Frequently Asked Questions (FAQ)

Q: Can the ALS70A513NF100 be used as a direct replacement for the ALS71H513NF100?

A: Yes. The ALS70A513NF100 is a parametric equivalent with identical electrical specifications (51000 µF, 100 V, ±20% tolerance, 12 mOhm ESR), identical mechanical dimensions (77.00 mm diameter, 107.00 mm height, 31.80 mm lead spacing), and identical package configuration (Radial, Can - Screw Terminals). Both parts are ROHS3 compliant and maintain the same operating temperature range and lifetime rating.

Q: What are the key parameters that determine substitutability for this capacitor?

A: Substitutability is determined by exact equivalence in: capacitance value (51000 µF), voltage rating (100 V), tolerance (±20%), ESR at 100Hz (12 mOhm), lifetime at 85°C (20000 Hrs), operating temperature range (-40°C to 85°C), ripple current specifications, physical dimensions, lead spacing, and mounting configuration. All these parameters must match exactly between the original and substitute part.

Q: Are there any differences in the series designation between ALS71H513NF100 and ALS70A513NF100?

A: The parts belong to different KEMET series: ALS71 and ALS70 respectively. However, this series designation difference does not affect electrical or mechanical compatibility, as all functional parameters remain identical.

Q: What is the significance of the screw terminal configuration?

A: The screw terminal configuration is a mechanical interface specification that determines how the capacitor connects to the circuit board or chassis. Both substitute parts use identical Radial, Can - Screw Terminals, ensuring compatibility with existing mounting hardware and connection points.

Q: Can these capacitors be used in applications requiring different voltage ratings?

A: No. Both parts are rated for 100 V operation. Use in applications requiring different voltage ratings requires selection of alternative part numbers with appropriate voltage specifications.

Q: What does the ±20% tolerance specification mean for capacitance?

A: The ±20% tolerance indicates that the actual capacitance value may vary between 40800 µF and 61200 µF while remaining within specification. Both substitute parts share this identical tolerance specification.
