Substitute Part Grouping Explanation

Substitution of the SCHURTER 0034.3417 is determined by strict equivalence across the following parameters:

Current Rating: 1 A (exact match required)
Voltage Rating (AC): 250 V (exact match required)
Fuse Type: Cartridge, Glass (exact match required)
Response Time: Slow Blow (exact match required)
Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
Physical Dimensions: 0.250" Dia x 1.250" L (exact match required)

All substitute parts listed below meet these criteria and are classified as either direct manufacturer equivalents or parametric equivalents with active product status.

Engineering Selection Recommendations

All listed substitute parts meet the electrical and mechanical parameters of the SCHURTER 0034.3417. Selection should prioritize active product status and compliance requirements:

Littelfuse 313 Series (0313001.MXP, 0313001.HXC932P, 0313001.HXIDP, 0313001.HXP, 0313001.VXIDP, 0313001.VXP) are active products with ROHS3 compliance and extended approval agency certifications (CE, CSA, PSE, UL). These parts provide the broadest regulatory support for new designs and ongoing procurement.

Eaton BK/MDQ-1 is an active product with CSA and UL certifications. This part does not carry ROHS3 compliance and should be selected only where RoHS exemptions are applicable or where legacy system compatibility is required.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 0034.3417 be directly replaced with any of the listed substitutes?

A: Yes. All listed substitute parts are electrically and mechanically equivalent, meeting identical specifications for current rating (1 A), voltage rating (250 V AC), fuse type (cartridge glass), response time (slow blow), and physical dimensions (0.250" Dia x 1.250" L). All are compatible with 3AB and 3AG fuse holders.

Q: What is the difference between the Littelfuse 313 Series variants?

A: The Littelfuse 313 Series variants (0313001.MXP, 0313001.HXC932P, 0313001.HXIDP, 0313001.HXP, 0313001.VXIDP, 0313001.VXP) are parametric equivalents with identical electrical and mechanical specifications. Differences exist in internal construction characteristics (DC cold resistance values) and packaging configurations, but all meet the same functional requirements for the SCHURTER 0034.3417 application.

Q: Should I select a ROHS3-compliant part?

A: ROHS3 compliance is required for products destined for European markets and many regulated applications. All Littelfuse 313 Series parts carry ROHS3 compliance. The Eaton BK/MDQ-1 does not. Selection depends on your application's regulatory requirements.

Q: Are there any voltage or current rating differences between substitutes?

A: No. All substitute parts are rated for 1 A at 250 V AC/DC with identical breaking capacity (35A) and operating temperature range (-55°C ~ 125°C).

Q: What approval agencies certify these parts?

A: The original SCHURTER 0034.3417 carries CSA certification. Littelfuse 313 Series parts carry CE, CSA, PSE, and UL certifications. Eaton BK/MDQ-1 carries CSA and UL certifications. Verify that the selected substitute meets your application's specific certification requirements.
