SCHURTER 7010.7040.39 Board Mount Fuse Equivalent & Substitute Parts

Part Overview

The SCHURTER 7010.7040.39 is a 375 mA, 125 V AC board mount fuse with axial cartridge configuration, rated for fast-blow response. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design support and procurement continuity. The fuse is designed for through-hole mounting applications requiring cartridge-style protection in non-standard axial form factor.

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 7010.7040.39 is determined by strict equivalence across the following parameters: current rating (375 mA), AC voltage rating (125 V), response time classification (fast blow), mounting configuration (through-hole), package geometry (cartridge, non-standard axial), breaking capacity (300 A), melting I²t value (0.019), physical dimensions (0.093" Dia x 0.315" L), and operating temperature range (-55°C to 85°C).

Identified substitute parts maintain all specified electrical and mechanical characteristics. Substitutes are grouped based on product status (active versus obsolete) and compliance certifications. The primary distinction between substitute candidates relates to voltage rating scope (AC-only versus AC/DC dual rating) and regulatory approval agency coverage.

Engineering Selection Recommendations

SCHURTER 7010.7040.47 is the primary substitute for the obsolete 7010.7040.39. This part maintains identical electrical specifications, physical dimensions, and approval agency certifications (CSA, GAM T1, UR). The 7010.7040.47 carries active product status and ROHS3 compliance, supporting long-term design continuity and regulatory alignment.

SCHURTER 7010.7040.13 serves as a parametric equivalent with extended voltage rating capability (125 V AC/DC dual rating). This part is active and ROHS3 compliant. The 7010.7040.13 carries CSA and UR approvals; however, GAM T1 certification is not specified. Selection of this part is appropriate for applications requiring DC voltage protection in addition to AC protection, provided that GAM T1 certification is not a mandatory design requirement.

Both substitute parts are available in active production status, ensuring procurement reliability and supply chain continuity compared to the obsolete main part number.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 7010.7040.47 be used as a direct replacement for 7010.7040.39?

A: Yes. The 7010.7040.47 maintains identical current rating (375 mA), AC voltage rating (125 V), response time (fast blow), breaking capacity (300 A), melting I²t (0.019), physical dimensions (0.093" Dia x 0.315" L), operating temperature range (-55°C to 85°C), and approval agency certifications (CSA, GAM T1, UR). The primary distinction is product status: 7010.7040.47 is active while 7010.7040.39 is obsolete.

Q: What is the difference between 7010.7040.47 and 7010.7040.13?

A: Both parts are parametrically equivalent across all electrical and mechanical specifications. The 7010.7040.13 provides extended voltage rating (125 V AC/DC) compared to 7010.7040.47 (125 V AC only). The 7010.7040.13 carries CSA and UR approvals; GAM T1 certification is not specified for this part. Selection depends on whether DC voltage protection is required and whether GAM T1 certification is mandatory for the application.

Q: Are the physical dimensions identical across all three part numbers?

A: Yes. All three parts share identical cartridge dimensions: 0.093" diameter by 0.315" length (2.36mm x 8.00mm). Through-hole mounting compatibility is maintained across all variants.

Q: What compliance certifications apply to each part?

A: The 7010.7040.39 (obsolete) and 7010.7040.47 (active) both carry CSA, GAM T1, and UR approvals. The 7010.7040.13 (active) carries CSA and UR approvals only; GAM T1 certification is not listed. Verify certification requirements against your design specifications before part selection.

Q: Are both substitute parts ROHS3 compliant?

A: Yes. Both SCHURTER 7010.7040.47 and 7010.7040.13 are ROHS3 compliant. The obsolete 7010.7040.39 does not specify RoHS status.

Q: What is the melting I²t value, and why is it important?

A: The melting I²t value for all three parts is 0.019. This parameter defines the thermal energy required to melt the fuse element and is critical for circuit protection coordination. Identical I²t values ensure equivalent protection characteristics across all substitute parts.
