Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MDL-V-2-R are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic requires exact matching of the following criteria:

• Current Rating: 2 A (no tolerance variation)
• Voltage Rating (AC): 250 V (no tolerance variation)
• Fuse Type: Cartridge, Glass (identical construction)
• Response Time: Slow Blow (identical thermal response)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (identical form factor and dimensions)
• Mounting Type: Through Hole (identical installation method)
• Breaking Capacity @ Rated Voltage: 100 A (identical interrupting rating)
• DC Cold Resistance: 0.116 Ohms (identical electrical characteristic)
• Melting I²t: 62.3 (identical thermal energy rating)
• Approval Agency: CE, CSA, UL (identical regulatory compliance)

Only parts meeting all these parameters are classified as direct substitutes. Variations in any parameter disqualify a part from this equivalence group.

Parameter Comparison

Engineering Selection Recommendations

Both MDL-V-2-R and BK/MDL-V-2-R are functionally equivalent and maintain Active product status. Selection between these parts is based on the following engineering considerations:

MDL-V-2-R: Suitable for applications where standard RoHS compliance is required. Current inventory: 798 pieces.

BK/MDL-V-2-R: Suitable for applications requiring ROHS3 compliance and REACH unaffected status. This variant provides enhanced regulatory alignment for markets with stricter environmental requirements. Current inventory: 1050 pieces.

Both parts carry identical CE, CSA, and UL approvals, ensuring regulatory acceptance in equivalent application contexts. The choice between variants depends on specific compliance mandates of the end application and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can BK/MDL-V-2-R be used as a direct replacement for MDL-V-2-R in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters: 2 A current rating, 250 V AC voltage rating, slow blow response, 3AB/3AG package, 100 A breaking capacity, and 0.116 Ohms DC cold resistance. The BK variant offers enhanced RoHS3 compliance.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 represents a more recent iteration of RoHS compliance standards. Both variants meet RoHS requirements; ROHS3 indicates compliance with the latest regulatory framework. Selection depends on application-specific compliance requirements.

Q: Are the physical dimensions identical between MDL-V-2-R and BK/MDL-V-2-R?

A: Yes. Both parts share identical dimensions of 0.266" diameter x 1.292" length (6.76mm x 32.82mm) and are packaged in the 3AB, 3AG, 1/4" x 1-1/4" form factor for through-hole mounting.

Q: Do both parts carry the same regulatory approvals?

A: Yes. Both MDL-V-2-R and BK/MDL-V-2-R carry CE, CSA, and UL approvals, ensuring equivalent regulatory acceptance.

Q: What is the melting I²t value, and why is it important for substitution?

A: The melting I²t value of 62.3 represents the thermal energy required to melt the fuse element. This parameter must be identical between substitute parts to ensure equivalent protection characteristics and response behavior in circuit protection applications.

Q: Can these fuses be used in both AC and DC applications?

A: Yes. Both parts are rated for 250 V AC/DC operation, providing flexibility for use in alternating current and direct current circuits within the specified voltage range.
