5SFP 10 Equivalent & Substitute Parts

Part Overview

The 5SFP 10 is a 10 A 250 V AC/DC fast-blow glass cartridge fuse with a 5mm x 20mm axial form factor, manufactured by Bel Fuse Inc. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and functional characteristics to ensure direct compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5SFP 10 are qualified based on the following mandatory 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) (exact match required)
• 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)

All three substitute parts meet these criteria and are therefore electrically and mechanically interchangeable with the 5SFP 10.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with current manufacturing status, providing supply continuity for the obsolete 5SFP 10. Selection should be based on the following factors:

5SFP 10-R (Bel Fuse Inc.): Direct manufacturer variant of the original part. Maintains Bel Fuse manufacturing lineage with ROHS3 compliance and cULus certification. Recommended for designs requiring continuity with the original manufacturer ecosystem.

0034.1526.PT (SCHURTER Inc.): SCHURTER FSF 5x20 series equivalent. Provides cURus, PSE/JET, and VDE certifications. Suitable for applications requiring European and Japanese regulatory compliance.

0217010.MXEP (Littelfuse Inc.): Littelfuse 217 series equivalent. Offers CE, K-MARK, and PSE certifications. Recommended for applications requiring Asian market compliance certifications.

All three parts are ROHS3 compliant and REACH unaffected, meeting modern environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 5SFP 10-R be used as a direct replacement for the 5SFP 10?

A: Yes. The 5SFP 10-R is electrically and mechanically identical to the 5SFP 10, with matching current rating (10 A), voltage rating (250 V), fuse type (cartridge glass), response time (fast blow), package dimensions (5mm x 20mm axial), and operating temperature range (-55°C ~ 125°C). The primary difference is product status: 5SFP 10-R is active while 5SFP 10 is obsolete.

Q: Are there dimensional differences between the substitute parts?

A: Minor dimensional variations exist. The 5SFP 10 and 5SFP 10-R are specified as 0.217" Dia x 0.827" L (5.50mm x 21.00mm). The 0034.1526.PT is 0.213" Dia x 0.886" L (5.40mm x 22.50mm). The 0217010.MXEP is 0.228" Dia x 0.886" L (5.80mm x 22.50mm). These variations remain within the 5mm x 20mm axial package classification and do not affect electrical performance or circuit compatibility.

Q: What is the difference in melting I²t values?

A: The 5SFP 10 has a melting I²t of 163, the 0034.1526.PT has 183, and the 0217010.MXEP has 217.635. All parts maintain the same 10 A current rating and fast-blow response time. These variations reflect different manufacturing processes and materials but do not affect functional compatibility in circuit applications.

Q: Which substitute part should be selected for new designs?

A: Selection depends on regulatory and certification requirements. For North American applications, 5SFP 10-R (cULus certified) is appropriate. For European applications, 0034.1526.PT (VDE certified) is suitable. For Asian market applications, 0217010.MXEP (K-MARK and PSE certified) is recommended. All three parts are ROHS3 compliant and REACH unaffected.

Q: Are all substitute parts available in bulk packaging?

A: Yes. The 5SFP 10-R, 0034.1526.PT, and 0217010.MXEP are all available in bulk packaging with current inventory levels of 1625, 1738, and 2400 pieces respectively.
