SCHURTER 7091.1520 Cartridge Fuse Holder - Equivalent & Substitute Parts

Part Overview

The SCHURTER 7091.1520 is a single-circuit cartridge fuse holder rated for 6.3 A at 250V, designed for panel mount applications with 5mm x 20mm fuse compatibility. This part is classified as obsolete, making identification of active equivalent models essential for procurement and design continuity. Substitute parts must maintain identical electrical ratings and mechanical compatibility to ensure proper circuit protection and installation fit.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7091.1520 are identified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

• Current Rating: 6.3 A (exact match required)
• Voltage Rating: 250V (exact match required)
• Fuse Size: 5mm x 20mm (exact match required)
• Number of Circuits: 1 (exact match required)
• Mounting Type: Panel Mount (exact match required)
• Termination Style: Solder Lug (exact match required)
• RoHS Compliance: ROHS3 Compliant (maintained)

The SCHURTER 7091.3120 meets all substitution criteria as an active product with identical electrical and mechanical specifications. The SCHURTER 7093.0110, while manufactured by the same supplier, operates at a different current rating (16 A) and fuse size (6.35mm x 32mm), making it unsuitable as a direct substitute for the 7091.1520.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 7091.3120 is the qualified substitute for the obsolete 7091.1520. Both parts maintain identical electrical specifications (6.3 A, 250V) and mechanical compatibility (5mm x 20mm fuse size, panel mount, solder lug termination). The 7091.3120 carries active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment.

The SCHURTER 7093.0110 is not suitable as a substitute due to incompatible current rating (16 A versus 6.3 A) and fuse size (6.35mm x 32mm versus 5mm x 20mm). Application of this part would result in incorrect circuit protection characteristics and mechanical incompatibility with existing fuse inventory.

Frequently Asked Questions (FAQ)

Q: Can the 7091.3120 be used as a direct replacement for the 7091.1520?

A: Yes. The 7091.3120 maintains identical electrical ratings (6.3 A, 250V), fuse size (5mm x 20mm), mounting configuration (panel mount), and termination style (solder lug). Both parts are ROHS3 compliant and suitable for equivalent circuit protection applications.

Q: Why is the 7093.0110 listed as a non-compatible substitute?

A: The 7093.0110 operates at 16 A with a 6.35mm x 32mm fuse size, differing from the 7091.1520 specifications of 6.3 A and 5mm x 20mm. These differences prevent mechanical and electrical compatibility. Using this part would alter circuit protection characteristics and require different fuse inventory.

Q: What packaging options are available for the substitute part?

A: The 7091.3120 substitute is available in box packaging, while the original 7091.1520 packaging specification is not defined. Both parts are supplied as new original stock from SCHURTER Inc.

Q: Are there compliance or regulatory differences between the main part and substitute?

A: Both the 7091.1520 and 7091.3120 are ROHS3 compliant and REACH unaffected. Regulatory compliance is maintained across the substitution.
