• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Unaffected status (maintained)

The substitute part ALS70A513KF063 meets all specified criteria for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

Both ALS71H513KF063 and ALS70A513KF063 are Active product status components manufactured by KEMET with full RoHS3 compliance and REACH Unaffected designation. The parts are electrically and mechanically identical across all specified parameters.

Selection between these parts is based on inventory availability and supply chain considerations. The ALS70A513KF063 currently maintains higher inventory levels (1050 Pcs) compared to ALS71H513KF063 (907 Pcs), making it suitable for applications where supply continuity is a priority.

Both components satisfy general-purpose aluminum electrolytic capacitor applications requiring 51000 µF capacitance at 63 V with extended operational lifetime and low ESR characteristics.

Frequently Asked Questions (FAQ)

Q: Can ALS70A513KF063 be used as a direct replacement for ALS71H513KF063?

A: Yes. Both parts are electrically and mechanically equivalent across all specified parameters, including capacitance, voltage rating, ESR, ripple current, physical dimensions, and screw terminal configuration. Direct substitution is supported without circuit modification.

Q: Are there differences in the series designation between ALS71H and ALS70A?

A: The series designation (ALS71 vs. ALS70) reflects internal KEMET product line organization. The electrical and mechanical specifications provided in this reference are identical, confirming functional equivalence for the specified part numbers.

Q: What are the critical parameters that must match for substitution?

A: Capacitance (51000 µF), rated voltage (63 V), tolerance (±20%), ESR @ 100Hz (14 mOhm), lifetime @ 85°C (18000 Hrs), operating temperature range (-40°C to 85°C), ripple current specifications, package type (Radial, Can - Screw Terminals), mounting type (Chassis Mount), and physical dimensions (22.20 mm lead spacing, 51.00 mm diameter, 107.00 mm height) must all match exactly.

Q: Are both parts RoHS compliant?

A: Yes. Both ALS71H513KF063 and ALS70A513KF063 are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status.

Q: What is the maximum operating temperature for these capacitors?

A: The maximum operating temperature is 85°C. The specified lifetime of 18000 hours applies at this temperature. Operating below 85°C extends component life.

Q: Can these capacitors be used in high-frequency applications?

A: These capacitors are rated for ripple current at both low frequency (19.1 A @ 100 Hz) and high frequency (21.5 A @ 10 kHz). The impedance specification of 13 mOhms supports applications across this frequency range.
