Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MDL-8/10-R are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Current Rating: 800 mA
• Voltage Rating (AC): 250 V
• Response Time: Slow Blow
• Fuse Type: Cartridge, Glass
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4"
• Physical Dimensions: 0.250" Dia x 1.250" L (6.35mm x 31.75mm)

All identified substitute parts meet these core requirements. Substitution is valid when these parameters align with the original specification, ensuring mechanical fit in existing fuse holders and electrical performance in the circuit application.

Parameter Comparison

Engineering Selection Recommendations

BK/MDL-8/10-R (Eaton - Electronics Division): This part is a parametric equivalent from the same manufacturer as the primary part. It maintains Active product status and ROHS3 compliance. Inventory availability is 1372 pieces. This substitute is suitable for direct replacement in applications requiring continuity with Eaton product lines.

0034.5224 (SCHURTER Inc.): This part meets all electrical and mechanical specifications. However, it carries Obsolete product status, indicating discontinued production. While 766 pieces are currently in stock, long-term availability cannot be assured. This substitute is suitable only for immediate replacement needs where existing inventory is available.

0313.800MXP (Littelfuse Inc.): This part is a parametric equivalent with Active product status and ROHS3 compliance. It offers the highest current inventory level at 1916 pieces. This substitute is suitable for applications where cross-manufacturer compatibility is acceptable and long-term supply continuity is required.

Frequently Asked Questions (FAQ)

Q: Can BK/MDL-8/10-R be used as a direct replacement for MDL-8/10-R? A: Yes. Both parts are manufactured by Eaton - Electronics Division and share identical electrical ratings (800 mA, 250 V AC), response time (Slow Blow), fuse type (Cartridge, Glass), and physical dimensions (0.250" Dia x 1.250" L). They are mechanically and electrically interchangeable.

Q: Why is 0034.5224 marked as Obsolete? A: The 0034.5224 is a SCHURTER Inc. product that has been discontinued by the manufacturer. While current inventory exists, future availability is not guaranteed. This part should be used only when immediate replacement is necessary and other active alternatives are unavailable.

Q: Is 0313.800MXP compatible with existing 3AB and 3AG fuse holders? A: Yes. The 0313.800MXP maintains the same physical dimensions (0.250" Dia x 1.250" L) and package designation (3AB, 3AG, 1/4" x 1-1/4") as the MDL-8/10-R, ensuring mechanical compatibility with standard fuse holders.

Q: What are the key parameters that determine substitution eligibility? A: Substitution is determined by matching: Current Rating (800 mA), Voltage Rating - AC (250 V), Response Time (Slow Blow), Fuse Type (Cartridge, Glass), Package / Case (3AB, 3AG, 1/4" x 1-1/4"), and physical dimensions (0.250" Dia x 1.250" L). All identified substitutes meet these criteria.

Q: Are all substitute parts RoHS compliant? A: Yes. All substitute parts listed carry ROHS3 compliance status, meeting current environmental and regulatory requirements.

Q: Which substitute offers the best long-term supply availability? A: The 0313.800MXP from Littelfuse Inc. maintains Active product status with the highest inventory level (1916 pieces), providing the strongest assurance of continued availability.
