Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5MFP 700 is determined by strict equivalence across the following critical parameters:

• Current Rating: 700 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 200 A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The 5MFP 700-R variant meets all substitution criteria and is classified as an active product, making it the direct equivalent for applications currently using the obsolete 5MFP 700.

Parameter Comparison

Engineering Selection Recommendations

The 5MFP 700-R is the direct substitute for the obsolete 5MFP 700. Both parts share identical electrical and mechanical specifications, including current rating, voltage rating, fuse type, response time, package dimensions, and operating temperature range. The 5MFP 700-R carries active product status, ensuring ongoing availability and supply chain continuity.

The 5MFP 700-R provides enhanced compliance posture with ROHS3 certification compared to the non-compliant status of the original 5MFP 700. Approval certifications for the substitute include CE, CSA, and cULus, providing comprehensive regulatory coverage for global applications.

For new designs or component replenishment, the 5MFP 700-R is the appropriate selection. Existing designs using the 5MFP 700 may transition to the 5MFP 700-R without circuit modification, as all functional and mechanical parameters remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can the 5MFP 700-R be used as a direct replacement for the 5MFP 700?

A: Yes. The 5MFP 700-R meets all electrical and mechanical specifications of the 5MFP 700, including current rating (700 mA), voltage rating (250 V AC), fuse type (cartridge, glass), response time (fast blow), package dimensions (5mm x 20mm axial), and operating temperature range (-55°C ~ 125°C). No circuit modifications are required.

Q: What is the primary reason to transition from 5MFP 700 to 5MFP 700-R?

A: The 5MFP 700 is classified as obsolete product status. The 5MFP 700-R is an active product with guaranteed supply availability. Additionally, the 5MFP 700-R provides ROHS3 compliance, whereas the original part is non-compliant.

Q: Are there any differences in physical dimensions between these parts?

A: No. Both the 5MFP 700 and 5MFP 700-R share identical package dimensions of 5mm x 20mm (axial) with a through-hole mounting type. They are mechanically interchangeable.

Q: What certifications does the 5MFP 700-R carry?

A: The 5MFP 700-R holds CE, CSA, and cULus approvals. The original 5MFP 700 carries CE, CSA, and UL certifications. Both meet the approval requirements for industrial and consumer applications.

Q: Is the 5MFP 700-R available in different packaging options?

A: The 5MFP 700-R is supplied in bulk packaging. Packaging specifications should be confirmed with the supplier for specific order requirements.
