SCHURTER 0034.7305 Equivalent & Substitute Parts

Part Overview

The SCHURTER 0034.7305 is a 100 mA, 250 V AC/DC board mount fuse with slow blow response characteristics, designed for through hole radial mounting in vertical orientation. This component is classified as active product status with full cULus approval. Equivalent parts are identified when identical electrical specifications and mechanical compatibility are maintained across the same fuse category, enabling direct substitution in circuit protection applications where the primary part becomes unavailable or inventory constraints require alternative sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 0034.7305 is determined by strict equivalence across the following critical parameters: current rating (100 mA), voltage rating (250 V AC), response time classification (Slow Blow), mounting configuration (Through Hole Radial, Can, Vertical), breaking capacity (50 A), and regulatory compliance (cULus approval). The Littelfuse 37401000000 meets all mandatory electrical and mechanical criteria for direct substitution. Both parts operate within the identical temperature range (-40°C ~ 85°C) and maintain ROHS3 compliance. Physical dimensions remain within acceptable tolerance for board mount applications, with the substitute part measuring 0.335" Dia x 0.315" H compared to the primary part's 0.335" Dia x 0.335" H.

Parameter Comparison

Engineering Selection Recommendations

Both the SCHURTER 0034.7305 and Littelfuse 37401000000 maintain active product status with full regulatory compliance. The Littelfuse part carries dual certification (CSA and cULus) compared to cULus-only certification for the SCHURTER part, providing expanded approval coverage. Both components satisfy ROHS3 compliance requirements and operate across the full -40°C to 85°C temperature range. Selection between these parts should be based on availability, lead time, and existing supply chain relationships, as electrical and mechanical performance characteristics are equivalent for board mount fuse applications.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse 37401000000 be used as a direct replacement for the SCHURTER 0034.7305?

A: Yes. Both parts share identical current rating (100 mA), voltage rating (250 V AC), response time (Slow Blow), mounting configuration (Through Hole Radial, Can, Vertical), and breaking capacity (50 A). Physical dimensions are compatible for standard PCB mounting applications.

Q: What are the key differences between these two fuses?

A: The primary differences are manufacturer identity and dimensional height tolerance. The Littelfuse part measures 0.315" H versus the SCHURTER part's 0.335" H, a 0.020" difference. The Littelfuse part carries additional CSA certification. Melting I²t values differ slightly (0.025 versus 0.0456), reflecting manufacturer-specific thermal characteristics within the slow blow classification.

Q: Are both parts ROHS3 compliant?

A: Yes. Both the SCHURTER 0034.7305 and Littelfuse 37401000000 are ROHS3 compliant and REACH unaffected.

Q: What is the operating temperature range for these fuses?

A: Both parts operate across -40°C to 85°C, suitable for industrial and commercial applications.

Q: Does the height difference affect PCB layout compatibility?

A: The 0.020" height difference (8.50mm versus 8.00mm) is within standard PCB clearance tolerances for radial through hole components. Verify specific board layout constraints for your application.

Q: What certifications apply to each part?

A: The SCHURTER 0034.7305 carries cULus approval. The Littelfuse 37401000000 carries both CSA and cULus approvals, providing broader regulatory acceptance across North American markets.
