Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMG-300 is determined by the following critical parameters:

• Current Rating: 300 A (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Mounting Type: Bolt Mount (exact match required)
• Fuse Type: Automotive (exact match required)
• Package / Case: Auto Link (exact match required)

The substitute part 154.6395.6302 (Littelfuse Inc., BF2 series) meets all mandatory electrical and mechanical compatibility criteria. Dimensional variations and enhanced breaking capacity do not preclude substitution when core electrical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both the AMG-300 and 154.6395.6302 maintain Active product status and meet RoHS compliance requirements. The Littelfuse 154.6395.6302 provides equivalent electrical performance with enhanced breaking capacity (2 kA versus 1 kA) and ROHS3 certification. Dimensional differences are minor and do not affect bolt mount compatibility. Selection between these parts should be based on application-specific requirements, inventory availability, and design validation protocols.

Frequently Asked Questions (FAQ)

Q: Can the 154.6395.6302 directly replace the AMG-300 in existing designs?

A: Yes, when current rating (300 A), voltage rating (32 V DC), mounting type (Bolt Mount), fuse type (Automotive), and package type (Auto Link) are the primary selection criteria. Dimensional variations are within acceptable tolerance for bolt mount applications.

Q: What is the significance of the Slow Blow response time on the Littelfuse part?

A: Response time characterizes fuse melting behavior under overcurrent conditions. The Slow Blow characteristic of the 154.6395.6302 indicates delayed response to transient overcurrents, which may be advantageous in circuits with inrush current profiles.

Q: Are there compliance differences between the two parts?

A: Both parts are RoHS compliant. The Littelfuse part carries ROHS3 certification, representing the current RoHS standard. Both parts are classified as EAR99 for export control purposes.

Q: How do the breaking capacity ratings differ?

A: The AMG-300 has a breaking capacity of 1 kA at rated voltage, while the 154.6395.6302 has 2 kA. Higher breaking capacity indicates greater ability to safely interrupt fault currents without component damage.

Q: Are dimensional differences critical for Auto Link package compatibility?

A: Dimensional variations between the two parts are minor (approximately 0.008" in length, 0.134" in width, 0.028" in height). Bolt mount applications typically accommodate these tolerances. Physical fit verification in the specific mounting location is recommended during design validation.
