Key Parameters

Substitute Part Grouping Explanation

Substitution of the L0806B120JSWST is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters:

• Inductance value: 12 µH
• Inductance tolerance: ±5%
• Current rating: 200 mA minimum
• DC resistance: 1.4 Ohm
• Self resonant frequency: 23 MHz
• Operating temperature range: -40°C to 105°C minimum

Mechanical Parameters:

• Package / Case: 0806 (2016 Metric)
• Core type: Ferrite drum core, wirewound
• Shielding: Unshielded
• Mounting type: Surface mount
• Physical dimensions: 0.079" L x 0.063" W (2.00mm x 1.60mm)
• Maximum seated height: 0.071" (1.80mm)

Compliance Parameters:

• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must match all electrical specifications, mechanical form factor, and compliance certifications to ensure direct interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The LBM2016T120J manufactured by Taiyo Yuden is a direct electrical and mechanical equivalent to the obsolete L0806B120JSWST. Both components satisfy identical specifications across inductance, current rating, DC resistance, package form factor, and operating temperature range.

Product Status Consideration: The L0806B120JSWST is classified as obsolete, while the LBM2016T120J is classified as "Not For New Designs." For new product development, alternative sources or newer inductor series should be evaluated. For legacy system maintenance and repair, the LBM2016T120J provides functional continuity with the original specification.

Compliance Alignment: Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with current manufacturing and environmental standards.

Packaging Consideration: The L0806B120JSWST is supplied in Cut Tape (CT) packaging, while the LBM2016T120J 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 LBM2016T120J be used as a direct replacement for the L0806B120JSWST?

A: Yes. Both components are electrically and mechanically equivalent. They share identical inductance (12 µH), current rating (200 mA), DC resistance (1.4 Ohm), package form factor (0806/2016 Metric), and operating temperature range (-40°C to 105°C). Physical dimensions and mounting characteristics are identical.

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 are unchanged; only the procurement and handling format differs.

Q: Are there any performance differences between the KEMET and Taiyo Yuden parts?

A: The Taiyo Yuden LBM2016T120J specifies a Q factor of 25 at 2.52 MHz, while the KEMET L0806B120JSWST does not provide this specification. All other electrical parameters, including inductance, tolerance, current rating, DC resistance, and self resonant frequency, are identical. The Q factor specification provides additional quality information but does not affect substitution compatibility.

Q: What compliance certifications apply to both parts?

A: Both the L0806B120JSWST and LBM2016T120J are ROHS3 compliant and REACH unaffected. Both carry moisture sensitivity level 1 (unlimited), indicating no special moisture handling requirements during storage or assembly.

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

A: Both components have a self resonant frequency of 23 MHz. Applications operating near or above this frequency may experience degraded inductor performance. The inductance test frequency is specified at 2.52 MHz, which is well below the self resonant frequency and represents the intended operating point for inductance specification.
