Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMG-175 is determined by matching the following critical parameters:

• Current Rating: 175 A (exact match required)
• Voltage Rating - DC: 32 V (exact match required)
• Fuse Type: Automotive (exact match required)
• Mounting Type: Bolt Mount (exact match required)
• Package / Case: Auto Link (exact match required)

The substitute part 154.6395.6172 (Littelfuse Inc., BF2 Series) satisfies all primary electrical and mechanical compatibility criteria. Dimensional variations and enhanced breaking capacity do not preclude functional equivalence in applications where the original AMG-175 is specified.

Parameter Comparison

Engineering Selection Recommendations

Both the AMG-175 and 154.6395.6172 maintain Active product status and meet RoHS compliance requirements. The substitute part 154.6395.6172 provides equivalent electrical performance at the specified 175 A and 32 V DC ratings with identical fuse type, mounting configuration, and package format. The enhanced breaking capacity of 2 kA in the substitute part does not compromise compatibility. Dimensional differences are minor and fall within typical mechanical tolerance ranges for bolt mount automotive fuse applications. Selection between these parts may be based on availability, lead time, or established supply chain preferences.

Frequently Asked Questions (FAQ)

Q: Can 154.6395.6172 be used as a direct replacement for AMG-175?

A: Yes. Both parts share identical current rating (175 A), voltage rating (32 V DC), fuse type (Automotive), mounting type (Bolt Mount), and package format (Auto Link). These parameters define functional equivalence for automotive fuse applications.

Q: What is the significance of the different breaking capacities?

A: The AMG-175 has a breaking capacity of 1 kA, while 154.6395.6172 has 2 kA. A higher breaking capacity indicates the fuse can safely interrupt larger fault currents. This difference does not prevent substitution; the higher capacity of the Littelfuse part provides equivalent or enhanced performance.

Q: Are there dimensional compatibility concerns?

A: Minor dimensional variations exist between the two parts. The AMG-175 measures 1.150" L x 0.606" W x 0.354" H, while 154.6395.6172 measures 1.142" L x 0.740" W x 0.382" H. Both use Auto Link package format and bolt mount configuration. Verify mechanical fit within your specific application enclosure before final selection.

Q: What does "Slow Blow" response time mean for 154.6395.6172?

A: Slow Blow indicates the fuse has a delayed response to overcurrent conditions, allowing brief transient surges to pass without interruption. The AMG-175 does not specify response time in the provided data. Confirm application requirements for transient tolerance before substitution.

Q: Are both parts RoHS compliant?

A: Yes. The AMG-175 is RoHS Compliant, and 154.6395.6172 is ROHS3 Compliant. Both meet environmental compliance standards for electronic component manufacturing and use.
