TR/MDA-V-15 Ceramic Fuse Equivalent & Substitute Parts

Part Overview

The TR/MDA-V-15 is a 15 A, 250 V AC/DC ceramic cartridge fuse manufactured by Eaton - Electronics Division. This fuse is designed for through-hole mounting applications requiring slow-blow response characteristics in a 3AB, 3AG form factor (1/4" x 1-1/4" axial package).

The TR/MDA-V-15 carries an obsolete product status. Identification of equivalent substitute parts is necessary to ensure continued availability for maintenance, repair, and new design implementations where this fuse specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TR/MDA-V-15 is determined by strict equivalence across the following electrical and mechanical parameters:

Mandatory Equivalence Criteria:

• Current Rating: 15 A
• Voltage Rating (AC): 250 V
• Fuse Type: Cartridge, Ceramic
• Response Time: Slow Blow
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (Axial)
• Breaking Capacity @ Rated Voltage: 750 A
• Physical Dimensions: 0.266" Dia x 1.292" L (6.76mm x 32.82mm)
• Mounting Type: Through Hole

The TR/MDA-V-15-R meets all mandatory equivalence criteria and is classified as a direct substitute. The primary distinction between the main part and its substitute is packaging format (bulk versus tape & reel) and product status (obsolete versus active).

Parameter Comparison

Engineering Selection Recommendations

TR/MDA-V-15-R is the direct substitute for TR/MDA-V-15. Selection of TR/MDA-V-15-R is based on the following engineering factors:

1. Product Status: TR/MDA-V-15-R carries active product status, ensuring continued manufacturer support and availability, whereas TR/MDA-V-15 is obsolete.

2. Electrical Equivalence: Both parts maintain identical current rating (15 A), voltage rating (250 V AC), breaking capacity (750 A), and response time (slow blow) characteristics.

3. Mechanical Compatibility: Both parts share identical package specifications (3AB, 3AG), physical dimensions (0.266" Dia x 1.292" L), and through-hole mounting configuration, ensuring direct board-level compatibility.

4. Regulatory Compliance: TR/MDA-V-15-R includes CE certification in addition to CSA and UL approvals present on the original part. TR/MDA-V-15-R achieves ROHS3 compliance, whereas the original part is RoHS non-compliant.

5. Packaging Consideration: TR/MDA-V-15-R is supplied in tape & reel format, suitable for automated assembly processes. Bulk packaging is available through alternative sourcing if required for manual assembly applications.

Frequently Asked Questions (FAQ)

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

A: Yes. TR/MDA-V-15-R is electrically and mechanically equivalent to TR/MDA-V-15. Both parts maintain identical current rating (15 A), voltage rating (250 V AC), breaking capacity (750 A), response time (slow blow), and physical dimensions (0.266" Dia x 1.292" L). Through-hole mounting configuration is identical, enabling direct board-level substitution without design modification.

Q: What is the primary difference between TR/MDA-V-15 and TR/MDA-V-15-R?

A: The primary differences are product status and packaging format. TR/MDA-V-15 is obsolete and supplied in bulk packaging. TR/MDA-V-15-R is an active product supplied in tape & reel format. Both parts are functionally identical in electrical and mechanical specifications.

Q: Does TR/MDA-V-15-R meet RoHS compliance requirements?

A: Yes. TR/MDA-V-15-R is ROHS3 compliant. The original TR/MDA-V-15 is RoHS non-compliant. If RoHS compliance is a design requirement, TR/MDA-V-15-R is the appropriate selection.

Q: Are there any differences in thermal or electrical performance between these parts?

A: Both parts maintain identical breaking capacity (750 A) and response time (slow blow) characteristics. DC cold resistance values differ slightly (0.00543 Ohms for TR/MDA-V-15 versus 0.00553 Ohms for TR/MDA-V-15-R) and melting I²t values differ (206.2 for TR/MDA-V-15 versus 336.82 for TR/MDA-V-15-R). These variations remain within acceptable tolerance for the 15 A, 250 V AC/DC fuse category and do not affect functional equivalence in circuit protection applications.

Q: Is tape & reel packaging compatible with manual assembly processes?

A: Tape & reel packaging is optimized for automated assembly equipment. For manual assembly applications, bulk packaging may be preferred. Consult with your component supplier regarding packaging format availability for TR/MDA-V-15-R.

Q: What certifications does TR/MDA-V-15-R carry?

A: TR/MDA-V-15-R carries CE, CSA, and UL certifications. The original TR/MDA-V-15 carries CSA and UL certifications. Both parts meet the approval requirements for 15 A, 250 V AC/DC ceramic cartridge fuses in industrial and commercial applications.
