Engineering Selection Recommendations

The LBM2016T680J from Taiyo Yuden is a direct electrical and mechanical equivalent to the obsolete L0806B680JSWST. Both components satisfy identical specifications across inductance, current rating, DC resistance, package dimensions, and operating temperature range.

Product Status Consideration: The L0806B680JSWST is classified as Obsolete, while the LBM2016T680J is classified as Not For New Designs. For new product development, neither part should be selected. For legacy system maintenance and repair where the L0806B680JSWST is required, the LBM2016T680J provides functional continuity.

Compliance Alignment: Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and REACH unaffected status, ensuring regulatory compatibility in existing applications.

Packaging Difference: The L0806B680JSWST is supplied in Cut Tape (CT) packaging, while the LBM2016T680J is supplied in Tape & Reel (TR) packaging. This difference affects procurement and assembly processes but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can the LBM2016T680J be used as a direct replacement for the L0806B680JSWST in existing designs?

A: Yes. The LBM2016T680J meets all electrical specifications (68 µH inductance, 90 mA current rating, 7 Ohm DCR) and mechanical requirements (0806 package, surface mount, ferrite drum core, unshielded). Both components operate identically across the -40°C to 105°C temperature range.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging supplies individual components on tape segments, typically for lower-volume applications. Tape & Reel (TR) packaging supplies components on continuous reels, optimized for high-volume automated assembly. The electrical and mechanical properties of the component remain unchanged.

Q: Are there compliance differences between these two parts?

A: No. Both the L0806B680JSWST and LBM2016T680J maintain identical ROHS3 compliance, MSL 1 rating, and REACH unaffected status.

Q: Why is the Q factor specified for the substitute but not the main part?

A: The LBM2016T680J datasheet provides Q @ 2.52 MHz (20), while the L0806B680JSWST does not specify this parameter. This additional data does not affect substitution eligibility, as both components are tested at the same frequency (2.52 MHz) and exhibit the same self-resonant frequency (11 MHz).

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

A: Both components are rated to 11 MHz self-resonant frequency and are tested at 2.52 MHz. Application suitability depends on circuit requirements at the operating frequency. The electrical equivalence ensures performance parity within specified frequency limits.

Q: What inventory considerations apply to these parts?

A: The L0806B680JSWST has 2307 pieces in stock (Cut Tape), while the LBM2016T680J has 2300 pieces in stock (Tape & Reel). Availability is comparable, but packaging format should be confirmed against assembly requirements.
