FB73-422-RC Equivalent & Substitute Parts

Part Overview

The FB73-422-RC is a solid free hanging ferrite core manufactured by Bourns Inc., designed for electromagnetic interference (EMI) suppression and signal integrity applications. With an inner diameter of 0.070" (1.77mm), outer diameter of 0.215" (5.46mm), and length of 0.462" (11.73mm), this component is classified as obsolete. Due to its discontinued status, identifying equivalent substitute parts is essential for ongoing production support and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FB73-422-RC are identified based on the following critical parameters that determine functional equivalence:

• Type & Design: Round solid ferrite core geometry
• Mounting Configuration: Free hanging installation method
• Dimensional Compatibility: Inner diameter, outer diameter, and length tolerances
• Material Classification: Ferrite core material suitable for EMI suppression
• Regulatory Compliance: RoHS3 and REACH compliance status
• Availability & Status: Active product status with current manufacturing support

The substitute part 74270015 from Würth Elektronik meets these core substitution criteria while maintaining mechanical and regulatory compatibility.

Parameter Comparison

Engineering Selection Recommendations

The FB73-422-RC is obsolete and no longer manufactured by Bourns Inc. The Würth Elektronik 74270015 is an active substitute part that maintains compliance with ROHS3 and REACH regulations. Both components are solid round ferrite cores with free hanging mounting configurations, ensuring mechanical compatibility in existing designs.

The 74270015 features specified impedance characteristics (95Ohm @ 100MHz) and is actively produced with current inventory availability. Selection of this substitute part is supported by regulatory compliance alignment and active manufacturing status, providing long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the 74270015 directly replace the FB73-422-RC in existing assemblies?

A: Both parts share identical mounting type (free hanging) and core design (solid round ferrite). However, dimensional variations exist: the 74270015 has a slightly larger inner diameter (0.079" vs 0.070") and smaller outer diameter (0.157" vs 0.215"). Physical fit must be verified against the specific application's mechanical constraints before implementation.

Q: What are the key differences between these ferrite cores?

A: The primary differences are dimensional (inner/outer diameter and length) and material composition (73 vs 4W620). The 74270015 provides specified impedance data (95Ohm @ 100MHz), whereas the FB73-422-RC does not include impedance specifications in the available documentation.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the FB73-422-RC and 74270015 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the packaging format for the substitute part?

A: The 74270015 is supplied in bag packaging. Confirm packaging requirements align with your assembly and inventory management processes.

Q: Why is the FB73-422-RC obsolete?

A: The FB73-422-RC has been discontinued by Bourns Inc. and is no longer in active production. The 74270015 from Würth Elektronik represents an active alternative with current manufacturing support and inventory availability.
