SCHURTER 7091.1510 Fuse Holder Equivalent & Substitute Parts

Part Overview

The SCHURTER 7091.1510 is a cartridge fuse holder rated for 6.3 A at 250V, designed for single-circuit panel mount applications with 5mm x 20mm fuse compatibility. This part is classified as obsolete, making identification of active equivalent models essential for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical ratings and mechanical form factors to ensure direct functional replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7091.1510 is determined by strict equivalence across electrical and mechanical parameters. The primary substitution criteria are:

• Current Rating: Must be 6.3 A
• Voltage Rating: Must be 250V
• Fuse Size: Must accommodate 5mm x 20mm cartridge fuses
• Mounting Configuration: Must be panel mount with solder lug termination
• Circuit Count: Must be single circuit (1 circuit)

Based on these criteria, the SCHURTER 7091.3120 qualifies as a direct equivalent substitute. The 7093.0110, while manufactured by the same supplier and sharing identical voltage, mounting, and termination characteristics, operates at a different current rating (16 A) and accommodates a different fuse size (6.35mm x 32mm), making it unsuitable for direct substitution in applications requiring 6.3 A protection.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the obsolete 7091.1510, the SCHURTER 7091.3120 is the appropriate direct substitute. Both parts maintain identical electrical specifications (6.3 A, 250V) and mechanical compatibility (5mm x 20mm fuse accommodation). The 7091.3120 carries active product status and maintains full ROHS3 and REACH compliance, ensuring regulatory alignment for new designs and ongoing production.

The 7093.0110 is not suitable as a substitute for the 7091.1510 due to incompatible current and fuse size ratings. Selection of the 7093.0110 would require circuit redesign to accommodate its 16 A rating and 6.35mm x 32mm fuse format.

Frequently Asked Questions (FAQ)

Q: Can the 7091.3120 be used as a direct replacement for the 7091.1510?

A: Yes. Both parts share identical current rating (6.3 A), voltage rating (250V), fuse size (5mm x 20mm), mounting type (panel mount), and termination style (solder lug). The 7091.3120 is active and fully compliant with current regulatory standards.

Q: Why is the 7093.0110 listed but not recommended as a substitute?

A: The 7093.0110 operates at 16 A with 6.35mm x 32mm fuse accommodation, differing from the 7091.1510 specifications. Use of this part would alter circuit protection characteristics and require mechanical redesign of the fuse holder mounting interface.

Q: What packaging differences exist between the main part and substitute?

A: The 7091.1510 is supplied in standard packaging, while the 7091.3120 is packaged in boxes. Packaging format does not affect electrical or mechanical compatibility.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both the 7091.1510 and 7091.3120 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Q: What is the inventory status for the substitute part?

A: The 7091.3120 has 821 pieces in stock as new original inventory, supporting immediate procurement for replacement applications.
