• 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

Acceptable Variation Parameters:

• RoHS Status: Compliant or non-compliant variants are listed; selection depends on application requirements
• Manufacturer: Eaton - Electronics Division or Littelfuse Inc.
• Series designation: MDL, MDQ, or 313 series

All substitute parts listed maintain electrical and mechanical compatibility with the original MDL-1-6/10-R specification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute (Same Manufacturer): BK/MDL-1-6/10-R is the direct equivalent from Eaton - Electronics Division with identical electrical and mechanical specifications. Both parts are RoHS Compliant and Active in production status. This substitute is preferred when maintaining single-manufacturer sourcing is required.

Secondary Substitute (Same Manufacturer, Alternative Series): BK/MDQ-1-6/10 is manufactured by Eaton - Electronics Division and maintains all critical electrical and mechanical parameters. This part is RoHS non-compliant; selection requires verification that the application does not mandate RoHS compliance.

Cross-Manufacturer Substitutes (Littelfuse Inc.): 031301.6HXP and 031301.6MXP are manufactured by Littelfuse Inc. and provide full electrical and mechanical compatibility. Both parts are ROHS3 Compliant and Active in production. These substitutes support multi-source procurement strategies and offer higher inventory availability (770 and 1733 pieces respectively). Littelfuse parts include additional technical specifications: Breaking Capacity of 100A, Melting I²t of 49.6, DC Cold Resistance of 0.171 Ohms, and Operating Temperature range of -55°C ~ 125°C. Approval agencies include CE, CSA, PSE, and UL.

Selection Criteria:

• For RoHS-compliant applications: MDL-1-6/10-R, BK/MDL-1-6/10-R, 031301.6HXP, or 031301.6MXP
• For non-RoHS applications: BK/MDQ-1-6/10 is available
• For multi-source qualification: Littelfuse 031301.6HXP or 031301.6MXP
• For highest inventory availability: 031301.6MXP (1733 pieces)

Frequently Asked Questions (FAQ)

Q: Can BK/MDL-1-6/10-R be used as a direct replacement for MDL-1-6/10-R?

A: Yes. BK/MDL-1-6/10-R is a parametric equivalent with identical current rating (1.6 A), 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 parts are RoHS Compliant and Active in production.

Q: What is the difference between the Eaton MDL and MDQ series fuses?

A: Both MDL and MDQ series maintain identical electrical and mechanical specifications for the 1.6 A, 250 V AC rating. The primary difference is RoHS compliance status: MDL-1-6/10-R and BK/MDL-1-6/10-R are RoHS Compliant, while BK/MDQ-1-6/10 is RoHS non-compliant. All three are compatible with 3AB and 3AG holders.

Q: Are Littelfuse 031301.6HXP and 031301.6MXP interchangeable with the Eaton MDL-1-6/10-R?

A: Yes. Both Littelfuse parts are parametric equivalents with matching current rating (1.6 A), 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 ROHS3 Compliant and Active in production. The Littelfuse parts include additional technical data: Breaking Capacity of 100A, Melting I²t of 49.6, and Operating Temperature range of -55°C ~ 125°C.

Q: What holder types are compatible with these fuses?

A: All listed substitute parts require a 3AB or 3AG holder. The physical dimensions (0.250" Dia x 1.250" L or 6.35mm x 31.75mm) are standardized across all substitutes, ensuring mechanical compatibility with existing holder installations.

Q: Which substitute part has the highest inventory availability?

A: 031301.6MXP (Littelfuse Inc.) has the highest inventory with 1733 pieces in stock, followed by BK/MDQ-1-6/10 (Eaton) with 1125 pieces.

Q: Are there RoHS compliance differences between the substitute parts?

A: Yes. MDL-1-6/10-R and BK/MDL-1-6/10-R are RoHS Compliant. BK/MDQ-1-6/10 is RoHS non-compliant. Littelfuse parts 031301.6HXP and 031301.6MXP are ROHS3 Compliant. Selection depends on application RoHS requirements.

Q: What approval agencies certify the Littelfuse substitute parts?

A: Littelfuse parts 031301.6HXP and 031301.6MXP carry certifications from CE, CSA, PSE, and UL.
