Substitute Part Grouping Explanation

Substitution for the SCHURTER 0034.5147 is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Current Rating: 15 A (exact match required)
• Voltage Rating (AC): 125 V (exact match required)
• Fuse Type: Cartridge, Glass (exact match required)
• Response Time: Fast Blow (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required)
• Breaking Capacity @ Rated Voltage: 10 kA (exact match required)

Secondary Compatibility Factors:

• Operating Temperature Range: -55°C ~ 125°C (must encompass or match)
• Physical Dimensions: 0.250" Dia x 1.252" L (must be compatible with holder)
• Regulatory Compliance: CSA, UL approval (or equivalent certifications)

The Bel Fuse Inc. 3AG 15-R meets all primary and secondary criteria and is classified as a parametric equivalent. The Littelfuse 0312015.MXP does not qualify as a direct substitute due to reduced voltage rating (32V AC versus 125V AC), which restricts its application scope.

Parameter Comparison

Engineering Selection Recommendations

Bel Fuse Inc. 3AG 15-R is the direct parametric equivalent for the SCHURTER 0034.5147. This substitute maintains identical electrical ratings (15A, 125VAC), response characteristics (fast-blow), breaking capacity (10kA), and physical dimensions. The part is currently in active production status, ensuring long-term availability. Regulatory certifications include CSA and cURus, providing broader geographic compliance coverage than the original part. This substitute is suitable for direct replacement in all applications where the SCHURTER 0034.5147 was originally specified.

Littelfuse 0312015.MXP is not recommended as a substitute for the SCHURTER 0034.5147 due to voltage rating mismatch (32V AC versus 125V AC). While the current rating and package format are identical, the reduced voltage rating restricts this part to lower-voltage applications and does not satisfy the electrical requirements of circuits designed for 125VAC operation.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 0312015.MXP be used in place of the SCHURTER 0034.5147?

A: No. The Littelfuse part has a maximum voltage rating of 32V AC, while the SCHURTER part is rated for 125V AC. Using a lower-voltage fuse in a higher-voltage circuit creates a safety hazard and violates electrical design standards.

Q: What makes the Bel Fuse 3AG 15-R a suitable substitute?

A: The Bel Fuse 3AG 15-R matches all critical parameters: 15A current rating, 125V AC voltage rating, fast-blow response, 10kA breaking capacity, and 3AB/3AG package format with identical physical dimensions. It is currently in active production and holds equivalent regulatory certifications.

Q: Are there any dimensional differences between the SCHURTER 0034.5147 and the Bel Fuse 3AG 15-R?

A: Both parts share the same package designation (3AB, 3AG, 1/4" x 1-1/4") and identical physical dimensions (0.250" Dia x 1.252" L). They are mechanically interchangeable in standard fuse holders.

Q: Does the Bel Fuse 3AG 15-R require a different holder?

A: No. Both the SCHURTER 0034.5147 and Bel Fuse 3AG 15-R use the same 3AB/3AG holder format. Existing holders are compatible without modification.

Q: What is the significance of the 10kA breaking capacity rating?

A: Breaking capacity indicates the maximum fault current the fuse can safely interrupt without rupturing or creating a hazard. Both the SCHURTER and Bel Fuse parts are rated for 10kA, ensuring equivalent protection performance in circuits with identical fault current levels.

Q: Are both substitute options RoHS compliant?

A: Yes. The SCHURTER 0034.5147, Bel Fuse 3AG 15-R, and Littelfuse 0312015.MXP are all ROHS3 compliant, meeting environmental and material restriction requirements for electronic components.
