ALS70C753QC063 Equivalent & Substitute Parts

Part Overview

The ALS70C753QC063 is a 75000 µF, 63 V aluminum electrolytic capacitor manufactured by KEMET in the ALS70 series. This component features radial, can-style construction with screw terminals, designed for chassis mount applications requiring high capacitance values in general-purpose circuits. The part maintains an active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when inventory constraints require component alternatives that maintain identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitute parts for the ALS70C753QC063 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

Electrical Parameters (Must Match Exactly):

• Capacitance: 75000 µF
• Voltage Rating: 63 V
• Tolerance: ±20%
• ESR @ 100Hz: 14 mOhm
• Lifetime @ 85°C: 20000 Hrs
• Operating Temperature Range: -40°C to 85°C
• Ripple Current @ 100 Hz: 22.3 A
• Ripple Current @ 10 kHz: 24 A
• Impedance: 13 mOhms

Mechanical Parameters (Must Match Exactly):

• Package Type: Radial, Can - Screw Terminals
• Lead Spacing: 31.80 mm
• Diameter: 90.00 mm
• Height - Seated (Max): 69.00 mm
• Mounting Type: Chassis Mount

Compliance Parameters (Must Match Exactly):

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

The ALS70A753QC063 qualifies as a parametric equivalent substitute because it maintains identical values across all electrical, mechanical, and compliance specifications while differing only in the series designation (ALS70A versus ALS70C).

Parameter Comparison

Engineering Selection Recommendations

Both the ALS70C753QC063 and ALS70A753QC063 are active products manufactured by KEMET with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

Inventory Availability: The ALS70A753QC063 maintains 1124 pieces in stock compared to 1043 pieces for the ALS70C753QC063. Either part may be selected based on current inventory levels and procurement lead times.

Compliance Requirements: Both parts satisfy identical regulatory requirements including ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating. No compliance differentiation exists between the two part numbers.

Electrical Performance: Identical electrical specifications across capacitance, voltage rating, ESR, ripple current ratings, impedance, and operating temperature range ensure direct functional equivalence in circuit applications.

Mechanical Compatibility: Identical package dimensions, lead spacing, and chassis mount configuration ensure direct mechanical interchangeability in existing PCB layouts and mechanical assemblies.

Frequently Asked Questions (FAQ)
