5HFP 5 Ceramic Fuse Equivalent & Substitute Parts

Part Overview

The 5HFP 5 is a 5A 250VAC ceramic cartridge fuse manufactured by Bel Fuse Inc., 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. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and approval certifications to ensure direct compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: current rating (5A), voltage rating (250VAC), fuse type (ceramic cartridge), response time (fast blow), breaking capacity (1.5kA), and mounting type (through hole). Physical dimensions and approval certifications are secondary factors that may vary within acceptable tolerances for the 5mm x 20mm form factor category.

The following parts meet these substitution criteria:

• 5HFP 5-R (Bel Fuse Inc.) – Direct manufacturer variant, active product status
• 0216005.MXEP (Littelfuse Inc.) – Equivalent electrical ratings, active product status
• 0216005.MXESPP (Littelfuse Inc.) – Equivalent electrical ratings, active product status

Parameter Comparison

Engineering Selection Recommendations

5HFP 5-R is the primary substitute for the obsolete 5HFP 5. Both parts are manufactured by Bel Fuse Inc. and share identical electrical specifications, dimensions, and DC cold resistance. The 5HFP 5-R holds active product status and achieves ROHS3 compliance, making it the direct replacement for new designs and ongoing production.

0216005.MXEP and 0216005.MXESPP (Littelfuse Inc.) are functionally equivalent alternatives. Both maintain the required 5A 250VAC ratings, fast-blow response, and 1.5kA breaking capacity. Physical dimensions vary slightly within the 5mm x 20mm form factor category. The 0216005.MXESPP offers the closest dimensional match to the original 5HFP 5 (5.20mm x 20.00mm). Both Littelfuse parts are ROHS3 compliant and carry active product status.

Selection between Bel Fuse and Littelfuse substitutes depends on approval agency requirements specific to the application. The 5HFP 5-R carries CSA and cULus certifications. The 0216005.MXEP carries BSI, KC, and UR certifications. The 0216005.MXESPP carries CQC certification. Verify that the selected substitute meets all required regulatory approvals for the target application.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts share identical current rating (5A), voltage rating (250VAC), fuse type (ceramic cartridge), response time (fast blow), breaking capacity (1.5kA), dimensions (5mm x 20mm), and DC cold resistance (0.016 Ohms). The 5HFP 5-R is the direct manufacturer variant with active product status.

Q: What are the dimensional differences between substitute parts?

A: The 5HFP 5 and 5HFP 5-R measure 5.50mm diameter x 21.00mm length. The 0216005.MXEP measures 5.80mm diameter x 22.50mm length. The 0216005.MXESPP measures 5.20mm diameter x 20.00mm length. All three fit the 5mm x 20mm form factor category for through-hole mounting.

Q: Do the Littelfuse substitutes have different electrical characteristics?

A: The Littelfuse parts (0216005.MXEP and 0216005.MXESPP) maintain the same current, voltage, and breaking capacity ratings. However, melting I²t differs: Bel Fuse parts specify 39, while Littelfuse parts specify 27.46. DC cold resistance is also slightly higher in Littelfuse parts (0.0183 Ohms vs. 0.016 Ohms). These differences remain within acceptable tolerance for the 5A 250VAC ceramic cartridge fuse category.

Q: Which substitute has the best regulatory compliance?

A: All three active substitutes (5HFP 5-R, 0216005.MXEP, 0216005.MXESPP) are ROHS3 compliant. Approval agency certifications differ: select based on application requirements. The 5HFP 5-R carries CSA and cULus certifications. The 0216005.MXEP carries the broadest certification set including BSI, KC, and UR. The 0216005.MXESPP carries CQC certification.

Q: Is the original 5HFP 5 still available?

A: The 5HFP 5 is classified as obsolete. Use 5HFP 5-R or Littelfuse equivalents for new procurement and designs.
