Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMX-80 are identified through parametric equivalence matching. The substitution logic is based on the following critical parameters that must remain constant across all equivalent components:

• Current Rating: 80 A
• Voltage Rating - DC: 125 V
• Fuse Type: Automotive
• Mounting Type: Bolt Mount
• Package / Case: Auto Link
• Breaking Capacity @ Rated Voltage: 3 kA
• Operating Temperature Range: -40°C ~ 105°C
• Physical Dimensions: 0.630" L x 0.472" W x 0.335" H
• DC Cold Resistance: 0.00051 Ohms
• Regulatory Compliance: cURus, UL certifications
• Environmental Compliance: ROHS3 Compliant

Parts meeting all these specifications are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the AMX-80 and AMXL-80 are Active status products manufactured by Eaton - Electronics Division with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and supply chain considerations. Both components carry cURus and UL regulatory approvals and maintain ROHS3 compliance, confirming suitability for automotive circuit protection applications across the specified operating temperature range of -40°C to 105°C. The matching DC cold resistance of 0.00051 Ohms and identical breaking capacity of 3 kA ensure equivalent performance in high-current fault conditions.

Frequently Asked Questions (FAQ)

Q: Can AMXL-80 be used as a direct replacement for AMX-80?

A: Yes. The AMXL-80 is a parametric equivalent with identical current rating (80 A), voltage rating (125 V DC), fuse type (Automotive), mounting configuration (Bolt Mount), package type (Auto Link), breaking capacity (3 kA), operating temperature range (-40°C ~ 105°C), physical dimensions, and regulatory certifications (cURus, UL). Direct substitution is supported.

Q: Are there any differences in the physical mounting between AMX-80 and AMXL-80?

A: No. Both parts feature identical bolt mount configuration and Auto Link package type with matching dimensions of 0.630" L x 0.472" W x 0.335" H (16.00mm x 12.00mm x 8.50mm). Mechanical interchangeability is confirmed.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both AMX-80 and AMXL-80 carry cURus and UL approvals and are ROHS3 compliant, meeting identical regulatory requirements for automotive applications.

Q: What is the significance of the 0.00051 Ohms DC cold resistance specification?

A: DC cold resistance is a critical parameter for fuse performance under normal operating conditions. Both parts maintain identical resistance, ensuring equivalent voltage drop and thermal characteristics in the circuit.

Q: Can these fuses be used in applications outside the -40°C to 105°C temperature range?

A: No. Both parts are specified for operation within -40°C to 105°C. Use outside this range is not supported by the provided specifications.
