SCHURTER 0034.7107 Board Mount Fuse - Equivalent & Substitute Parts

Part Overview

The SCHURTER 0034.7107 is a 160 mA, 250 V AC/DC board mount fuse with slow blow response characteristics, designed for through-hole radial mounting in vertical orientation. This fuse is classified as active product status with full cULus approval and ROHS3 compliance. Alternative equivalent parts become necessary when primary inventory is unavailable, when sourcing from multiple suppliers is required for supply chain resilience, or when design flexibility across approved manufacturers is needed while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 0034.7107 is determined by strict equivalence across the following critical parameters: current rating (160 mA), voltage rating (250 V AC), response time (slow blow), mounting type (through hole), fuse type (board mount, cartridge style excluded), package configuration (radial, can, vertical), breaking capacity (50 A), and operating temperature range (-40°C ~ 85°C).

The substitute parts identified meet these core electrical and mechanical requirements. SCHURTER 0034.7207 is a parametric equivalent from the same manufacturer and series (MSTU 250), offering identical specifications across all critical parameters. Littelfuse 37401600410 from the TR5® 374 series is classified as a similar manufacturer part, meeting all primary electrical and mechanical criteria while originating from a different manufacturer and product line.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status with full regulatory compliance. SCHURTER 0034.7207 is the primary parametric equivalent, sharing identical manufacturer lineage, series designation (MSTU 250), and all electrical and mechanical specifications with the main part. This part is recommended when maintaining single-manufacturer sourcing is preferred.

Littelfuse 37401600410 qualifies as a functional substitute based on matching all critical electrical parameters and core mechanical requirements. This part carries dual approval (CSA and cULus) compared to the single cULus approval of the main part, providing additional regulatory coverage. The height dimension differs by 0.020" (0.50mm), which must be evaluated against specific PCB layout constraints. The melting I²t value of 0.058 differs from the main part specification of 0.0692, representing a thermal characteristic variation that should be assessed within the application's thermal management context.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 0034.7207 be used as a direct replacement for SCHURTER 0034.7107?

A: Yes. Both parts are from SCHURTER Inc., share the MSTU 250 series designation, and possess identical electrical ratings (160 mA, 250 V AC), response time (slow blow), mounting configuration (through hole radial), and physical dimensions (0.335" Dia x 0.335" H). No design modifications are required.

Q: What is the key difference between the Littelfuse 37401600410 and the main part?

A: The Littelfuse part maintains all critical electrical specifications but differs in two areas: physical height (0.315" versus 0.335") and melting I²t value (0.058 versus 0.0692). Both differences must be evaluated against specific application requirements before substitution.

Q: Are all three parts ROHS3 compliant?

A: Yes. SCHURTER 0034.7107, SCHURTER 0034.7207, and Littelfuse 37401600410 are all ROHS3 compliant.

Q: What approval agencies certify these fuses?

A: SCHURTER 0034.7107 and 0034.7207 carry cULus approval. Littelfuse 37401600410 carries both CSA and cULus approvals.

Q: Can the Littelfuse part be used in applications with strict height constraints?

A: The Littelfuse 37401600410 has a maximum height of 0.315" compared to 0.335" for the SCHURTER parts. Applications with tight vertical clearance may benefit from this reduced height, but PCB layout compatibility must be confirmed before substitution.

Q: Are the melting I²t differences significant for substitution?

A: The melting I²t values (0.0692 for SCHURTER parts, 0.058 for Littelfuse) represent thermal response characteristics. The application's thermal management design and fault current profiles must be evaluated to determine if this variation is acceptable.
