Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3101.0070 is determined by electrical and mechanical compatibility across the following critical parameters:

• Current Rating: 16 A (exact match required)
• Voltage Rating: 400V (exact match required)
• Fuse Size: 5mm x 20mm cartridge (exact match required)
• Number of Circuits: 1 (exact match required)
• Fuse Type: Cartridge (exact match required)
• Contact Material and Finish: Copper Alloy with Tin finish (exact match required)
• Regulatory Compliance: ROHS3 Compliant and REACH Unaffected (exact match required)

The primary distinction between the main part and its substitute relates to mounting technology and termination style. The 3101.0070 employs surface mount technology with gull wing termination, while substitute options may utilize alternative mounting configurations provided all electrical parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 3101.0055 serves as a direct electrical equivalent to the 3101.0070, maintaining identical current rating, voltage rating, fuse size, and circuit configuration. Both components are ROHS3 compliant and REACH unaffected, ensuring regulatory alignment.

The 3101.0055 holds active product status, providing supply chain continuity and long-term availability compared to the obsolete 3101.0070. The primary design consideration is the transition from surface mount gull wing termination to through hole PC pin termination. This substitution requires PCB layout modification to accommodate the different mounting technology and footprint.

Selection of the 3101.0055 is appropriate for applications where PCB redesign to through hole mounting is feasible and where the active product status provides manufacturing and support advantages.

Frequently Asked Questions (FAQ)

Q: Can the 3101.0055 be used as a direct replacement for the 3101.0070 without PCB modification?

A: No. The 3101.0070 uses surface mount gull wing termination, while the 3101.0055 uses through hole PC pin termination. PCB layout and footprint changes are required.

Q: Are the electrical specifications identical between these two parts?

A: Yes. Both components share identical current rating (16 A), voltage rating (400V), fuse size (5mm x 20mm), circuit count (1), and contact materials (copper alloy with tin finish).

Q: What is the significance of the product status difference?

A: The 3101.0070 is classified as obsolete, indicating discontinued production. The 3101.0055 maintains active status, ensuring ongoing availability, technical support, and supply chain reliability.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 3101.0070 and 3101.0055 are ROHS3 compliant and REACH unaffected, meeting equivalent environmental and regulatory standards.

Q: What is the primary design consideration when substituting these components?

A: The transition from surface mount to through hole mounting technology requires PCB redesign. The 3101.0055 uses PC pin termination suitable for through hole insertion, while the 3101.0070 uses gull wing termination for surface mount soldering.
