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

Part Overview

The BK/MDA-V-2/10-R is a 200 mA, 250 V AC/DC ceramic cartridge fuse manufactured by Eaton - Electronics Division. This fuse is designed for through-hole mounting in 3AB, 3AG form factor applications with slow-blow response characteristics. The part is classified as obsolete, making identification of functionally equivalent substitute components essential for ongoing system maintenance, repair, and new design implementations where legacy specifications must be maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/MDA-V-2/10-R is determined by strict equivalence across the following critical parameters:

Current Rating: 200 mA (exact match required)

Voltage Rating: 250 V AC (exact match required)

Fuse Type: Ceramic cartridge construction (exact match required)

Response Characteristic: Slow Blow (exact match required)

Package / Case: 3AB, 3AG form factor with 1/4" x 1-1/4" axial dimensions (exact match required)

Mounting Configuration: Through-hole technology (exact match required)

The substitute part 0325.200HXP from Littelfuse Inc. meets all critical substitution criteria. Both the main part and substitute maintain identical electrical specifications (200 mA, 250 V AC/DC), ceramic construction, slow-blow response, and 3AB/3AG package designation. Physical dimensions remain within acceptable tolerance ranges for direct mechanical and electrical interchange.

Parameter Comparison

Engineering Selection Recommendations

The 0325.200HXP from Littelfuse Inc. is the direct functional equivalent for the obsolete BK/MDA-V-2/10-R. Selection of this substitute is based on the following engineering factors:

Electrical Equivalence: Both parts maintain identical current (200 mA) and voltage (250 V AC) ratings with matching slow-blow response characteristics, ensuring equivalent circuit protection performance.

Mechanical Compatibility: Package designation (3AB, 3AG) and through-hole mounting configuration are identical. Physical dimensions fall within acceptable tolerance ranges (diameter variance: 0.009", length variance: 0.004"), permitting direct mechanical interchange in existing PCB layouts and fuse holders.

Compliance Status: Both parts are ROHS3 compliant. The substitute part carries CE approval and REACH unaffected status, providing enhanced regulatory documentation for applications requiring formal compliance verification.

Product Availability: The substitute part maintains active production status with confirmed inventory availability (1013 pcs), whereas the main part is obsolete. This availability differential makes the substitute the practical choice for ongoing procurement.

Dimensional Tolerance: Minor dimensional variations between the two parts (0.009" diameter, 0.004" length) remain within standard mechanical tolerances for 3AB/3AG cartridge fuses and do not impact functional performance or mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can the 0325.200HXP directly replace the BK/MDA-V-2/10-R in existing applications?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical current ratings (200 mA), voltage ratings (250 V AC), fuse type (ceramic cartridge), response characteristics (slow blow), and package designation (3AB, 3AG). Physical dimensions are within acceptable tolerance ranges for direct interchange in through-hole fuse holders.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution requires exact equivalence in six parameters: current rating (200 mA), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (slow blow), package/case (3AB, 3AG, 1/4" x 1-1/4"), and mounting type (through hole). Deviation in any of these parameters disqualifies a part as a direct substitute.

Q: Why are the physical dimensions slightly different between the two parts?

A: The BK/MDA-V-2/10-R measures 0.266" diameter x 1.292" length, while the 0325.200HXP measures 0.275" diameter x 1.288" length. These variations (0.009" and 0.004" respectively) fall within standard manufacturing tolerances for 3AB/3AG cartridge fuses and do not affect mechanical fit or electrical performance in standard fuse holders.

Q: What compliance certifications does the substitute part carry?

A: The 0325.200HXP is ROHS3 compliant, CE approved, and REACH unaffected. The original BK/MDA-V-2/10-R is ROHS3 compliant. Both parts carry EAR99 ECCN classification and 8536.10.0040 HTSUS code.

Q: Is the substitute part currently available?

A: Yes. The 0325.200HXP maintains active production status with confirmed inventory of 1013 pieces. The original BK/MDA-V-2/10-R is obsolete, making the substitute the only viable option for new procurement.

Q: Are there any performance differences between the two parts?

A: No performance differences exist in the critical electrical parameters. Both parts deliver identical protection at 200 mA, 250 V AC with slow-blow response. The substitute part provides additional technical documentation including breaking capacity (100A), melting I²t (0.213), DC cold resistance (6.77 Ohms), and operating temperature range (-55°C ~ 125°C).
