Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 0034.7110 are classified based on strict electrical and mechanical parameter alignment:

Parametric Equivalent Classification: Parts maintaining identical specifications across all critical parameters including current rating (315 mA), voltage rating (250 V AC), response time (Slow Blow), mounting type (Through Hole), package configuration (Radial, Can, Vertical), breaking capacity (50A), and operating temperature range (-40°C ~ 85°C).

Similar Manufacturer Classification: Parts from alternative manufacturers meeting the same electrical specifications and mechanical compatibility requirements, with allowable variations in secondary parameters such as melting I²t values, DC cold resistance, or dimensional tolerances within functional equivalence.

The following parameters are mandatory for substitution eligibility:

• Current Rating: 315 mA
• Voltage Rating (AC): 250 V
• Response Time: Slow Blow
• Mounting Type: Through Hole
• Fuse Type: Board Mount (Cartridge Style Excluded)
• Package / Case: Radial, Can, Vertical
• Breaking Capacity @ Rated Voltage: 50A
• Operating Temperature Range: -40°C ~ 85°C

Parameter Comparison

Engineering Selection Recommendations

SCHURTER 0034.7210: This part is classified as a parametric equivalent to the SCHURTER 0034.7110, maintaining identical electrical ratings, response characteristics, and mechanical dimensions. Both parts are manufactured by SCHURTER Inc., share the same MSTU 250 series designation, and carry cULus approval. The identical melting I²t value (0.361) ensures matching thermal response behavior. This substitute is suitable for direct replacement in applications where SCHURTER brand continuity or series consistency is preferred.

Littelfuse 37403150410: This part is classified as a similar manufacturer equivalent, meeting all mandatory electrical specifications (315 mA, 250 V AC, Slow Blow response, 50A breaking capacity) and mechanical compatibility requirements (Through Hole, Radial Can Vertical package, -40°C ~ 85°C operating range). The Littelfuse TR5® 374 series provides enhanced approval coverage with both CSA and cULus certifications. The dimensional variation in height (0.315" vs. 0.335") and lower melting I²t value (0.26 vs. 0.361) represent acceptable functional differences within the slow-blow fuse category. This substitute is suitable for applications requiring multi-agency compliance or where Littelfuse supply chain availability is advantageous.

All substitute parts maintain ROHS3 compliance and are classified as Active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 0034.7210 be used as a direct replacement for SCHURTER 0034.7110?

A: Yes. The SCHURTER 0034.7210 is a parametric equivalent with identical current rating (315 mA), voltage rating (250 V AC), response time (Slow Blow), mounting configuration (Through Hole), package type (Radial, Can, Vertical), breaking capacity (50A), operating temperature range (-40°C ~ 85°C), and melting I²t value (0.361). Physical dimensions are identical at 0.335" Dia x 0.335" H. Direct substitution is supported.

Q: What are the key differences between the Littelfuse 37403150410 and the SCHURTER 0034.7110?

A: The Littelfuse 37403150410 maintains all mandatory electrical specifications and mechanical compatibility. Differences include: manufacturer (Littelfuse vs. SCHURTER), series designation (TR5® 374 vs. MSTU 250), approval agencies (CSA and cULus vs. cULus only), height dimension (0.315" vs. 0.335"), melting I²t (0.26 vs. 0.361), and DC cold resistance specification (0.545 Ohms provided). These variations do not affect functional equivalence for 315 mA 250 V AC slow-blow fuse applications.

Q: Are dimensional variations between substitute parts significant?

A: The height variation between SCHURTER 0034.7110 (0.335" H) and Littelfuse 37403150410 (0.315" H) represents a 0.020" difference. Both maintain the same 0.335" diameter and radial through-hole mounting configuration. Verification of PCB layout clearance is recommended for applications with tight vertical spacing constraints, though both parts are classified as Radial, Can, Vertical package types suitable for standard board mount applications.

Q: Do all substitute parts carry the same regulatory approvals?

A: SCHURTER 0034.7110 and 0034.7210 both carry cULus approval. Littelfuse 37403150410 carries both CSA and cULus approvals, providing broader regulatory coverage. All parts are ROHS3 compliant and REACH unaffected. Application-specific regulatory requirements should be verified against the approval agencies listed for each part.

Q: What is the significance of the melting I²t parameter in fuse substitution?

A: Melting I²t defines the thermal energy required to melt the fuse element and is critical for time-current characteristic matching. SCHURTER 0034.7110 and 0034.7210 share identical melting I²t values (0.361), ensuring identical thermal response. Littelfuse 37403150410 has a lower melting I²t (0.26), indicating faster thermal response within the slow-blow category. This difference is acceptable for equivalent slow-blow fuse applications but should be verified against specific circuit protection requirements.

Q: Can these fuses be used in both AC and DC applications?

A: All three parts are rated for 250 V AC/DC operation. The 250 V AC rating applies to alternating current applications, while DC operation is supported at the same voltage rating. Application-specific circuit analysis is required to confirm suitability for DC applications, particularly regarding breaking capacity and thermal characteristics under DC conditions.
