Key Parameters

Substitute Part Grouping Explanation

Substitution of the L0806B470JSWST is determined by strict equivalence across the following critical parameters:

Primary Equivalence Criteria:

• Inductance value: 47 µH with ±5% tolerance
• Package / Case: 0806 (2016 Metric) surface mount
• Core type: Ferrite drum core, wirewound, unshielded
• Operating temperature range: -40°C to 105°C minimum
• Mounting type: Surface mount

Secondary Compatibility Parameters:

• Current rating: Minimum 115 mA (substitute must support circuit current requirements)
• DC resistance: Maximum 4.1 Ohm (acceptable variance from 3.9 Ohm baseline)
• Self resonant frequency: Minimum 13 MHz

The substitute part LBM2016T470J from Taiyo Yuden meets all primary equivalence criteria and operates within acceptable secondary parameter ranges for direct substitution in applications where the original KEMET component is no longer available.

Parameter Comparison

Engineering Selection Recommendations

The LBM2016T470J from Taiyo Yuden is a direct substitute for the obsolete L0806B470JSWST. Both components are ROHS3 compliant and carry MSL Level 1 rating, indicating equivalent environmental and regulatory compliance. The substitute part maintains identical package dimensions, inductance value, and operating temperature specifications.

The LBM2016T470J carries a product status of "Not For New Designs," indicating it is also subject to lifecycle constraints. However, it remains available in production quantities (2930 Pcs in stock) and provides functional equivalence for replacement and maintenance applications.

The 5 mA reduction in current rating (115 mA versus 120 mA) and 0.2 Ohm increase in DC resistance are within acceptable engineering tolerances for most applications. The substitute part provides documented Q factor performance (20 @ 2.52 MHz), which is not specified for the original component.

Frequently Asked Questions (FAQ)

Q: Can the LBM2016T470J be used as a direct replacement for the L0806B470JSWST?

A: Yes. Both components share identical inductance values (47 µH ±5%), package dimensions (0806 / 2016 Metric), core material (ferrite), and operating temperature range (-40°C to 105°C). The substitute meets all primary equivalence criteria for direct substitution in surface mount applications.

Q: What is the significance of the 5 mA current rating difference?

A: The L0806B470JSWST is rated for 120 mA continuous current, while the LBM2016T470J is rated for 115 mA. This 4.2% reduction is within typical component tolerance ranges. Applications operating at or below 115 mA experience no functional impact. Applications requiring the full 120 mA rating must evaluate circuit current requirements against the substitute's specification.

Q: How does the 0.2 Ohm increase in DC resistance affect circuit performance?

A: The L0806B470JSWST specifies 3.9 Ohm DCR, while the LBM2016T470J specifies 4.1 Ohm DCR. This 5.1% increase results in proportionally higher resistive losses in the inductor. For most filtering and energy storage applications, this variance is negligible. High-efficiency power conversion circuits should evaluate the impact on overall system efficiency.

Q: Are both components RoHS compliant?

A: Yes. Both the L0806B470JSWST and LBM2016T470J are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity ratings, indicating equivalent environmental qualification and handling requirements.

Q: What packaging formats are available for the substitute part?

A: The LBM2016T470J is supplied in Tape & Reel (TR) format, while the original L0806B470JSWST is available in Cut Tape (CT) format. Both formats are compatible with standard surface mount assembly equipment. Procurement should specify the required packaging format based on production volume and assembly process requirements.

Q: Why is the substitute part also marked as "Not For New Designs"?

A: The LBM2016T470J carries a "Not For New Designs" status, indicating that Taiyo Yuden has discontinued active development and long-term support for this component. This status applies to both the original and substitute parts, reflecting industry-wide lifecycle management of legacy inductor products. The substitute remains available for production and maintenance applications but should not be selected for new product development without evaluation of alternative active components.
