Equivalent & Substitute Parts for 5HFP 8 Ceramic Fuse

Part Overview

The 5HFP 8 is an 8A 250VAC ceramic cartridge fuse manufactured by Bel Fuse Inc., designed for through-hole mounting in 5mm x 20mm form factor applications. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance requirements. Active alternatives from Bel Fuse Inc., Littelfuse Inc., and SCHURTER Inc. provide direct functional equivalence while maintaining current product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (8A), voltage rating (250VAC), fuse type (cartridge ceramic), response time (fast blow), breaking capacity (1.5kA), and operating temperature range (-55°C to 125°C). All identified substitutes meet these core electrical specifications. Physical dimensions vary within acceptable tolerances for the 5mm x 20mm form factor category. Melting I²t values and DC cold resistance differ among manufacturers but remain within the functional envelope for this application class.

Parameter Comparison

Engineering Selection Recommendations

5HFP 8-R is the primary direct substitute, manufactured by Bel Fuse Inc. with identical electrical specifications and melting I²t characteristics. This part maintains active product status and achieves ROHS3 compliance, addressing the RoHS non-compliance of the obsolete 5HFP 8.

0216008.MXESPP (Littelfuse Inc., Series 216SP) offers the closest physical dimensions (5.20mm x 20.00mm) to the original specification and provides the highest inventory availability (4762 units). This part carries CE, CSA, CQC, PSE, and UR certifications.

0216008.MXEP (Littelfuse Inc., Series 216) provides equivalent electrical performance with broader certification coverage including TUV and KC approvals, supporting applications requiring expanded regulatory compliance.

0001.1013.PT (SCHURTER Inc., Series SP 5x20) is suitable for applications where cURus certification is the primary compliance requirement. Physical dimensions are 5.40mm x 22.50mm, representing the largest variant within the 5mm x 20mm category tolerance.

All substitutes maintain the 1.5kA breaking capacity and -55°C to 125°C operating temperature range required for functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can 5HFP 8-R directly replace 5HFP 8 in existing designs?

A: Yes. 5HFP 8-R maintains identical current rating (8A), voltage rating (250VAC), response time (fast blow), breaking capacity (1.5kA), and melting I²t (126). Both are ceramic cartridge fuses in 5mm x 20mm form factor with through-hole mounting. The primary difference is product status (active vs. obsolete) and RoHS compliance.

Q: What are the physical dimension tolerances for substitution?

A: All substitutes conform to the 5mm x 20mm (axial) package category. Measured dimensions range from 5.20mm to 5.80mm diameter and 20.00mm to 22.50mm length. These variations remain within acceptable mechanical tolerances for standard through-hole fuse holders designed for this form factor.

Q: How do melting I²t differences affect substitution suitability?

A: Melting I²t values (ranging from 64.315 to 126 across the substitute group) indicate thermal response characteristics. All parts share the fast-blow response classification and 8A current rating. Differences in I²t reflect manufacturer-specific ceramic and element design but do not prevent functional substitution within the same current and voltage class.

Q: Which substitute offers the best regulatory compliance coverage?

A: 0216008.MXEP (Littelfuse Inc.) provides the broadest certification set: CE, CSA, KC, PSE, SEMKO, TUV, and UR. Selection should align with specific application regulatory requirements.

Q: Are there inventory considerations for substitute selection?

A: 0216008.MXESPP maintains the highest stock level (4762 units), followed by 5HFP 8-R (1840 units) and 0216008.MXEP (2100 units). 0001.1013.PT has 845 units available.
