Substitute Part Grouping Explanation

Substitution for the SCHURTER 0034.5217 is determined by strict equivalence across the following critical parameters:

• Current Rating: 375 mA (exact match required)
• Voltage Rating: 250 V AC (exact match required)
• Response Time: Slow Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Breaking Capacity: 35 A (exact match required)

All substitute parts listed below meet these criteria. Variations in secondary parameters such as melting I²t, DC cold resistance, and approval agencies do not affect functional substitutability within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are functionally equivalent to the SCHURTER 0034.5217 based on electrical and mechanical parameters. Selection among active alternatives should prioritize:

• Product Status: Littelfuse 0313.375HXP, 0313.375MXP, and 0313.375VXP are active products with current manufacturing support and extended availability.
• Eaton MDL-3/8-R and BK/MDL-3/8-R are active alternatives with equivalent electrical specifications and CSA/UL approval.
• Compliance: All substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the original part's environmental standards.
• Approval Certifications: Littelfuse alternatives include CE certification in addition to CSA and UL, providing broader regulatory coverage.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the SCHURTER 0034.5217?

A: Yes. All listed parts meet identical electrical specifications (375 mA, 250 V AC, slow-blow response) and mechanical requirements (3AB/3AG package, 1/4" x 1-1/4" dimensions). Physical installation in existing fuse holders is compatible.

Q: What is the difference between the Littelfuse 0313.375HXP, 0313.375MXP, and 0313.375VXP models?

A: These three Littelfuse parts share identical electrical and mechanical parameters. Differences exist only in internal construction details (melting I²t and DC cold resistance values), which do not affect substitutability for the specified application.

Q: Are the Eaton MDL-3/8-R and BK/MDL-3/8-R parts identical?

A: Both Eaton parts meet the same electrical and mechanical specifications. The BK/ prefix designation indicates a specific variant, but both are functionally equivalent for this application.

Q: Why is the SCHURTER 0034.5217 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. Active substitute parts from Littelfuse and Eaton provide equivalent functionality for new designs and system maintenance.

Q: Do all substitute parts have the same approval certifications?

A: All substitute parts carry CSA and UL approval. Littelfuse alternatives additionally include CE certification. The original SCHURTER part carries CSA and UL approval only.

Q: Can I mix different substitute parts in the same circuit or system?

A: Yes. All substitute parts are electrically and mechanically equivalent and can be used together in the same application without compatibility issues.
