Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SCHURTER 7010.6440.49 are classified based on strict electrical and mechanical parameter alignment. All substitute candidates maintain the following critical specifications:

Electrical Parameters (Non-Negotiable):

• Current Rating: 7 A
• Voltage Rating: 125 V AC / 125 V DC
• Response Time: Fast Blow
• Breaking Capacity: 300 A at rated voltage

Mechanical Parameters (Non-Negotiable):

• Mounting Type: Through Hole
• Package Type: Cartridge, Non-Standard (Axial)
• Physical Dimensions: 0.093" Dia x 0.315" L (2.36mm x 8.00mm)
• Operating Temperature: -55°C ~ 85°C

Substitutes are grouped into two categories: direct replacements with identical melting I²t characteristics, and parametric equivalents with minor variations in thermal characteristics that do not affect circuit protection function.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SCHURTER 7010.6440.47

The 7010.6440.47 is the recommended direct replacement for the obsolete 7010.6440.49. Both parts share identical electrical and mechanical specifications, including current rating, voltage ratings, response time, breaking capacity, and physical dimensions. The 7010.6440.47 maintains active product status and is ROHS3 compliant, supporting modern supply chain requirements. Inventory availability is higher (1,072 units) compared to the main part (702 units), ensuring supply continuity.

Secondary Substitute: SCHURTER 7010.7140.13

The 7010.7140.13 is a parametric equivalent suitable for applications where thermal characteristics are not critical design constraints. This part maintains all electrical and mechanical parameters identical to the main part, with the exception of melting I²t (13 versus 15). The lower I²t value indicates faster thermal response, which may be advantageous in sensitive circuit protection applications. This part carries active product status, ROHS3 compliance, and broader approval agency certifications (CSA, UR), providing enhanced regulatory coverage. Bulk packaging is available.

Tertiary Substitute: SCHURTER 7010.6440.13

The 7010.6440.13 is a parametric equivalent within the same series (172321) as the main part. This part maintains identical electrical and mechanical specifications with matching melting I²t (15). Product status and compliance information are not specified in available documentation.

Frequently Asked Questions (FAQ)

Q: Can the 7010.6440.47 be used as a direct replacement for the 7010.6440.49?

A: Yes. The 7010.6440.47 is electrically and mechanically identical to the 7010.6440.49. Both parts have 7 A current rating, 125 V AC/DC voltage rating, fast-blow response, 300 A breaking capacity, and identical physical dimensions (0.093" Dia x 0.315" L). The 7010.6440.47 is active and ROHS3 compliant, making it the preferred replacement for obsolete inventory.

Q: What is the difference between the 7010.6440.49 and 7010.7140.13?

A: The primary difference is melting I²t: the 7010.6440.49 has I²t of 15, while the 7010.7140.13 has I²t of 13. All other electrical and mechanical parameters are identical. The lower I²t of the 7010.7140.13 results in faster thermal response. Additionally, the 7010.7140.13 carries CSA and UR approvals versus GAM T1 for the main part, and is available in bulk packaging.

Q: Are all substitute parts through-hole mounted?

A: Yes. All substitute parts listed maintain through-hole mounting type with axial cartridge package configuration. Physical dimensions are identical across all parts (0.093" Dia x 0.315" L).

Q: What is the operating temperature range for these fuses?

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

Q: Does the 7010.7140.13 come in different packaging options?

A: Yes. The 7010.7140.13 is available in bulk packaging, whereas the 7010.6440.47 and 7010.6440.13 are supplied in standard packaging configurations.

Q: Are the substitute parts RoHS compliant?
