5SFP 200 Equivalent & Substitute Parts

Part Overview

The 5SFP 200 is a 200 mA, 250 V AC/DC fast-blow glass cartridge fuse with a 5mm x 20mm axial through-hole package manufactured by Bel Fuse Inc. This component is classified as obsolete, making identification of compatible substitute parts essential for ongoing system maintenance and new design implementations. Equivalent parts must maintain identical electrical ratings and mechanical compatibility to ensure proper circuit protection without modification to existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5SFP 200 is determined by strict equivalence across 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 Type: Through Hole (exact match required)
• Breaking Capacity: 35 A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The 0217.200MXEP manufactured by Littelfuse Inc. meets all critical electrical and mechanical parameters for direct substitution. Minor dimensional variations within the 5mm x 20mm package class and differences in secondary parameters such as melting I²t and DC cold resistance do not preclude functional equivalence in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

The 0217.200MXEP is a direct functional equivalent to the 5SFP 200 across all critical electrical and mechanical parameters. Selection of the 0217.200MXEP offers the additional advantage of active product status and ROHS3 compliance, supporting long-term supply chain continuity and regulatory alignment. The obsolete status of the 5SFP 200 necessitates transition to the 0217.200MXEP for new procurement and system maintenance activities.

Frequently Asked Questions (FAQ)

Q: Can the 0217.200MXEP be used as a direct replacement for the 5SFP 200 without circuit modification?

A: Yes. Both components share identical current ratings (200 mA), voltage ratings (250 V AC), fuse type (cartridge, glass), response time (fast blow), and package dimensions (5mm x 20mm axial). Through-hole mounting compatibility is maintained. No circuit modification is required.

Q: What is the significance of the melting I²t difference between the two parts?

A: The melting I²t values (0.03 for 5SFP 200 and 0.02 for 0217.200MXEP) represent thermal energy thresholds for fuse operation. Both values fall within the acceptable range for 200 mA fast-blow fuses and do not affect substitution compatibility in standard circuit protection applications.

Q: Does the RoHS compliance difference affect substitution?

A: The 0217.200MXEP is ROHS3 compliant while the 5SFP 200 is non-compliant. For applications subject to RoHS regulatory requirements, the 0217.200MXEP provides compliance alignment. For legacy systems without RoHS mandates, both parts remain functionally equivalent.

Q: Are there dimensional differences between the two parts?

A: Minor dimensional variations exist within the 5mm x 20mm package class (5SFP 200: 0.217" Dia x 0.827" L; 0217.200MXEP: 0.236" Dia x 0.886" L). These variations remain within standard axial cartridge fuse tolerances and do not affect through-hole mounting compatibility or circuit board layout.

Q: What is the inventory status for each part?

A: The 5SFP 200 has 1,134 pieces in stock (obsolete status). The 0217.200MXEP has 843 pieces in stock (active status). For new designs and long-term applications, the 0217.200MXEP is the recommended selection due to active product status and ongoing availability.
