Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MDL-V-1-1/2-R are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following critical parameters:

Electrical Parameters:

• Current Rating: 1.5 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Breaking Capacity: 100 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 (minimum requirement)
• RoHS Status: RoHS Compliant or ROHS3 Compliant (acceptable)

All identified substitutes meet these criteria and are therefore electrically and mechanically interchangeable with the MDL-V-1-1/2-R in circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can BK/MDL-V-1-1/2-R be used as a direct replacement for MDL-V-1-1/2-R?

A: Yes. The BK/MDL-V-1-1/2-R is a parametric equivalent with identical electrical and mechanical specifications. Both parts are manufactured by Eaton - Electronics Division and share the same current rating (1.5 A), voltage rating (250 V), fuse type (Cartridge, Glass), response time (Slow Blow), package format (3AB, 3AG, 1/4" x 1-1/4"), and breaking capacity (100 A). Direct substitution is supported.

Q: What is the difference between the Eaton MDL-V-1-1/2-R and the Littelfuse 031501.5HXP/031501.5MXP?

A: The primary differences are manufacturer and minor physical dimensions. The Littelfuse parts (031501.5HXP and 031501.5MXP) have a slightly larger diameter (0.275" vs. 0.266") and slightly shorter length (1.275" vs. 1.292"), though both conform to the 3AB, 3AG package specification. The Littelfuse parts include PSE certification in addition to CE, CSA, and UL. The Littelfuse parts also specify an operating temperature range of -55°C ~ 125°C, whereas the Eaton part does not specify an operating temperature range. All other electrical parameters are identical.

Q: Are the Littelfuse 031501.5HXP and 031501.5MXP interchangeable with each other?

A: Yes. Both Littelfuse parts share identical electrical and mechanical specifications, including current rating, voltage rating, fuse type, response time, package format, and breaking capacity. Both carry the same certifications (CE, CSA, PSE, UL) and maintain Active product status. The parts are interchangeable.

Q: What certifications do these fuses carry?

A: The MDL-V-1-1/2-R and BK/MDL-V-1-1/2-R carry CE, CSA, and UL certifications. The Littelfuse 031501.5HXP and 031501.5MXP carry CE, CSA, PSE, and UL certifications. All parts meet the minimum approval agency requirements for circuit protection applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. The MDL-V-1-1/2-R is RoHS Compliant. The BK/MDL-V-1-1/2-R, 031501.5HXP, and 031501.5MXP are all ROHS3 Compliant, which represents an updated compliance standard. All parts meet RoHS requirements.

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

A: Yes. All parts are rated for 1.5 A at 250 V AC/DC, indicating compatibility with both alternating current and direct current applications within the specified voltage and current limits.

Q: What is the significance of the "Slow Blow" response time?

A: Slow Blow response time indicates that these fuses are designed to tolerate temporary current surges without immediate rupture, while still providing protection against sustained overcurrent conditions. This characteristic is essential for applications with inrush currents or temporary load spikes.
