Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MDL-2-8/10-R are qualified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Parameters for Substitution:

• Current Rating: 2.8 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Physical Dimensions: 0.250" Dia x 1.250" L (exact match required)

All identified substitute parts meet these mandatory parameters. Substitute parts may differ in manufacturer, series designation, inventory availability, and optional certifications or performance specifications not required for basic functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MDL-2-8/10-R, BK/MDL-2-8/10-R, and 031302.8HXP—are active products with full electrical and mechanical equivalence. Selection among these parts may be based on the following factors:

Manufacturer Continuity: The BK/MDL-2-8/10-R maintains the same manufacturer (Eaton - Electronics Division) as the primary part, supporting supply chain consistency and design standardization within Eaton product families.

Certification Coverage: The 031302.8HXP (Littelfuse) carries expanded approval agency certifications including CE, CSA, K-MARK, PSE, and UL, providing broader regulatory compliance documentation for applications requiring multi-region certification.

Inventory Availability: All three parts maintain adequate stock levels (900–940 pieces), ensuring procurement flexibility without extended lead times.

RoHS Compliance: Both Eaton parts are RoHS Compliant; the Littelfuse part is ROHS3 Compliant, meeting current and future environmental regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can BK/MDL-2-8/10-R be used as a direct replacement for MDL-2-8/10-R?

A: Yes. Both parts are manufactured by Eaton - Electronics Division and share identical electrical ratings (2.8 A, 250 V AC), fuse type (Cartridge, Glass), response time (Slow Blow), package designation (3AB, 3AG), and physical dimensions (0.250" Dia x 1.250" L). They are functionally equivalent for all applications.

Q: Is the Littelfuse 031302.8HXP compatible with the same holder as the Eaton MDL-2-8/10-R?

A: Yes. The 031302.8HXP conforms to the same 3AB and 3AG holder standards and has identical physical dimensions (0.250" Dia x 1.250" L). It is mechanically and electrically compatible with any holder designed for the MDL-2-8/10-R.

Q: What are the key differences between these substitute parts?

A: The primary differences are manufacturer identity and optional certifications. The Littelfuse 031302.8HXP provides additional performance specifications (Breaking Capacity @ 100 A, Melting I²t of 170, DC Cold Resistance of 0.0675 Ohms) and broader approval agency certifications (CE, CSA, K-MARK, PSE, UL). All three parts meet the core electrical and mechanical requirements for 2.8 A, 250 V AC slow-blow cartridge fuse applications.

Q: Are all three parts RoHS compliant?

A: Yes. The MDL-2-8/10-R and BK/MDL-2-8/10-R are RoHS Compliant. The 031302.8HXP is ROHS3 Compliant, which represents the current and future standard for RoHS compliance.

Q: Can these parts be used interchangeably in production?

A: Yes, provided the application does not specify a particular manufacturer or series. All three parts meet identical electrical specifications, mechanical dimensions, and holder compatibility requirements. Design documentation should specify the acceptable part numbers to ensure procurement flexibility.
