Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the SCHURTER 0031.1657 is determined by the following critical parameters:

• Fuse Size Compatibility: Both the main part and substitute must accommodate 5mm x 20mm cartridge fuses
• Mounting Configuration: Panel mount orientation must be maintained
• Circuit Count: Single-circuit functionality must be preserved
• Fuse Type: Cartridge fuse holder classification must match
• Regulatory Compliance: ROHS3 and REACH compliance status must be equivalent or superior
• Contact Material and Finish: Copper alloy construction ensures electrical performance consistency

The Littelfuse 82000000005 qualifies as a functional equivalent based on these parameters. While termination style differs (quick connect versus solder lug), the core electrical and mechanical compatibility with 5mm x 20mm fuses remains intact, allowing substitution in applications where termination method can be accommodated.

Engineering Selection Recommendations

The Littelfuse 82000000005 represents the primary equivalent for the obsolete SCHURTER 0031.1657. Selection should be based on the following factors:

Product Status: The SCHURTER part is obsolete, while the Littelfuse alternative maintains active production status, ensuring long-term availability and supply chain continuity.

Regulatory Compliance: Both components meet ROHS3 and REACH requirements, confirming environmental and hazardous substance compliance equivalence.

Mechanical Compatibility: Identical fuse size (5mm x 20mm), mounting type (panel mount), and circuit count (1) ensure direct functional replacement in existing designs.

Termination Consideration: The substitute employs quick connect termination (0.187" / 4.7mm) rather than solder lug. Circuit board layout and connector compatibility must be evaluated during integration.

Electrical Performance: Copper alloy contact construction in both components provides equivalent electrical conductivity and reliability characteristics.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 82000000005 directly replace the SCHURTER 0031.1657 in existing assemblies?

A: Mechanical and electrical compatibility is confirmed for 5mm x 20mm fuse cartridge accommodation. Termination method differs (quick connect versus solder lug), requiring verification that the circuit board or connector interface supports the quick connect terminal configuration.

Q: What is the significance of the obsolete product status for the SCHURTER part?

A: Obsolete status indicates discontinued manufacturing. The Littelfuse 82000000005 is actively produced, providing assured availability for replacement units and new production requirements.

Q: Are there voltage or current rating differences between these parts?

A: The Littelfuse substitute specifies 250V and 6.3A ratings. The SCHURTER part does not provide explicit voltage or current specifications in the available data. Applications requiring specific voltage or current ratings must confirm compatibility with the Littelfuse ratings.

Q: Do both parts meet the same environmental compliance standards?

A: Yes. Both components are ROHS3 compliant and REACH unaffected, confirming equivalent environmental and regulatory compliance.

Q: What packaging considerations apply to these fuse holders?

A: The SCHURTER part is available in standard packaging, while the Littelfuse substitute is supplied in bulk packaging. Procurement quantities and storage requirements should be evaluated accordingly.
