Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete SCHURTER 7010.9790.59 is determined by the following critical parameters that must remain constant across equivalent components:

Mandatory Matching Parameters:

• Current Rating: 500 mA
• Fuse Type: Cartridge, Ceramic
• Response Time: Fast Blow
• Size / Dimension: 0.079" Dia x 0.276" L (2.00mm x 7.00mm)
• Operating Temperature Range: -55°C ~ 125°C
• Approval Agency: cURus
• Series: 172876
• Manufacturer: SCHURTER Inc.

The substitute part 7010.9790.57 satisfies all mandatory parameters while providing additional specifications including defined voltage ratings (125 V AC / 125 V DC), breaking capacity (300A), and melting I²t (0.046). The primary distinction between the main part and substitute relates to mounting configuration and product status transition from obsolete to active.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 7010.9790.57 serves as the direct substitute for the obsolete 7010.9790.59 based on the following engineering criteria:

Product Status Alignment: The substitute part maintains active product status with SCHURTER Inc., ensuring continued availability and manufacturing support. The obsolete status of the main part creates supply chain risk for ongoing production and field service requirements.

Compliance and Certification: Both components carry cURus approval agency certification, maintaining regulatory compliance across applications. The substitute part provides additional compliance documentation through ROHS3 compliance and REACH unaffected status, supporting modern environmental and regulatory requirements.

Electrical and Mechanical Compatibility: The substitute part preserves all critical electrical parameters including 500 mA current rating, fast-blow response time, and ceramic cartridge construction. Physical dimensions remain identical at 0.079" diameter by 0.276" length, ensuring mechanical fit within existing holder assemblies.

Enhanced Specification Definition: The substitute part provides explicit voltage ratings (125 V AC / 125 V DC), breaking capacity (300A), and melting I²t (0.046) specifications that were not defined in the main part documentation. These parameters establish clear performance boundaries for circuit protection applications.

Frequently Asked Questions (FAQ)

Q: Can SCHURTER 7010.9790.57 directly replace SCHURTER 7010.9790.59 in existing designs?

A: Yes. Both components share identical current ratings (500 mA), fuse type (ceramic cartridge), response time (fast blow), physical dimensions (0.079" Dia x 0.276" L), operating temperature range (-55°C to 125°C), and series designation (172876). The substitute part is electrically and mechanically compatible with applications designed for the main part.

Q: What is the primary difference between these two part numbers?

A: The main distinction is product status. The 7010.9790.59 is classified as obsolete, while the 7010.9790.57 maintains active status. The substitute part also provides defined voltage ratings (125 V AC / 125 V DC) and additional performance specifications (300A breaking capacity, 0.046 melting I²t) not documented in the main part.

Q: Are there mounting configuration differences between these parts?

A: The main part specifies surface mount mounting type, while the substitute part requires a holder. Both components use identical non-standard cartridge form factors. System integration must account for holder requirements when implementing the substitute part.

Q: Do both parts meet current regulatory requirements?

A: The substitute part 7010.9790.57 provides explicit ROHS3 compliance and REACH unaffected status documentation. Both components carry cURus approval certification. For applications requiring specific environmental compliance documentation, the substitute part offers more comprehensive regulatory alignment.

Q: What is the inventory status for these components?

A: The main part (7010.9790.59) shows 1006 pieces in stock as new original inventory. The substitute part (7010.9790.57) shows 4099 pieces in stock as new original inventory in tape and reel packaging, providing superior supply availability.

Q: Are the electrical performance characteristics identical?

A: Both components share identical current ratings, response times, and operating temperature ranges. The substitute part provides additional electrical specifications including 300A breaking capacity and 0.046 melting I²t, which were not specified for the main part. These additional parameters define performance boundaries within the same functional class.
