Frequently Asked Questions (FAQ)

Q: Can the LBM2016T270J be used as a direct replacement for the L0806B270JSWST in existing designs?

A: Yes. The LBM2016T270J meets all critical electrical and mechanical parameters: 27 µH inductance, 130 mA current rating, 3.2 Ohm DC resistance, 0806 (2016 Metric) package, and identical operating temperature range. No circuit redesign is required.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape packaging supplies components in individual strips suitable for low-volume or manual assembly. Tape & Reel packaging supplies components on continuous reels optimized for automated pick-and-place assembly equipment. Selection depends on production volume and assembly process capabilities.

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

A: No. Both the L0806B270JSWST and LBM2016T270J are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). Both carry identical ECCN (EAR99) and HTSUS (8504.50.8000) classifications.

Q: Why is the L0806B270JSWST classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support for this part number. The LBM2016T270J provides functional continuity for applications requiring 27 µH inductors in the 0806 package format.

Q: Does the LBM2016T270J provide any additional technical data?

A: Yes. The LBM2016T270J specifies a Q factor of 25 at 2.52 MHz, providing additional performance characterization. The L0806B270JSWST does not include Q factor specification in available documentation.
