• 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

All identified substitute parts maintain these core electrical and mechanical specifications, ensuring direct functional equivalence in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SCHURTER 7010.7100.47

The 7010.7100.47 is the direct active equivalent to the obsolete 7010.7100.39. Both parts share identical electrical specifications, mechanical dimensions, and thermal characteristics. The 7010.7100.47 maintains active product status and carries ROHS3 compliance and REACH unaffected certification, supporting modern procurement and regulatory requirements.

Secondary Substitutes: SCHURTER 7010.7100.13 and 7010.6390.13

Both 7010.7100.13 and 7010.6390.13 provide parametric equivalence with the main part across all critical electrical and mechanical parameters. These parts are active and ROHS3 compliant. The 7010.7100.13 maintains the same series designation (172322) and approval agencies (CSA, UR) as the main part. The 7010.6390.13 operates under series 172321 with no specified approval agencies but offers higher inventory availability.

Voltage Rating Consideration:

The 7010.7100.13 and 7010.6390.13 specify dual voltage ratings (125 V AC and 125 V DC), whereas the main part 7010.7100.39 specifies only 125 V AC. This expanded voltage specification in substitute parts does not restrict their use in AC-only applications and provides additional operational flexibility.

Melting I²t Variance:

The 7010.6390.13 exhibits a melting I²t value of 1.6 compared to 1.4 in the main part and 7010.7100.47. This represents a minor thermal characteristic difference within the same fuse family and does not preclude substitution for equivalent circuit protection performance.

Frequently Asked Questions (FAQ)

Q: Can the 7010.7100.47 directly replace the obsolete 7010.7100.39?

A: Yes. The 7010.7100.47 maintains identical current rating (2.5 A), voltage rating (125 V AC), fuse type, mounting configuration, package dimensions (0.093" Dia x 0.315" L), response time (fast blow), breaking capacity (300 A), and operating temperature range (-55°C ~ 85°C). The part is active and ROHS3 compliant.

Q: What is the difference between 7010.7100.13 and 7010.6390.13?

A: Both parts meet the electrical and mechanical requirements of the main part. The 7010.7100.13 belongs to series 172322 (matching the main part series) with CSA and UR approvals. The 7010.6390.13 belongs to series 172321 with no specified approval agencies but offers higher inventory availability. The 7010.6390.13 has a melting I²t of 1.6 versus 1.4 in the 7010.7100.13.

Q: Why do some substitute parts specify both 125 V AC and 125 V DC ratings?

A: The 7010.7100.13 and 7010.6390.13 are rated for both AC and DC operation at 125 V. This expanded rating specification does not restrict their use in AC-only circuits and provides design flexibility for applications requiring dual-voltage capability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 7010.7100.47, 7010.7100.13, and 7010.6390.13 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the significance of the melting I²t parameter difference?

A: The melting I²t value characterizes the thermal energy required to melt the fuse element. The 7010.6390.13 has a melting I²t of 1.6 compared to 1.4 in the main part and 7010.7100.47. This minor difference reflects normal variation within the same fuse family and does not affect functional equivalence for circuit protection applications.

Q: Can I use these fuses in both AC and DC circuits?

A: The main part 7010.7100.39 is rated for 125 V AC. The substitute parts 7010.7100.13 and 7010.6390.13 are rated for both 125 V AC and 125 V DC. The 7010.7100.47 is rated for 125 V AC. Verify application voltage requirements before selection.

Q: What approval agencies certify these fuses?

A: The main part carries CSA, GAM T1, and UR approvals. The 7010.7100.47 carries the same approvals. The 7010.7100.13 carries CSA and UR approvals. The 7010.6390.13 has no specified approval agencies listed.
