Substitute Part Grouping Explanation

Substitution of the L0806C101MDWST is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

  • Inductance value: 100 µH
  • Current rating: 170 mA minimum
  • Package format: 0806 (2016 Metric)
  • Mounting type: Surface Mount
  • Operating temperature range: -40°C to 105°C minimum
  • Self-resonant frequency: 8 MHz
  • Inductance test frequency: 796 kHz
  • Shielding configuration: Unshielded

Allowable Variation Parameters:

  • DC Resistance (DCR): Tolerance within component specification limits
  • Inductance tolerance: ±10% to ±20%
  • Core material: Wirewound or drum core wirewound construction

The CB2016T101K from Taiyo Yuden meets all mandatory matching parameters and is therefore classified as a direct functional equivalent.

Engineering Selection Recommendations

The CB2016T101K from Taiyo Yuden is a direct functional equivalent to the obsolete L0806C101MDWST. Both components are ROHS3 compliant and operate within identical electrical and thermal specifications.

Selection Considerations:

The CB2016T101K exhibits a higher maximum DC resistance of 5.85 Ohm compared to the L0806C101MDWST at 4.5 Ohm. This 1.35 Ohm increase results in proportionally higher resistive losses in the inductor. Circuit designs dependent on the lower DCR specification of the original part require thermal and efficiency analysis to confirm the substitute is acceptable for the intended application.

The CB2016T101K features a tighter inductance tolerance of ±10% versus the original part's ±20%, providing improved consistency in inductance value across production batches.

The CB2016T101K is classified as "Not For New Designs" by the manufacturer, indicating limited long-term availability. For new product development, alternative suppliers should be evaluated for extended lifecycle support.

Both components are surface mount compatible with identical package dimensions and mounting footprints, enabling direct PCB layout substitution without redesign.

Frequently Asked Questions (FAQ)

Q: Can the CB2016T101K be used as a direct replacement for the L0806C101MDWST?

A: Yes. Both components share identical inductance values, current ratings, saturation current, self-resonant frequency, operating temperature range, package format, and physical dimensions. The CB2016T101K is electrically and mechanically compatible for direct substitution on existing PCB designs.

Q: What is the significance of the higher DC resistance in the CB2016T101K?

A: The CB2016T101K exhibits a maximum DC resistance of 5.85 Ohm compared to 4.5 Ohm in the L0806C101MDWST. This 30% increase in resistance generates additional heat dissipation under load. Applications sensitive to resistive losses or thermal performance require evaluation to confirm the substitute meets design requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the L0806C101MDWST and CB2016T101K are ROHS3 compliant, meeting environmental and hazardous substance restrictions for electronic components.

Q: What is the difference between the inductance tolerances?

A: The L0806C101MDWST specifies ±20% inductance tolerance, while the CB2016T101K specifies ±10%. The tighter tolerance of the substitute part provides improved consistency in inductance values across production lots, which may benefit applications requiring precise inductance specifications.

Q: Are the physical dimensions identical?

A: Yes. Both components are packaged in the 0806 (2016 Metric) format with identical length, width, and maximum seated height dimensions of 2.00mm x 1.60mm x 1.80mm respectively. No PCB layout modifications are required for substitution.

Q: What is the "Not For New Designs" status of the CB2016T101K?

A: This designation indicates the manufacturer does not recommend the CB2016T101K for incorporation into new product designs due to limited future availability or planned discontinuation. For new development projects, alternative suppliers and part numbers should be evaluated for extended lifecycle support.

Q: Can these inductors be used interchangeably in high-frequency applications?

A: Both components share identical self-resonant frequency specifications of 8 MHz and are tested at 796 kHz. They are suitable for equivalent high-frequency performance within these specified parameters.
