• Voltage Rating: 40 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR @ 100Hz: 18 mOhm (exact match required)
• Lifetime @ 85°C: 18000 Hrs (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Ripple Current @ 100 Hz: 17 A (exact match required)
• Ripple Current @ 10 kHz: 18.6 A (exact match required)
• Package Type: Radial, Can - Screw Terminals (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Lead Spacing: 22.20 mm (exact match required)
• Physical Dimensions: 51.00 mm diameter, 84.00 mm height (exact match required)

The ALS70A753KE040 qualifies as a parametric equivalent substitute, differing only in the base series designation (ALS70A versus ALS71H) while maintaining identical electrical performance and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71H753KE040 and ALS70A753KE040 are active products manufactured by KEMET with identical electrical and mechanical specifications. Selection between these parts is based on availability and inventory status rather than technical performance differences.

ALS71H753KE040 is the primary specification with 956 units in current inventory, providing the highest availability for immediate procurement.

ALS70A753KE040 serves as a direct parametric equivalent with 856 units available, suitable for use when the primary part is unavailable or when supply chain diversification is required.

Both parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. The identical electrical performance, mechanical dimensions, and environmental ratings ensure interchangeability in all general-purpose applications requiring 75000 µF, 40 V aluminum electrolytic capacitors with screw terminal connections.

Frequently Asked Questions (FAQ)

Q: Can ALS70A753KE040 be used as a direct replacement for ALS71H753KE040?

A: Yes. The ALS70A753KE040 is a parametric equivalent with identical capacitance (75000 µF), voltage rating (40 V), ESR (18 mOhm @ 100Hz), lifetime (18000 Hrs @ 85°C), ripple current specifications, physical dimensions, and package type. No circuit modifications or re-qualification are required.

Q: What is the difference between the ALS71H and ALS70A series designations?

A: The series designation difference reflects internal KEMET product line organization. Both series deliver identical electrical performance and mechanical specifications for this 75000 µF, 40 V capacitor model. The difference does not affect functional compatibility or application suitability.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts have identical dimensions: 51.00 mm diameter, 84.00 mm seated height, and 22.20 mm lead spacing. Screw terminal connections and chassis mount configuration are identical, ensuring direct mechanical interchangeability in PCB layouts and enclosure designs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ALS71H753KE040 and ALS70A753KE040 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Moisture sensitivity level is 1 (unlimited) for both parts.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current inventory availability and supplier lead times. Both parts are active products with identical specifications and long-term availability.

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

A: Both parts operate across -40°C to 85°C with a rated lifetime of 18000 hours at 85°C continuous operation.
