L0806C470MPWST Equivalent & Substitute Parts

Part Overview

The L0806C470MPWST is a 47 µH unshielded drum core wirewound inductor manufactured by KEMET in the 0806 (2016 Metric) surface mount package. This component is rated for 60 mA continuous current with a DC resistance of 2.4 Ohm and operates across the temperature range of -40°C to 105°C. The part carries an Obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L0806C470MPWST is determined by the following critical parameters:

• Inductance Value: 47 µH (exact match required)
• Tolerance: ±20% (must be equivalent or tighter)
• Package / Case: 0806 (2016 Metric) (physical compatibility requirement)
• Core Type: Ferrite, Drum Core, Wirewound (functional equivalence)
• Shielding: Unshielded (electromagnetic characteristic match)
• Operating Temperature Range: -40°C to 105°C (thermal compatibility)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

The substitute part CBC2016T470M meets all these criteria. While the substitute exhibits a higher current rating (150 mA versus 60 mA) and increased DC resistance (5.59 Ohm Max versus 2.4 Ohm), these parameters do not preclude substitution in applications where the main part's 60 mA rating is sufficient. The higher DCR of the substitute must be evaluated against circuit performance requirements.

Parameter Comparison

Engineering Selection Recommendations

The CBC2016T470M from Taiyo Yuden is a functionally equivalent substitute for the obsolete L0806C470MPWST. Both components share identical inductance values, package dimensions, operating temperature ranges, and regulatory compliance certifications.

The primary engineering consideration is the difference in DC resistance. The substitute part exhibits a maximum DCR of 5.59 Ohm compared to the main part's 2.4 Ohm. This increased resistance will result in higher power dissipation in applications operating at or near the 60 mA current level. Circuit designers must evaluate whether this additional loss is acceptable within their thermal and efficiency budgets.

The substitute's higher current rating (150 mA) provides additional design margin and does not present a limitation for applications requiring only 60 mA operation.

Both parts carry ROHS3 compliance and unlimited moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the CBC2016T470M be used as a direct replacement for the L0806C470MPWST?

A: Yes, the CBC2016T470M is a direct physical and electrical substitute. Both components occupy the identical 0806 (2016 Metric) package footprint with matching height specifications. The inductance value, tolerance, core type, shielding configuration, and operating temperature range are identical.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The CBC2016T470M exhibits a maximum DC resistance of 5.59 Ohm compared to the main part's 2.4 Ohm. In circuits operating at the 60 mA rating, this represents an additional power dissipation of approximately 0.96 mW (calculated as I²R differential). Circuit performance must be evaluated to determine if this additional loss affects thermal management or circuit efficiency requirements.

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

A: No. Both the L0806C470MPWST and CBC2016T470M are ROHS3 compliant with identical moisture sensitivity levels (MSL 1, Unlimited). Both are suitable for applications requiring RoHS compliance.

Q: Why is the main part marked as Obsolete while the substitute is marked as Not For New Designs?

A: The L0806C470MPWST carries an Obsolete status, indicating it is no longer manufactured or supported by KEMET. The CBC2016T470M carries a Not For New Designs status, indicating that while it remains available from inventory, Taiyo Yuden does not recommend its use in new product development. For new designs, consultation with component suppliers for current production alternatives is advised.

Q: Are the package and mounting specifications identical?

A: Yes. Both components are surface mount inductors in the 0806 (2016 Metric) package with dimensions of 0.079" L x 0.063" W (2.00mm x 1.60mm) and a maximum seated height of 0.071" (1.80mm). PCB footprints and reflow profiles are compatible.
