Substitute Part Grouping Explanation

Substitute components for the L0806C101KPWST are identified based on strict electrical and mechanical parameter alignment. The following criteria establish substitution validity:

Primary Matching Criteria:

• Inductance value: 100 µH
• Inductance tolerance: ±10%
• Package / Case: 0806 (2016 Metric)
• Core type: Drum Core, Wirewound
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Surface Mount
• Operating temperature range: -40°C to 105°C
• Self-resonant frequency: 8 MHz
• Inductance test frequency: 796 kHz

Secondary Compatibility Factors:

• Current rating must equal or exceed 40 mA
• DC resistance must remain within acceptable circuit design parameters
• RoHS3 compliance and MSL rating must be maintained
• Physical dimensions must conform to 0806 (2016 Metric) specifications

The CB2016T101K from Taiyo Yuden satisfies all primary matching criteria and exceeds the current rating requirement at 170 mA, providing enhanced performance margin for the specified inductance and package class.

Parameter Comparison

Engineering Selection Recommendations

CB2016T101K Selection Basis:

The CB2016T101K from Taiyo Yuden is electrically and mechanically equivalent to the L0806C101KPWST. Both components share identical inductance values, tolerance specifications, package dimensions, and operating temperature ranges. The substitute part exceeds the original current rating specification, providing a 4.25× performance margin (170 mA versus 40 mA).

DC resistance differential of 1.35 Ohm (5.85 Ohm maximum versus 4.5 Ohm) must be evaluated within circuit design parameters. This variance is within typical tolerance bands for ferrite drum core wirewound inductors in this package class and does not preclude functional substitution.

Both components maintain ROHS3 compliance and MSL Level 1 ratings, ensuring compatibility with standard surface mount assembly and storage protocols. The CB2016T101K carries a "Not For New Designs" status, indicating availability for replacement and maintenance applications.

Physical footprint compatibility is confirmed: both parts conform to 0806 (2016 Metric) package specifications with identical length, width, and maximum seated height dimensions, enabling direct PCB layout substitution without redesign.

Frequently Asked Questions (FAQ)

Q: Can the CB2016T101K directly replace the L0806C101KPWST on existing PCBs?

A: Yes. Both components conform to identical 0806 (2016 Metric) package dimensions and mounting specifications. No PCB layout modifications are required for physical substitution.

Q: What is the significance of the higher current rating on the CB2016T101K?

A: The CB2016T101K is rated for 170 mA continuous current, compared to 40 mA for the L0806C101KPWST. This provides a performance margin for circuits operating at or near the original part's current limit. Circuits designed for 40 mA operation remain fully compatible.

Q: How does the DC resistance difference affect circuit performance?

A: The CB2016T101K specifies a maximum DC resistance of 5.85 Ohm versus 4.5 Ohm for the original part. This 1.35 Ohm difference represents approximately 30% higher resistance. Circuit designers must evaluate voltage drop and power dissipation impacts within their specific application parameters.

Q: Are both parts RoHS compliant?

A: Yes. Both the L0806C101KPWST and CB2016T101K are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, meeting standard environmental and handling requirements.

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

A: Obsolete status indicates the L0806C101KPWST is no longer manufactured or supported. Not For New Designs status for the CB2016T101K indicates the manufacturer continues limited production for replacement and maintenance applications but does not recommend it for new product development. Both statuses indicate the need for alternative sourcing strategies.

Q: Are the self-resonant frequency and test frequency identical between both parts?

A: Yes. Both components exhibit an 8 MHz self-resonant frequency and 796 kHz inductance test frequency, confirming electrical equivalence in high-frequency performance characteristics.
