5MF 200 Glass Cartridge Fuse Equivalent & Substitute Parts

Part Overview

The Bel Fuse Inc. 5MF 200 is a 200 mA, 250 V AC/DC fast-blow glass cartridge fuse in a 5mm x 20mm package format. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The fuse requires a compatible holder for installation and is designed for circuit protection applications requiring fast response characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5MF 200 is determined by strict alignment with the following electrical and mechanical parameters:

• Current Rating: 200 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Package Dimensions: 5mm x 20mm (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Configuration: Requires Holder (exact match required)

All four substitute parts listed below meet these core substitution criteria. Variations in breaking capacity, melting I²t, DC cold resistance, and approval certifications do not disqualify substitution but may influence selection based on application-specific requirements.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are electrically and mechanically compatible with the 5MF 200 based on matching current rating, voltage rating, package dimensions, fuse type, and response characteristics.

For applications requiring RoHS3 compliance, the 0034.1509 (SCHURTER), 0217.200MXP (Littelfuse), and 0235.200HXP (Littelfuse) are suitable selections. The GDB-200MA (Eaton) RoHS status is not specified in available documentation.

For applications requiring comprehensive international approvals, the 0217.200MXP (Littelfuse) carries the broadest certification portfolio including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. The 0235.200HXP (Littelfuse) provides CE, CSA, KC, and UL certifications. The 0034.1509 (SCHURTER) provides CCC, cURus, and VDE certifications. The GDB-200MA (Eaton) provides VDE and UR certifications.

All substitute parts are currently in active production status, ensuring long-term availability compared to the obsolete 5MF 200.

Frequently Asked Questions (FAQ)

Q: Can the 0217.200MXP substitute for the 5MF 200 in existing designs?

A: Yes. The 0217.200MXP matches all critical electrical and mechanical parameters: 200 mA current rating, 250 V AC voltage rating, 5mm x 20mm package, fast-blow response, and cartridge glass fuse type. Both require a compatible holder for installation.

Q: What is the difference between the substitute parts?

A: All four substitutes meet the core substitution criteria. Differences exist in breaking capacity (5MF 200 has 200A; substitutes have 35A), melting I²t values, DC cold resistance, approval certifications, and RoHS compliance status. These differences do not affect basic substitution compatibility but may influence selection for specific application requirements.

Q: Why does the 5MF 200 have a higher breaking capacity than the substitutes?

A: Breaking capacity is a secondary parameter not required for substitution eligibility. The 5MF 200 specifies 200A breaking capacity while all substitutes specify 35A. This difference does not prevent substitution in applications where the 5MF 200 was originally specified, as the lower breaking capacity of substitutes remains adequate for standard circuit protection applications.

Q: Are all substitutes RoHS compliant?

A: Three of the four substitutes are ROHS3 compliant: 0034.1509 (SCHURTER), 0217.200MXP (Littelfuse), and 0235.200HXP (Littelfuse). The GDB-200MA (Eaton) RoHS status is not specified. The original 5MF 200 is RoHS non-compliant.

Q: Which substitute has the lowest DC cold resistance?

A: The 0217.200MXP (Littelfuse) has the lowest DC cold resistance at 1.7 Ohms. The 5MF 200 has 3.4 Ohms, the 0235.200HXP has 3.15 Ohms, and the GDB-200MA has 6.8 Ohms. The 0034.1509 (SCHURTER) DC cold resistance is not specified.

Q: Can I use these substitutes interchangeably in the same holder?

A: Yes. All substitute parts share the identical 5mm x 20mm package dimensions and cartridge glass fuse type, making them mechanically compatible with any holder designed for the 5MF 200.

Q: Which substitute has the best international certification coverage?

A: The 0217.200MXP (Littelfuse) carries the most comprehensive certification portfolio: CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. This makes it suitable for applications requiring multi-regional compliance.
