L0806C220MPWST Equivalent & Substitute Parts

Part Overview

The L0806C220MPWST is a 22 µH unshielded drum core wirewound inductor manufactured by KEMET in the 0806 (2016 Metric) surface mount package. This component is rated for 105 mA continuous current with 1Ohm DC resistance and operates across the temperature range of -40°C to 105°C. The part is classified as Obsolete, necessitating identification of equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain the same inductance value, package footprint, and core material while accommodating variations in current rating and DC resistance within acceptable design parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L0806C220MPWST is determined by strict adherence to the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 22 µH
• Inductance tolerance: ±20%
• Package / Case: 0806 (2016 Metric)
• Material - Core: Ferrite
• Shielding: Unshielded
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C ~ 105°C
• Inductance Frequency - Test: 2.52 MHz

Allowable Variation Parameters:

• Current Rating (Amps): Substitute must equal or exceed the original 105 mA rating
• DC Resistance (DCR): Substitute values may vary based on design requirements and thermal considerations
• Frequency - Self Resonant: Substitute must match 16 MHz
• RoHS and REACH compliance status must be maintained

The CBC2016T220M from Taiyo Yuden qualifies as a substitute part because it maintains all mandatory matching parameters while providing enhanced current handling capability (240 mA) and saturation current specification (250 mA).

Parameter Comparison

Engineering Selection Recommendations

The CBC2016T220M from Taiyo Yuden serves as a direct substitute for the obsolete L0806C220MPWST. Both components maintain identical inductance specifications, package dimensions, core material composition, and operating temperature ranges. The substitute part provides superior current handling capacity at 240 mA compared to the original 105 mA rating, with saturation current specification of 250 mA.

The increased DC resistance of the CBC2016T220M (2.34 Ohm maximum versus 1 Ohm) must be evaluated within the context of the specific application circuit. Applications requiring minimal power dissipation or precise impedance matching should account for this parameter difference during design validation.

Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current manufacturing standards. The CBC2016T220M is classified as Not For New Designs but remains available in production quantities (16,200 pieces in stock), making it suitable for legacy system support and field replacement applications.

Frequently Asked Questions (FAQ)

Q: Can the CBC2016T220M be used as a direct replacement for the L0806C220MPWST in existing designs?

A: The CBC2016T220M maintains identical inductance value, package footprint, core material, and operating temperature range. The increased current rating (240 mA versus 105 mA) and higher DC resistance (2.34 Ohm maximum versus 1 Ohm) must be evaluated within the specific circuit application to confirm compatibility.

Q: What is the significance of the higher DC resistance in the substitute part?

A: The CBC2016T220M exhibits 2.34 Ohm maximum DC resistance compared to 1 Ohm in the original part. This parameter affects power dissipation and circuit impedance. Applications sensitive to resistive losses or requiring precise impedance characteristics should account for this difference during circuit analysis.

Q: Are both parts physically identical in package dimensions?

A: Both the L0806C220MPWST and CBC2016T220M utilize the 0806 (2016 Metric) surface mount package with identical physical dimensions: 0.079" L x 0.063" W (2.00mm x 1.60mm) and maximum seated height of 0.071" (1.80mm). PCB footprints are interchangeable.

Q: What is the difference between the current rating and saturation current specifications?

A: The current rating (240 mA for CBC2016T220M) represents the continuous operating current limit. The saturation current (250 mA) indicates the current level at which the inductor begins to exhibit nonlinear behavior due to core saturation. The saturation current specification is provided only for the substitute part.

Q: Do both parts meet current regulatory compliance requirements?

A: Both the L0806C220MPWST and CBC2016T220M are ROHS3 compliant and REACH unaffected, meeting current regulatory standards for electronic component manufacturing and use.

Q: What is the moisture sensitivity level, and why is it relevant?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions. These components do not require special moisture control during storage, handling, or assembly processes.

Q: How does the inductance tolerance affect circuit design?

A: Both parts specify ±20% inductance tolerance. Circuit designs must account for this tolerance range when calculating filter response, resonant frequencies, or impedance-dependent functions. The actual inductance value may vary between 17.6 µH and 26.4 µH across the production range.
