SCHURTER 0034.7117 Board Mount Fuse – Equivalent & Substitute Parts

Part Overview

The SCHURTER 0034.7117 is a 1.6 A, 250 V AC/DC board mount fuse with slow blow response characteristics, designed for through-hole radial mounting in vertical orientation. This component is classified as Active product status with full cULus approval. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits cross-manufacturer sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment of the following critical parameters:

• Current Rating: 1.6 A (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: 50 A (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Approval Agency: cULus or equivalent (CSA + cULus acceptable)

Two substitute parts meet these criteria: SCHURTER 0034.7217 (parametric equivalent from same manufacturer) and Littelfuse 37411600410 (similar part from alternative manufacturer). Both maintain identical electrical performance and mechanical compatibility with the main part number.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain Active product status with full regulatory compliance. SCHURTER 0034.7217 is a direct parametric equivalent within the same manufacturer's MSTU 250 series, offering identical electrical and mechanical specifications. Littelfuse 37411600410 from the TR5® 374 series provides cross-manufacturer compatibility with dual CSA and cULus approvals, though height dimension differs by 0.020" (0.50mm). All parts are ROHS3 compliant and suitable for applications requiring -40°C to 85°C operating temperature range. Selection between these parts depends on supply availability, inventory levels, and design flexibility regarding minor dimensional variations.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 0034.7217 be used as a direct replacement for SCHURTER 0034.7117?

A: Yes. Both parts are parametric equivalents with identical current rating (1.6 A), voltage rating (250 V), response time (Slow Blow), mounting type (Through Hole), package configuration (Radial, Can, Vertical), breaking capacity (50 A), and operating temperature range (-40°C ~ 85°C). They are electrically and mechanically interchangeable.

Q: Is the Littelfuse 37411600410 compatible with designs using SCHURTER 0034.7117?

A: Electrical compatibility is confirmed. All critical parameters match: 1.6 A current rating, 250 V voltage rating, Slow Blow response, Through Hole mounting, Radial Can Vertical package, and 50 A breaking capacity. The height dimension is 0.315" (8.00mm) versus 0.335" (8.50mm) for the SCHURTER part. Verify PCB layout clearance before substitution.

Q: What are the key parameters that determine substitution eligibility?

A: Current rating, voltage rating, response time, mounting type, package configuration, breaking capacity, and operating temperature range must match exactly. Approval agency certifications (cULus or CSA + cULus) must be present. Minor dimensional variations are acceptable if PCB layout permits.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SCHURTER 0034.7117, SCHURTER 0034.7217, and Littelfuse 37411600410 are all ROHS3 compliant.

Q: What is the difference in melting I²t between the main part and Littelfuse substitute?

A: SCHURTER 0034.7117 has melting I²t of 17.5, while Littelfuse 37411600410 has melting I²t of 4.5. This parameter difference does not affect substitution eligibility based on the specified criteria, but may influence thermal response characteristics in specific circuit applications.
