Parameter Comparison

Engineering Selection Recommendations

Both the ALS70H513NF100 and ALS70A513NF100 are Active products manufactured by KEMET with full ROHS3 compliance and REACH unaffected status. The parts are electrically and mechanically identical across all specified parameters. Selection between these two part numbers may be based on inventory availability and procurement lead times. The ALS70A513NF100 currently maintains higher inventory levels at 786 pieces compared to 718 pieces for the ALS70H513NF100. Both parts support general-purpose applications requiring 51000 µF capacitance at 100 V with screw terminal connectivity for chassis-mounted installations.

Frequently Asked Questions (FAQ)

Q: Can the ALS70A513NF100 be used as a direct replacement for the ALS70H513NF100?

A: Yes. The ALS70A513NF100 is a parametric equivalent substitute. All electrical specifications, mechanical dimensions, lead spacing, mounting configuration, and compliance certifications are identical. Direct substitution is supported without circuit redesign or board layout modification.

Q: What is the difference between the ALS70H and ALS70A base product numbers?

A: The base product numbers ALS70H and ALS70A represent different internal KEMET product designations within the ALS70 series. For the 51000 µF, 100 V, ±20% tolerance configuration, both base numbers deliver identical electrical and mechanical performance.

Q: Are the screw terminal connections identical between these parts?

A: Yes. Both parts feature radial, can-style screw terminals with identical lead spacing of 1.252" (31.80mm). Terminal compatibility is confirmed for direct board-level substitution.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the ALS70H513NF100 and ALS70A513NF100 are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (Unlimited). Compliance status is identical.

Q: What is the maximum ripple current rating for these capacitors?

A: The maximum ripple current is 27.9 A at 10 kHz high frequency operation. At low frequency (100 Hz), the ripple current rating is 25.7 A. Both ratings apply equally to both part numbers.

Q: Can these capacitors be used in applications requiring extended lifetime at elevated temperatures?

A: Both parts are rated for 20000 hours of operation at 85°C. Operating temperature range is -40°C to 85°C. Applications requiring operation beyond these specifications require alternative component selection.

Q: What is the ESR (Equivalent Series Resistance) specification?

A: The ESR is 12 mOhm measured at 100 Hz for both part numbers. This specification is critical for ripple current handling and thermal performance in high-frequency switching applications.

Q: Are these parts suitable for surface mount applications?

A: No. Both the ALS70H513NF100 and ALS70A513NF100 are chassis-mount components with screw terminals designed for through-hole or direct panel mounting. Surface mount alternatives require different part selection.
