MDL-1/32 Equivalent & Substitute Parts

Part Overview

The MDL-1/32 is a 31 mA glass cartridge fuse manufactured by Eaton - Electronics Division. This slow-blow fuse is designed for AC/DC applications and requires a 3AB or 3AG holder with dimensions of 1/4" x 1-1/4" (6.35mm x 31.75mm). The part maintains active product status with 985 pieces currently in stock. Substitute parts are identified to provide alternative sourcing options when the primary MDL-1/32 becomes unavailable or when supply chain optimization is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDL-1/32 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 31 mA
• Fuse Type: Cartridge, Glass
• Response Time: Slow Blow
• Package / Case: 3AB, 3AG
• Physical Dimensions: 0.250" Dia x 1.250" L (6.35mm x 31.75mm)
• Mounting Type: Requires Holder

The substitute part 0313.031HXP from Littelfuse Inc. satisfies all mandatory parameters, enabling direct functional equivalence in applications requiring a 31 mA slow-blow glass cartridge fuse with 3AB/3AG holder compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the MDL-1/32 and 0313.031HXP maintain active product status and share identical electrical and mechanical specifications for the 31 mA slow-blow cartridge fuse category. The 0313.031HXP provides additional documented specifications including 250 V AC voltage rating, 35A breaking capacity, and multi-agency approvals (CE, CSA, UL). The substitute part carries ROHS3 compliance and REACH unaffected status, supporting regulatory requirements in regulated markets. Selection between these parts should be based on supply availability, inventory position, and specific application voltage and breaking capacity requirements.

Frequently Asked Questions (FAQ)

Q: Can the 0313.031HXP directly replace the MDL-1/32 in existing applications?

A: Yes. Both parts are 31 mA slow-blow glass cartridge fuses with identical physical dimensions (0.250" Dia x 1.250" L) and package specifications (3AB, 3AG holders). They are mechanically and electrically interchangeable for applications within the specified parameters.

Q: What are the key compatibility factors for this fuse category?

A: Current rating (31 mA), fuse type (cartridge, glass), response time (slow blow), physical dimensions, and holder compatibility (3AB, 3AG) are the critical factors. Both parts match on all these parameters.

Q: Does the 0313.031HXP provide additional certifications?

A: Yes. The 0313.031HXP carries CE, CSA, and UL approvals, whereas the MDL-1/32 does not specify approval agencies. This may be relevant for applications requiring third-party certification documentation.

Q: Are there voltage rating differences between these parts?

A: The MDL-1/32 does not specify a voltage rating in the provided data. The 0313.031HXP is rated for 250 V AC. Verify the application voltage requirement against the 0313.031HXP specification before substitution.

Q: What is the difference in breaking capacity?

A: The 0313.031HXP specifies a breaking capacity of 35A at rated voltage. The MDL-1/32 does not provide this specification. Breaking capacity should be verified against application requirements.

Q: Are both parts RoHS compliant?

A: The 0313.031HXP is ROHS3 compliant. The MDL-1/32 does not specify RoHS status in the provided data. Regulatory compliance requirements should be confirmed for your application.
