Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5HFP 2-R are qualified based on the following criteria:

Electrical Parameters (Critical):

• Current Rating: 2 A
• Voltage Rating (AC): 250 V
• Breaking Capacity: 1.5 kA
• Response Time: Fast Blow

Mechanical Parameters (Critical):

• Package / Case: 5mm x 20mm (Axial)
• Mounting Type: Through Hole

Environmental Parameters:

• Operating Temperature Range: -55°C ~ 125°C

All identified substitute parts match these core parameters, ensuring functional equivalence and direct replacement capability in the 5HFP 2-R application circuit.

Parameter Comparison

Engineering Selection Recommendations

All four parts maintain active product status and are RoHS compliant, meeting current environmental and regulatory requirements. Selection among these substitutes should be based on the following factors:

Approval Agency Coverage: The 5HFP 2-R carries certifications from CCC, CE, CSA, cURus, IMQ, PSE, SEMKO, and VDE. The 0216002.MXEP (Littelfuse) provides the broadest certification coverage including CCC, CE, CSA, KC, SEMKO, UL, and VDE. The 0001.1007.PT (SCHURTER) carries cURus certification. The BK/S501-V-2-R (Eaton) includes BSI, CCC, CSA, cULus, IMQ, MITI/JET, SEMKO, and VDE certifications.

Inventory Availability: The 0001.1007.PT (SCHURTER) offers the highest inventory level at 4570 units. The 0216002.MXEP (Littelfuse) provides 1590 units, while the 5HFP 2-R (Bel Fuse) has 1508 units. The BK/S501-V-2-R (Eaton) has the lowest availability at 752 units.

Dimensional Tolerance: All parts conform to the 5mm x 20mm axial package specification. Minor dimensional variations exist within acceptable tolerances for through-hole mounting applications.

Frequently Asked Questions (FAQ)

Q: Can the 0001.1007.PT (SCHURTER) directly replace the 5HFP 2-R in all applications?

A: Yes. Both parts share identical electrical ratings (2 A, 250 V AC), fuse type (ceramic cartridge), response time (fast blow), and package dimensions (5mm x 20mm axial). The parts are functionally equivalent for through-hole circuit protection applications.

Q: What is the significance of the Melting I²t values shown in the comparison table?

A: Melting I²t represents the thermal energy required to melt the fuse element. The 5HFP 2-R has a Melting I²t of 3.8, while the substitute parts range from 1.87 to 2. These values fall within the acceptable range for 2 A fast-blow ceramic fuses and do not affect interchangeability for standard overcurrent protection applications.

Q: Are there any mechanical compatibility concerns when substituting these parts?

A: All parts are specified for 5mm x 20mm axial through-hole mounting. Physical dimensions show minor variations (e.g., 5.40mm to 5.80mm diameter, 21.00mm to 22.50mm length), but these fall within standard PCB footprint tolerances for axial component mounting.

Q: Which substitute part offers the best regulatory compliance coverage?

A: The 0216002.MXEP (Littelfuse) carries the most comprehensive certification set, including UL approval in addition to international standards. The BK/S501-V-2-R (Eaton) also provides extensive certifications including BSI and cULus. Selection should align with specific application regulatory requirements.

Q: Is DC Cold Resistance a critical parameter for substitution?

A: DC Cold Resistance values are provided for reference but do not affect functional interchangeability. The 5HFP 2-R specifies 0.052 Ohms, while substitutes range from 0.0764 to 0.073 Ohms. These variations are typical across ceramic fuse manufacturers and do not impact circuit protection performance.
