Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MDQ-1-6/10 is determined by strict equivalence across the following 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 / 6.35mm x 31.75mm (exact match required)
• Mounting Type: Requires Holder (exact match required)

All identified substitute parts meet these criteria. Substitute parts are grouped into two categories: Eaton - Electronics Division series variants (BK/MDL-1-6/10-R and BK/MDQ-1-6/10) and Littelfuse Inc. series equivalents (031301.6HXP and 031301.6MXP).

Frequently Asked Questions (FAQ)

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

A: Yes. BK/MDL-1-6/10-R meets all parametric requirements for direct substitution: 1.6 A current rating, 250 V AC voltage rating, slow-blow response time, cartridge glass fuse type, and 3AB/3AG package compatibility with identical physical dimensions of 0.250" diameter by 1.250" length.

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

A: Both series are manufactured by Eaton - Electronics Division and meet identical electrical and mechanical specifications for the 1.6 A, 250 V application. The primary difference is RoHS compliance status: BK/MDL-1-6/10-R is RoHS Compliant, while BK/MDQ-1-6/10 is RoHS non-compliant.

Q: Are Littelfuse 031301.6HXP and 031301.6MXP interchangeable with Eaton parts?

A: Yes. Both Littelfuse parts meet all parametric requirements for direct substitution in 3AB and 3AG holder applications. They maintain identical current rating, voltage rating, fuse type, response time, and physical dimensions. Littelfuse parts provide additional operating temperature specification (-55°C to 125°C) and higher approval agency certifications (CE, CSA, PSE, UL).

Q: Which substitute part has the highest inventory availability?

A: 031301.6MXP from Littelfuse Inc. has the highest inventory with 1733 pieces in stock, followed by BK/MDQ-1-6/10 with 1125 pieces and BK/MDL-1-6/10-R with 940 pieces.

Q: Do all substitute parts fit the same 3AB and 3AG holders?

A: Yes. All substitute parts maintain the identical package specification of 3AB, 3AG, 1/4" x 1-1/4" and physical dimensions of 0.250" diameter by 1.250" length (6.35mm x 31.75mm), ensuring mechanical compatibility with existing holder installations.

Q: What approval agencies certify the Littelfuse substitute parts?

A: Littelfuse parts 031301.6HXP and 031301.6MXP carry CE, CSA, PSE, and UL approval agencies. The primary Eaton MDQ-1-6/10 carries CSA and UL approvals.
