Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 7010.7110.39 are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Primary Matching Parameters:

• Current Rating: 3 A (exact match required)
• Voltage Rating (AC): 125 V (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Cartridge, Non-Standard (Axial) (exact match required)
• Response Time: Fast Blow (exact match required)
• Physical Dimensions: 0.093" Dia x 0.315" L (exact match required)
• Breaking Capacity @ Rated Voltage: 300 A (exact match required)

Secondary Considerations:

• Product Status: Active status preferred for ongoing availability
• Compliance Certifications: CSA, UR, and additional certifications enhance suitability
• Melting I²t: Values within acceptable range for thermal characteristics

Two substitute parts meet these criteria and are classified as direct equivalents.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SCHURTER 7010.7110.47

The 7010.7110.47 is the preferred substitute for the obsolete 7010.7110.39. This part maintains identical electrical and mechanical specifications across all critical parameters: 3A current rating, 125VAC voltage rating, fast-blow response, 300A breaking capacity, and matching physical dimensions. The 7010.7110.47 holds active product status, ensuring long-term availability and supply chain continuity. This part carries expanded compliance certifications including CE, CSA, GAMT1, and UR approvals, and is ROHS3 compliant with REACH unaffected status. Current inventory of 1134 pieces supports immediate procurement requirements.

Secondary Substitute: SCHURTER 7010.6400.13

The 7010.6400.13 provides an alternative equivalent with identical electrical and mechanical core specifications. This part differs in two aspects: it specifies dual voltage rating capability (125V AC and 125V DC) and exhibits a slightly elevated melting I²t value of 2.4 compared to the main part's value of 2. The 7010.6400.13 maintains active product status, ROHS3 compliance, and REACH unaffected status. However, approval agency certifications are not specified for this part. Packaging is supplied in bulk format. Current inventory of 637 pieces is available.

Selection Basis:

For direct replacement applications requiring AC-only operation with existing compliance documentation, the 7010.7110.47 is the optimal choice due to matching certifications and active status. For applications where dual AC/DC voltage capability provides operational flexibility, the 7010.6400.13 serves as a functional equivalent, provided that the elevated melting I²t characteristic is acceptable within the circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can the 7010.7110.47 be used as a direct replacement for the 7010.7110.39?

A: Yes. The 7010.7110.47 matches all critical electrical and mechanical parameters of the 7010.7110.39, including current rating (3A), voltage rating (125VAC), response time (fast-blow), breaking capacity (300A), and physical dimensions (0.093" Dia x 0.315" L). The 7010.7110.47 is active and carries expanded compliance certifications.

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

A: Both parts share identical current rating, AC voltage rating, mounting type, package type, response time, breaking capacity, and physical dimensions. The 7010.6400.13 adds DC voltage rating capability (125V DC) and exhibits a melting I²t value of 2.4 versus 2.0 for the 7010.7110.47. The 7010.6400.13 does not specify approval agency certifications.

Q: Are these parts physically interchangeable on the PCB?

A: Yes. All three parts (7010.7110.39, 7010.7110.47, and 7010.6400.13) share identical physical dimensions of 0.093" Dia x 0.315" L (2.36mm x 8.00mm) and use the same through-hole mounting configuration. No PCB layout modifications are required.

Q: Does the 7010.6400.13 dual voltage rating affect AC-only applications?

A: No. The 7010.6400.13 is rated for both 125V AC and 125V DC operation. In AC-only applications, the part operates within its AC voltage specification of 125V. The additional DC rating does not degrade AC performance.

Q: What is the significance of the melting I²t difference between parts?

A: The melting I²t value characterizes the thermal energy required to melt the fuse element. The 7010.7110.47 has a melting I²t of 2, while the 7010.6400.13 has a value of 2.4. This difference reflects slightly different thermal response characteristics. Selection between these parts depends on circuit-specific thermal requirements and existing design validation.

Q: Are all substitute parts ROHS3 compliant?

A: The 7010.7110.47 and 7010.6400.13 are both ROHS3 compliant. The original 7010.7110.39 does not specify RoHS status due to its obsolete classification.

Q: What compliance certifications apply to each part?

A: The 7010.7110.39 carries CSA, GAM T1, and UR approvals. The 7010.7110.47 carries CE, CSA, GAMT1, and UR approvals. The 7010.6400.13 does not specify approval agency certifications in the available documentation.

Q: Is packaging format a consideration for substitution?

A: Packaging format does not affect electrical or mechanical compatibility. The 7010.7110.39 and 7010.7110.47 packaging is not specified. The 7010.6400.13 is supplied in bulk packaging. Selection of packaging format depends on procurement and inventory management requirements rather than functional substitution criteria.
