SCHURTER 0034.5604.22 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0034.5604.22 is a 50 mA, 250 V AC/DC slow-blow glass cartridge fuse in a 5mm x 20mm form factor. This fuse is designed for circuit protection applications requiring a slow-blow response characteristic and operates across a temperature range of -55°C to 125°C. The part is actively manufactured and holds ROHS3 compliance with cURus and VDE approvals. Substitute parts are identified to provide alternative sourcing options while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0034.5604.22 are qualified based on the following electrical and mechanical parameters:

• Current Rating: 50 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Package / Case: 5mm x 20mm (exact match required)
• Response Time: Slow Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 35 A (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)

The Littelfuse 0218.050HXP meets all specified electrical and mechanical parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 0034.5604.22 and Littelfuse 0218.050HXP are active products with ROHS3 compliance. The Littelfuse substitute carries additional regulatory approvals (CCC, CE, CSA, K-MARK, SEMKO, UL) beyond the SCHURTER part's cURus and VDE certifications. Selection between these parts should be based on application-specific regulatory requirements and supply chain considerations. Both parts are electrically and mechanically equivalent for the specified 50 mA, 250 V AC/DC slow-blow cartridge fuse application.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0218.050HXP be used as a direct replacement for the SCHURTER 0034.5604.22?

A: Yes. Both parts share identical electrical ratings (50 mA, 250 V AC/DC), fuse type (cartridge, glass), physical dimensions (5mm x 20mm), response characteristic (slow blow), and operating temperature range (-55°C ~ 125°C).

Q: Are there packaging differences between these parts?

A: The SCHURTER 0034.5604.22 is supplied in Tape & Reel (TR) packaging, while the Littelfuse 0218.050HXP is supplied in Bulk packaging. Both are suitable for holder-based mounting applications.

Q: What regulatory approvals apply to each part?

A: The SCHURTER part carries cURus and VDE approvals. The Littelfuse substitute carries CCC, CE, CSA, K-MARK, SEMKO, UL, and VDE approvals. Application requirements determine which approval set is necessary.

Q: Are the melting I²t values equivalent?

A: The melting I²t values differ between parts (SCHURTER: 0.0363; Littelfuse: 0.00692). Both parts meet the 35 A breaking capacity specification at rated voltage and maintain the slow-blow response characteristic across the operating temperature range.

Q: Can these fuses be used without a holder?

A: No. Both parts require a holder for mounting and operation.
