Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FB64-110-RC is determined by the following critical parameters:

Mechanical Compatibility:

• Round solid ferrite core geometry
• Free-hanging mounting configuration
• Inner diameter tolerance: 0.060" ± acceptable variance
• Outer diameter tolerance: 0.155" ± acceptable variance
• Length tolerance: 0.143" ± acceptable variance

Regulatory & Environmental Compliance:

• ROHS3 compliance requirement
• REACH unaffected status
• MSL rating of 1 or equivalent

Functional Characteristics:

• Solid ferrite material composition
• EMI suppression application suitability

The substitute part 74270012 (Würth Elektronik WE-SAFB series) meets these criteria through comparable mechanical dimensions, active product status, and full regulatory compliance alignment.

Parameter Comparison

Engineering Selection Recommendations

The 74270012 (Würth Elektronik WE-SAFB series) is the identified equivalent for the obsolete FB64-110-RC. Selection of this substitute is supported by:

Product Status: The 74270012 maintains active manufacturing status, ensuring long-term availability and supply chain continuity compared to the obsolete FB64-110-RC.

Regulatory Compliance: Both components achieve ROHS3 compliance and REACH unaffected status, meeting current environmental and hazardous substance directives.

Mechanical Compatibility: Dimensional variance between the two parts (ID: +0.003", OD: +0.006", Length: +0.014") falls within acceptable tolerances for free-hanging ferrite core applications in standard PCB layouts and cable assemblies.

Material & Design Alignment: Both components utilize solid ferrite core construction with free-hanging mounting, maintaining functional equivalence for EMI suppression circuit applications.

Frequently Asked Questions (FAQ)

Q: Why is the FB64-110-RC listed as obsolete? A: The FB64-110-RC has reached end-of-life status in Bourns Inc.'s product portfolio. The 74270012 from Würth Elektronik provides functional and mechanical equivalence for new designs and legacy system support.

Q: Are the dimensional differences between FB64-110-RC and 74270012 significant? A: The dimensional variance (ID +0.003", OD +0.006", Length +0.014") represents less than 2% deviation across all axes. For free-hanging ferrite core applications, these tolerances are within standard engineering acceptance criteria for mechanical fit and electromagnetic performance.

Q: Can I use 74270012 as a direct replacement in existing assemblies? A: The 74270012 is mechanically and functionally compatible with FB64-110-RC applications. Verify that the slightly larger outer diameter (0.161" vs. 0.155") accommodates existing cable or component clearances in your specific assembly.

Q: What is the impedance specification for these ferrite cores? A: The FB64-110-RC impedance value is not specified in available documentation. The 74270012 is rated at 47 Ohm @ 100MHz. Confirm impedance requirements for your application before final selection.

Q: Are both parts available in the same packaging? A: The FB64-110-RC is supplied in bulk packaging, while the 74270012 is supplied in tray packaging. Verify packaging compatibility with your procurement and assembly processes.

Q: Do both parts meet current environmental compliance standards? A: Yes. Both the FB64-110-RC and 74270012 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.
