5MTP 7-R Equivalent & Substitute Parts

Part Overview

The 5MTP 7-R is a glass cartridge fuse manufactured by Bel Fuse Inc., rated for 7A at 125VAC with a 5mm x 20mm axial form factor. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and repair applications. The medium-blow response characteristic and 300A breaking capacity at rated voltage define its operational profile in circuit protection applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5MTP 7-R is determined by strict equivalence across the following parameters:

• Current Rating: 7 A (exact match required)
• Voltage Rating: 125 V AC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 5mm x 20mm Axial (exact match required)
• Response Time: Medium Blow (exact match required)

The BK/GMC-V-7A manufactured by Eaton - Electronics Division meets all these criteria and is classified as an active product, providing continuity for applications requiring the 5MTP 7-R specification.

Parameter Comparison

Engineering Selection Recommendations

The BK/GMC-V-7A is the designated substitute for the obsolete 5MTP 7-R based on matching electrical and mechanical specifications. The Eaton component maintains active product status, ensuring availability for procurement and supply chain continuity. Both parts share identical HTSUS classification (8536.10.0020) and ECCN designation (EAR99).

Compliance considerations differ between the two parts: the 5MTP 7-R carries RoHS3 compliance and REACH Unaffected status, while the BK/GMC-V-7A is RoHS non-compliant. System designers must evaluate regulatory requirements for their specific application before final component selection.

Frequently Asked Questions (FAQ)

Q: Can the BK/GMC-V-7A directly replace the 5MTP 7-R in existing circuits?

A: Yes, the BK/GMC-V-7A meets all specified electrical and mechanical parameters: 7A current rating, 125V AC voltage rating, medium-blow response characteristic, and 5mm x 20mm axial package form factor. Physical and electrical compatibility is established.

Q: What is the significance of the obsolete status of the 5MTP 7-R?

A: Obsolete status indicates the part is no longer manufactured by Bel Fuse Inc. The BK/GMC-V-7A, classified as active, provides a current-production alternative with equivalent specifications.

Q: Are there compliance differences between these two fuses?

A: Yes. The 5MTP 7-R is RoHS3 compliant and REACH unaffected. The BK/GMC-V-7A is RoHS non-compliant. Applications subject to RoHS or REACH regulations must account for this distinction in component selection.

Q: What parameters must match exactly for substitution?

A: Current rating (7A), voltage rating (125V AC), fuse type (cartridge glass), package dimensions (5mm x 20mm axial), and response time (medium blow) must all match exactly. Deviation in any parameter disqualifies substitution.

Q: Are both parts suitable for the -55°C to 125°C operating temperature range?

A: The 5MTP 7-R is specified for -55°C to 125°C operation. Operating temperature specifications for the BK/GMC-V-7A are not provided in the available data.
