ALS81C752NF350 Equivalent & Substitute Parts

Part Overview

The ALS81C752NF350 is a 7500 µF, 350 V aluminum electrolytic capacitor with radial, can-mounted screw terminals manufactured by KEMET. This component is classified as Active product status and is designed for general-purpose applications requiring high-capacitance energy storage in chassis-mounted configurations. The part operates across a temperature range of -40°C to 105°C with a rated lifetime of 9000 hours at 105°C.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when design flexibility permits selection from qualified alternatives that maintain identical electrical and mechanical performance specifications.

Frequently Asked Questions (FAQ)

Q: Can the ALS80A752NF350 be used as a direct replacement for the ALS81C752NF350?

A: Yes. The ALS80A752NF350 is a parametric equivalent with identical capacitance (7500 µF), voltage rating (350 V), ESR (29 mOhm @ 100Hz), lifetime (9000 Hrs @ 105°C), operating temperature range (-40°C to 105°C), ripple current specifications, and mechanical dimensions. Both parts use identical screw terminal mounting and chassis mount configuration.

Q: Are there any differences in the physical package between these parts?

A: No. Both parts share identical mechanical specifications: 3.031" diameter (77.00mm), 4.213" maximum seated height (107.00mm), 1.252" lead spacing (31.80mm), and radial can-mounted screw terminal configuration.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both ALS81C752NF350 and ALS80A752NF350 are ROHS3 Compliant and REACH Unaffected. Both parts carry identical ECCN (EAR99) and HTSUS (8532.22.0085) classifications.

Q: What is the difference between the ALS81 and ALS80 series designations?

A: The series designation reflects internal KEMET product line organization. Both series maintain identical electrical and mechanical specifications for this 7500 µF, 350 V capacitor model. The difference is organizational only and does not affect performance or compatibility.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Identical lead spacing (1.252" / 31.80mm), mounting type (chassis mount), and package configuration (radial, can - screw terminals) ensure direct mechanical and electrical interchangeability in existing designs without modification.
