Substitute Part Grouping Explanation

Substitution eligibility for the 5HFP 100 is determined by strict alignment with the following electrical and mechanical parameters:

• Current Rating: 100 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Mounting Type: Through Hole (exact match required)

The substitute part 0216.100MXEP (Littelfuse Inc., Series 216) meets all mandatory electrical and mechanical criteria for direct substitution.

Parameter Comparison

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are 100 mA, 250 V AC/DC ceramic cartridge fuses with fast-blow response in a 5mm x 20mm axial package. Electrical and mechanical parameters are equivalent, enabling direct substitution in through-hole applications.

Q: Are there physical dimension differences between these parts?

A: The 5HFP 100 has a nominal dimension of 0.217" Dia x 0.827" L (5.50mm x 21.00mm), while the 0216.100MXEP measures 0.236" Dia x 0.886" L (6.00mm x 22.50mm). These minor variations remain within the 5mm x 20mm package classification and do not affect functional compatibility in standard through-hole mounting applications.

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

A: The 5HFP 100 has a DC cold resistance of 3.85 Ohms, while the 0216.100MXEP measures 5.7925 Ohms. This difference does not affect fuse operation at rated current and voltage conditions.

Q: Does the 0216.100MXEP meet RoHS requirements?

A: Yes. The 0216.100MXEP is ROHS3 compliant. The original 5HFP 100 is RoHS non-compliant. For applications requiring RoHS compliance, the substitute part satisfies this requirement.

Q: Are both parts suitable for the same temperature operating range?

A: Yes. Both the 5HFP 100 and 0216.100MXEP operate across the same temperature range of -55°C to 125°C.
