Substitute Part Grouping Explanation

Substitute parts for the ALS71P622NF450 are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following critical parameters that must remain constant:

Electrical Parameters (Must Match):

• Capacitance: 6200 µF
• Voltage Rating: 450 V
• Tolerance: ±20%
• ESR @ 100Hz: 37 mOhm
• Lifetime @ 85°C: 20000 Hrs
• Operating Temperature Range: -40°C ~ 85°C
• Ripple Current @ 100 Hz: 15.6 A
• Ripple Current @ 10 kHz: 22.2 A

Mechanical Parameters (Must Match):

• Package Type: Radial, Can - Screw Terminals
• Lead Spacing: 1.252" (31.80mm)
• Diameter: 3.031" (77.00mm)
• Height - Seated (Max): 4.213" (107.00mm)
• Mounting Type: Chassis Mount
• Polarization: Polar

The ALS70A622NF450 qualifies as a parametric equivalent because it maintains identical electrical performance specifications and mechanical dimensions, differing only in the series designation (ALS70 versus ALS71), which reflects manufacturing evolution within the same product family while preserving all functional characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71P622NF450 and ALS70A622NF450 are Active status products manufactured by KEMET with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability and inventory considerations rather than technical differentiation.

The ALS70A622NF450 represents a manufacturing series evolution within KEMET's product portfolio. Both components satisfy identical electrical performance requirements, mechanical fit specifications, and regulatory compliance standards. The series designation change (ALS71 to ALS70) reflects product line consolidation or manufacturing process updates while maintaining backward compatibility in all functional parameters.

For applications requiring the 6200 µF, 450 V aluminum electrolytic capacitor specification with screw terminal connectivity, either part number is electrically and mechanically interchangeable. Component selection should prioritize availability, lead time, and cost considerations, as no technical performance differentiation exists between the two options.

Frequently Asked Questions (FAQ)

Q: Can ALS70A622NF450 be used as a direct replacement for ALS71P622NF450?

A: Yes. Both components are identical in all electrical parameters (capacitance, voltage rating, ESR, ripple current, lifetime), mechanical dimensions (diameter, height, lead spacing), and regulatory compliance (ROHS3, REACH). The series designation difference reflects manufacturing evolution, not functional change.

Q: Are the physical dimensions identical between these two part numbers?

A: Yes. Both components have identical lead spacing (1.252" / 31.80mm), diameter (3.031" / 77.00mm), and maximum seated height (4.213" / 107.00mm). They are mechanically interchangeable in chassis mount applications.

Q: Do both parts have the same ESR and ripple current ratings?

A: Yes. Both the ALS71P622NF450 and ALS70A622NF450 have 37 mOhm ESR @ 100Hz, 15.6 A ripple current @ 100 Hz, and 22.2 A ripple current @ 10 kHz. Electrical performance is identical.

Q: What is the operating temperature range for both parts?

A: Both components operate across -40°C to 85°C with a rated lifetime of 20000 hours at 85°C. Temperature specifications are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both ALS71P622NF450 and ALS70A622NF450 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the capacitance tolerance for these parts?

A: Both components have ±20% capacitance tolerance, meaning the actual capacitance value will fall within 4960 µF to 7440 µF for the 6200 µF nominal rating.

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

A: Yes. Both parts are rated for 22.2 A ripple current @ 10 kHz, indicating suitability for high-frequency ripple current environments. The 25 mOhm impedance specification supports high-frequency operation.

Q: What mounting configuration do these capacitors use?

A: Both components are chassis mount with radial, can-style screw terminals. They are designed for direct PCB or chassis mounting with screw-based electrical connections.
