KEMET B-06-R-25 Ferrite Bead Equivalent & Substitute Parts

Part Overview

The KEMET B-06-R-25 is a radial ferrite bead designed for signal line filtering applications. This component provides 40 Ohms of impedance at 10 MHz with a maximum current rating of 5A, operating across a temperature range of -20°C to 70°C. The part is ROHS3 compliant and currently active in production. Substitute parts may be required due to inventory constraints, design revisions, or procurement optimization across equivalent product lines.

Substitute Part Grouping Explanation

The KEMET B-06-R-25 and B-06-R-50 are parametric equivalents within the BEAD L series. Both parts share identical electrical specifications: 40 Ohms impedance at 10 MHz, 1 signal line configuration, and 5A maximum current rating. Both operate across the same temperature range (-20°C to 70°C) and maintain ROHS3 compliance. The primary difference between these parts is the physical height dimension: B-06-R-25 has a maximum height of 0.236" (6.00mm), while B-06-R-50 has a maximum height of 0.394" (10.00mm). Both maintain identical footprint dimensions of 0.236" L x 0.276" W (6.00mm x 7.00mm). Substitution is valid when the increased height of the B-06-R-50 does not conflict with board layout constraints.

Parameter Comparison

Engineering Selection Recommendations

Both B-06-R-25 and B-06-R-50 are active production parts with identical electrical performance and regulatory compliance. Selection between these parts depends solely on available board height clearance. The B-06-R-25, with its 6.00mm maximum height, is suitable for space-constrained applications. The B-06-R-50, with its 10.00mm maximum height, may be selected when inventory availability of the primary part is limited and vertical clearance permits. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications.

Frequently Asked Questions (FAQ)

Q: Can B-06-R-50 be used as a direct replacement for B-06-R-25?

A: Yes, provided the increased height of 0.394" (10.00mm) versus 0.236" (6.00mm) does not violate board layout or enclosure constraints. All electrical parameters and compliance certifications are identical.

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

A: No. Both parts provide 40 Ohms impedance at 10 MHz, support 5A maximum current, and operate across -20°C to 70°C. Electrical performance is equivalent.

Q: What is the footprint difference between B-06-R-25 and B-06-R-50?

A: The footprint dimensions are identical at 0.236" L x 0.276" W (6.00mm x 7.00mm). The only dimensional difference is the component height.

Q: Are both parts RoHS compliant?

A: Yes. Both B-06-R-25 and B-06-R-50 are ROHS3 compliant and REACH unaffected.

Q: Which part should be selected for new designs?

A: Selection should be based on available vertical clearance on the PCB. If space permits, either part is acceptable. Verify height constraints against your specific board layout before finalizing component selection.
