Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 0218.160MXEP are qualified based on the following critical parameters:

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

All identified substitute parts meet these core electrical and mechanical specifications. Variations in secondary parameters such as melting I²t, DC cold resistance, and dimensional tolerances within the specified package envelope do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and meet the core electrical specifications for 160 mA, 250 V AC/DC slow-blow cartridge fuse applications. Selection among these substitutes should be based on:

• Approval Agency Requirements: The 0218.160MXEP carries CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE certifications. The 0034.3109.PT carries cURus certification. The 5STP 160-R carries CCC, CE, CSA, cULus, IMQ, SEMKO, and VDE certifications. Verify that the selected part meets the specific regulatory requirements of the target application.

• Inventory Availability: The 0034.3109.PT (SCHURTER) offers the highest inventory level at 4065 pieces. The 5STP 160-R (Bel Fuse) provides 1954 pieces, and the 0218.160MXEP (Littelfuse) provides 916 pieces.

• Dimensional Fit: While all parts conform to the 5mm x 20mm package specification, minor dimensional variations exist within the axial tolerance envelope. Verify mechanical fit within the target PCB or chassis mounting location.

Frequently Asked Questions (FAQ)

Q: Can the 0034.3109.PT or 5STP 160-R be used as direct replacements for the 0218.160MXEP?

A: Yes. All three parts share identical electrical specifications: 160 mA current rating, 250 V AC voltage rating, slow-blow response time, 35 A breaking capacity, and -55°C to 125°C operating temperature range. All are glass cartridge fuses in 5mm x 20mm through-hole packages. Substitution is valid from an electrical and mechanical standpoint.

Q: What are the key differences between these substitute parts?

A: The primary differences are manufacturer identity, approval agency certifications, and secondary parameters such as melting I²t and DC cold resistance. Dimensional variations within the 5mm x 20mm envelope also exist. These differences do not affect electrical performance for the specified application parameters.

Q: Are there any compliance or certification concerns when substituting parts?

A: Verify that the selected substitute part carries the regulatory certifications required by your application. The 0218.160MXEP includes UL certification, while the 0034.3109.PT does not. The 5STP 160-R includes cULus certification. Confirm certification alignment with your system requirements before final selection.

Q: Do dimensional variations affect mechanical compatibility?

A: All parts conform to the 5mm x 20mm axial package specification. Minor diameter and length variations exist within tolerance. Confirm that the selected part fits within your specific PCB or chassis mounting constraints, particularly if space is limited.

Q: What is the difference between melting I²t values across these parts?

A: Melting I²t is a secondary thermal characteristic that reflects the energy required to melt the fuse element. The provided values (0.219, 0.23, and 0.08) represent manufacturer-specific design variations. All parts meet the 160 mA, 250 V slow-blow specification and are electrically equivalent for the stated application parameters.
