Key Parameters

Substitute Part Grouping Explanation

Substitution of the MDL-1/10-R is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Current Rating: 100 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 35A (exact match required)

Mechanical Parameters:

• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Size / Dimension: 0.250" Dia x 1.250" L (exact match required)
• Mounting Type: Requires Holder (exact match required)

Compliance Parameters:

• Approval Agency: CE, CSA, UL (all certifications present)

All substitute parts listed below meet these criteria without exception. Substitutes are grouped by manufacturer and part number designation.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the MDL-1/10-R and meet identical electrical, mechanical, and compliance requirements. Selection among these parts is based on the following factors:

Direct Manufacturer Equivalent: BK/MDL-1/10-R is the direct Eaton equivalent designation and maintains identical specifications to the MDL-1/10-R. This part is suitable for direct replacement without any design or application modifications.

Cross-Manufacturer Equivalents: The Littelfuse parts 0313.100HXP, 0313.100MXP, and 0313.100VXP are parametric equivalents manufactured by Littelfuse Inc. These parts satisfy all electrical and mechanical requirements and carry identical CE, CSA, and UL approvals. All parts are RoHS3 compliant and REACH unaffected.

Compliance and Certification: All substitute parts carry CE, CSA, and UL certifications, confirming suitability for regulated applications. RoHS3 compliance is maintained across all alternatives.

Inventory and Availability: Part availability varies: MDL-1/10-R (941 pcs), BK/MDL-1/10-R (1136 pcs), 0313.100HXP (962 pcs), 0313.100MXP (2372 pcs), and 0313.100VXP (776 pcs) are in stock.

Frequently Asked Questions (FAQ)

Q: Can BK/MDL-1/10-R be used as a direct replacement for MDL-1/10-R?

A: Yes. BK/MDL-1/10-R is the direct Eaton equivalent with identical electrical specifications, mechanical dimensions, and certifications. No design changes are required.

Q: Are Littelfuse 0313 series fuses compatible with MDL-1/10-R applications?

A: Yes. The 0313.100HXP, 0313.100MXP, and 0313.100VXP are parametric equivalents with matching current rating (100 mA), voltage rating (250 V AC), response time (Slow Blow), package type (3AB, 3AG), and physical dimensions (0.250" Dia x 1.250" L). All carry identical CE, CSA, and UL approvals.

Q: What are the critical parameters for substitution?

A: Current rating (100 mA), voltage rating (250 V AC), fuse type (Cartridge, Glass), response time (Slow Blow), package designation (3AB, 3AG), physical dimensions (0.250" Dia x 1.250" L), and breaking capacity (35A) must match exactly. All listed substitutes meet these requirements.

Q: Do all substitute parts require the same holder?

A: Yes. All parts use the 3AB and 3AG holder standard with identical 1/4" x 1-1/4" dimensions. No holder modifications are necessary when substituting between listed parts.

Q: Are there differences in DC cold resistance between parts?

A: Yes. The MDL-1/10-R has a DC cold resistance of 15.68 Ohms, while Littelfuse parts (0313.100HXP, 0313.100MXP, 0313.100VXP) have 43 Ohms. This difference does not affect substitution eligibility, as DC cold resistance is not a substitution-limiting parameter for this product category.

Q: Are all parts RoHS compliant?

A: Yes. MDL-1/10-R is RoHS Compliant. BK/MDL-1/10-R and all Littelfuse parts are ROHS3 Compliant. All parts meet RoHS requirements.

Q: What is the operating temperature range?

A: MDL-1/10-R does not specify an operating temperature range. Littelfuse parts (0313.100HXP, 0313.100MXP, 0313.100VXP) operate from -55°C to 125°C. This difference does not affect substitution eligibility.
