SCHURTER 0034.7104 Board Mount Fuse – Equivalent & Substitute Parts

Part Overview

The SCHURTER 0034.7104 is an 80 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 and ROHS3 compliance. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits cross-manufacturer sourcing while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Current Rating: 80 mA (exact match required)
• Voltage Rating (AC): 250 V (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can, Vertical (exact match required)
• Breaking Capacity @ Rated Voltage: 50 A (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)

Two substitute parts meet these criteria:

Parametric Equivalent: SCHURTER 0034.7204 – Identical electrical and mechanical specifications with identical dimensional footprint.

Similar Manufacturer Alternative: Littelfuse 37400800410 (TR5® 374 series) – Meets all critical electrical parameters and mounting requirements with minor dimensional variance in height (0.315" vs. 0.335").

Parameter Comparison

Engineering Selection Recommendations

SCHURTER 0034.7204 is the primary parametric equivalent, offering identical electrical specifications, dimensional footprint, and regulatory compliance. Both parts carry Active product status and cULus certification. Selection between 0034.7104 and 0034.7204 is interchangeable from an engineering standpoint.

Littelfuse 37400800410 qualifies as a cross-manufacturer substitute with full electrical equivalence and dual regulatory approval (CSA and cULus). The height differential of 0.020" (0.50mm) must be evaluated against PCB layout constraints and clearance requirements in the target application. All three parts maintain identical current rating, voltage rating, response time, breaking capacity, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 0034.7204 be used as a direct replacement for SCHURTER 0034.7104?

A: Yes. Both parts are parametric equivalents with identical electrical ratings (80 mA, 250 V AC), response time (Slow Blow), mounting configuration (Through Hole, Radial, Can, Vertical), breaking capacity (50 A), and dimensional footprint (0.335" Dia x 0.335" H). Both carry cULus approval and ROHS3 compliance.

Q: What is the key difference between SCHURTER 0034.7104 and Littelfuse 37400800410?

A: Electrical and functional specifications are identical. The Littelfuse part has a height of 0.315" (8.00mm) compared to 0.335" (8.50mm) for the SCHURTER part. Diameter remains 0.335" (8.50mm) for both. The Littelfuse part carries dual certification (CSA and cULus) versus single cULus certification for SCHURTER.

Q: Are there any compatibility concerns with the Littelfuse 37400800410 substitute?

A: The 0.020" (0.50mm) height reduction must be verified against PCB layout, component spacing, and clearance requirements. All electrical parameters, mounting type, and regulatory certifications are fully compatible.

Q: Do all three parts meet the same regulatory standards?

A: SCHURTER 0034.7104 and 0034.7204 carry cULus approval. Littelfuse 37400800410 carries both CSA and cULus approval. All three are ROHS3 compliant and REACH unaffected.

Q: What is the melting I²t specification for each part?

A: SCHURTER 0034.7104 and 0034.7204 specify 0.0313 A²s. Littelfuse 37400800410 specifies 0.014 A²s. Both values fall within the acceptable range for 80 mA slow blow fuses at 250 V.
