Equivalent & Substitute Parts: TR/MDA-V-15-R

Part Overview

The TR/MDA-V-15-R is a 15 A, 250 V AC/DC ceramic cartridge fuse manufactured by Eaton - Electronics Division. This slow-blow fuse is designed for through-hole mounting in 3AB and 3AG package configurations with axial lead geometry (1/4" x 1-1/4"). The part is currently active in production and maintains full compliance with CE, CSA, and UL approval standards. Identifying equivalent substitute parts is necessary when the tape and reel packaging format is unavailable or when bulk packaging is preferred for inventory management and cost optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TR/MDA-V-15-R is limited to parts that maintain identical electrical and mechanical specifications. The critical parameters that determine substitutability are:

• Current Rating: 15 A (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Ceramic Cartridge (exact match required)
• Response Time: Slow Blow (exact match required)
• Package Configuration: 3AB, 3AG, 1/4" x 1-1/4" Axial (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity: 750 A @ Rated Voltage (exact match required)

The only allowable variation is packaging format (tape and reel versus bulk), which does not affect electrical performance or mechanical compatibility. All substitute parts must maintain identical series designation (MDA), approval certifications (CE, CSA, UL), and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

The BK/MDA-V-15-R is a direct electrical and mechanical equivalent to the TR/MDA-V-15-R. Both parts are manufactured by Eaton - Electronics Division, carry identical electrical ratings, and maintain full compliance with CE, CSA, and UL approval standards. Both parts are ROHS3 compliant and currently active in production.

The distinction between these parts is packaging format only. The TR designation indicates tape and reel packaging, while the BK designation indicates bulk packaging. This difference affects inventory handling and component placement automation compatibility but does not alter electrical performance, thermal characteristics, or mechanical fit within the circuit.

Selection between these parts should be based on:

• Availability of required packaging format for your assembly process
• Inventory management requirements
• Current stock levels and lead times
• Compatibility with component placement equipment

Both parts are suitable for direct substitution in applications requiring a 15 A, 250 V AC/DC ceramic cartridge fuse with slow-blow response characteristics.

Frequently Asked Questions (FAQ)

Q: Can BK/MDA-V-15-R be used as a direct replacement for TR/MDA-V-15-R in circuit applications?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (bulk versus tape and reel). Circuit performance, protection characteristics, and thermal behavior are identical.

Q: What does the TR and BK prefix indicate?

A: TR indicates tape and reel packaging format, suitable for automated component placement equipment. BK indicates bulk packaging format, typically used for manual assembly or alternative handling methods. The electrical specifications remain unchanged.

Q: Are there any compatibility issues when switching between these two part numbers?

A: No compatibility issues exist for circuit-level applications. Both parts use identical 3AB, 3AG package configurations with 1/4" x 1-1/4" axial geometry. Compatibility considerations apply only to assembly process equipment and inventory management systems.

Q: Do both parts maintain the same approval certifications?

A: Yes. Both TR/MDA-V-15-R and BK/MDA-V-15-R carry identical CE, CSA, and UL approvals. RoHS3 compliance status is identical for both parts.

Q: What is the melting I²t value, and is it identical between these parts?

A: The melting I²t value is 336.82 for both parts. This parameter defines the thermal energy required to melt the fuse element and is identical across both packaging formats.

Q: Can these fuses be used in AC and DC applications?

A: Yes. Both parts are rated for 250 V AC/DC operation. The 15 A current rating applies to both AC and DC circuits.

Q: What is the breaking capacity, and why is it important?

A: The breaking capacity is 750 A at rated voltage. This specification defines the maximum fault current the fuse can safely interrupt without rupturing the fuse body or creating a hazardous condition.
