 maintains 1148 pieces in current inventory stock. The ALS70A134NF063 maintains 1017 pieces in current inventory stock. Both parts carry ROHS3 compliance certification and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications.

For applications requiring 130000 µF capacitance at 63 V with screw terminal connections, either part number satisfies the specified electrical and mechanical requirements without design modification or performance degradation.
