Substitute Part Grouping Explanation

Substitute parts for the ALS70H752NP450 are identified based on strict electrical and mechanical parameter matching. The substitution criteria are:

Electrical Parameters (Must Match):

• Capacitance: 7500 µF
• Voltage Rating: 450 V
• Tolerance: ±20%
• ESR @ 100Hz: 31 mOhm
• Lifetime @ 85°C: 20000 Hrs
• Operating Temperature Range: -40°C ~ 85°C
• Ripple Current @ 100 Hz: 17.9 A
• Ripple Current @ 10 kHz: 25.3 A
• Impedance: 21 mOhms

Mechanical Parameters (Must Match):

• Lead Spacing: 1.252" (31.80 mm)
• Diameter: 3.031" (77.00 mm)
• Height - Seated (Max): 5.827" (148.00 mm)
• Package Type: Radial, Can - Screw Terminals
• Mounting Type: Chassis Mount

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The ALS70A752NP450 qualifies as a parametric equivalent substitute, as it maintains identical electrical performance and mechanical dimensions while differing only in the base product series designation (ALS70A versus ALS70H).

Parameter Comparison

Engineering Selection Recommendations

Both the ALS70H752NP450 and ALS70A752NP450 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 requirements rather than electrical or mechanical performance differences.

The ALS70H752NP450 currently maintains 829 pieces in stock inventory, while the ALS70A752NP450 maintains 813 pieces. Both components satisfy identical electrical specifications, mechanical dimensions, and regulatory compliance requirements for general purpose aluminum electrolytic capacitor applications.

For applications requiring 7500 µF capacitance at 450 V with screw terminal connectivity and chassis mount configuration, either part number provides equivalent performance within the specified operating temperature range of -40°C to 85°C and rated lifetime of 20000 hours at 85°C.

Frequently Asked Questions (FAQ)

Q: Can ALS70A752NP450 be used as a direct replacement for ALS70H752NP450?

A: Yes. Both parts are manufactured by KEMET and share identical electrical parameters (7500 µF, 450 V, 31 mOhm ESR @ 100Hz), mechanical dimensions (77.00 mm diameter, 148.00 mm height, 31.80 mm lead spacing), and package configuration (Radial, Can - Screw Terminals). The difference in base product series designation (ALS70A versus ALS70H) does not affect functional compatibility.

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

A: Yes. Both parts have identical lead spacing of 1.252" (31.80 mm), diameter of 3.031" (77.00 mm), and maximum seated height of 5.827" (148.00 mm). Both are configured for chassis mount with screw terminals.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ALS70H752NP450 and ALS70A752NP450 are ROHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited). Both carry ECCN EAR99 classification.
