KEMET B-02-RTF Ferrite Bead Equivalent & Substitute Parts

Part Overview

The KEMET B-02-RTF is an active ferrite bead component designed for signal line filtering applications. This axial, split radial bend ferrite bead operates at 4 Ohms impedance at 1 MHz and supports a maximum current rating of 5A. The component is packaged in Tape & Reel (TR) format for automated assembly processes. Substitute parts are identified based on identical electrical performance and mechanical compatibility while accommodating different packaging formats for supply chain flexibility.

Substitute Part Grouping Explanation

Substitute parts for the B-02-RTF are determined by strict equivalence across the following critical parameters:

• Impedance @ Frequency: 4 Ohms @ 1 MHz
• Current Rating (Max): 5A
• Filter Type: Signal Line
• Number of Lines: 1
• Operating Temperature Range: -20°C ~ 70°C
• Package / Case: Axial, Split Radial Bend
• Mounting Type: Through Hole
• Size / Dimension: 0.165" Dia x 0.236" L (4.20mm x 6.00mm)
• Series: BEAD L
• RoHS Status: ROHS3 Compliant

The primary difference between the main part and its substitute is the packaging format. The B-02-RTF is supplied in Tape & Reel (TR) format, while the B-02-RT substitute is supplied in Cut Tape (CT) format. Both formats contain electrically and mechanically identical components and differ only in supply presentation and handling method.

Parameter Comparison

Engineering Selection Recommendations

Both the B-02-RTF and B-02-RT are active products with identical ROHS3 compliance and REACH status. Selection between these parts is determined by packaging requirements and supply chain logistics rather than electrical or mechanical performance.

The B-02-RTF in Tape & Reel format is suitable for high-volume automated assembly operations where components are fed directly into pick-and-place equipment. The B-02-RT in Cut Tape format is appropriate for lower-volume applications, manual assembly processes, or situations where individual component access is required. Both parts deliver equivalent electrical performance and thermal characteristics across the specified operating temperature range.

Frequently Asked Questions (FAQ)

Q: Are the B-02-RTF and B-02-RT electrically identical?

A: Yes. Both parts are from the KEMET BEAD L series and deliver 4 Ohms impedance at 1 MHz with a 5A maximum current rating. Electrical performance, impedance characteristics, and thermal operating range are identical.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly. Cut Tape packaging supplies components on tape segments, typically used for manual assembly or lower-volume applications. The components themselves are identical.

Q: Can I use B-02-RT as a direct replacement for B-02-RTF in my design?

A: Yes, provided your assembly process can accommodate Cut Tape format. The electrical specifications, mechanical dimensions, and thermal ratings are fully equivalent. Assembly method compatibility should be verified with your manufacturing process.

Q: Are both parts RoHS compliant?

A: Yes. Both the B-02-RTF and B-02-RT are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the physical size of these ferrite beads?

A: Both parts measure 0.165" diameter by 0.236" length (4.20mm x 6.00mm) with axial, split radial bend configuration for through-hole mounting.
