Substitute Part Grouping Explanation

Substitution eligibility for the AMXL-80 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Current Rating: 80 A (exact match required)
• Voltage Rating - DC: 125 V (exact match required)
• Breaking Capacity @ Rated Voltage: 3 kA (exact match required)
• DC Cold Resistance: 0.00051 Ohms (exact match required)

Mechanical Specifications:

• Mounting Type: Bolt Mount (exact match required)
• Package / Case: Auto Link (exact match required)
• Physical Dimensions: 0.630" L x 0.472" W x 0.335" H / 16.00 mm x 12.00 mm x 8.50 mm (exact match required)

Regulatory & Environmental:

• Approval Agency: cURus, UL (exact match required)
• Operating Temperature Range: -40°C ~ 105°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Fuse Classification:

• Fuse Type: Automotive (exact match required)

Substitute parts must satisfy all parameters listed above to ensure functional and mechanical interchangeability without circuit redesign or mechanical modification.

Parameter Comparison

Engineering Selection Recommendations

The AMX-80 is a parametric equivalent to the AMXL-80 based on matching electrical ratings, mechanical specifications, and regulatory certifications. Both parts are manufactured by Eaton - Electronics Division and maintain Active product status with current inventory availability.

Selection Criteria:

1. Electrical Compatibility: Both parts deliver identical current protection at 80 A with 125 V DC rating and 3 kA breaking capacity, ensuring equivalent circuit protection performance.

2. Mechanical Interchangeability: Identical bolt mount configuration, Auto Link package format, and physical dimensions (16.00 mm x 12.00 mm x 8.50 mm) enable direct mechanical substitution without enclosure or mounting modification.

3. Regulatory Compliance: Both parts carry cURus and UL approvals and maintain ROHS3 compliance, satisfying automotive and environmental regulatory requirements.

4. Thermal Performance: Matching operating temperature range (-40°C ~ 105°C) and DC cold resistance (0.00051 Ohms) confirm equivalent thermal and electrical behavior across specified operating conditions.

5. Inventory Availability: AMXL-80 (814 units) and AMX-80 (705 units) are both in stock, providing supply flexibility for production requirements.

Frequently Asked Questions (FAQ)

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

A: Yes. The AMX-80 meets all electrical, mechanical, and regulatory parameters required for functional equivalence. Both parts deliver 80 A protection at 125 V DC with identical breaking capacity, mounting configuration, and physical dimensions.

Q: Are there differences between AMXL-80 and AMX-80 beyond the part number?

A: The parts differ in series designation (AMXL versus AMX) but are parametrically equivalent across all functional specifications. Both are manufactured by Eaton - Electronics Division and carry identical electrical ratings, mechanical specifications, and regulatory certifications.

Q: Will the AMX-80 fit in the same mounting location as the AMXL-80?

A: Yes. Both parts feature bolt mount installation and identical physical dimensions (0.630" L x 0.472" W x 0.335" H). No mechanical modification or enclosure redesign is required for substitution.

Q: Do both parts meet the same regulatory standards?

A: Yes. AMXL-80 and AMX-80 both carry cURus and UL approvals and maintain ROHS3 compliance, satisfying automotive and environmental regulatory requirements.

Q: What is the DC cold resistance specification, and why is it important?

A: Both parts specify 0.00051 Ohms DC cold resistance. This parameter defines the electrical resistance of the fuse element at room temperature and directly affects voltage drop and thermal performance in the circuit. Matching values ensure equivalent electrical behavior.

Q: Are both parts currently available for procurement?

A: Yes. AMXL-80 has 814 units in stock and AMX-80 has 705 units in stock, both listed as new original inventory from Eaton - Electronics Division.

Q: What is the breaking capacity specification?

A: Both parts specify 3 kA breaking capacity at rated voltage (125 V DC). This parameter defines the maximum fault current the fuse can safely interrupt without component failure or hazard.

Q: Can these fuses operate across the full temperature range in automotive environments?

A: Yes. Both AMXL-80 and AMX-80 are rated for -40°C ~ 105°C operation, covering automotive ambient and engine compartment temperature extremes.
