Eaton BK/MDL-1-6/10 Glass Cartridge Fuse 1.6A 250VAC Equivalent & Substitute Parts

Part Overview

The Eaton BK/MDL-1-6/10 is a 1.6 ampere, 250 volt AC/DC glass cartridge fuse with slow blow response characteristics. This component is classified as obsolete product status. The fuse requires a 3AB or 3AG holder and features a 1/4" x 1-1/4" form factor (6.35mm x 31.75mm). Due to its obsolete classification, equivalent and substitute parts from active product lines are necessary for ongoing system maintenance and new design implementations. Substitute components must maintain identical electrical ratings and mechanical compatibility with existing holder infrastructure.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Current Rating: 1.6 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Slow Blow (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)

All substitute parts listed below meet these critical parameters and are therefore mechanically and electrically interchangeable with the main part BK/MDL-1-6/10 within systems designed for this specification.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Line Replacement:

The Eaton BK/MDL-1-6/10-R and MDL-1-6/10-R are direct Eaton replacements with active product status. Both parts maintain identical electrical and mechanical specifications to the obsolete BK/MDL-1-6/10. The BK/MDL-1-6/10-R carries RoHS Compliant certification, making it suitable for applications with environmental compliance requirements. The MDL-1-6/10-R also carries RoHS Compliant status. Both are available in bulk packaging.

For Cross-Manufacturer Substitution:

The Littelfuse 313 series parts (031301.6HXP, 031301.6MXP, 031301.6VXP) provide parametric equivalence with active product status and ROHS3 Compliant certification. These components carry broader approval agency certifications including CE, CSA, PSE, and UL. Operating temperature range is specified as -55°C to 125°C. Breaking capacity at rated voltage is 100A. These parts are suitable for applications requiring enhanced regulatory compliance documentation.

For Eaton MDQ Series:

The BK/MDQ-1-6/10 and MDQ-1-6/10 represent alternative Eaton series options with active product status. The MDQ-1-6/10 carries CSA and UL approval agency certifications with 200A breaking capacity at rated voltage, providing enhanced performance specifications. Both maintain identical electrical and mechanical compatibility.

Selection Priority:

1. Active product status is preferred over obsolete classification for new designs and long-term availability assurance.
2. RoHS compliance status should align with end-application regulatory requirements.
3. Approval agency certifications should match system qualification documentation.

Frequently Asked Questions (FAQ)

Q: Can BK/MDL-1-6/10 be directly replaced with BK/MDL-1-6/10-R?

A: Yes. Both parts share identical electrical ratings (1.6A, 250V AC), fuse type (Cartridge, Glass), response time (Slow Blow), and mechanical dimensions (0.250" Dia x 1.250" L). Both require 3AB or 3AG holders. The primary difference is product status (obsolete vs. active) and RoHS compliance. Direct mechanical and electrical substitution is valid.

Q: Are Littelfuse 313 series fuses compatible with Eaton MDL series holders?

A: Yes. The Littelfuse 031301.6HXP, 031301.6MXP, and 031301.6VXP all share identical package specifications (3AB, 3AG, 1/4" x 1-1/4") and mechanical dimensions (0.250" Dia x 1.250" L). These parts are mechanically interchangeable with Eaton MDL and MDQ series holders. Electrical ratings are identical: 1.6A, 250V AC, Slow Blow response.

Q: What is the difference between 031301.6HXP, 031301.6MXP, and 031301.6VXP?

A: All three Littelfuse parts share identical electrical ratings, mechanical dimensions, and response characteristics. The designations (HXP, MXP, VXP) represent different product variants within the 313 series. All three carry identical approval agencies (CE, CSA, PSE, UL), operating temperature range (-55°C to 125°C), breaking capacity (100A), and melting I²t (49.6). Selection between these variants should be based on specific application requirements or existing inventory management protocols.

Q: Is the MDQ-1-6/10 superior to MDL-1-6/10-R?

A: The MDQ-1-6/10 carries CSA and UL approval certifications and specifies 200A breaking capacity at rated voltage, compared to unspecified breaking capacity for MDL-1-6/10-R. Both maintain identical electrical ratings and mechanical compatibility. Selection should be based on application breaking capacity requirements and required approval agency certifications.

Q: Can I use these fuses in applications requiring RoHS compliance?

A: Yes, for RoHS-compliant applications, select from: BK/MDL-1-6/10-R, MDL-1-6/10-R, MDQ-1-6/10, 031301.6HXP, 031301.6MXP, or 031301.6VXP. The original BK/MDL-1-6/10 and BK/MDQ-1-6/10 are RoHS non-compliant and should not be used in applications with RoHS requirements.

Q: What holder types are required for these fuses?

A: All listed parts require 3AB or 3AG holder types. The 1/4" x 1-1/4" (6.35mm x 31.75mm) form factor is standardized across all substitute parts. Verify existing holder compatibility before component selection.
