L0806B390JSWST Equivalent & Substitute Parts

Part Overview

The L0806B390JSWST is a 39 µH unshielded drum core wirewound inductor manufactured by KEMET in the 0806 (2016 Metric) surface mount package. This component is rated for 120 mA continuous current with a DC resistance of 3.9 Ohm and operates across the temperature range of -40°C to 105°C. The part is classified as Obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L0806B390JSWST is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Inductance value (39 µH), inductance tolerance (±5%), current rating (120 mA), and DC resistance (3.9 Ohm) must be identical. These parameters define the component's functional role in the circuit.

Mechanical Compatibility: Package designation (0806 / 2016 Metric), mounting type (Surface Mount), and physical dimensions (0.079" L × 0.063" W, 2.00mm × 1.60mm length and width; 0.071" maximum seated height / 1.80mm) ensure PCB footprint compatibility without layout modification.

Environmental & Compliance Requirements: Operating temperature range (-40°C to 105°C), core material (Ferrite, Unshielded), RoHS3 compliance, and MSL rating (1 - Unlimited) must be maintained to preserve reliability and regulatory certification status.

The substitute part LBM2016T390J meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The LBM2016T390J (Taiyo Yuden) is a direct functional equivalent to the L0806B390JSWST (KEMET) based on complete parameter alignment across electrical, mechanical, and environmental specifications. Both components are subject to product lifecycle restrictions: the original part is Obsolete, while the substitute is designated Not For New Designs. This status alignment indicates both parts are at end-of-life phases.

Selection between these parts should be based on:

Inventory Availability: The L0806B390JSWST has 3236 pieces in stock, while the LBM2016T390J has 1935 pieces available. Procurement decisions should account for current stock levels and supply chain requirements.

Packaging Format: The L0806B390JSWST is supplied in Cut Tape (CT) format, while the LBM2016T390J is supplied in Tape & Reel (TR) format. Manufacturing processes and assembly equipment compatibility may influence packaging selection.

Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL rating 1 (Unlimited), ensuring equivalent environmental and regulatory standing for applications requiring these certifications.

For applications requiring active component sourcing, neither part is recommended for new designs due to their obsolete or restricted status. Long-term production planning should identify alternative inductors from current product lines that maintain the specified 39 µH, 120 mA, 3.9 Ohm parameters in the 0806 package format.

Frequently Asked Questions (FAQ)

Q: Can the LBM2016T390J be used as a direct replacement for the L0806B390JSWST on existing PCBs?

A: Yes. Both components share identical package dimensions (0806 / 2016 Metric), physical footprint (0.079" × 0.063"), and mounting type (Surface Mount). No PCB layout modification is required for substitution.

Q: Are the electrical characteristics identical between these two parts?

A: Yes. Both inductors provide 39 µH inductance at ±5% tolerance, support 120 mA current rating, and exhibit 3.9 Ohm DC resistance. Operating temperature range (-40°C to 105°C), self-resonant frequency (14 MHz), and test frequency (2.52 MHz) are identical.

Q: What is the significance of the different product status designations?

A: The L0806B390JSWST is classified as Obsolete, indicating it is no longer manufactured. The LBM2016T390J is designated Not For New Designs, indicating limited availability and restricted use for new product development. Both statuses indicate end-of-life phases and suggest that long-term applications should transition to current production alternatives.

Q: Does packaging format (Cut Tape vs. Tape & Reel) affect electrical performance?

A: No. Packaging format affects only supply chain logistics and assembly line compatibility. Electrical and mechanical specifications remain identical regardless of whether the component is supplied in Cut Tape or Tape & Reel format.

Q: What compliance certifications apply to both parts?

A: Both the L0806B390JSWST and LBM2016T390J are ROHS3 compliant and carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture bake-out requirement prior to soldering. Both parts are classified as EAR99 for export control purposes.

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

A: Yes, within the specified frequency range. Both components are rated for operation up to 14 MHz self-resonant frequency and are tested at 2.52 MHz. Circuit performance depends on application-specific frequency requirements and impedance matching, not on the choice between these equivalent parts.
