Equivalent & Substitute Parts for 5HF 2 Ceramic Fuse

Part Overview

The 5HF 2 is a 2A 250VAC ceramic cartridge fuse manufactured by Bel Fuse Inc., designed for 5mm x 20mm holder-based applications. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing system maintenance and new designs. The fuse provides fast-blow response with 1.5kA breaking capacity and operates across -55°C to 125°C. Substitute parts maintain identical electrical ratings while offering improved availability and compliance status.

Substitute Part Grouping Explanation

Substitution for the 5HF 2 is determined by strict equivalence across the following parameters: current rating (2A), voltage rating (250VAC), fuse type (ceramic cartridge), physical package (5mm x 20mm), response time (fast blow), and breaking capacity (1.5kA). All substitute parts listed maintain these core electrical and mechanical specifications. Mounting type (requires holder) is preserved across all equivalents. Operating temperature range (-55°C to 125°C) is consistent across all alternatives. Substitutes are grouped by manufacturer and product status, with active-status parts prioritized over obsolete designations.

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete 5HF 2, the parametric equivalent 5HF 2-R from Bel Fuse Inc. is the primary selection. This part maintains identical mechanical and electrical specifications while offering active product status and ROHS3 compliance. The 5HF 2-R is suitable for holder-based installations matching the original design.

For new designs or applications where mounting flexibility is required, the 5HFP 2-R provides through-hole axial mounting while maintaining all core electrical parameters. This variant offers improved design flexibility with active status and ROHS3 compliance.

Cross-manufacturer alternatives from Littelfuse Inc. (0216002 series), SCHURTER Inc. (0001.1007), and Eaton (GDA-2A) provide equivalent electrical performance with active product status and full compliance certifications. These parts are suitable where multi-source qualification is required or where specific approval agency certifications are mandated by application standards.

All listed substitutes carry approval from major regulatory agencies including CCC, CE, CSA, PSE, SEMKO, UL, and VDE, ensuring compliance with international electrical safety standards.

Frequently Asked Questions (FAQ)

Q: Can I use 5HFP 2-R as a direct replacement for 5HF 2?

A: The 5HFP 2-R is electrically equivalent but differs in mounting type. The 5HF 2 requires a separate holder, while 5HFP 2-R features through-hole axial leads. Physical board layout and holder availability determine compatibility. If your application uses a 5x20mm fuse holder, use 5HF 2-R instead.

Q: What is the difference between Littelfuse 0216002.MXP and 0216002.HXP?

A: Both parts are electrically identical with 2A 250VAC ratings, 5x20mm package, and 1.5kA breaking capacity. Differences exist only in internal construction characteristics (melting I²t and DC cold resistance values are identical). Selection between these variants depends on specific application requirements or existing qualification documentation.

Q: Are all substitute parts RoHS compliant?

A: Yes. All active substitute parts listed carry ROHS3 compliance status. The original 5HF 2 is marked as RoHS non-compliant due to its obsolete status. Transition to any listed substitute ensures compliance with current environmental regulations.

Q: Can I mix different manufacturers in the same circuit?

A: All listed substitutes meet identical electrical specifications (2A, 250VAC, 1.5kA breaking capacity, fast-blow response). They are mechanically and electrically interchangeable within 5x20mm holder-based designs. Multi-source qualification is supported by consistent approval agency certifications across all parts.

Q: What does "requires holder" mean?

A: Cartridge fuses marked "requires holder" are cylindrical components that must be installed in a dedicated fuse holder or clip assembly. They are not soldered directly to circuit boards. Ensure your application includes the appropriate 5x20mm fuse holder before selecting these parts.

Q: How do melting I²t values affect substitution?

A: Melting I²t indicates the thermal energy required to melt the fuse element. The original 5HF 2 specifies 3.8, while Littelfuse variants specify 1.87. Both values fall within the fast-blow category for 2A fuses. Application-specific thermal requirements determine whether this variation is acceptable; consult circuit protection design specifications.
