Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ALS71P164NP063 are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following critical parameters:

Electrical Parameters (Must Match):

• Capacitance: 160000 µF
• Voltage Rating: 63 V
• Tolerance: ±20%
• ESR @ 100Hz: 8 mOhm
• Lifetime @ 85°C: 20000 Hrs
• Operating Temperature Range: -40°C to 85°C
• Ripple Current @ 100 Hz: 30.6 A
• Ripple Current @ 10 kHz: 32.2 A

Mechanical Parameters (Must Match):

• Lead Spacing: 31.80 mm
• Diameter: 77.00 mm
• Height - Seated (Max): 148.00 mm
• Package / Case: Radial, Can - Screw Terminals
• Mounting Type: Chassis Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Polarization: Polar

The ALS70A164NP063 meets all specified electrical and mechanical parameters and is therefore classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71P164NP063 and ALS70A164NP063 are Active product status components manufactured by KEMET with full ROHS3 compliance. Selection between these parts is based on inventory availability and supply chain considerations rather than electrical or mechanical performance differences.

The ALS71P164NP063 (ALS71 series) currently maintains 908 pieces in stock inventory. The ALS70A164NP063 (ALS70 series) maintains 1182 pieces in stock inventory. Both components satisfy identical electrical specifications, mechanical dimensions, and regulatory compliance requirements for direct substitution in chassis-mounted aluminum electrolytic capacitor applications.

Frequently Asked Questions (FAQ)

Q: Can ALS70A164NP063 be used as a direct replacement for ALS71P164NP063?

A: Yes. The ALS70A164NP063 is a parametric equivalent substitute. All electrical parameters (capacitance, voltage rating, ESR, ripple current, lifetime), mechanical dimensions (lead spacing, diameter, height), and compliance certifications (ROHS3) are identical.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: capacitance value (160000 µF), voltage rating (63 V), tolerance (±20%), ESR @ 100Hz (8 mOhm), lifetime @ 85°C (20000 Hrs), operating temperature range (-40 to 85°C), ripple current specifications, lead spacing (31.80 mm), physical dimensions (77.00 mm diameter, 148.00 mm height), and package type (Radial, Can - Screw Terminals).

Q: Are there any differences in the series designation between ALS71P and ALS70A?

A: The series designation differs (ALS71 versus ALS70), but all specified electrical and mechanical parameters are identical. Both series are manufactured by KEMET and maintain Active product status.
