Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for ceramic cartridge fuses is determined by strict equivalence across the following parameters:

• Current Rating: Must be exactly 4 A
• Voltage Rating (AC): Must be exactly 250 V
• Fuse Type: Must be Cartridge, Ceramic
• Response Time: Must be Fast Blow
• Package / Case: Must be 5mm x 20mm (Axial)
• Mounting Type: Must be Through Hole
• Breaking Capacity @ Rated Voltage: Must be 1.5kA
• Operating Temperature Range: Must support -55°C ~ 125°C

The substitute part 5HFP 4-R meets all mandatory electrical and mechanical parameters, confirming direct substitutability with the primary part 0216004.MXEP.

Parameter Comparison

Engineering Selection Recommendations

Both 0216004.MXEP and 5HFP 4-R are active products with ROHS3 compliance and equivalent electrical ratings. Selection between these parts should be based on:

• Availability and lead time requirements
• Manufacturer certifications: 0216004.MXEP carries CCC, CE, CSA, KC, PSE, SEMKO, UL, VDE approvals; 5HFP 4-R carries CCC, CE, CSA, cULus, IMQ, PSE, SEMKO, VDE approvals
• Physical dimensions: 0216004.MXEP measures 0.228" Dia x 0.886" L; 5HFP 4-R measures 0.217" Dia x 0.827" L (minor dimensional variation within through-hole mounting tolerance)
• Inventory availability: 0216004.MXEP has 2800 pcs in stock; 5HFP 4-R has 2849 pcs in stock

Frequently Asked Questions (FAQ)

Q: Can 5HFP 4-R be used as a direct replacement for 0216004.MXEP in existing designs?

A: Yes. Both parts meet identical electrical specifications (4A, 250VAC, Fast Blow, 1.5kA breaking capacity) and share the same 5mm x 20mm through-hole package. Minor dimensional variations (0.011" diameter difference, 0.059" length difference) remain within standard through-hole mounting tolerances.

Q: Are there differences in approval certifications between these parts?

A: Both parts carry overlapping certifications (CCC, CE, CSA, PSE, SEMKO, VDE). 0216004.MXEP includes KC and UL; 5HFP 4-R includes cULus and IMQ. Verify certification requirements for your specific application region.

Q: What is the significance of the different Melting I²t values (14.995 vs 22)?

A: Melting I²t indicates the thermal energy required to melt the fuse element. Both values confirm fast-blow response characteristics appropriate for 4A protection. The difference reflects manufacturing variations between Littelfuse and Bel Fuse designs while maintaining equivalent functional performance.

Q: Are both parts RoHS compliant?

A: Yes. Both 0216004.MXEP and 5HFP 4-R are ROHS3 compliant and REACH unaffected.
