Key Parameters

Substitute Part Grouping Explanation

Substitution of the 5HTP 5 ceramic cartridge fuse is determined by strict equivalence across the following critical parameters:

• Current Rating: 5 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
• Melting I²t: 101 (exact match required)

The 5HTP 5-R variant manufactured by Bel Fuse Inc. meets all substitution criteria and is classified as a direct equivalent. This substitute maintains identical electrical and mechanical specifications while offering active product status and improved compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 5HTP 5-R is the direct substitute for the obsolete 5HTP 5 ceramic cartridge fuse. Both parts maintain identical electrical performance specifications, dimensional compatibility, and thermal operating range. The 5HTP 5-R offers the advantage of active product status, ensuring continued availability and supply chain support. Additionally, the 5HTP 5-R achieves ROHS3 compliance, whereas the original 5HTP 5 is non-compliant. Both variants carry equivalent international approvals including CCC, CE, CSA, cULus, IMQ, PSE, SEMKO, and VDE certifications, confirming suitability for regulated applications. The negligible difference in DC cold resistance (0.019 Ohms versus 0.02 Ohms) does not impact functional performance in standard circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can the 5HTP 5-R be used as a direct replacement for the 5HTP 5?

A: Yes. The 5HTP 5-R is a direct equivalent. Both parts share identical current rating (5 A), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (slow blow), package dimensions (5mm x 20mm), and breaking capacity (1.5 kA). Physical and electrical compatibility is confirmed.

Q: What is the difference between the 5HTP 5 and 5HTP 5-R?

A: The primary differences are product status and compliance. The 5HTP 5 is obsolete and RoHS non-compliant, while the 5HTP 5-R is active and ROHS3 compliant. DC cold resistance differs marginally (0.019 Ohms versus 0.02 Ohms), which is not functionally significant for overcurrent protection applications.

Q: Are there any packaging differences between these parts?

A: The 5HTP 5 is available in standard packaging, while the 5HTP 5-R is supplied in bulk packaging. Both maintain identical component specifications and through-hole mounting form factor.

Q: Do both parts carry the same international certifications?

A: Yes. Both the 5HTP 5 and 5HTP 5-R hold identical approval certifications: CCC, CE, CSA, cULus, IMQ, PSE, SEMKO, and VDE. This ensures regulatory compliance across global markets.

Q: Is the 5HTP 5-R suitable for new designs?

A: Yes. The 5HTP 5-R is classified as active product status and is the recommended choice for new designs requiring a 5 A, 250 V AC ceramic cartridge fuse in 5mm x 20mm form factor with slow-blow response characteristics.
