SCHURTER 0034.6807 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0034.6807 is a 160 mA board mount fuse rated for 250 V AC and 125 V DC operation. This slow blow fuse features a radial, can-style vertical package and is designed for through-hole mounting on printed circuit boards. The part is currently active in production with 1,881 pieces available in inventory. Equivalent and substitute parts are identified when they maintain the same current rating, voltage specifications, response time characteristics, and mounting configuration while meeting applicable regulatory approvals.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0034.6807 are qualified based on the following critical parameters:

• Current Rating: Must be 160 mA
• Voltage Rating - AC: Must be 250 V minimum
• Response Time: Must be Slow Blow
• Mounting Type: Must be Through Hole
• Package / Case: Must be Radial, Can, Vertical configuration
• Fuse Type: Must be Board Mount (Cartridge Style Excluded)

The Littelfuse 37201600001 meets all primary electrical and mechanical substitution criteria. It maintains the 160 mA current rating, 250 V AC voltage specification, slow blow response time, through-hole mounting, and radial can vertical package configuration. Minor dimensional variations and operating temperature range differences do not preclude substitution when the application environment is within the substitute part's rated limits.

The Bel Fuse MRT 5-BULK does not qualify as a direct substitute due to its 5 A current rating, which is significantly higher than the required 160 mA specification. This part is listed in the original substitute field but represents a different functional category and should not be used as a replacement for the 160 mA requirement.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 37201600001 is the qualified substitute for the SCHURTER 0034.6807 when the application environment operates within -40°C to 85°C. Both parts carry CCC, cURus, and VDE approvals, ensuring compliance with major regulatory frameworks. The Littelfuse part maintains identical current rating, voltage specification, response time, and package configuration. Dimensional height variation (8.00mm versus 8.50mm) is within typical PCB layout tolerances for radial through-hole components.

Applications requiring operation below -40°C or above 85°C should retain the SCHURTER 0034.6807, which supports the full -55°C to 125°C range. The SCHURTER part also includes KC approval, which may be required for specific regional markets.

The Bel Fuse MRT 5-BULK is not suitable as a substitute due to its 5 A current rating specification, which does not meet the 160 mA requirement of the original design.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 37201600001 be used as a direct replacement for the SCHURTER 0034.6807?

A: Yes, the Littelfuse 37201600001 qualifies as a direct substitute when the application operates within the -40°C to 85°C temperature range. Both parts share the same 160 mA current rating, 250 V AC voltage specification, slow blow response time, through-hole mounting, and radial can vertical package. Regulatory approvals (CCC, cURus, VDE) are equivalent.

Q: What is the significance of the melting I²t difference between the SCHURTER and Littelfuse parts?

A: The melting I²t value (0.24 for SCHURTER versus 0.1792 for Littelfuse) indicates the thermal energy required to melt the fuse element. The Littelfuse part melts at lower energy levels, which may result in faster response in certain fault conditions. Both parts maintain the same 160 mA current rating and slow blow classification, but circuit designers should verify that the substitute part's thermal characteristics are acceptable for the specific application.

Q: Why is the Bel Fuse MRT 5-BULK listed as a substitute but not recommended?

A: The Bel Fuse MRT 5-BULK is listed in the original part's substitute field but carries a 5 A current rating, which is 31 times higher than the required 160 mA specification. This part represents a different functional category and would not provide the same circuit protection. It should not be used as a replacement.

Q: Are there dimensional compatibility concerns with the Littelfuse substitute?

A: The Littelfuse 37201600001 has a height of 8.00mm compared to the SCHURTER 0034.6807 at 8.50mm. This 0.50mm difference is within standard PCB layout tolerances for radial through-hole components and does not typically present mechanical compatibility issues. Verify clearance in your specific PCB design if space constraints exist.

Q: What approvals does each part carry?

A: SCHURTER 0034.6807 carries CCC, cURus, KC, and VDE approvals. Littelfuse 37201600001 carries CCC, cURus, SEMKO, and VDE approvals. Both parts meet major regulatory requirements. The SCHURTER part includes KC approval for Korean markets, while the Littelfuse part includes SEMKO approval for Nordic markets.
