MDL-6/10-R Equivalent & Substitute Parts Reference

Part Overview

The MDL-6/10-R is a 600 mA, 250 V AC/DC glass cartridge fuse manufactured by Eaton - Electronics Division. This slow-blow fuse is designed for 3AB and 3AG holder applications with dimensions of 1/4" x 1-1/4" (6.35mm x 31.75mm). The part is currently active in production and RoHS compliant. Equivalent substitute parts are necessary when primary inventory is unavailable, when sourcing from alternative manufacturers is required for supply chain optimization, or when specific compliance certifications are mandated by application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDL-6/10-R is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 600 mA
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Glass
• Response Time: Slow Blow
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4"
• Size / Dimension: 0.250" Dia x 1.250" L (6.35mm x 31.75mm)
• Mounting Type: Requires Holder

All identified substitute parts meet these mandatory parameters without exception. Variations in secondary parameters such as breaking capacity, melting I²t, approval agencies, and operating temperature ranges do not affect functional interchangeability within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status):

BK/MDL-6/10-R, 0313.600HXP, and 0313.600MXP are all active products from established manufacturers. BK/MDL-6/10-R is manufactured by Eaton - Electronics Division, the original equipment manufacturer, and carries ROHS3 compliance. The Littelfuse parts (0313.600HXP and 0313.600MXP) are active alternatives with CE, CSA, and UL certifications, providing multi-agency approval coverage.

Secondary Substitute (Obsolete Status):

0034.5220 from SCHURTER Inc. is classified as obsolete. While it meets all mandatory electrical and mechanical parameters, its discontinued status limits long-term availability and future support. This part is suitable only for immediate replacement needs where existing inventory exists.

Compliance Considerations:

All substitute parts are ROHS3 compliant and REACH unaffected. The Littelfuse alternatives (0313.600HXP and 0313.600MXP) provide broader approval agency coverage (CE, CSA, UL) compared to the Eaton variants, which may be advantageous for applications requiring multi-regional certification documentation.

Frequently Asked Questions (FAQ)

Q: Can 0313.600MXP be used as a direct replacement for MDL-6/10-R?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical current rating (600 mA), voltage rating (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). Both are active products with current production status and ROHS3 compliance.

Q: What is the difference between 0313.600HXP and 0313.600MXP?

A: Both parts are manufactured by Littelfuse Inc. and are electrically and mechanically identical. They share the same current rating, voltage rating, fuse type, response time, package, and dimensions. Both are active products with identical compliance certifications (CE, CSA, UL, ROHS3). Selection between these two parts may be based on inventory availability or specific application documentation requirements.

Q: Why is 0034.5220 listed as obsolete?

A: The 0034.5220 from SCHURTER Inc. is marked as obsolete in the manufacturer's product lifecycle status. While it remains electrically and mechanically equivalent to MDL-6/10-R, its discontinued status indicates that new production has ceased. Existing inventory may be available from authorized distributors, but long-term supply cannot be guaranteed.

Q: Are all substitute parts compatible with 3AB and 3AG holders?

A: Yes. All substitute parts are specified for 3AB and 3AG holder applications with identical physical dimensions of 0.250" Dia x 1.250" L (6.35mm x 31.75mm). Physical interchangeability is guaranteed across all listed alternatives.

Q: What approval agencies certify these fuse products?

A: The Eaton MDL-6/10-R and BK/MDL-6/10-R do not list specific approval agencies in the provided data. The SCHURTER 0034.5220 carries CSA and UL certifications. The Littelfuse alternatives (0313.600HXP and 0313.600MXP) carry CE, CSA, and UL certifications, providing the broadest regulatory coverage among all listed parts.
