Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5SFP 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, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm x 20mm (axial) nominal dimensions (mechanical compatibility)
• Mounting Type: Through Hole (exact match required)
• Breaking Capacity @ Rated Voltage: 100 A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

All identified substitutes meet these criteria and are therefore electrically and mechanically interchangeable with the 5SFP 10-R in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—5SFP 10-R, 0034.1526.PT, and 0217010.MXEP—are active products with ROHS3 compliance and REACH unaffected status. Selection among these substitutes should be based on:

• Approval agency requirements: 5SFP 10-R carries CE, CSA, and cULus certifications; 0034.1526.PT carries cURus, PSE/JET, and VDE certifications; 0217010.MXEP carries CE, K-MARK, and PSE certifications. Choose the part whose certifications align with your application's regulatory requirements.

• Melting I²t characteristics: The three parts exhibit different melting I²t values (163, 183, and 217.635 respectively). Applications with specific thermal response requirements should account for these differences.

• Physical dimensions: While all parts fit the 5mm x 20mm nominal package, dimensional variations exist. Verify PCB footprint and mechanical clearance constraints.

• Availability: Current inventory levels are 1625 pcs (5SFP 10-R), 1738 pcs (0034.1526.PT), and 2400 pcs (0217010.MXEP).

Frequently Asked Questions (FAQ)

Q: Are these parts electrically interchangeable? A: Yes. All three parts share identical current rating (10 A), voltage rating (250 V AC), fuse type (cartridge glass), response time (fast blow), breaking capacity (100 A), and operating temperature range (-55°C ~ 125°C). They are electrically interchangeable for circuit protection applications.

Q: What are the physical differences between these parts? A: The parts have nominal 5mm x 20mm packages but differ in precise dimensions. The 5SFP 10-R measures 5.50mm diameter x 21.00mm length; the 0034.1526.PT measures 5.40mm diameter x 22.50mm length; the 0217010.MXEP measures 5.80mm diameter x 22.50mm length. Verify your PCB footprint accommodates these variations.

Q: Do these parts have different thermal response characteristics? A: Yes. The melting I²t values differ: 5SFP 10-R (163), 0034.1526.PT (183), and 0217010.MXEP (217.635). Applications with specific thermal response requirements should account for these differences when selecting a substitute.

Q: Which certifications does each part carry? A: 5SFP 10-R carries CE, CSA, and cULus certifications. 0034.1526.PT carries cURus, PSE/JET, and VDE certifications. 0217010.MXEP carries CE, K-MARK, and PSE certifications. Select the part whose certifications match your application's regulatory requirements.

Q: Are all parts RoHS compliant? A: Yes. All three parts are ROHS3 compliant and REACH unaffected.

Q: What is the difference in DC cold resistance? A: The 5SFP 10-R has 0.006 Ohms DC cold resistance; the 0217010.MXEP has 0.0063 Ohms. The 0034.1526.PT does not specify this parameter. For applications sensitive to resistance characteristics, the 5SFP 10-R offers the lowest value.
