KEMET B-01-R Ferrite Bead Equivalent & Substitute Parts

Part Overview

The KEMET B-01-R is a signal line ferrite bead designed for electromagnetic interference (EMI) suppression in electronic circuits. This axial, kinked radial bend component operates at 2 Ohms impedance at 1 MHz with a maximum current rating of 5A. The part is currently active in production and maintains ROHS3 compliance. Substitute parts may be required due to inventory constraints, lead time considerations, or specific application packaging requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the B-01-R is determined by strict equivalence across the following critical parameters:

• Impedance specification: 2 Ohms @ 1 MHz (exact match required)
• Filter type: Signal Line (single line configuration)
• Current rating: 5A maximum (equal or greater)
• Operating temperature range: -20°C ~ 70°C (equal or greater)
• Package type: Axial, Kinked Radial Bend (mechanical compatibility)
• Mounting method: Through Hole (PCB assembly compatibility)
• Compliance certifications: ROHS3 Compliant (regulatory equivalence)

The KEMET B-01-RS meets all substitution criteria as a parametric equivalent. Physical dimensions vary between the main part and substitute, but both maintain the same electrical performance and mechanical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the B-01-R and B-01-RS are active production parts manufactured by KEMET with identical electrical specifications and ROHS3 compliance certification. Selection between these parts should be based on:

• PCB layout constraints: The B-01-RS features a shorter axial length (7.50mm vs 13.00mm), making it suitable for space-constrained applications
• Inventory availability: The B-01-RS maintains higher stock levels (14,705 pcs vs 629 pcs)
• Lead time requirements: Either part satisfies equivalent electrical performance for signal line EMI suppression applications

Both parts are suitable for direct substitution in circuits requiring 2 Ohms impedance at 1 MHz with 5A current handling capability across the -20°C to 70°C operating range.

Frequently Asked Questions (FAQ)

Q: Can B-01-RS replace B-01-R in existing designs? A: Yes. Both parts share identical electrical specifications (2 Ohms @ 1 MHz, 5A rating, -20°C ~ 70°C operating range) and mechanical interface (axial, kinked radial bend, through-hole mounting). The primary difference is physical length, which may affect PCB layout but not electrical function.

Q: What is the key difference between B-01-R and B-01-RS? A: The B-01-RS has a shorter axial length (7.50mm vs 13.00mm). Both maintain the same 3.40mm diameter and deliver identical impedance and current handling characteristics.

Q: Are both parts ROHS3 compliant? A: Yes. Both B-01-R and B-01-RS are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing.

Q: Which part should I select for new designs? A: For new designs, consider B-01-RS due to higher inventory availability and compact form factor. Both parts are active production items with equivalent electrical performance.

Q: Can these parts be used interchangeably on the same PCB? A: Electrical performance is identical. Physical dimensions differ, so PCB footprint and lead spacing must accommodate the selected part variant. Verify mechanical clearance before assembly.
