BK/MDA-V-15 Equivalent & Substitute Parts

Part Overview

The BK/MDA-V-15 is a 15 A, 250 V AC/DC ceramic cartridge fuse with 3AB, 3AG package configuration and slow-blow response characteristics. This component is classified as obsolete, necessitating identification of active equivalent alternatives for continued system support and procurement. The part features through-hole mounting with 1/4" x 1-1/4" (Axial) dimensions and is manufactured by Eaton - Electronics Division.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BK/MDA-V-15 is determined by strict equivalence across the following parameters:

• Current Rating: 15 A (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" (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 750 A (exact match required)
• Size / Dimension: 0.266" Dia x 1.292" L (6.76mm x 32.82mm) (exact match required)

All substitute parts listed below meet these criteria and are manufactured by Eaton - Electronics Division within the MDA series. Substitutes differ in packaging configuration and product status (active vs. obsolete).

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (BK/MDA-V-15-R, MDA-V-15-R, and TR/MDA-V-15-R) are functionally equivalent to the obsolete BK/MDA-V-15 across all critical electrical and mechanical parameters. Selection among substitutes is determined by packaging and compliance requirements:

BK/MDA-V-15-R (Bulk Packaging): Active product status with 2050 units in stock. ROHS3 compliant with CE, CSA, and UL certifications. Suitable for applications requiring standard bulk packaging.

MDA-V-15-R (Bulk Packaging): Active product status with 744 units in stock. ROHS3 compliant with CE, CSA, and UL certifications. Functionally identical to BK/MDA-V-15-R with equivalent electrical characteristics.

TR/MDA-V-15-R (Tape & Reel Packaging): Active product status with 989 units in stock. ROHS3 compliant with CE, CSA, and UL certifications. Specified for automated assembly processes requiring tape and reel format.

All substitute parts provide enhanced regulatory compliance (ROHS3, CE certification) compared to the obsolete original part. Selection should be based on procurement packaging requirements and assembly methodology.

Frequently Asked Questions (FAQ)

Q: Can BK/MDA-V-15-R, MDA-V-15-R, and TR/MDA-V-15-R be used interchangeably with BK/MDA-V-15?

A: Yes. All three substitute parts are electrically and mechanically equivalent to BK/MDA-V-15. They share identical current rating (15 A), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (slow blow), package configuration (3AB, 3AG), and physical dimensions (0.266" Dia x 1.292" L). Differences are limited to packaging format and product status.

Q: What is the difference between bulk and tape & reel packaging?

A: Bulk packaging (BK/MDA-V-15-R and MDA-V-15-R) is suitable for manual assembly and standard procurement. Tape & reel packaging (TR/MDA-V-15-R) is formatted for automated pick-and-place assembly equipment. Electrical and mechanical specifications are identical across all packaging formats.

Q: Why is the original BK/MDA-V-15 classified as obsolete?

A: The BK/MDA-V-15 is obsolete and has been superseded by active alternatives. The substitute parts provide equivalent functionality with improved regulatory compliance (ROHS3 compliance and CE certification).

Q: Are there compliance differences between the original and substitute parts?

A: Yes. The original BK/MDA-V-15 is RoHS non-compliant. All substitute parts (BK/MDA-V-15-R, MDA-V-15-R, TR/MDA-V-15-R) are ROHS3 compliant. Additionally, substitute parts carry CE certification in addition to CSA and UL certifications present on the original part.

Q: Which substitute part should be selected for new designs?

A: For new designs, any of the three active substitute parts is acceptable based on assembly methodology. Use BK/MDA-V-15-R or MDA-V-15-R for manual assembly with bulk packaging. Use TR/MDA-V-15-R for automated assembly processes requiring tape and reel format.

Q: Are the electrical characteristics identical across all substitute parts?

A: All substitute parts share identical electrical specifications: 15 A current rating, 250 V AC voltage rating, 750 A breaking capacity, and slow-blow response time. Minor variations in melting I²t (336.82 for all active substitutes vs. 206.2 for the obsolete original) and DC cold resistance (0.00553 Ohms for substitutes vs. 0.00543 Ohms for original) do not affect functional equivalence within the specified electrical parameters.
