5MF 200-R Equivalent & Substitute Parts

Part Overview

The 5MF 200-R is a 200 mA, 250 V AC/DC fast-blow glass cartridge fuse in 5mm x 20mm package format manufactured by Bel Fuse Inc. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. Substitute parts must maintain identical electrical ratings and mechanical compatibility with the original holder requirements.

Key Parameters

Parameter	Value
Current Rating	200 mA
Voltage Rating (AC)	250 V
Fuse Type	Cartridge, Glass
Response Time	Fast Blow
Package / Case	5mm x 20mm
Mounting Type	Requires Holder
Operating Temperature Range	-55°C ~ 125°C
RoHS Status	ROHS3 Compliant

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (200 mA), voltage rating (250 V AC), fuse type (cartridge glass), response time (fast blow), and physical package dimensions (5mm x 20mm). All identified substitute parts meet these core requirements and are compatible with standard 5x20mm fuse holders.

The substitute parts are grouped into two categories based on product status: Direct Substitutes (active status, identical specifications) and Similar Substitutes (active status, minor variations in secondary parameters such as breaking capacity or melting I²t).

Engineering Selection Recommendations

All substitute parts listed maintain the core electrical and mechanical specifications required for direct replacement in 5x20mm fuse holder applications. Selection among active alternatives should be based on availability, compliance certifications required for the target application, and secondary parameter alignment with system design specifications.

The Littelfuse 0235.200HXP and 0235.200MXP offer the closest electrical alignment with the original 5MF 200-R, with active product status and comprehensive certification coverage (CE, CSA, KC, UL). The Littelfuse 0217.200MXP provides the broadest certification scope (CCC, CE, CSA, K-MARK, SEMKO, UL, VDE) for applications requiring multi-regional compliance. The SCHURTER 0034.1509 and Eaton GDB-200MA are suitable alternatives where specific manufacturer certifications are required.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts be used interchangeably with the 5MF 200-R?

A: All listed substitute parts share identical current rating (200 mA), voltage rating (250 V AC), fuse type (cartridge glass), response time (fast blow), and physical dimensions (5mm x 20mm). They are mechanically and electrically compatible with standard 5x20mm fuse holders. Secondary parameters such as breaking capacity and melting I²t vary; system design specifications should be consulted to confirm suitability.

Q: What is the significance of the breaking capacity difference between the original part and substitutes?

A: The 5MF 200-R specifies 200A breaking capacity, while most substitutes specify 35A. Breaking capacity defines the maximum fault current the fuse can safely interrupt. Applications requiring the higher 200A rating should confirm substitute part specifications against system fault current calculations.

Q: Are all substitute parts RoHS3 compliant?

A: The Littelfuse 0235.200HXP, 0235.200MXP, 0217.200MXP, and SCHURTER 0034.1509 are confirmed ROHS3 compliant. The Eaton GDB-200MA RoHS status is not specified in available data.

Q: Which substitute offers the best certification coverage?

A: The Littelfuse 0217.200MXP provides the most comprehensive certification scope, including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE approvals, suitable for applications requiring multi-regional compliance.

Q: Are there packaging considerations when selecting a substitute?

A: All substitute parts are available in bulk packaging and are compatible with standard 5x20mm fuse holder assemblies. No special packaging or mounting modifications are required for direct replacement.
