SCHURTER 7010.6410.37 Board Mount Axial Fuse Equivalent & Substitute Parts

Part Overview

The SCHURTER 7010.6410.37 is a 4 A, 125 V AC/DC board mount axial fuse with fast blow response characteristics. This component is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design support and procurement continuity. The fuse is designed for through-hole mounting applications requiring cartridge-style, non-standard axial configuration with a breaking capacity of 300 A at rated voltage.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCHURTER 7010.6410.37 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 4 A
• Voltage Rating (AC): 125 V
• Voltage Rating (DC): 125 V
• Response Time: Fast Blow
• Mounting Type: Through Hole
• Package / Case: Cartridge, Non-Standard (Axial)
• Size / Dimension: 0.093" Dia x 0.315" L (2.36mm x 8.00mm)
• Breaking Capacity @ Rated Voltage: 300 A
• Operating Temperature Range: -55°C ~ 85°C

Substitute parts are grouped into two categories: direct form-fit-function equivalents and parametric equivalents. Direct equivalents maintain identical electrical and mechanical specifications with active product status. Parametric equivalents satisfy all critical electrical and mechanical parameters while differing in series designation, packaging configuration, or approval agency certifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SCHURTER 7010.6410.47

The 7010.6410.47 is the direct form-fit-function equivalent to the obsolete 7010.6410.37. Both components share identical electrical ratings (4 A, 125 V AC/DC), response characteristics (fast blow), mechanical dimensions (0.093" Dia x 0.315" L), and breaking capacity (300 A). The 7010.6410.47 maintains the same series designation (172321) and approval agency certification (GAM T1). This part is currently in active production status with 1043 units in stock and carries ROHS3 compliance certification.

Secondary Substitute: SCHURTER 7010.7120.13

The 7010.7120.13 is a parametric equivalent satisfying all critical electrical and mechanical specifications. This part differs in series designation (172322), melting I²t value (4 versus 5.7), and approval agency certifications (CSA, UR versus GAM T1). The 7010.7120.13 is supplied in bulk packaging configuration and is currently in active production status with 985 units in stock. ROHS3 compliance and REACH unaffected status are confirmed.

Selection between the primary and secondary substitute depends on approval agency requirements and melting I²t specifications for the target application. Both substitutes are active products with confirmed inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the 7010.6410.47 be used as a direct replacement for the obsolete 7010.6410.37?

A: Yes. The 7010.6410.47 is a direct form-fit-function equivalent. All electrical parameters (4 A, 125 V AC/DC, fast blow response), mechanical dimensions (0.093" Dia x 0.315" L), mounting configuration (through hole, axial cartridge), and performance specifications (300 A breaking capacity, -55°C to 85°C operating range) are identical. Both components carry GAM T1 approval agency certification.

Q: What is the difference between the 7010.6410.47 and 7010.7120.13 substitutes?

A: The primary differences are series designation (172321 versus 172322), melting I²t value (5.7 versus 4), approval agency certifications (GAM T1 versus CSA, UR), and packaging configuration (standard versus bulk). All other electrical and mechanical parameters are identical. Selection depends on application-specific approval requirements and thermal characteristics.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both substitute parts, 7010.6410.47 and 7010.7120.13, are ROHS3 compliant. The original obsolete part 7010.6410.37 does not specify RoHS status.

Q: What is the significance of the melting I²t difference between substitutes?

A: The melting I²t value (5.7 for 7010.6410.47 versus 4 for 7010.7120.13) represents the thermal energy required to melt the fuse element. Both values are provided in the component specifications. Application requirements determine which value is appropriate for circuit protection design.

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

A: Yes. Both substitute parts are rated for 125 V AC and 125 V DC operation, identical to the original part. The 4 A current rating applies to both AC and DC applications within the specified voltage range.

Q: What is the inventory status of the substitute parts?

A: The 7010.6410.47 has 1043 units in stock. The 7010.7120.13 has 985 units in stock. Both are classified as new original components in active production.
