Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 7010.7040.49 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current Rating: 375 mA
• Voltage Rating (AC): 125 V
• Response Time: Fast Blow
• Mounting Type: Through Hole
• Package Type: Cartridge, Non-Standard (Axial)
• Physical Dimensions: 0.093" Dia x 0.315" L (2.36mm x 8.00mm)
• Breaking Capacity: 300 A @ Rated Voltage
• Melting I²t: 0.019

Acceptable Variations:

• Product Status: Active substitutes preferred over obsolete
• Voltage Rating (DC): Additional DC rating capability does not disqualify substitution
• Packaging Format: Bulk or standard packaging acceptable
• RoHS/REACH Compliance: Enhanced compliance status acceptable

All identified substitute parts maintain identical electrical and mechanical specifications to the main part, ensuring direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SCHURTER 7010.7040.47

The 7010.7040.47 is the direct equivalent to the obsolete 7010.7040.49. Both parts share identical electrical ratings, mechanical dimensions, and response characteristics. The 7010.7040.47 maintains active product status with ROHS3 compliance and REACH unaffected designation, providing regulatory alignment for current manufacturing environments. Approval agencies include CSA, GAM T1, and UR certifications.

Secondary Substitute: SCHURTER 7010.7040.13

The 7010.7040.13 provides parametric equivalence with the addition of 125 V DC voltage rating capability. This part is active and ROHS3 compliant with REACH unaffected status. The 7010.7040.13 carries CSA and UR approvals. The absence of GAM T1 certification should be evaluated against specific application requirements. The DC voltage rating extension does not compromise AC circuit compatibility.

Both substitute parts are manufactured by SCHURTER Inc. within the 172322 series and maintain identical current, voltage (AC), response time, mounting configuration, physical dimensions, breaking capacity, and thermal characteristics as the main part.

Frequently Asked Questions (FAQ)

Q: Can the 7010.7040.47 be used as a direct replacement for the 7010.7040.49?

A: Yes. The 7010.7040.47 is electrically and mechanically identical to the 7010.7040.49. Both parts have 375 mA current rating, 125 V AC voltage rating, fast-blow response, identical physical dimensions (0.093" Dia x 0.315" L), and 300 A breaking capacity. The primary difference is product status: 7010.7040.47 is active while 7010.7040.49 is obsolete.

Q: What is the difference between 7010.7040.47 and 7010.7040.13?

A: The 7010.7040.13 includes an additional 125 V DC voltage rating, whereas the 7010.7040.47 specifies only 125 V AC. All other electrical and mechanical parameters are identical. The 7010.7040.13 also differs in approval agencies (CSA, UR versus CSA, GAM T1, UR for the 7010.7040.47).

Q: Are the physical dimensions identical across all three parts?

A: Yes. All three parts—7010.7040.49, 7010.7040.47, and 7010.7040.13—share identical dimensions of 0.093" Dia x 0.315" L (2.36mm x 8.00mm). They are all cartridge, non-standard (axial) configuration fuses suitable for through-hole board mounting.

Q: Does the 7010.7040.13 DC voltage rating affect AC circuit operation?

A: No. The 7010.7040.13 maintains full 125 V AC rating and fast-blow response characteristics. The additional DC rating does not alter AC performance and does not disqualify its use in AC-only applications.

Q: What are the approval agency differences between substitute parts?

A: The 7010.7040.49 and 7010.7040.47 carry CSA, GAM T1, and UR approvals. The 7010.7040.13 carries CSA and UR approvals. Applications requiring GAM T1 certification should specify the 7010.7040.47.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both 7010.7040.47 and 7010.7040.13 are ROHS3 compliant and REACH unaffected, meeting current environmental regulatory requirements.

Q: What is the melting I²t value, and is it consistent across all parts?

A: The melting I²t value is 0.019 for all three parts. This parameter defines the thermal energy required to melt the fuse element and is identical across the main part and both substitutes.

Q: Can these fuses be used in DC circuits?

A: The 7010.7040.49 and 7010.7040.47 are rated for 125 V AC. The 7010.7040.13 is rated for both 125 V AC and 125 V DC. DC application suitability depends on the specific part selected.
