FB20010-3B Ferrite Bead Equivalent & Substitute Parts

Part Overview

The FB20010-3B is a 780 Ohm axial ferrite bead manufactured by Bourns Inc., designed for single-line EMI suppression applications with a maximum current rating of 5A. This component is classified as obsolete, which necessitates identification of active equivalent parts for ongoing procurement and design continuity. The ferrite bead operates at 100 MHz impedance specification and utilizes through-hole axial packaging with standard dimensions of 0.236" diameter by 0.394" length (5.99mm x 10.01mm).

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FB20010-3B is determined by equivalence across the following critical parameters:

• Impedance specification: 780 Ohms @ 100 MHz
• Current rating: 5A maximum
• Number of lines: Single-line configuration
• Physical form factor: Axial through-hole package
• Mechanical dimensions: 0.236" diameter x 0.394" length
• Manufacturer series: FB (Bourns ferrite bead line)

The FB20010-3B-RC meets all electrical and mechanical requirements for direct substitution. Both parts share identical impedance, current capacity, line configuration, and physical dimensions. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The FB20010-3B-RC is the direct functional equivalent for the obsolete FB20010-3B. Both parts deliver identical electrical performance across all specified parameters: 780 Ohm impedance at 100 MHz, 5A current capacity, and single-line configuration. Physical compatibility is confirmed through matching axial through-hole form factor and dimensions.

The FB20010-3B-RC offers additional advantages for new designs and ongoing procurement: active product status ensures continued availability, and ROHS3 compliance satisfies modern regulatory requirements. The original FB20010-3B is RoHS non-compliant, making the substitute the appropriate choice for applications subject to RoHS directives.

Packaging differs between the two parts: the original uses tape and reel format, while the substitute is supplied in bulk. This distinction affects procurement logistics but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can FB20010-3B-RC replace FB20010-3B in existing designs?

A: Yes. The FB20010-3B-RC is electrically and mechanically equivalent. Both parts share identical impedance (780 Ohms @ 100 MHz), current rating (5A), line configuration (single-line), and physical dimensions (0.236" Dia x 0.394" L). Through-hole axial mounting is identical between both parts.

Q: What is the primary reason to transition from FB20010-3B to FB20010-3B-RC?

A: The FB20010-3B is classified as obsolete, creating procurement risk. The FB20010-3B-RC is an active product with confirmed ongoing availability. Additionally, the substitute meets ROHS3 compliance, whereas the original does not.

Q: Are there differences in electrical performance between these parts?

A: No. Both parts deliver 780 Ohms impedance at 100 MHz and support 5A maximum current. Electrical characteristics are identical.

Q: Does packaging format affect component selection?

A: Packaging format (tape and reel versus bulk) affects procurement and handling logistics but does not impact electrical or mechanical performance. Component selection should be based on electrical specifications and physical form factor compatibility.

Q: Is the FB20010-3B-RC suitable for new product designs?

A: Yes. The FB20010-3B-RC is an active product with ROHS3 compliance, making it appropriate for new designs and applications subject to RoHS directives.
