Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Littelfuse 23015000021 is determined by strict alignment with the following critical parameters: current rating (5 A), voltage rating (250 V AC), fuse type (ceramic cartridge), physical package dimensions (5mm x 20mm), and response time classification (fast blow). The substitute part must maintain compatibility with standard 5x20mm fuse holders and preserve the electrical protection characteristics of the original design. Compliance certifications (ROHS3, REACH Unaffected) and product status (Active) further validate substitution viability.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 0034.0908 qualifies as a direct substitute for the Littelfuse 23015000021 based on matching electrical ratings (5 A, 250 V AC), identical fuse type classification (ceramic cartridge), and compatible physical dimensions (5mm x 20mm). Both components maintain Active product status and satisfy ROHS3 and REACH compliance requirements. The SCHURTER part demonstrates enhanced breaking capacity (1.5 kA versus 1 kA) and an extended operating temperature range (-40°C to 85°C versus -25°C to 70°C), providing additional performance margin in demanding thermal environments. Component selection should be based on application-specific temperature requirements and available inventory.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0034.0908 be used as a direct replacement for the Littelfuse 23015000021?

A: Yes. Both components share identical current ratings (5 A), voltage ratings (250 V AC), fuse type (ceramic cartridge), and physical package dimensions (5mm x 20mm). Both require standard 5x20mm fuse holders and exhibit fast-blow response characteristics.

Q: What are the key differences between these two fuses?

A: The SCHURTER part offers higher breaking capacity (1.5 kA versus 1 kA) and a wider operating temperature range (-40°C to 85°C versus -25°C to 70°C). These differences do not affect substitution eligibility but may provide performance advantages in specific applications.

Q: Are both fuses compliant with environmental regulations?

A: Yes. Both the Littelfuse 23015000021 and SCHURTER 0034.0908 are ROHS3 compliant and REACH unaffected, meeting current environmental standards for electronic components.

Q: Do these fuses require special holders or adapters?

A: Both fuses are ceramic cartridge types requiring standard 5mm x 20mm fuse holders. No special adapters are necessary for interchangeability.

Q: Which fuse should be selected for high-temperature applications?

A: The SCHURTER 0034.0908 is rated for operation up to 85°C, compared to 70°C for the Littelfuse part. For applications exceeding 70°C ambient temperature, the SCHURTER component is the appropriate selection.
