Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5HFP 10-R are qualified based on the following critical parameters:

• Current Rating: 10 A (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Package / Case: 5mm x 20mm (Axial) (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 1.5 kA (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

All identified substitute parts meet these core electrical and mechanical parameters. Variations in physical dimensions (diameter and length tolerances), melting I²t values, DC cold resistance, and approval agency certifications are secondary considerations that do not affect functional interchangeability within the specified electrical operating envelope.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are active products with ROHS3 compliance and are electrically and mechanically interchangeable with the 5HFP 10-R within the specified operating parameters.

0001.1014.PT (SCHURTER Inc.): Approved by cURus. Suitable for applications requiring SCHURTER certification. Physical dimensions (5.40mm x 22.50mm) fall within acceptable tolerance for 5mm x 20mm axial packages.

0216010.MRET1P (Littelfuse Inc.): Supplied in Cut Tape (CT) packaging. Approved by CE, CSA, ICC, PSE, SEMKO, TUV, UR. Suitable for high-volume automated assembly processes. Physical dimensions (5.80mm x 22.50mm) are within tolerance.

0216010.MXEP (Littelfuse Inc.): Supplied in Bulk packaging. Approved by CCC, CE, CSA, K-MARK, PSE, SEMKO, UL. Broadest approval agency coverage. Physical dimensions (5.80mm x 22.50mm) are within tolerance.

0216010.MXESPP (Littelfuse Inc.): Supplied in Bulk packaging. Approved by CE, CSA, CQC, PSE, UR. Physical dimensions (5.20mm x 20.00mm) most closely match the original 5HFP 10-R specification.

Selection among substitute parts should be based on supply availability, packaging requirements, and required approval agency certifications for the end application.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts for the 5HFP 10-R without circuit redesign?

A: Yes. All substitute parts meet the core electrical parameters (10 A, 250 V AC, 1.5 kA breaking capacity, fast-blow response) and mechanical specifications (5mm x 20mm axial through-hole package). No circuit redesign is required.

Q: What is the significance of the different melting I²t values?

A: Melting I²t indicates the thermal energy required to melt the fuse element. The 5HFP 10-R has a melting I²t of 227, while Littelfuse substitutes have 154.34. Both values are within the fast-blow category for 10 A fuses. The difference reflects manufacturing variations between suppliers but does not affect functional compatibility in standard circuit protection applications.

Q: Are there physical dimension differences I should consider?

A: Yes. The 0216010.MXESPP (5.20mm x 20.00mm) most closely matches the original 5HFP 10-R (5.50mm x 21.00mm). The 0001.1014.PT and 0216010.MRET1P/MXEP are slightly longer (22.50mm). All dimensions remain within the 5mm x 20mm axial package classification and are compatible with standard fuse holders designed for this form factor.

Q: Which substitute should I choose for high-volume production?

A: The 0216010.MRET1P is supplied in Cut Tape (CT) packaging, optimized for automated assembly. The 0216010.MXEP and 0216010.MXESPP are supplied in Bulk packaging, suitable for manual or semi-automated processes.

Q: Do all substitutes have the same approval certifications?

A: No. The 0216010.MXEP has the broadest approval coverage (CCC, CE, CSA, K-MARK, PSE, SEMKO, UL). The 0001.1014.PT is approved by cURus only. Select the substitute based on the specific certifications required by your application and regional regulations.

Q: What is the difference between DC cold resistance values?

A: The 5HFP 10-R has 0.006 Ohms, while Littelfuse substitutes have 0.0079 Ohms. This minor difference reflects internal element design variations and does not affect circuit protection performance in standard applications.
