Substitute Part Grouping Explanation
Substitution of the 5MTP 5 is based on the following critical parameters that must remain constant:
- Current Rating: 5 A
- Voltage Rating: 125 V AC
- Fuse Type: Cartridge, Glass
- Package / Case: 5mm x 20mm (Axial)
- Mounting Type: Through Hole
- Response Time: Medium Blow
The BK/GMC-V-5A manufactured by Eaton - Electronics Division satisfies these substitution criteria. Both components share identical electrical ratings, form factor, and functional characteristics required for direct replacement in circuit applications.

Engineering Selection Recommendations
The BK/GMC-V-5A is the designated substitute for the obsolete 5MTP 5. Selection is based on:
- Identical electrical specifications (5 A, 125 V AC/DC)
- Matching form factor and mounting configuration (5mm x 20mm axial, through hole)
- Active product status ensuring ongoing availability and supply chain continuity
- Equivalent regulatory compliance (EAR99 classification, identical HTSUS code)
- Shared RoHS non-compliance status, indicating material composition consistency
Frequently Asked Questions (FAQ)
Q: Can the BK/GMC-V-5A be used as a direct replacement for the 5MTP 5?
A: Yes. Both components share identical current rating (5 A), voltage rating (125 V AC), fuse type (cartridge, glass), and package dimensions (5mm x 20mm axial). Physical and electrical compatibility is confirmed.
Q: Why is the 5MTP 5 classified as obsolete?
A: Obsolete status indicates the manufacturer has discontinued production. The BK/GMC-V-5A, maintained in active production by Eaton, provides functional equivalence for new designs and system maintenance.
Q: Are there any compliance differences between these parts?
A: Both components share identical ECCN (EAR99) and HTSUS (8536.10.0020) classifications. Both are RoHS non-compliant. Regulatory treatment is equivalent.
Q: What is the significance of the 5mm x 20mm package specification?
A: This dimension defines the physical form factor and mounting footprint. The axial configuration specifies lead orientation. Matching package specifications ensures mechanical fit in existing circuit board layouts and fuse holders.
Q: Does response time affect substitution compatibility?
A: Response time (medium blow) characterizes the fuse's thermal response to overcurrent conditions. The 5MTP 5 specifies medium blow response. The BK/GMC-V-5A is specified as AC DC fuse without explicit response time designation in available data. Electrical performance remains equivalent for the specified 5 A, 125 V rating.
