Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5MFP 200 is based on strict equivalence of electrical and mechanical parameters. The primary substitute, 0217.200MXEP from Littelfuse Inc., maintains identical current rating (200 mA), voltage rating (250 V AC), fuse type (cartridge glass), response characteristic (fast blow), and operating temperature range (-55°C ~ 125°C). Both components are through-hole mounted devices with compatible 5mm x 20mm package dimensions.

The substitution logic is determined by the following critical parameters:

• Current Rating: 200 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Configuration: Through Hole (exact match required)
• Temperature Operating Range: -55°C ~ 125°C (exact match required)

Parameter Comparison

Engineering Selection Recommendations

The 0217.200MXEP from Littelfuse Inc. is the direct functional equivalent for the obsolete 5MFP 200. Both components share identical electrical ratings and mechanical form factors, ensuring pin-compatible replacement in through-hole applications.

The 0217.200MXEP offers additional advantages in terms of product lifecycle status and regulatory compliance. As an active product, it provides assured long-term availability and supply chain continuity. The component carries ROHS3 compliance, whereas the 5MFP 200 is non-compliant, making the substitute preferable for applications subject to RoHS regulations. The 0217.200MXEP also carries expanded approval certifications (CCC, K-MARK, SEMKO, VDE) beyond the original part's CE, CSA, and UL approvals, providing broader regulatory acceptance across international markets.

Frequently Asked Questions (FAQ)

Q: Can the 0217.200MXEP be used as a direct replacement for the 5MFP 200?

A: Yes. Both components are electrically and mechanically equivalent with identical current ratings (200 mA), voltage ratings (250 V AC), fuse types (cartridge glass), response characteristics (fast blow), and package dimensions (5mm x 20mm axial). Through-hole mounting compatibility is maintained.

Q: What are the physical dimension differences between these parts?

A: The 5MFP 200 has a diameter of 0.217" (5.50mm) and length of 0.827" (21.00mm). The 0217.200MXEP has a diameter of 0.236" (6.00mm) and length of 0.886" (22.50mm). These minor dimensional variations remain within typical through-hole fuse socket tolerances and do not affect functional compatibility.

Q: Are there compliance differences between the two parts?

A: The 5MFP 200 is RoHS non-compliant, while the 0217.200MXEP is ROHS3 compliant. For applications requiring RoHS compliance, the 0217.200MXEP is the appropriate selection. Both components are REACH unaffected.

Q: What is the difference in breaking capacity between these fuses?

A: The 5MFP 200 has a breaking capacity of 200A at rated voltage, while the 0217.200MXEP has a breaking capacity of 35A at rated voltage. Both values are within acceptable ranges for their respective product lines and do not affect substitution eligibility for standard overcurrent protection applications.

Q: How do the DC cold resistance values compare?

A: The 5MFP 200 has a DC cold resistance of 3.4 Ohms, while the 0217.200MXEP has a DC cold resistance of 1.7 Ohms. The lower resistance of the substitute may result in marginally reduced voltage drop across the fuse element in DC applications, but both values are acceptable for standard circuit protection use.
