Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 0034.5228 is determined by strict alignment of the following parameters:

Current Rating: 1.5 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)
Size / Dimension: 0.250" Dia x 1.250" L (exact match required)
Breaking Capacity @ Rated Voltage: 100A (exact match required)

All substitute parts listed below meet these electrical and mechanical parameters. The SCHURTER 8020.5013 is excluded from direct substitution due to ceramic construction, higher voltage rating (500 V), and non-standard package format, despite similar current rating and response time characteristics.

Engineering Selection Recommendations

All listed substitute parts meet the electrical and mechanical requirements for direct replacement of the SCHURTER 0034.5228. Selection should prioritize active product status and compliance certifications:

Littelfuse 313 series parts (031301.5MXP, 031301.5HXP, 031301.5HXIDP, 031301.5VXIDP, 031301.5VXP) are active products with extended approval coverage including CE, CSA, PSE, and UL certifications. These components maintain the same operating temperature range (-55°C ~ 125°C) and breaking capacity as the original part.

Eaton MDL series parts (BK/MDL-1-1/2-R, MDL-1-1/2-R) are active products with CE, CSA, and UL approvals. Both variants meet all electrical and mechanical parameters and are suitable for direct substitution.

All substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 8020.5013 replace the 0034.5228?

A: No. Although both are slow-blow cartridge fuses, the 8020.5013 uses ceramic construction, operates at 500 V AC (versus 250 V), and uses a non-standard package format. These differences make it incompatible for direct substitution.

Q: What is the difference between Littelfuse 313 series variants (031301.5MXP, 031301.5HXP, 031301.5VXIDP, etc.)?

A: All Littelfuse 313 series variants listed meet identical electrical and mechanical parameters for the 0034.5228. Differences exist in packaging designations (MXP, HXP, VXIDP, VXP) and internal construction details not specified in the provided parameters. Selection among these variants should be based on availability and specific packaging requirements.

Q: Are Eaton MDL and BK/MDL variants interchangeable?

A: Yes. Both MDL-1-1/2-R and BK/MDL-1-1/2-R meet all electrical and mechanical requirements for substitution. The BK prefix indicates a specific packaging or distribution variant. Both are active products with identical electrical specifications.

Q: Does the operating temperature range differ between substitutes?

A: Littelfuse 313 series parts maintain the same operating temperature range as the original (-55°C ~ 125°C). Eaton MDL series parts do not specify an operating temperature range in the provided data. Verify temperature requirements for your specific application.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and REACH unaffected, maintaining regulatory alignment with the original SCHURTER 0034.5228.
