Key Parameters

Substitute Part Grouping Explanation

Substitution of the L0806BR27JSWST is determined by strict equivalence across the following critical parameters:

Inductance Value: 270 nH with ±5% tolerance ensures functional compatibility in circuit applications requiring this specific inductance.

Current Rating: 510 mA continuous current rating must be maintained to prevent thermal stress and component failure under specified load conditions.

DC Resistance: 210 mOhm DCR is a critical electrical parameter affecting power dissipation and circuit performance.

Core Material and Type: Ferrite drum core wirewound construction defines the electromagnetic characteristics and frequency response.

Package and Form Factor: 0806 (2016 Metric) surface mount package ensures mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Shielding Configuration: Unshielded design must be preserved to maintain electromagnetic behavior and prevent unintended coupling effects.

Temperature Range: -40°C to 105°C operating specification must be supported by substitute components.

Compliance Standards: ROHS3 compliance and MSL 1 rating ensure regulatory adherence and handling compatibility.

The LBM2016TR27J from Taiyo Yuden meets all these critical parameters and qualifies as a direct electrical and mechanical substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LBM2016TR27J (Taiyo Yuden)

The LBM2016TR27J provides complete electrical and mechanical equivalence to the L0806BR27JSWST across all specified parameters. Both components share identical inductance, current rating, DC resistance, package dimensions, and operating temperature specifications. The substitute maintains ROHS3 compliance and MSL 1 rating, ensuring regulatory and handling compatibility.

Product Status Consideration: The L0806BR27JSWST is classified as obsolete, while the LBM2016TR27J carries a "Not For New Designs" status. For new product development, alternative inductors with active product status should be evaluated. For legacy system support and production continuity, the LBM2016TR27J is the appropriate substitute.

Packaging Difference: The main part is supplied in Cut Tape (CT) packaging, while the substitute is available in Tape & Reel (TR) format. This difference affects handling and assembly processes but does not impact electrical or mechanical performance.

Quality Factor: The LBM2016TR27J provides documented Q factor specification of 30 @ 25.2 MHz, offering additional performance data not specified for the original part.

Frequently Asked Questions (FAQ)

Q: Can the LBM2016TR27J be used as a direct replacement for the L0806BR27JSWST in existing designs?

A: Yes. The LBM2016TR27J meets all critical electrical parameters including inductance value, current rating, DC resistance, and operating temperature range. Physical dimensions and package form factor are identical, enabling direct PCB layout compatibility.

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

A: Cut Tape (CT) and Tape & Reel (TR) are supply and handling formats that do not affect component electrical or mechanical performance. The selection between these formats depends on assembly process requirements and volume handling capabilities. Both formats contain identical components.

Q: Why is the L0806BR27JSWST marked as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The LBM2016TR27J, though marked "Not For New Designs," remains available from inventory and serves as the appropriate substitute for existing applications requiring this inductance specification.

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

A: No. Both components are ROHS3 compliant, carry MSL 1 rating, and share identical ECCN (EAR99) and HTSUS classifications. Regulatory and environmental compliance requirements are equivalent.

Q: What does the ±5% tolerance specification mean for circuit design?

A: The ±5% tolerance indicates that the actual inductance value will fall within the range of 256.5 nH to 283.5 nH. Circuit designs must account for this tolerance range to ensure proper operation across all component variations.

Q: Is the Q factor specification important for substitution?

A: The Q factor of 30 @ 25.2 MHz provided for the LBM2016TR27J represents the quality factor at the test frequency. This specification was not provided for the original part but does not affect substitution validity, as both components share identical core material, inductance, and resistance characteristics.

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

A: Both components have a self-resonant frequency of 425 MHz, which defines the upper frequency limit for stable inductive behavior. Applications operating below this frequency are suitable for these components.
