Substitute Part Grouping Explanation

Substitution of the SCHURTER 7010.7050.39 is determined by strict equivalence across the following critical parameters:

• Current Rating: 500 mA (exact match required)
• Voltage Rating - AC: 125 V (exact match required)
• Response Time: Fast Blow (exact match required)
• Mounting Type: Through Hole (exact match required)
• Fuse Type: Board Mount (Cartridge Style Excluded) (exact match required)
• Package / Case: Cartridge, Non-Standard (Axial) (exact match required)
• Breaking Capacity @ Rated Voltage: 300 A (exact match required)
• Operating Temperature Range: -55°C ~ 85°C (exact match required)
• Size / Dimension: 0.093" Dia x 0.315" L (2.36mm x 8.00mm) (exact match required)

Substitute parts must maintain identical electrical and mechanical specifications to ensure direct replacement without circuit redesign or board layout modification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SCHURTER 7010.7050.47

The 7010.7050.47 is the direct equivalent to the obsolete 7010.7050.39. Both parts share identical electrical and mechanical specifications, including current rating, voltage rating, response time, package dimensions, and breaking capacity. The 7010.7050.47 maintains active product status and carries the same approval certifications (CSA, GAM T1, UR). This part is ROHS3 compliant and REACH unaffected, making it suitable for new designs and production environments with environmental compliance requirements.

Secondary Substitute: SCHURTER 7010.7050.13

The 7010.7050.13 provides parametric equivalence with the main part across all critical electrical and mechanical parameters. This part is active and carries CSA and UR approvals. The 7010.7050.13 includes DC voltage rating specification (125 V DC) not stated in the main part, providing expanded application flexibility. Melting I²t value matches the main part at 0.07. ROHS3 compliance and REACH unaffected status are confirmed.

Tertiary Substitute: SCHURTER 7010.6340.13

The 7010.6340.13 maintains electrical and mechanical compatibility with the main part across current rating, voltage rating, response time, mounting type, package configuration, breaking capacity, and operating temperature range. This part is active with ROHS3 compliance and REACH unaffected status. The melting I²t value differs at 0.1 compared to the main part's 0.07, and approval agency information is not specified. This part is suitable for applications where the higher I²t value does not conflict with circuit protection requirements.

Frequently Asked Questions (FAQ)

Q: Can the 7010.7050.47 be used as a direct replacement for the obsolete 7010.7050.39?

A: Yes. The 7010.7050.47 is electrically and mechanically identical to the 7010.7050.39 across all specified parameters, including current rating, voltage rating, response time, package dimensions, and breaking capacity. No circuit modification or board layout change is required.

Q: What is the difference between the 7010.7050.13 and 7010.6340.13 substitutes?

A: Both parts meet the electrical and mechanical requirements of the main part. The 7010.7050.13 has a melting I²t of 0.07, matching the main part exactly. The 7010.6340.13 has a melting I²t of 0.1, which affects the thermal response characteristics. The 7010.7050.13 carries CSA and UR approvals, while the 7010.6340.13 does not specify approval agencies.

Q: Are all substitute parts ROHS3 compliant?

A: The 7010.7050.47, 7010.7050.13, and 7010.6340.13 are all ROHS3 compliant. The main part 7010.7050.39 does not specify RoHS status.

Q: Do the substitute parts maintain the same physical dimensions?

A: Yes. All substitute parts maintain the identical axial cartridge dimensions of 0.093" Dia x 0.315" L (2.36mm x 8.00mm), ensuring compatibility with existing through-hole board layouts.

Q: What is the significance of the melting I²t parameter difference in the 7010.6340.13?

A: The melting I²t value of 0.1 in the 7010.6340.13 differs from the main part's 0.07. This parameter affects the thermal energy required to melt the fuse element. Applications requiring precise thermal response matching should use the 7010.7050.47 or 7010.7050.13, which maintain the 0.07 I²t specification.

Q: Can these fuses be used in both AC and DC applications?

A: The main part 7010.7050.39 specifies 125 V AC rating only. The substitute parts 7010.7050.13 and 7010.6340.13 specify both 125 V AC and 125 V DC ratings, providing expanded application capability. The 7010.7050.47 does not specify DC rating.

Q: What is the operating temperature range for all parts?

A: All parts, including the main part and all substitutes, operate across the temperature range of -55°C to 85°C.
