Engineering Selection Recommendations

SCHURTER 7010.6350.47 is the primary substitute for the obsolete 7010.6350.49. Both parts share identical electrical specifications, mechanical dimensions, and series designation (172321). The 7010.6350.47 maintains active product status and carries GAM T1 approval agency certification. This part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

SCHURTER 7010.7060.13 is a parametric equivalent substitute with identical electrical and mechanical specifications. This part operates under series 172322 and carries dual approval agency certifications (CSA, UR), providing broader regulatory acceptance in certain markets. The 7010.7060.13 is also ROHS3 compliant and REACH unaffected. A minor difference exists in the melting I²t value (0.18 versus 0.28 for the main part), which remains within the fast blow response time classification and does not affect functional substitution.

Both substitute parts are available in active production status with confirmed inventory levels, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 7010.6350.47 be used as a direct replacement for the 7010.6350.49?

A: Yes. The 7010.6350.47 is a direct functional equivalent. Both parts share identical current rating (750 mA), voltage ratings (125 V AC/DC), response time (fast blow), mounting configuration (through-hole), package type (cartridge, non-standard axial), breaking capacity (300 A), and physical dimensions (0.093" Dia x 0.315" L). The primary difference is product status: 7010.6350.47 is active while 7010.6350.49 is obsolete.

Q: What is the difference between the 7010.6350.47 and 7010.7060.13?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The 7010.7060.13 differs in series designation (172322 versus 172321) and approval agency certifications (CSA, UR versus GAM T1). The melting I²t value for 7010.7060.13 is 0.18 compared to 0.28 for 7010.6350.47, but both maintain fast blow classification. Selection between these two depends on specific regulatory requirements and approval agency preferences for your application.

Q: Are there any compatibility concerns when substituting these parts?

A: No compatibility concerns exist for direct substitution. All three parts maintain identical through-hole mounting configuration, cartridge non-standard axial package type, and physical dimensions. Board layout and circuit design require no modification.

Q: What is the significance of the melting I²t difference between 7010.6350.47 and 7010.7060.13?

A: The melting I²t value (0.28 versus 0.18) indicates the thermal energy required to melt the fuse element. Both values correspond to fast blow response time classification. The difference reflects internal design variations between series 172321 and 172322 but does not affect functional performance or substitution suitability for applications designed for 750 mA fast blow fuses.

Q: Which substitute part should be selected for new designs?

A: For new designs, either 7010.6350.47 or 7010.7060.13 is acceptable based on your specific regulatory and approval requirements. The 7010.6350.47 maintains series continuity with the original design. The 7010.7060.13 offers broader regulatory acceptance through dual CSA and UR certifications.

Q: Are both substitute parts ROHS3 compliant?

A: Yes. Both 7010.6350.47 and 7010.7060.13 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.
