Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0498200.MXT is determined by strict equivalence across the following critical parameters:

• Current Rating: 200 A (exact match required)
• Voltage Rating (DC): 32 V (exact match required)
• Fuse Type: Automotive (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Bolt Mount (exact match required)
• Package / Case: Auto Link (exact match required)
• Breaking Capacity @ Rated Voltage: 1 kA (exact match required)
• Operating Temperature Range: -40°C to 125°C (exact match required)
• Physical Dimensions: 1.614" L × 0.472" W × 0.315" H / 41.00mm × 12.00mm × 8.00mm (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

All substitute part numbers listed below meet these criteria and are manufactured by Littelfuse Inc. within the MIDI® 498 series.

Parameter Comparison

Engineering Selection Recommendations

All four part numbers (0498200.MXT, 0498200.H, 0498200.M, and 0498200.MXTM6) are electrically and mechanically equivalent within the MIDI® 498 automotive fuse series and maintain active product status. Selection among these alternatives is based on the following factors:

Compliance and Certification: Part 0498200.M carries UL approval agency certification, while 0498200.MXT, 0498200.H, and 0498200.MXTM6 do not list approval agency designation. Applications requiring UL-certified components should specify 0498200.M.

DC Cold Resistance: Part 0498200.M specifies 0.00025 Ohms, while 0498200.MXT, 0498200.H, and 0498200.MXTM6 specify 0.000261 Ohms. This minor variance does not affect functional equivalence for automotive protection applications.

Inventory Availability: Part 0498200.M offers the highest current inventory at 3,232 units, followed by 0498200.MXT at 2,139 units, 0498200.H at 1,022 units, and 0498200.MXTM6 at 837 units.

All parts are ROHS3 compliant and suitable for direct substitution in automotive electrical protection circuits rated for 200A at 32VDC with slow-blow response characteristics.

Frequently Asked Questions (FAQ)

Q: Can 0498200.H be used as a direct replacement for 0498200.MXT?

A: Yes. Both parts meet identical electrical specifications (200A, 32VDC, slow-blow response, 1kA breaking capacity) and mechanical requirements (bolt mount, Auto Link package, 41.00mm × 12.00mm × 8.00mm dimensions). The parts are functionally equivalent for automotive fuse applications.

Q: What is the difference between 0498200.M and 0498200.MXT?

A: The primary difference is UL approval agency certification on 0498200.M. Both parts share identical current rating, voltage rating, response time, mounting type, package style, and physical dimensions. DC cold resistance differs marginally (0.00025 Ohms vs. 0.000261 Ohms). Applications requiring UL certification must use 0498200.M.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All four part numbers (0498200.MXT, 0498200.H, 0498200.M, and 0498200.MXTM6) are ROHS3 compliant and suitable for applications with environmental compliance requirements.

Q: Can these fuses be used interchangeably in the same circuit?

A: Yes. All substitute parts maintain identical electrical characteristics (200A current rating, 32VDC voltage rating, slow-blow response, 1kA breaking capacity) and physical dimensions. They are mechanically and electrically interchangeable for bolt mount Auto Link installations.

Q: Which part number should be selected for highest inventory availability?

A: Part 0498200.M offers the highest current inventory at 3,232 units. If supply continuity is a priority, this part number is recommended.

Q: Do these fuses require any special installation considerations?

A: All parts use identical bolt mount installation and Auto Link packaging. No special installation procedures are required when substituting between these part numbers. Physical dimensions and mounting interfaces are identical across all four alternatives.
