Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L0806C4R7MPWST is determined by strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Inductance value: 4.7 µH
• Inductance tolerance: ±20%
• Package / Case: 0806 (2016 Metric)
• Mounting type: Surface Mount
• DC Resistance: 250 mOhm
• Operating temperature range: -40°C to 105°C
• Self-resonant frequency: 45 MHz
• Inductance test frequency: 7.96 MHz

Secondary Compatibility Factors:

• Current rating must equal or exceed 210 mA
• Shielding configuration: Unshielded
• RoHS3 compliance required
• MSL rating: 1 (Unlimited)

The LB2016T4R7M from Taiyo Yuden meets all primary and secondary criteria, with a higher current rating of 225 mA, providing additional design margin while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The LB2016T4R7M from Taiyo Yuden is a direct functional equivalent to the L0806C4R7MPWST. Both components share identical electrical specifications, mechanical dimensions, and regulatory compliance certifications. The LB2016T4R7M provides a 15 mA higher current rating (225 mA versus 210 mA), which represents improved design margin without introducing any incompatibility.

Both parts carry non-active product statuses: the KEMET part is Obsolete, while the Taiyo Yuden part is designated Not For New Designs. For applications requiring active production support and long-term availability, alternative 4.7 µH inductors in the 0806 package with active product status should be evaluated against the same parameter criteria.

The identical package dimensions, mounting type, and thermal operating range ensure direct PCB layout compatibility. No circuit redesign or board layout modification is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the LB2016T4R7M replace the L0806C4R7MPWST in existing designs?

A: Yes. The LB2016T4R7M meets all electrical and mechanical specifications of the L0806C4R7MPWST. Identical inductance value, tolerance, DC resistance, self-resonant frequency, operating temperature range, and package dimensions ensure direct substitution without circuit modification.

Q: What is the significance of the higher current rating on the LB2016T4R7M?

A: The LB2016T4R7M is rated for 225 mA continuous current compared to the L0806C4R7MPWST at 210 mA. This 15 mA difference provides additional thermal and electrical margin in the application. If the circuit operates at or below 210 mA, both parts perform identically.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components are packaged in the 0806 (2016 Metric) case with dimensions of 0.079" L x 0.063" W (2.00mm x 1.60mm) and maximum seated height of 0.071" (1.80mm). PCB footprints are identical.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the L0806C4R7MPWST and LB2016T4R7M are ROHS3 compliant, carry MSL rating of 1 (Unlimited), and are REACH unaffected. Both share identical ECCN and HTSUS classifications.

Q: What is the difference between the core materials?

A: The L0806C4R7MPWST uses a standard wirewound core, while the LB2016T4R7M uses a drum core with ferrite material. Both configurations deliver the specified 4.7 µH inductance, 250 mOhm DCR, and 45 MHz self-resonant frequency. The core material difference does not affect electrical performance within the specified parameters.

Q: Are there any packaging format differences?

A: The L0806C4R7MPWST packaging format is not specified in the provided data. The LB2016T4R7M is supplied in Tape & Reel (TR) format. Confirm packaging requirements with your procurement specification before ordering.
