Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0498100.MXM6 are qualified based on the following critical parameters that determine functional equivalence:

Matching Parameters:

• Current Rating: 100 A (exact match required)
• Fuse Type: Automotive (exact match required)
• Mounting Type: Bolt Mount (exact match required)
• Package / Case: Auto Link (exact match required)

Allowable Variations:

• Voltage Rating - DC: Substitute parts rated at 125 V DC are acceptable for applications originally specified at 32 V DC, as higher voltage rating provides enhanced safety margin
• Breaking Capacity: Substitute parts with 3 kA breaking capacity exceed the 1 kA requirement, providing improved fault protection
• Manufacturer: Alternative qualified manufacturers (Eaton - Electronics Division) are acceptable when electrical and mechanical specifications align
• Packaging Format: Bulk, Box, or Tray packaging formats are interchangeable for procurement purposes

The identified substitutes (AMX-100 and BK-AMX-100) maintain all critical electrical and mechanical parameters while offering alternative sourcing options.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (0498100.MXM6): Select the Littelfuse 0498100.MXM6 when the original specification requires MIDI® 498 series components or when the 32 V DC voltage rating is a critical design parameter. This part maintains active product status with established UL approval and ROHS3 compliance.

Substitute Selection (AMX-100 or BK-AMX-100): The Eaton AMX-100 and BK-AMX-100 are functionally equivalent substitutes when:

• The application circuit can accommodate the higher 125 V DC voltage rating
• The 3 kA breaking capacity meets or exceeds circuit protection requirements
• Eaton series components are acceptable within the design specification
• Both parts maintain cURus and UL approvals with ROHS3 compliance

Packaging Consideration:

• AMX-100: Box packaging format
• BK-AMX-100: Tray packaging format

Both substitute parts are electrically and mechanically interchangeable with the original part. Selection between AMX-100 and BK-AMX-100 depends on procurement and inventory management requirements.

Frequently Asked Questions (FAQ)

Q: Can AMX-100 or BK-AMX-100 be used in place of 0498100.MXM6?

A: Yes. Both Eaton substitutes maintain the required 100 A current rating, automotive fuse type, bolt mount installation, and auto link packaging. The higher 125 V DC rating and 3 kA breaking capacity provide enhanced electrical performance margins. Both parts carry UL and cURus approvals with ROHS3 compliance.

Q: What is the difference between AMX-100 and BK-AMX-100?

A: Both parts are electrically and mechanically identical. The difference is packaging format: AMX-100 is supplied in Box packaging, while BK-AMX-100 is supplied in Tray packaging. Selection depends on procurement volume and inventory handling requirements.

Q: Why do the substitute parts have a higher voltage rating (125 V DC vs. 32 V DC)?

A: Higher voltage rating indicates the fuse can safely operate in circuits with higher voltage potential. A 125 V DC rated fuse is suitable for 32 V DC applications, as it provides additional safety margin. The fuse will operate identically at the lower voltage.

Q: Are there any temperature operating range differences?

A: The original 0498100.MXM6 operates from -40°C to 125°C, while substitute parts (AMX-100 and BK-AMX-100) operate from -40°C to 105°C. For applications requiring operation above 105°C, the original Littelfuse part is required.

Q: Do all three parts have the same approval certifications?

A: The original 0498100.MXM6 carries UL approval. Both substitute parts (AMX-100 and BK-AMX-100) carry cURus and UL approvals, providing broader regulatory acceptance. All three parts are ROHS3 compliant.

Q: What does the higher breaking capacity (3 kA vs. 1 kA) mean?

A: Breaking capacity indicates the maximum fault current the fuse can safely interrupt. The substitute parts with 3 kA breaking capacity can handle higher fault currents than the original 1 kA specification, providing enhanced protection in high-fault-current circuits.
