Equivalent & Substitute Parts for BK/MDA-2/10-R

Part Overview

The Eaton BK/MDA-2/10-R is a 200 mA, 250 V AC/DC ceramic cartridge fuse with slow-blow response characteristics, designed for 3AB and 3AG holder compatibility. This fuse operates in the 1/4" x 1-1/4" form factor and is classified as obsolete. Due to its obsolete product status, equivalent substitute parts from active manufacturers are necessary to maintain circuit protection functionality in applications requiring this electrical specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/MDA-2/10-R is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Current Rating: 200 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Physical Dimensions: 0.250" Dia x 1.250" L (exact match required)

All three substitute parts from Littelfuse Inc. (0326.200HXP, 0326.200MXP, 0326.200VXP) meet these critical parameters and are therefore direct functional equivalents. These parts are classified as active products, ensuring ongoing availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The three Littelfuse 326 series fuses (0326.200HXP, 0326.200MXP, 0326.200VXP) are direct functional equivalents to the obsolete Eaton BK/MDA-2/10-R. Selection among these three substitute parts is based on availability and packaging requirements:

0326.200MXP is the recommended primary substitute, with 1377 pieces in current inventory, providing the highest stock availability for immediate procurement.

0326.200VXP serves as a secondary option with 847 pieces available.

0326.200HXP is available with 685 pieces in stock.

All three substitute parts carry CE approval certification and ROHS3 compliance, meeting regulatory requirements equivalent to or exceeding the original part specification. The active product status of all three Littelfuse alternatives ensures long-term supply chain reliability and technical support continuity.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0326.200MXP, 0326.200VXP, or 0326.200HXP be used as direct replacements for the Eaton BK/MDA-2/10-R?

A: Yes. All three Littelfuse parts are direct functional equivalents. They match the critical electrical parameters (200 mA, 250 V AC, slow-blow ceramic cartridge) and mechanical specifications (3AB/3AG holder compatibility, 1/4" x 1-1/4" form factor) required for the BK/MDA-2/10-R application.

Q: What is the difference between the three Littelfuse substitute parts?

A: The 0326.200HXP, 0326.200MXP, and 0326.200VXP are electrically and mechanically identical. They differ only in packaging designation and current inventory levels. Selection should be based on procurement availability and internal part numbering systems.

Q: Are the substitute parts compatible with existing 3AB and 3AG fuse holders?

A: Yes. All substitute parts are designed for 3AB and 3AG holder compatibility with identical 1/4" x 1-1/4" dimensions, ensuring direct mechanical fit in existing circuit protection installations.

Q: What certifications do the substitute parts carry?

A: The Littelfuse substitute parts carry CE approval and are ROHS3 compliant, meeting regulatory standards for electronic component use in industrial and commercial applications.

Q: Why is the original Eaton BK/MDA-2/10-R classified as obsolete?

A: The BK/MDA-2/10-R has been discontinued by Eaton. The Littelfuse 326 series alternatives provide equivalent functionality with active product status, ensuring ongoing availability and manufacturer support.
