SCHURTER 0034.1007 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0034.1007 is a 5A 250VAC fast-blow glass cartridge fuse in 3AB/3AG package format (1/4" x 1-1/4"). This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance and procurement planning. The fuse requires a compatible holder for installation and operates across a temperature range of -40°C to 85°C with a breaking capacity of 1.5kA at rated voltage.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SCHURTER 0034.1007 is determined by strict alignment of the following critical parameters:

• Current Rating: 5 A (exact match required)
• Package / Case: 3AB, 3AG, 1/4" x 1-1/4" (exact match required for holder compatibility)
• Response Time: Fast Blow (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (minimum requirement)
• Breaking Capacity @ Rated Voltage: 1.5kA (minimum requirement)
• Size / Dimension: 0.250" Dia x 1.252" L (exact match required)

Voltage rating may be elevated in substitutes, provided all other parameters remain compatible. Fuse construction material (glass vs. ceramic) and series designation do not prevent substitution when all electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

SCHURTER 8020.5075 is the primary substitute for the 0034.1007. This ceramic cartridge fuse maintains all critical mechanical and electrical parameters: 5A current rating, fast-blow response, 3AB/3AG package compatibility, 1.5kA breaking capacity, and identical physical dimensions. The elevated voltage rating of 500VAC provides enhanced margin in applications originally specified for 250VAC operation. The part is currently active in production with cURus approval certification, ensuring long-term availability and compliance support.

SCHURTER 0001.1031 is a parametric equivalent offering identical electrical specifications and package format. This glass fuse cartridge matches the 0034.1007 in current rating, voltage, response time, and mechanical dimensions. However, both the main part and this equivalent are classified as obsolete. The 0001.1031 should be considered only when the 8020.5075 ceramic construction is not acceptable for the application.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 8020.5075 directly replace the 0034.1007 in existing applications?

A: Yes. The 8020.5075 maintains identical current rating (5A), response time (fast-blow), package format (3AB/3AG), breaking capacity (1.5kA), and physical dimensions (0.250" Dia x 1.252" L). The elevated voltage rating (500VAC vs. 250VAC) does not prevent substitution and provides additional safety margin. Both fuses are compatible with the same holder.

Q: What is the difference between the glass and ceramic construction in these fuses?

A: The 0034.1007 and 0001.1031 use glass construction, while the 8020.5075 uses ceramic construction. Both materials meet the same electrical and mechanical specifications for this application. Material selection does not affect compatibility with standard 3AB/3AG holders.

Q: Why is the melting I²t value different between these parts?

A: Melting I²t reflects the thermal energy required to melt the fuse element and is influenced by construction material and element design. Despite differences in I²t values (13, 32, and 33.2), all three parts share identical current ratings, voltage ratings, and response times, making them functionally equivalent for circuit protection purposes.

Q: Is the 0001.1031 a viable long-term substitute?

A: The 0001.1031 is classified as obsolete, similar to the main part. While it provides parametric equivalence, the SCHURTER 8020.5075 is the recommended choice due to its active production status and cURus certification, ensuring sustained availability and regulatory compliance.

Q: Are there any compliance or certification differences between these substitutes?

A: The 8020.5075 carries cURus approval certification. The 0034.1007 and 0001.1031 do not list approval agency certifications. All three parts are ROHS3 compliant and REACH unaffected. For applications requiring specific certifications, the 8020.5075 is the appropriate selection.
