CIB41P800NE Ferrite Bead Equivalent & Substitute Parts

Part Overview

The CIB41P800NE is a 1806 (4516 Metric) surface mount ferrite bead manufactured by Samsung Electro-Mechanics. This component provides 80 Ohms impedance at 100 MHz with a maximum current rating of 1A and DC resistance of 30mOhm. The part is classified as obsolete, necessitating identification of active equivalent components for ongoing design and procurement requirements. Substitute parts must maintain electrical performance within specified operating parameters and physical compatibility with existing PCB layouts.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CIB41P800NE is determined by the following critical parameters:

Electrical Compatibility:

• Impedance @ 100 MHz: 80 Ohms (±tolerance acceptable within ferrite bead specifications)
• Current Rating: 1A minimum
• DC Resistance: 30mOhm maximum

Physical Compatibility:

• Package: 1806 (4516 Metric) surface mount form factor
• Mounting Type: Surface Mount
• Height and dimensional alignment with PCB layout

Regulatory & Environmental:

• RoHS3 Compliance
• Operating Temperature Range: Minimum -40°C to 125°C (CIB41P800NE operates -55°C to 125°C)
• REACH Unaffected status

The substitute part MI1806J800R-10 meets these criteria with equivalent electrical performance and identical physical package specifications.

Engineering Selection Recommendations

Primary Substitute: MI1806J800R-10 (Laird-Signal Integrity Products)

The MI1806J800R-10 is the direct equivalent for CIB41P800NE replacement. Selection rationale:

• Electrical Performance: Impedance of 78 Ohms at 100 MHz provides equivalent filtering performance within standard ferrite bead tolerance bands. Current rating and DC resistance specifications are identical.

• Physical Compatibility: Identical 1806 (4516 Metric) package dimensions and surface mount configuration enable direct PCB layout substitution without redesign.

• Regulatory Compliance: Both components maintain ROHS3 compliance and REACH Unaffected status, satisfying supply chain and environmental requirements.

• Product Status: MI1806J800R-10 is active production, ensuring long-term availability and supply chain continuity compared to the obsolete CIB41P800NE.

• Operating Temperature: MI1806J800R-10 operates across -40°C to 125°C, which covers standard industrial and commercial temperature ranges. Applications requiring the full -55°C lower limit of CIB41P800NE must evaluate specific thermal requirements.

• Packaging: MI1806J800R-10 is supplied in Tape & Reel (TR) format with 8721 pieces in stock, supporting both prototype and production volume requirements.

Frequently Asked Questions (FAQ)

Q: Can MI1806J800R-10 directly replace CIB41P800NE in existing designs?

A: Yes. Both components share identical 1806 (4516 Metric) package dimensions, surface mount configuration, current rating (1A), and DC resistance (30mOhm). The impedance difference of 2 Ohms (80 Ohms vs. 78 Ohms at 100 MHz) falls within standard ferrite bead manufacturing tolerances and does not affect functional performance in typical EMI filtering applications.

Q: What is the impedance tolerance difference between these parts?

A: The CIB41P800NE specifies 80 Ohms at 100 MHz, while MI1806J800R-10 specifies 78 Ohms at 100 MHz. This 2.5% difference is within acceptable ferrite bead performance variation and does not require circuit redesign for standard power and signal line filtering applications.

Q: Are there packaging differences between the two parts?

A: CIB41P800NE is supplied in Cut Tape (CT) & Digi-Reel® format, while MI1806J800R-10 is supplied in Tape & Reel (TR) format. Both are surface mount compatible. Packaging format selection depends on assembly process requirements and volume needs.

Q: Does the height difference affect PCB layout?

A: The MI1806J800R-10 has a maximum height of 0.063" (1.60mm) compared to CIB41P800NE at 0.071" (1.80mm). This 0.008" (0.20mm) reduction is negligible for PCB clearance and does not require layout modification.

Q: What is the operating temperature consideration for substitution?

A: CIB41P800NE operates from -55°C to 125°C, while MI1806J800R-10 operates from -40°C to 125°C. For applications requiring operation below -40°C, the lower temperature limit of MI1806J800R-10 must be evaluated against specific system requirements.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both CIB41P800NE and MI1806J800R-10 are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic component procurement.
