ALS71G623NP100 Equivalent & Substitute Parts

Part Overview

The ALS71G623NP100 is a 62000 µF, 100 V aluminum electrolytic capacitor manufactured by KEMET in the ALS71 series. This radial, can-style capacitor with screw terminals is designed for general-purpose applications requiring high capacitance values at moderate voltage ratings. The part is currently Active in product status with 866 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or design flexibility within the same application category.

Parameter Comparison

Engineering Selection Recommendations

Both the ALS71G623NP100 and ALS70A623NP100 are Active products manufactured by KEMET with full ROHS3 compliance and REACH unaffected status. The parts are electrically and mechanically identical across all specified parameters, including capacitance, voltage rating, ESR, ripple current ratings, physical dimensions, and thermal characteristics.

Selection between these two parts should be based on:

1. Inventory Availability: The ALS70A623NP100 has 1026 units in stock compared to 866 units for the ALS71G623NP100, providing additional supply margin.

2. Series Designation: The ALS71G623NP100 belongs to the ALS71 series, while the ALS70A623NP100 belongs to the ALS70 series. Both series are current KEMET product lines with identical electrical and mechanical specifications for this capacitance and voltage combination.

3. Compliance Requirements: Both parts meet identical regulatory requirements (ROHS3 Compliant, REACH Unaffected, MSL 1).

4. Application Continuity: Direct substitution is supported without circuit redesign, PCB layout modification, or thermal management changes.

Frequently Asked Questions (FAQ)

Q: Can the ALS70A623NP100 be used as a direct replacement for the ALS71G623NP100?

A: Yes. The ALS70A623NP100 is a parametric equivalent with identical electrical specifications (62000 µF, 100 V, ±20% tolerance, 11 mOhm ESR @ 100Hz, 20000 Hrs @ 85°C), identical mechanical dimensions (3.031" Dia, 5.827" height, 1.252" lead spacing), and identical package type (Radial, Can - Screw Terminals). No circuit modifications are required.

Q: Are there any differences in thermal performance between these parts?

A: No. Both parts have identical operating temperature ranges (-40°C ~ 85°C), identical lifetime ratings (20000 Hrs @ 85°C), and identical ripple current specifications (28.9 A @ 100 Hz, 31.2 A @ 10 kHz).

Q: Do both parts have the same physical footprint?

A: Yes. Both parts have identical dimensions: 3.031" diameter (77.00mm), 5.827" maximum seated height (148.00mm), and 1.252" lead spacing (31.80mm). They are both Chassis Mount components with Radial, Can - Screw Terminals configuration.

Q: What is the difference between the ALS71 and ALS70 series?

A: Both series are KEMET aluminum electrolytic capacitor product lines. For the 62000 µF, 100 V specification, the electrical and mechanical parameters are identical. Series designation reflects internal KEMET product architecture but does not affect performance or compatibility in this application.

Q: Are both parts RoHS compliant?

A: Yes. Both the ALS71G623NP100 and ALS70A623NP100 are ROHS3 Compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status.

Q: Which part should I select if both are available?

A: Selection can be based on inventory availability and supply chain considerations. The ALS70A623NP100 has higher current stock (1026 units vs. 866 units). Both parts are Active products with identical specifications and compliance certifications.
