Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCHURTER 7010.7110.49 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Current Rating: 3 A (exact match required)
• Voltage Rating (AC): 125 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Breaking Capacity @ Rated Voltage: 300A (exact match required)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Size / Dimension: 0.093" Dia x 0.315" L (2.36mm x 8.00mm) (exact match required)

Environmental Parameters:

• Operating Temperature Range: -55°C ~ 85°C (exact match required)

Substitute parts must satisfy all parameters listed above. Variations in series designation, product status, or compliance certifications do not affect substitution eligibility when electrical and mechanical specifications remain identical.

Engineering Selection Recommendations

Primary Substitute: SCHURTER 7010.7110.47

The 7010.7110.47 is the direct functional equivalent to the obsolete 7010.7110.49. Both components share identical electrical ratings (3A, 125VAC), mechanical dimensions (0.093" Dia x 0.315" L), and response characteristics (Fast Blow). The 7010.7110.47 maintains active product status with expanded approval certifications (CE, CSA, GAMT1, UR) compared to the main part. This substitute is suitable for direct replacement in existing designs without circuit modification.

Secondary Substitute: SCHURTER 7010.6400.13

The 7010.6400.13 provides parametric equivalence with additional DC voltage rating capability (125V DC). This part maintains all critical AC specifications (3A, 125VAC, Fast Blow, 300A breaking capacity) and identical physical dimensions. The melting I²t value differs slightly (2.4 versus 2), representing a minor thermal characteristic variation. The 7010.6400.13 is available in bulk packaging and carries ROHS3 compliance. This substitute is applicable when DC voltage rating compatibility is required or when bulk packaging aligns with procurement requirements.

Compliance Considerations:

The 7010.7110.47 is recommended for applications requiring CE certification compliance. The 7010.6400.13 lacks specified approval agency certifications and should be evaluated against specific regulatory requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can the 7010.7110.47 be used as a direct replacement for the 7010.7110.49?

A: Yes. The 7010.7110.47 maintains identical electrical specifications (3A, 125VAC), response time (Fast Blow), breaking capacity (300A), and physical dimensions (0.093" Dia x 0.315" L). Both components are through-hole mounted axial cartridge fuses with identical operating temperature ranges (-55°C ~ 85°C). Direct substitution is supported without circuit redesign.

Q: What is the difference between the 7010.7110.47 and 7010.6400.13?

A: The primary difference is DC voltage rating. The 7010.6400.13 is rated for 125V DC in addition to 125V AC, while the 7010.7110.47 is AC-rated only. The melting I²t value also differs (2.4 for 7010.6400.13 versus 2 for 7010.7110.47). All other electrical and mechanical parameters remain equivalent. The 7010.6400.13 is available in bulk packaging.

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

A: Yes. All three parts (7010.7110.49, 7010.7110.47, and 7010.6400.13) share identical dimensions of 0.093" Dia x 0.315" L (2.36mm x 8.00mm). PCB footprint compatibility is maintained across all substitutes.

Q: Which substitute should be selected for new designs?

A: The 7010.7110.47 is recommended for new designs requiring AC-only operation with CE certification compliance. The 7010.6400.13 is suitable when DC voltage capability is required or when bulk packaging is preferred. Both parts are active products with confirmed availability.

Q: Does the melting I²t difference between 7010.7110.47 and 7010.6400.13 affect circuit protection?

A: The melting I²t value (2 versus 2.4) represents a thermal characteristic parameter. Both parts maintain identical current rating (3A), voltage rating (125VAC), and response time (Fast Blow). Circuit protection behavior under rated conditions remains equivalent. Application-specific thermal analysis may be required for specialized high-energy transient environments.

Q: What certifications are available for each substitute?

A: The 7010.7110.49 carries CSA, GAM T1, and UR approvals. The 7010.7110.47 includes CE, CSA, GAMT1, and UR certifications. The 7010.6400.13 does not specify approval agency certifications. Regulatory requirements should be verified against specific application standards before final selection.

Q: Is RoHS compliance required for substitution?

A: The 7010.7110.49 does not specify RoHS status. Both active substitutes (7010.7110.47 and 7010.6400.13) are ROHS3 compliant. Applications requiring RoHS compliance should select either active substitute.
