SCHURTER 0034.6071 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0034.6071 is a 500 mA, 250 V AC/DC board mount fuse with fast blow response time, designed for through-hole radial mounting in a vertical can configuration. This component is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Equivalent and substitute parts are identified when design requirements permit tolerance in current rating or when sourcing from alternative manufacturers becomes necessary due to inventory constraints or supply chain considerations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0034.6071 are classified based on the following electrical and mechanical parameters that determine functional interchangeability:

Critical Parameters for Substitution:

• Voltage Rating (AC): 250 V (must match exactly)
• Mounting Type: Through Hole (must match exactly)
• Package / Case: Radial, Can, Vertical (must match exactly)
• Response Time: Fast Blow (must match exactly)
• Operating Temperature Range: -40°C ~ 85°C (must match exactly)
• Breaking Capacity @ Rated Voltage: 35 A (must match exactly)

Allowable Variation:

• Current Rating: Substitutes with higher current ratings (630 mA) are acceptable when circuit design permits, as they provide equivalent or superior protection characteristics within the same voltage and breaking capacity envelope.

Direct Equivalent: Littelfuse 37005000000 matches all critical parameters including current rating (500 mA).

Similar Substitute: Littelfuse 37006300000 matches all critical parameters except current rating (630 mA vs. 500 mA), suitable for applications where higher current tolerance is acceptable.

Parameter Comparison

Engineering Selection Recommendations

Littelfuse 37005000000 (Direct Equivalent): This part is the primary substitute for the SCHURTER 0034.6071. It maintains identical electrical specifications (500 mA, 250 V, fast blow response) and mechanical form factor. Both parts carry Active product status, ROHS3 compliance, and REACH unaffected designation. The Littelfuse part includes additional international approvals (CCC, cURus, SEMKO, VDE), providing broader regulatory coverage. Height dimension variance (0.315" vs. 0.335") is within typical PCB layout tolerances for through-hole radial components.

Littelfuse 37006300000 (Similar Substitute): This part is suitable for applications where circuit design permits a higher current rating (630 mA). It maintains all critical electrical parameters (250 V, 35 A breaking capacity, fast blow response, -40°C ~ 85°C operating range) and mechanical mounting characteristics. Selection of this substitute requires confirmation that the higher current rating does not compromise circuit protection intent. Both Littelfuse parts share identical regulatory compliance status with the original SCHURTER component.

Frequently Asked Questions (FAQ)

Q: Can Littelfuse 37006300000 (630 mA) be used in place of SCHURTER 0034.6071 (500 mA)?

A: Littelfuse 37006300000 is electrically and mechanically compatible with the SCHURTER 0034.6071 in terms of voltage rating, breaking capacity, response time, and mounting configuration. However, the higher current rating (630 mA vs. 500 mA) means the fuse will tolerate greater current before activation. Use this substitute only when circuit design analysis confirms that the higher current threshold does not compromise protection requirements.

Q: What is the significance of the height dimension difference between SCHURTER 0034.6071 (0.335" H) and Littelfuse substitutes (0.315" H)?

A: The 0.020" (0.50mm) height difference is within standard PCB layout tolerances for through-hole radial components. Both parts maintain identical 0.335" diameter and radial mounting configuration. Verify PCB clearance and component spacing during board layout to confirm accommodation of the slightly shorter Littelfuse parts.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The SCHURTER 0034.6071 and both Littelfuse substitutes (37005000000 and 37006300000) are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What additional certifications do the Littelfuse substitutes provide?

A: Littelfuse 37005000000 and 37006300000 carry international approvals including CCC, cURus, SEMKO, and VDE, whereas the SCHURTER 0034.6071 lists no specific approval agency. These additional certifications may be beneficial for applications requiring specific regional or industry compliance documentation.

Q: Can the Littelfuse parts be used interchangeably with each other?

A: Littelfuse 37005000000 and 37006300000 are not interchangeable due to different current ratings (500 mA vs. 630 mA). Selection between these two parts depends on circuit protection requirements. The 500 mA part (37005000000) provides equivalent protection to the original SCHURTER component, while the 630 mA part (37006300000) is suitable only when higher current tolerance is acceptable by design.
