Equivalent & Substitute Parts for 5MFP 200-R

Part Overview

The 5MFP 200-R is a 200 mA, 250 V AC/DC fast-blow glass cartridge fuse in a 5mm x 20mm axial package manufactured by Bel Fuse Inc. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations. Substitute parts must maintain identical electrical ratings and mechanical compatibility to ensure proper circuit protection without modification to existing installations.

Key Parameters

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), package dimensions (5mm x 20mm axial), and mounting configuration (through hole). All identified substitutes meet these core electrical and mechanical requirements.

The substitute parts are categorized as follows:

Direct Substitutes (0235.200HXEP, 0235.200MXEP): These Littelfuse 235 series components provide complete functional equivalence with identical electrical ratings, response characteristics, and package specifications. Both parts are active products with current manufacturing status.

Similar Substitute (0217.200MXEP): This Littelfuse 217 series component matches all primary electrical and mechanical parameters. While classified as a similar rather than direct substitute, it maintains full compatibility with the 5MFP 200-R specification envelope.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing availability, addressing the obsolescence status of the 5MFP 200-R. Selection between direct and similar substitutes should be based on supply chain requirements and regional compliance certifications.

The 0235.200HXEP and 0235.200MXEP (Littelfuse 235 series) are classified as direct substitutes and represent the primary replacement options. Both maintain identical electrical specifications and mechanical form factors. The 0235.200HXEP carries certifications for CE, CSA, KC, and UL; the 0235.200MXEP carries the same certification set.

The 0217.200MXEP (Littelfuse 217 series) is classified as a similar substitute and provides an alternative with expanded regional certifications including CCC, SEMKO, and VDE in addition to CE, CSA, and UL. This part is suitable for applications requiring broader international compliance coverage.

All substitute parts maintain ROHS3 compliance and operate across the identical temperature range (-55°C ~ 125°C), ensuring compatibility with existing thermal design parameters.

Frequently Asked Questions (FAQ)

Q: Can the 0235.200HXEP or 0235.200MXEP be used as direct replacements for the 5MFP 200-R?

A: Yes. Both Littelfuse 235 series parts are classified as direct substitutes. They match the 5MFP 200-R across all critical electrical parameters (200 mA current rating, 250 V AC voltage rating), response time (fast blow), and mechanical package (5mm x 20mm axial through-hole). No circuit modifications are required.

Q: What is the difference between the direct substitutes (0235.200HXEP, 0235.200MXEP) and the similar substitute (0217.200MXEP)?

A: All three parts meet the core electrical and mechanical requirements. The 235 series parts are designated as direct substitutes due to identical series classification within Littelfuse's product line. The 217 series part is designated as similar because it belongs to a different series within the same manufacturer, though it maintains full electrical and mechanical compatibility. The 0217.200MXEP offers expanded regional certifications (CCC, SEMKO, VDE) compared to the 235 series.

Q: Are there any dimensional differences between the 5MFP 200-R and the substitute parts?

A: The 5MFP 200-R has a specified dimension of 0.217" Dia x 0.827" L (5.50mm x 21.00mm). The substitute parts are specified as 0.236" Dia x 0.886" L (6.00mm x 22.50mm). These minor dimensional variations remain within the functional tolerance of standard 5mm x 20mm axial cartridge fuse mounting configurations and do not affect mechanical compatibility in through-hole applications.

Q: Which certifications should I prioritize when selecting a substitute?

A: Selection should be based on the regulatory requirements of your target market. The 0235.200HXEP and 0235.200MXEP carry CE, CSA, KC, and UL certifications. The 0217.200MXEP carries an expanded set including CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. Choose based on your specific regional compliance obligations.

Q: Are all substitute parts currently in stock?

A: Yes. The 0235.200HXEP has 758 units in stock, the 0235.200MXEP has 658 units in stock, and the 0217.200MXEP has 843 units in stock. All parts are classified as new original inventory.
