5HFP 1 Ceramic Fuse - Equivalent & Substitute Parts

Part Overview

The 5HFP 1 is a 1 A, 250 V AC/DC ceramic cartridge fuse with fast-blow response characteristics, designed for through-hole mounting in 5mm x 20mm form factor. This part is classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement. The fuse is rated for breaking capacity of 1.5 kA and operates across -55°C to 125°C temperature range with multiple international certifications including UL, CE, and CSA.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 5HFP 1 is determined by strict equivalence across the following critical parameters: current rating (1 A), voltage rating (250 V AC), fuse type (ceramic cartridge), response time (fast blow), package dimensions (5mm x 20mm), breaking capacity (1.5 kA), and mounting configuration (through hole). All substitute parts listed maintain these core electrical and mechanical specifications. Parametric equivalents are active-status parts from the same manufacturer series. Direct manufacturer equivalents from alternative suppliers (SCHURTER, Littelfuse) provide identical functional performance with different part numbering schemes. The 5HF 1.25-R variant differs in current rating (1.25 A) and is listed as a reference point only; it does not qualify as a direct substitute due to higher current specification.

Parameter Comparison

Engineering Selection Recommendations

For new designs and ongoing procurement, 5HFP 1-R is the primary substitute, offering identical electrical and mechanical specifications with active product status and ROHS3 compliance from the original manufacturer Bel Fuse Inc. This part maintains full backward compatibility with existing through-hole mounting configurations.

For applications requiring multi-source qualification, 0216001.MXEP (Littelfuse 216 series) and 0216001.MXESPP (Littelfuse 216SP series) provide functionally equivalent alternatives with active status and expanded international certifications (CCC, CE, CSA, KC, PSE, SEMKO, UL, VDE for MXEP; CE, CSA, CQC, KC, PSE, UR, VDE for MXESPP). Both Littelfuse parts are ROHS3 compliant.

0001.1004.PT (SCHURTER SP 5x20 series) is suitable where SCHURTER-qualified components are required, with cURus certification and ROHS3 compliance.

All substitute parts maintain the 1.5 kA breaking capacity and fast-blow response time required for circuit protection in the original application.

Frequently Asked Questions (FAQ)

Q: Can 5HF 1.25-R be used as a substitute for 5HFP 1?

A: No. The 5HF 1.25-R has a current rating of 1.25 A, which exceeds the 1 A specification of the 5HFP 1. Using a higher-rated fuse compromises circuit protection and violates the original design specification.

Q: What is the difference between 5HFP 1-R and the original 5HFP 1?

A: Both parts are electrically and mechanically identical with matching current rating (1 A), voltage (250 V), package (5mm x 20mm), and breaking capacity (1.5 kA). The primary difference is product status: 5HFP 1 is obsolete while 5HFP 1-R is active. Additionally, 5HFP 1-R is ROHS3 compliant, whereas the original is non-compliant.

Q: Are Littelfuse 0216001.MXEP and 0216001.MXESPP interchangeable?

A: Both parts meet the core electrical specifications (1 A, 250 V, fast-blow, 1.5 kA breaking capacity) and 5mm x 20mm package requirements. Physical dimensions vary slightly (MXEP: 5.80mm diameter x 22.50mm length; MXESPP: 5.20mm diameter x 20.00mm length). Verify mechanical fit within the specific fuse holder or socket before substitution.

Q: Which substitute offers the broadest international certification coverage?

A: 0216001.MXEP (Littelfuse 216 series) carries certifications from CCC, CE, CSA, KC, PSE, SEMKO, UL, and VDE, providing the widest geographic and standards compliance coverage among the listed substitutes.

Q: Is SCHURTER 0001.1004.PT suitable for UL-regulated applications?

A: 0001.1004.PT carries cURus certification, which covers both Canadian (cUL) and U.S. (UL) requirements. It is suitable for UL-regulated applications.
