Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5HFP 5-R is determined by strict equivalence across the following 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: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

All three substitute parts listed below meet these core electrical and mechanical criteria. Variations in physical dimensions, melting I²t values, DC cold resistance, and approval agency certifications do not preclude substitution when the above parameters are satisfied.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the 5HFP 5-R based on electrical and mechanical parameters. Selection should be based on the following factors:

0216005.MXEP (Littelfuse) offers the highest inventory availability at 65,100 pieces and is supplied in bulk packaging, making it suitable for high-volume production requirements.

0216005.MRET1P (Littelfuse) is available in cut tape packaging with 2,400 pieces in stock, appropriate for automated assembly processes and moderate-volume applications.

0216005.MXESPP (Littelfuse) is supplied in bulk with 1,200 pieces in stock and represents the most compact physical form factor at 5.20mm diameter x 20.00mm length.

All substitute parts maintain active product status and ROHS3 compliance. Approval agency certifications vary slightly between manufacturers but cover standard industrial and regional requirements (CCC, CE, CSA, PSE, VDE, UR, KC).

Frequently Asked Questions (FAQ)

Q: Can 0216005.MXEP be used as a direct replacement for 5HFP 5-R?

A: Yes. Both parts share identical electrical ratings (5 A, 250 V AC), fuse type (ceramic cartridge), response time (fast blow), mounting configuration (through hole), and breaking capacity (1.5 kA). Physical dimensions differ slightly but remain within the 5mm x 20mm axial package specification.

Q: What is the difference between the three Littelfuse substitutes?

A: The primary differences are packaging format and physical dimensions. 0216005.MRET1P uses cut tape packaging suitable for pick-and-place assembly. 0216005.MXEP and 0216005.MXESPP are bulk-packaged; 0216005.MXESPP has a slightly smaller diameter (5.20mm vs. 5.80mm). All three are electrically identical.

Q: Are there compliance or certification differences between the main part and substitutes?

A: The 5HFP 5-R carries eight approval agencies (CCC, CE, CSA, cULus, IMQ, PSE, SEMKO, VDE). Littelfuse substitutes carry between seven and eight agencies with slight variations. All parts meet standard industrial compliance requirements for their respective markets.

Q: Does melting I²t value affect substitution suitability?

A: Melting I²t is a secondary thermal characteristic. The 5HFP 5-R specifies 39, while Littelfuse parts specify 27.46. Both values are within acceptable ranges for 5 A fast-blow ceramic fuses and do not preclude substitution when primary electrical parameters match.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the circuit design accommodates the specified electrical parameters (5 A, 250 V, fast-blow response, 1.5 kA breaking capacity). Physical mounting dimensions are compatible with standard 5mm x 20mm axial fuse holders.
