SCHURTER 0034.6813 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0034.6813 is a 630 mA board mount fuse rated for 250 V AC and 63 V DC operation with slow blow response characteristics. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and new design implementations. The fuse features radial, can-style vertical mounting for through-hole PCB applications with a breaking capacity of 35 A AC and 50 A DC.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 0034.6813 is determined by the following critical parameters:

• Current Rating: 630 mA (exact match required)
• Voltage Rating - AC: 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can, Vertical (exact match required)
• Breaking Capacity @ Rated Voltage: Minimum 35 A AC (exact match or higher acceptable)

The Littelfuse 37206300001 satisfies all primary substitution criteria. This part maintains identical current rating, AC voltage rating, response time, mounting configuration, and package style. The breaking capacity of 35 A AC meets the minimum requirement. Both components are ROHS3 compliant and carry equivalent international safety certifications.

Parameter Comparison

Engineering Selection Recommendations

The Littelfuse 37206300001 is the qualified substitute for the obsolete SCHURTER 0034.6813. Both components meet identical electrical specifications for current rating, AC voltage rating, and response time characteristics. The substitute maintains through-hole radial mounting compatibility and equivalent breaking capacity at rated voltage.

The Littelfuse part carries active product status with current manufacturing support, whereas the SCHURTER part is obsolete. Both components satisfy ROHS3 compliance requirements and carry recognized international safety certifications including CCC, cURus, and VDE approval.

Physical dimensions differ slightly in height (0.335" versus 0.315"), which remains within typical PCB layout tolerances for radial through-hole components. The operating temperature range of the substitute (-40°C ~ 85°C) is narrower than the original part (-55°C ~ 125°C); applications requiring extended temperature operation below -40°C or above 85°C must evaluate this limitation against system requirements.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 37206300001 be used as a direct replacement in existing designs?

A: Yes. The substitute maintains identical current rating (630 mA), AC voltage rating (250 V), response time (Slow Blow), mounting type (Through Hole), and package style (Radial, Can, Vertical). Physical height differs by 0.020" (0.50mm), which is acceptable for standard PCB layouts.

Q: What are the key differences between these parts?

A: The primary differences are product status (Littelfuse is active; SCHURTER is obsolete), operating temperature range (Littelfuse: -40°C ~ 85°C; SCHURTER: -55°C ~ 125°C), and minor physical height variation (0.020" difference). Electrical performance and safety certifications are equivalent.

Q: Are there any DC voltage rating considerations?

A: The original SCHURTER part specifies 63 V DC rating. The Littelfuse substitute does not specify a separate DC voltage rating in the provided data. Applications requiring explicit DC voltage rating confirmation should reference the Littelfuse TR5® 372 series technical documentation.

Q: What certifications apply to the substitute part?

A: The Littelfuse 37206300001 carries CCC, cURus, SEMKO, and VDE approvals. Both components are ROHS3 compliant and REACH unaffected.

Q: Is the packaging format compatible with automated assembly?

A: The Littelfuse substitute is supplied in Cut Tape (CT) packaging, suitable for automated pick-and-place assembly operations. The original SCHURTER part packaging format is not specified in the provided data.
