Key Parameters

Substitute Part Grouping Explanation

Substitution of the L0806C100MPWST is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 10 µH
• Package / Case: 0806 (2016 Metric)
• Core type: Ferrite, Drum Core, Wirewound
• Shielding configuration: Unshielded
• Operating temperature range: -40°C ~ 105°C
• Self resonant frequency: 32 MHz
• Mounting type: Surface Mount

Allowable Variation Parameters:

• Current rating: Substitute must equal or exceed 155 mA
• DC resistance: Substitute must not exceed 500 mOhm nominal specification
• Tolerance: ±20% is acceptable
• Moisture sensitivity level: MSL 1 is acceptable

The substitute part CB2016T100M from Taiyo Yuden meets all mandatory matching criteria and provides enhanced current handling capability (520 mA) while maintaining DC resistance within acceptable limits (650 mOhm maximum).

Parameter Comparison

Engineering Selection Recommendations

The CB2016T100M from Taiyo Yuden is a direct functional equivalent to the obsolete L0806C100MPWST. Both components are ROHS3 compliant and carry MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols.

The CB2016T100M provides superior current handling capability at 520 mA compared to the original 155 mA specification, offering design margin for applications with variable or future current requirements. The increased DC resistance of 650 mOhm maximum represents a 30% increase over the original 500 mOhm specification; this difference must be evaluated within the context of the specific circuit application to ensure thermal and performance requirements remain satisfied.

The Taiyo Yuden part carries a product status of "Not For New Designs," indicating limited long-term availability. For new design initiatives, consultation with component suppliers for current-generation alternatives in the 10 µH, 0806 package category is advised.

Frequently Asked Questions (FAQ)

Q: Can the CB2016T100M be used as a direct replacement for the L0806C100MPWST in existing assemblies?

A: Yes. Both components share identical inductance values, package dimensions, operating temperature ranges, and self-resonant frequencies. The CB2016T100M is pin-compatible and footprint-compatible with the L0806C100MPWST.

Q: What is the significance of the higher current rating in the CB2016T100M?

A: The CB2016T100M is rated for 520 mA continuous current compared to 155 mA for the original part. This provides additional design margin and allows the substitute to operate in applications with higher current demands. However, the increased DC resistance must be factored into thermal calculations.

Q: How does the increased DC resistance of the CB2016T100M affect circuit performance?

A: The CB2016T100M specifies a maximum DC resistance of 650 mOhm compared to 500 mOhm for the L0806C100MPWST. This 150 mOhm difference results in increased resistive losses and heat generation proportional to the square of the current flowing through the inductor. Circuit designers must verify that this resistance increase does not compromise performance specifications, particularly in low-noise or high-efficiency applications.

Q: Are both parts suitable for automated assembly processes?

A: Yes. Both the L0806C100MPWST and CB2016T100M are surface mount components in 0806 (2016 Metric) packages with MSL 1 rating, compatible with standard pick-and-place equipment and reflow soldering processes.

Q: What is the difference between the product status designations "Obsolete" and "Not For New Designs"?

A: "Obsolete" indicates the L0806C100MPWST is no longer manufactured and existing inventory is limited. "Not For New Designs" for the CB2016T100M indicates the manufacturer is not recommending this part for new circuit designs, though it remains available from existing stock. Both statuses indicate limited long-term availability.

Q: Are there compliance or certification differences between these parts?

A: Both components are ROHS3 compliant and carry MSL 1 rating. The L0806C100MPWST carries REACH Unaffected status, while the CB2016T100M does not specify REACH status in the provided data. Both are classified under ECCN EAR99.
