AMI-80 Equivalent & Substitute Parts

Part Overview

The AMI-80 is a high-amperage stud mount fuse manufactured by Eaton - Bussmann Electrical Division, rated for 80A AC/DC applications. This component is classified as Active product status and maintains RoHS compliance. Substitute parts are identified when equivalent electrical ratings, mechanical mounting compatibility, and regulatory certifications align with the original specification, enabling direct replacement in applications where the primary part is unavailable or requires alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMI-80 are qualified based on the following criteria:

• Current Rating: 80A nominal capacity
• Fuse Classification: AC/DC rated fuses with equivalent breaking capacity
• Mounting Type: Stud mount or bolt mount configurations compatible with 80A applications
• Regulatory Compliance: RoHS and REACH status alignment
• Tariff Classification: HTSUS 8536.10.0040 category
• Product Status: Active availability

The identified substitute, Littelfuse part number 154.6631.5802, meets these parameters through equivalent 80A current rating, bolt mount mechanical interface, and matching regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

Selection between the AMI-80 and 154.6631.5802 substitute is determined by application-specific mounting requirements and regulatory environment:

• Both parts maintain Active product status, ensuring continued availability and manufacturing support.
• Both parts comply with RoHS directives (AMI-80: RoHS Compliant; 154.6631.5802: ROHS3 Compliant), suitable for regulated markets.
• Both parts share identical ECCN (EAR99) and HTSUS (8536.10.0040) classifications, enabling equivalent export and tariff treatment.
• Current rating equivalence (80A) ensures electrical performance parity in circuit protection applications.
• Mounting interface difference (stud mount vs. bolt mount) requires mechanical compatibility verification with the target application's terminal configuration.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 154.6631.5802 directly replace the Eaton AMI-80 in all applications?

A: Direct replacement is possible when the application's mechanical mounting interface accommodates bolt mount configuration. Stud mount and bolt mount are distinct mechanical interfaces; physical terminal compatibility must be confirmed before substitution.

Q: Are there electrical performance differences between these 80A fuses?

A: Both parts are rated for 80A current capacity. Specific electrical characteristics such as breaking capacity, melting I²t, and response time (slow blow vs. standard) are provided in detailed specifications and should be cross-referenced with circuit design requirements.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are RoHS compliant and share identical ECCN and HTSUS classifications. The Littelfuse part carries ROHS3 compliance, representing the current RoHS directive iteration. Both are suitable for regulated markets requiring RoHS certification.

Q: What is the difference between stud mount and bolt mount fuses?

A: Stud mount fuses use threaded studs for terminal connection, while bolt mount fuses use bolt holes for mechanical fastening. These are distinct mechanical interfaces and are not interchangeable without terminal adapter hardware.

Q: Is inventory availability a factor in substitution decisions?

A: Inventory levels (AMI-80: 713 pcs; 154.6631.5802: 1460 pcs) reflect current stock status and may influence sourcing decisions based on delivery timeline requirements, but do not affect electrical or mechanical compatibility.
