Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0498030.H is determined by strict equivalence across the following critical parameters:

• Current Rating: 30 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)
• Physical Dimensions: 1.614" L x 0.472" W x 0.315" H / 41.00mm x 12.00mm x 8.00mm (exact match required)
• Operating Temperature Range: -40°C ~ 125°C (exact match required)
• Series: MIDI® 498 (exact match required)

All four substitute parts (0498030.M, 0498030.MX1M6, 0498030.MXT, 0498030.TXN) meet these criteria and are classified as parametric equivalents within the MIDI® 498 automotive fuse family.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and full RoHS3 compliance. Selection between 0498030.H and its equivalents should be based on the following factors:

Approval Agency Certification: Part 0498030.M carries UL approval, while 0498030.MX1M6 carries UR approval. The 0498030.H, 0498030.MXT, and 0498030.TXN do not list approval agency designation. Applications requiring specific third-party certification should reference the approval agency requirement.

DC Cold Resistance: The 0498030.M exhibits a DC cold resistance of 0.0021 Ohms, while 0498030.H, 0498030.MX1M6, 0498030.MXT, and 0498030.TXN all measure 0.00206 Ohms. This minor variance remains within functional equivalence for automotive circuit protection applications.

Color Designation: The 0498030.H carries no color designation. Substitute parts 0498030.MX1M6, 0498030.MXT, and 0498030.TXN are designated Orange. Color coding may be relevant for circuit identification or documentation purposes in specific automotive platforms.

Inventory Availability: Current stock levels vary across the substitute group, with 0498030.MXT maintaining the highest inventory (1621 Pcs), followed by 0498030.M (1525 Pcs), 0498030.H (854 Pcs), 0498030.MX1M6 (807 Pcs), and 0498030.TXN (706 Pcs).

Frequently Asked Questions (FAQ)

Q: Can 0498030.M be used as a direct replacement for 0498030.H?

A: Yes. Both parts are parametric equivalents with identical current rating (30A), voltage rating (32VDC), response time (Slow Blow), mounting type (Bolt Mount), package configuration (Auto Link), and physical dimensions. The primary difference is UL approval certification on 0498030.M. If UL certification is required by application specifications, 0498030.M is the appropriate selection.

Q: What is the significance of the color designation on substitute parts?

A: Color designation (Orange on 0498030.MX1M6, 0498030.MXT, and 0498030.TXN) is a visual identifier used in automotive wiring harnesses and circuit documentation. If the original circuit design specifies a particular color code, the color-designated substitute should be selected to maintain consistency with existing documentation and assembly procedures.

Q: Are there any electrical performance differences between the substitute parts?

A: All substitute parts maintain identical electrical specifications: 30A current rating, 32VDC voltage rating, 1kA breaking capacity, and -40°C to 125°C operating temperature range. DC cold resistance values are functionally equivalent (0.00206 Ohms for most parts, 0.0021 Ohms for 0498030.M), with negligible impact on circuit performance.

Q: Which substitute part should be selected for applications requiring third-party certification?

A: For UL-certified applications, select 0498030.M. For UR-certified applications, select 0498030.MX1M6. If no specific certification requirement exists, any substitute part meets the functional and compliance requirements of the MIDI® 498 automotive fuse platform.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All parts in this equivalence group (0498030.H, 0498030.M, 0498030.MX1M6, 0498030.MXT, 0498030.TXN) are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for automotive component applications.
