Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5HF 500 is determined by strict equivalence across the following parameters:

• Current Rating: 500 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity: 1.5 kA (exact match required)
• Mounting Type: Requires Holder (exact match required)

All substitute parts listed below meet these core electrical and mechanical parameters. Variations in DC cold resistance, melting I²t values, and dimensional tolerances within the 5mm x 20mm envelope are permitted within industry standards for ceramic fuse cartridges.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: 5HF 500-R (Bel Fuse Inc.)

The 5HF 500-R is the direct parametric equivalent from the original manufacturer. It maintains identical electrical specifications, mounting requirements, and physical dimensions while offering active product status and ROHS3 compliance. This part is the preferred choice for direct replacement in existing designs.

Secondary Recommendations: Littelfuse 0216 Series (0216.500HXP, 0216.500MXBP, 0216.500MXP, 0216.500TXP, 0216.500VXP)

All Littelfuse 0216 series parts meet the core electrical and mechanical parameters. These parts carry active product status and ROHS3 compliance with broader certification coverage (CCC, CE, CSA, SEMKO, UR, VDE). Selection among these variants should be based on specific application certifications required and inventory availability.

Alternative Recommendation: S501-500-R (Eaton - Electronics Division)

The S501-500-R provides equivalent electrical performance with active status and ROHS3 compliance. Eaton certification includes BSI, CCC, CSA, cURus, IMQ, SEMKO, and VDE, offering broad regulatory acceptance.

Mounting Consideration: 5HFP 500-R (Bel Fuse Inc.)

The 5HFP 500-R differs in mounting type (through-hole axial vs. requires holder) and physical dimensions (5.50mm diameter x 21.00mm length). This part is suitable only for applications where through-hole mounting is specified and holder-based mounting is not required.

Frequently Asked Questions (FAQ)

Q: Can I use 5HFP 500-R as a direct replacement for 5HF 500?

A: No. While both parts share identical electrical ratings (500 mA, 250 V, fast blow), the 5HFP 500-R uses through-hole axial mounting and has different physical dimensions (5.50mm x 21.00mm vs. 5.10mm x 20.00mm). The 5HF 500 requires a separate holder. Use 5HFP 500-R only if your application is designed for through-hole axial mounting.

Q: What is the difference between the Littelfuse 0216 variants?

A: All Littelfuse 0216 variants (0216.500HXP, 0216.500MXBP, 0216.500MXP, 0216.500TXP, 0216.500VXP) meet identical electrical and mechanical specifications for the 500 mA, 250 V, 5mm x 20mm ceramic cartridge fuse. Differences are internal design variations within the same product category. Selection should be based on application-specific certification requirements and supplier availability.

Q: Are all substitute parts RoHS compliant?

A: The 5HF 500 (obsolete) is RoHS non-compliant. All active substitute parts listed are ROHS3 compliant except GDA-500MA, for which RoHS status is not specified. Verify GDA-500MA compliance with your supplier if RoHS certification is required.

Q: What certifications apply to these fuses?

A: The original 5HF 500 carries CCC, CE, CSA, and UL approvals. Active substitutes carry broader certification coverage. Littelfuse 0216 series and S501-500-R include CCC, CE, CSA, SEMKO, UR, and VDE. Eaton GDA-500MA includes CCC, CSA, IMQ, and SEMKO. Select based on your application's regulatory requirements.

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

A: Yes. All listed parts meet identical electrical parameters (500 mA, 250 V, fast blow, 1.5 kA breaking capacity) and physical form factor (5mm x 20mm). They are mechanically and electrically interchangeable within the same holder assembly. However, maintain consistency within a single design for quality control and traceability purposes.

Q: What is the significance of DC cold resistance variations?

A: DC cold resistance values range from 0.34 Ohms to 0.866 Ohms across the substitute parts. These variations reflect internal design differences but do not affect fuse operation at rated current and voltage. All values are within acceptable limits for ceramic cartridge fuses in this category.
