5SF 160 Glass Cartridge Fuse – Equivalent & Substitute Parts

Part Overview

The 5SF 160 is a 160 mA, 250 V AC/DC fast-blow glass cartridge fuse manufactured by Bel Fuse Inc. in a 5mm × 20mm form factor. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs. The fuse requires a dedicated holder for installation and is designed for circuit protection applications requiring fast response characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 5SF 160 is determined by strict alignment with the following electrical and mechanical parameters:

• Current Rating: 160 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 5mm × 20mm (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Mounting Type: Requires Holder (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)
• Operating Temperature Range: −55°C to 125°C (exact match required)

All substitute parts listed below meet these criteria. Substitutes are categorized as direct equivalents (functionally identical across all specified parameters) or similar alternatives (meeting all core electrical and mechanical requirements with minor variations in secondary characteristics such as DC cold resistance or melting I²t values).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts satisfy the core electrical and mechanical requirements for direct replacement of the 5SF 160. Selection should prioritize active product status to ensure long-term availability and supply chain continuity.

For new designs and applications requiring regulatory compliance, ROHS3-compliant alternatives are available: 0034.1508 (SCHURTER Inc.), 0217.160MXBP, 0217.160MXP, 0217.160TXP, and 0217.160VXP (all Littelfuse Inc.), and S500-160-R (Eaton - Electronics Division). These parts maintain full electrical and mechanical equivalence while meeting current environmental standards.

The Littelfuse 217 series (0217.160MXBP, 0217.160MXP, 0217.160TXP, 0217.160VXP) and SCHURTER FSF 5×20 series (0034.1508) offer the broadest certification coverage, including CCC, CE, CSA, SEMKO, UL, and VDE approvals. Eaton GDB and S500 series alternatives provide active product status with established supply availability.

Frequently Asked Questions (FAQ)

Q: Can the 5SF 160 be directly replaced with any of the listed substitute parts?

A: Yes. All substitute parts listed meet the mandatory electrical and mechanical parameters: 160 mA current rating, 250 V AC voltage rating, fast-blow response, 5mm × 20mm package, 35 A breaking capacity, and −55°C to 125°C operating temperature range. Physical dimensions and holder compatibility are identical across all alternatives.

Q: What is the difference between direct equivalents and similar alternatives?

A: All parts listed meet the core substitution criteria. Variations exist in secondary characteristics such as DC cold resistance (ranging from 2.5 to 9.1 Ohms) and melting I²t values (ranging from 0.008 to 0.0113). These differences do not affect functional compatibility for standard circuit protection applications.

Q: Are there compliance differences between substitute options?

A: Yes. The 5SF 160 is RoHS non-compliant and obsolete. Active alternatives include ROHS3-compliant options (0034.1508, 0217.160MXBP, 0217.160MXP, 0217.160TXP, 0217.160VXP, S500-160-R) and non-RoHS-specified options (GDB-160MA). Certification coverage varies by manufacturer; Littelfuse and SCHURTER parts carry broader international approvals (CCC, CE, CSA, SEMKO, UL, VDE).

Q: Does the 5mm × 20mm package dimension apply to all substitutes?

A: Yes. All substitute parts use the identical 5mm × 20mm cartridge form factor and require the same holder type. Physical interchangeability is guaranteed.

Q: Which substitute offers the best long-term availability?

A: Littelfuse 217 series parts (0217.160MXBP, 0217.160MXP, 0217.160TXP, 0217.160VXP) and SCHURTER 0034.1508 are active products with established supply chains and broad certification coverage, making them suitable for new designs and ongoing production.
