Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCHURTER 7010.9965.53 is determined by the following critical parameters:

Primary Matching Criteria:

• Current Rating: 3.15 A (exact match required)
• Fuse Type: Cartridge, Ceramic (exact match required)
• Response Time: Slow Blow (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Series: MSB (same product family)

Secondary Compatibility Factors:

• Package / Case: Cartridge, Non-Standard (physical form factor)
• Manufacturer: SCHURTER Inc. (same manufacturer ensures design compatibility)

The substitute part must maintain identical electrical characteristics (current rating and response time) and physical mounting configuration to ensure functional equivalence in circuit protection applications.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 7010.9965.57 serves as the direct substitute for the obsolete 7010.9965.53. Selection is based on the following engineering factors:

Product Status Alignment: The substitute part is classified as Active, ensuring ongoing availability and manufacturer support, whereas the main part is Obsolete and subject to discontinuation.

Electrical Equivalence: Both parts maintain identical current ratings (3.15 A), fuse type (ceramic cartridge), and response characteristics (slow blow), ensuring equivalent circuit protection performance.

Compliance and Certification: The substitute part carries cURus approval agency certification and is ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements for component procurement and deployment.

Physical Compatibility: Both parts utilize identical mounting type (surface mount) and package format (cartridge, non-standard), ensuring mechanical compatibility with existing PCB designs and assembly processes.

Enhanced Specifications: The substitute part provides complete electrical specifications including voltage ratings (125 V AC/DC), breaking capacity (150 A), and operating temperature range (-55°C ~ 85°C), offering greater design documentation clarity compared to the main part.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 7010.9965.57 be used as a direct replacement for the 7010.9965.53?

A: Yes. Both parts share identical current ratings (3.15 A), fuse type (ceramic cartridge), response time (slow blow), mounting configuration (surface mount), and package format (cartridge, non-standard). The substitute is the active equivalent.

Q: What is the primary reason for substitution?

A: The original part (7010.9965.53) is classified as obsolete. The substitute (7010.9965.57) is an active product with ongoing manufacturer support and availability.

Q: Are there physical dimension differences between the two parts?

A: The substitute part specifies dimensions of 0.079" diameter by 0.276" length (2.00mm x 7.00mm). The main part does not provide dimensional specifications. Both use identical non-standard cartridge packaging, ensuring mechanical compatibility.
