Key Parameters

Substitute Part Grouping Explanation

The FB20022-4B-RC qualifies as a parametric equivalent based on matching all critical electrical and mechanical specifications:

• Impedance Match: 900 Ohms @ 100 MHz (identical)
• Current Rating: 5A maximum (identical)
• Line Configuration: Single-line ferrite bead (identical)
• Physical Package: Radial through-hole with matching dimensions (0.236" Dia, 0.394" Max Height)
• Base Product Series: FB20022 (same base platform)

The primary distinction between these parts is product status and compliance certification, not functional or physical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The FB20022-4B-RC is the direct active equivalent for the obsolete FB20022-4B. Both parts share identical electrical specifications (900 Ohms @ 100 MHz, 5A current rating) and mechanical dimensions (radial through-hole package, 0.236" Dia, 0.394" Max Height).

The FB20022-4B-RC offers improved compliance status: it is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating, compared to the non-compliant status of the original part. This makes the FB20022-4B-RC suitable for applications requiring modern environmental and regulatory compliance.

For designs currently using FB20022-4B, direct substitution with FB20022-4B-RC requires no circuit modifications or re-qualification, as all functional and physical parameters remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can FB20022-4B-RC be used as a direct replacement for FB20022-4B?

A: Yes. Both parts are identical in impedance (900 Ohms @ 100 MHz), current rating (5A), and physical dimensions (radial through-hole, 0.236" Dia, 0.394" Max Height). No circuit changes are required.

Q: What is the difference between FB20022-4B and FB20022-4B-RC?

A: The primary differences are product status and compliance certifications. FB20022-4B is obsolete and RoHS non-compliant. FB20022-4B-RC is active and ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Are the physical packages identical?

A: Yes. Both parts use radial through-hole packaging with identical dimensions: 0.236" diameter and 0.394" maximum height.

Q: Does the packaging format affect electrical performance?

A: No. The FB20022-4B-RC is available in bulk packaging, but this is a distribution format only and does not affect the component's electrical characteristics or performance in circuit.

Q: What compliance advantages does FB20022-4B-RC offer?

A: FB20022-4B-RC meets ROHS3 compliance requirements and carries MSL 1 (Unlimited) moisture sensitivity rating, making it suitable for applications with modern environmental and regulatory requirements.
