MDL-V-5-R Equivalent & Substitute Parts

Part Overview

The MDL-V-5-R is a 5 A, 250 V AC/DC slow-blow glass cartridge fuse manufactured by Eaton - Electronics Division. This through-hole fuse is designed for general-purpose circuit protection in applications requiring moderate current ratings and slow-blow response characteristics. The part is actively produced and maintained in inventory, with 1011 pieces currently available in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component substitution within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MDL-V-5-R is permissible with parts that maintain electrical and mechanical compatibility across the following critical parameters:

Electrical Parameters:

• Current Rating: 5 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 200 A (exact match required)

Mechanical Parameters:

• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)

Compliance Parameters:

• Approval Agencies: CE, CSA, UL certifications required
• RoHS Status: RoHS Compliant or equivalent

The substitute part 0315005.HXP manufactured by Littelfuse Inc. satisfies all critical electrical, mechanical, and compliance requirements for direct substitution with the MDL-V-5-R.

Parameter Comparison

Engineering Selection Recommendations

Both the MDL-V-5-R and 0315005.HXP are active products with full regulatory compliance. The MDL-V-5-R is manufactured by Eaton - Electronics Division and holds CE, CSA, and UL certifications. The 0315005.HXP substitute is manufactured by Littelfuse Inc. and holds CE, CSA, K-MARK, PSE, and UL certifications, providing broader international approval coverage.

Selection between these parts should be based on:

1. Availability: MDL-V-5-R has 1011 pieces in stock; 0315005.HXP has 1068 pieces in stock.
2. Regulatory Requirements: Both parts meet CE, CSA, and UL standards. The 0315005.HXP provides additional K-MARK and PSE certifications for applications requiring broader international compliance.
3. RoHS Compliance: MDL-V-5-R is RoHS Compliant; 0315005.HXP is ROHS3 Compliant, representing a more recent compliance standard.
4. Physical Dimensions: Dimensional tolerances between parts are within typical manufacturing specifications for 3AB/3AG cartridge fuses. Both parts are mechanically compatible with standard through-hole fuse holders.

Frequently Asked Questions (FAQ)

Q: Can the 0315005.HXP be used as a direct replacement for the MDL-V-5-R?

A: Yes. Both parts share identical electrical ratings (5 A, 250 V AC), response time (Slow Blow), fuse type (Cartridge, Glass), package designation (3AB, 3AG), and breaking capacity (200 A). Both are through-hole mounted and hold the required CE, CSA, and UL certifications.

Q: What are the differences in melting I²t values between these parts?

A: The MDL-V-5-R has a melting I²t of 32, while the 0315005.HXP has a melting I²t of 140. Both values fall within the acceptable range for 5 A slow-blow fuses and do not affect substitution eligibility for applications designed to the specified 5 A, 250 V rating.

Q: Are there dimensional compatibility concerns?

A: The MDL-V-5-R measures 0.266" Dia x 1.292" L (6.76mm x 32.82mm), while the 0315005.HXP measures 0.275" Dia x 1.275" L (6.99mm x 32.39mm). Both dimensions conform to 3AB/3AG cartridge fuse standards and are compatible with standard through-hole fuse holders designed for this package type.

Q: Does the operating temperature specification affect substitution?

A: The MDL-V-5-R does not specify an operating temperature range. The 0315005.HXP specifies -55°C ~ 125°C. For applications operating within standard industrial temperature ranges, both parts are suitable. Applications requiring operation outside the specified range for the 0315005.HXP should reference the MDL-V-5-R datasheet for temperature specifications.

Q: What is the difference in DC cold resistance?

A: The MDL-V-5-R has a DC cold resistance of 0.025 Ohms, while the 0315005.HXP has 0.0214 Ohms. This minor difference does not affect circuit protection performance at the specified 5 A rating and does not preclude substitution.

Q: Are both parts RoHS compliant?

A: Yes. The MDL-V-5-R is RoHS Compliant, and the 0315005.HXP is ROHS3 Compliant. Both meet current RoHS requirements for electronic components.
