5SFP 200-R Equivalent & Substitute Parts

Part Overview

The 5SFP 200-R is a 200 mA, 250 V AC/DC fast-blow glass cartridge fuse with a 5mm x 20mm axial package manufactured by Bel Fuse Inc. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The fuse is designed for through-hole mounting applications requiring fast response protection in circuits rated up to 250 V AC.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5SFP 200-R are qualified based on 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)
• Package / Case: 5mm x 20mm axial configuration (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity: 35 A @ rated voltage (exact match required)

Two active substitute parts meet these criteria: BK/S500-V-200-R (Eaton - Electronics Division) and 0217.200MXEP (Littelfuse Inc.). Both maintain electrical and mechanical compatibility with the original 5SFP 200-R specification.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with current manufacturing status, addressing the obsolescence of the original 5SFP 200-R.

BK/S500-V-200-R (Eaton - Electronics Division) is approved by BSI, CCC, CSA, cULus, IMQ, SEMKO, and VDE. This part carries a lower melting I²t value (0.016) and higher DC cold resistance (6.8 Ohms) compared to the original specification. Physical dimensions are nearly identical to the 5SFP 200-R (0.218" Dia x 0.831" L versus 0.217" Dia x 0.827" L), ensuring mechanical compatibility in standard fuse holders.

0217.200MXEP (Littelfuse Inc.) is approved by CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE. This part maintains the original operating temperature range (-55°C ~ 125°C) and carries a melting I²t value (0.02) closer to the original specification. Physical dimensions are slightly larger (0.236" Dia x 0.886" L), which may require verification for fit in space-constrained applications.

Both parts are RoHS compliant and carry identical electrical ratings (200 mA, 250 V AC, 35 A breaking capacity, fast-blow response). Selection between these substitutes depends on specific application requirements regarding thermal characteristics, resistance profile, and physical space constraints.

Frequently Asked Questions (FAQ)

Q: Can BK/S500-V-200-R and 0217.200MXEP be used interchangeably with the 5SFP 200-R?

A: Both parts meet the core electrical specifications (200 mA, 250 V AC, fast-blow, 35 A breaking capacity) and package type (5mm x 20mm axial cartridge). However, dimensional variations exist. The Eaton part (BK/S500-V-200-R) has dimensions nearly identical to the original. The Littelfuse part (0217.200MXEP) is slightly larger and should be verified for fit in existing fuse holders before deployment.

Q: What are the differences in melting I²t values between these parts?

A: The 5SFP 200-R has a melting I²t of 0.03, the BK/S500-V-200-R has 0.016, and the 0217.200MXEP has 0.02. These values indicate the thermal energy required to melt the fuse element. Lower I²t values result in faster response to overcurrent conditions. The Littelfuse part (0217.200MXEP) provides a closer thermal characteristic match to the original specification.

Q: Are there compliance or certification differences between the substitute parts?

A: Both substitutes carry multiple international certifications. The Eaton part includes BSI approval in addition to CCC, CSA, cULus, IMQ, SEMKO, and VDE. The Littelfuse part includes K-MARK and UL approvals in addition to CCC, CE, CSA, SEMKO, and VDE. Both are RoHS compliant. Verify that the required certifications for your application are present on the selected substitute.

Q: How do DC cold resistance values affect part selection?

A: The 5SFP 200-R has a DC cold resistance of 1.1 Ohms, the BK/S500-V-200-R has 6.8 Ohms, and the 0217.200MXEP has 1.7 Ohms. Higher resistance increases voltage drop across the fuse during normal operation. For applications sensitive to voltage drop or power dissipation, the Littelfuse part (0217.200MXEP) with 1.7 Ohms provides closer performance to the original 1.1 Ohms specification.

Q: What is the inventory status of these substitute parts?

A: The 5SFP 200-R (obsolete) has 1068 pieces in stock. BK/S500-V-200-R has 1000 pieces available. 0217.200MXEP has 843 pieces available. Both active substitutes are currently in stock.
