Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 0034.2513 is determined by the following critical parameters:

• Current Rating: Must be 500 mA
• Voltage Rating - AC: Must be 250 V minimum
• Package / Case: Must be 5mm x 20mm
• Fuse Type: Must be Cartridge, Glass
• Mounting Type: Must require holder

All identified substitute parts meet these core electrical and mechanical requirements. Differences in response time (Medium Blow vs. Slow Blow), breaking capacity, melting I²t, and operating temperature ranges are secondary characteristics that may influence selection based on specific application requirements but do not disqualify substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Matching Response Time and Breaking Capacity):

The Littelfuse 20105000001 provides the closest electrical match to the SCHURTER 0034.2513, with identical current rating, AC voltage rating, medium blow response time, and 80 A breaking capacity. Both parts are ROHS3 compliant and active in production. The 20105000001 carries cULus certification and operates within -25°C to 70°C, which is narrower than the SCHURTER part but suitable for most standard applications.

Alternative Substitutes (Slow Blow Response):

The Littelfuse 0219.500MXAP offers the highest breaking capacity (150 A) among all substitutes while maintaining 500 mA current rating and 250 V AC voltage. This part is suitable for applications requiring enhanced fault current handling. The Littelfuse 0218.500MXP and 0214.600MXP provide standard slow blow characteristics with 35 A breaking capacity and extended operating temperature ranges (-55°C to 125°C), supporting broader environmental conditions than the main part.

The Bel Fuse 5ST 500-R delivers slow blow response with 35 A breaking capacity and comprehensive international certifications (CCC, CE, CSA, cURus, IMQ, SEMKO, VDE), making it suitable for globally distributed applications.

Selection Criteria:

• For applications requiring identical response time and breaking capacity: select Littelfuse 20105000001
• For applications tolerating slow blow response with extended temperature range: select Littelfuse 0218.500MXP or 0219.500MXAP
• For applications requiring maximum international certification coverage: select Bel Fuse 5ST 500-R

All substitute parts are active in production, ROHS3 compliant, and mechanically compatible with standard 5mm x 20mm fuse holders.

Frequently Asked Questions (FAQ)

Q: Can I substitute a Slow Blow fuse for the SCHURTER 0034.2513 Medium Blow fuse?

A: Substitution is mechanically and electrically possible since both share identical current rating (500 mA), AC voltage rating (250 V), and 5mm x 20mm package. However, response time differences affect circuit protection behavior. Slow Blow fuses tolerate higher inrush currents and are suitable for applications with transient current spikes. Medium Blow fuses provide faster response to sustained overcurrent conditions. Application requirements determine appropriateness.

Q: What is the significance of Breaking Capacity differences?

A: Breaking capacity indicates the maximum fault current a fuse can safely interrupt at rated voltage. The SCHURTER 0034.2513 has 80 A breaking capacity. Substitute parts range from 35 A to 150 A. Higher breaking capacity provides greater safety margin in high-fault-current environments. Lower breaking capacity is acceptable in applications with inherently limited fault current. System design determines minimum acceptable breaking capacity.

Q: Are all substitute parts compatible with existing fuse holders?

A: Yes. All substitute parts are 5mm x 20mm cartridge fuses requiring standard holders. Mechanical compatibility is confirmed. Electrical compatibility is verified through matching current and voltage ratings. Physical dimensions are consistent across all listed parts.

Q: Which substitute offers the widest operating temperature range?

A: The Littelfuse 0219.500MXAP, 0218.500MXP, 0214.600MXP, and Bel Fuse 5ST 500-R all operate from -55°C to 125°C, compared to the SCHURTER part's -40°C to 85°C range. These substitutes are suitable for applications requiring extended temperature performance.

Q: What certifications should I verify for my application?

A: Certification requirements depend on end-use application and regional standards. The SCHURTER 0034.2513 lists no specific approval agencies. Substitute parts carry certifications including UL, CE, CSA, VDE, CCC, and others. Verify that selected substitute certifications align with your application's regulatory requirements.
