Key Parameters

Substitute Part Grouping Explanation

Substitution for the 0313008.HXID is determined by strict equivalence across the following electrical and mechanical parameters:

• Current Rating: 8 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Glass
• Response Time: Slow Blow
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4"
• Breaking Capacity @ Rated Voltage: 200 A
• Size / Dimension: 0.250" Dia x 1.250" L (6.35mm x 31.75mm)
• Mounting Type: Requires Holder

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in DC Cold Resistance, Melting I²t, operating temperature range, and approval agencies are secondary parameters that do not affect functional interchangeability within the specified electrical envelope.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring replacement of the obsolete 0313008.HXID, the Littelfuse 313 series variants (0313008.HXIDP, 0313008.HXP, 0313008.MXP, 0313008.VXIDP, 0313008.VXP) are direct functional equivalents with active product status and ROHS3 compliance. These parts maintain identical electrical and mechanical specifications while offering improved regulatory compliance and ongoing availability.

The Eaton MDL-8-R and BK/MDL-8-R fuses provide cross-manufacturer equivalence with the same electrical ratings and package specifications. These alternatives are suitable where multi-source qualification is required or where Eaton components are preferred within the supply chain.

Selection between Littelfuse and Eaton alternatives should be based on existing system qualifications, supply chain preferences, and regulatory requirements specific to the application. All listed substitutes are electrically and mechanically interchangeable within the specified 8 A, 250 V AC/DC operating envelope.

Frequently Asked Questions (FAQ)

Q: Can I use 0313008.HXIDP as a direct replacement for 0313008.HXID?

A: Yes. Both parts share identical electrical ratings (8 A, 250 V AC/DC), response characteristics (Slow Blow), and mechanical dimensions (0.250" Dia x 1.250" L). The primary difference is product status: 0313008.HXID is obsolete while 0313008.HXIDP is active with ROHS3 compliance.

Q: What is the difference between Littelfuse 313 series variants?

A: The Littelfuse variants (0313008.HXIDP, 0313008.HXP, 0313008.MXP, 0313008.VXIDP, 0313008.VXP) maintain identical electrical and mechanical specifications. Differences exist in approval agencies (CE, CSA, K-MARK, PSE, UL combinations) and operating temperature ranges. Selection depends on regional regulatory requirements and application temperature environment.

Q: Are Eaton MDL-8-R fuses compatible with Littelfuse 0313008.HXID?

A: Yes. The Eaton MDL-8-R and BK/MDL-8-R maintain the same current rating (8 A), voltage rating (250 V AC), response time (Slow Blow), package specification (3AB, 3AG, 1/4" x 1-1/4"), and breaking capacity (200 A). DC Cold Resistance differs slightly (0.015 Ohms vs. 0.011 Ohms), but this does not affect functional interchangeability within the specified electrical envelope.

Q: Do all substitute parts fit the same holder?

A: Yes. All listed substitute parts conform to the 3AB and 3AG package specification with dimensions of 0.250" diameter by 1.250" length. They are mechanically interchangeable in any holder designed for this package standard.

Q: Which substitute part should I select for new designs?

A: For new designs, select from the active product status parts: Littelfuse 0313008.HXIDP, 0313008.HXP, 0313008.MXP, 0313008.VXIDP, or 0313008.VXP for Littelfuse sourcing, or Eaton MDL-8-R or BK/MDL-8-R for Eaton sourcing. All maintain long-term availability and regulatory compliance.

Q: What approval agencies certify these fuses?

A: Littelfuse 313 series variants carry CE, CSA, K-MARK, PSE, and UL certifications. Eaton MDL series carries CE, CSA, and UL certifications. Selection should align with regional regulatory requirements for the target application.
