Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5HFP 100-R is determined by strict equivalence across the following critical parameters:

• Current Rating: 100 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
• Mounting Type: Through Hole (exact match required)

The substitute part 0216.100MXEP (Littelfuse Inc., Series 216) meets all critical electrical and mechanical parameters. This part is currently active in production, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The 0216.100MXEP is a direct functional equivalent to the 5HFP 100-R. Both components share identical electrical ratings, response characteristics, and mechanical form factors. The substitute part carries active product status with expanded regulatory approvals (SEMKO, UR, VDE in addition to the original certifications), ensuring compliance across broader geographic and application requirements. Both parts maintain ROHS3 compliance and identical operating temperature specifications. Selection of the 0216.100MXEP eliminates obsolescence risk while maintaining full electrical and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 0216.100MXEP be used as a direct replacement for the 5HFP 100-R?

A: Yes. Both components are 100 mA, 250 V AC/DC ceramic cartridge fuses with identical fast-blow response, 1.5 kA breaking capacity, and 5mm x 20mm axial package dimensions. Electrical performance and circuit protection characteristics are equivalent.

Q: Are there physical installation differences between these parts?

A: Physical dimensions differ slightly. The 5HFP 100-R measures 0.217" diameter x 0.827" length (5.50mm x 21.00mm), while the 0216.100MXEP measures 0.236" diameter x 0.886" length (6.00mm x 22.50mm). Both fit standard 5mm x 20mm fuse holders, though the substitute part has marginally larger dimensions. Verify mechanical clearance in confined mounting spaces.

Q: What is the difference in DC cold resistance between these parts?

A: The 5HFP 100-R has 3.85 Ohms DC cold resistance, while the 0216.100MXEP has 5.7925 Ohms. This difference does not affect circuit protection function but may introduce minimal voltage drop variations in high-current applications. Verify acceptability in your specific circuit design.

Q: Are regulatory certifications equivalent?

A: Both parts hold CCC, CE, CSA, and cULus/UR certifications. The 0216.100MXEP includes additional SEMKO and VDE approvals, providing broader geographic compliance. Both are ROHS3 compliant and REACH unaffected.

Q: Why is the 5HFP 100-R obsolete?

A: Bel Fuse Inc. has discontinued this product line. The 0216.100MXEP from Littelfuse Inc. remains in active production with equivalent specifications, ensuring continued availability for replacement and new designs.
