L0806C330MPWST Equivalent & Substitute Parts

Part Overview

The L0806C330MPWST is a 33 µH unshielded drum core wirewound inductor manufactured by KEMET in the 0806 (2016 Metric) surface mount package. This component is rated for 85 mA continuous current with a DC resistance of 1.7 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 design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution of the L0806C330MPWST is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 33 µH (exact match required)
• Package / Case: 0806 (2016 Metric) (physical compatibility)
• Core type: Drum Core, Wirewound with Ferrite material (functional equivalence)
• Shielding: Unshielded (electromagnetic behavior)
• Operating temperature range: -40°C ~ 105°C (environmental compatibility)
• Mounting type: Surface Mount (assembly compatibility)

Allowable Variation Parameters:

• Current Rating: The substitute may exceed the original 85 mA rating, provided the application does not require the lower current specification
• DC Resistance (DCR): Variation is acceptable within the constraints of circuit design requirements
• Tolerance: Different tolerance specifications are acceptable if circuit performance permits

The CBC2016T330K from Taiyo Yuden meets all critical matching parameters and qualifies as a functional substitute.

Parameter Comparison

Engineering Selection Recommendations

The CBC2016T330K from Taiyo Yuden is a qualified substitute for the obsolete L0806C330MPWST. Both components share identical inductance values, package dimensions, core materials, and operating temperature ranges. Both are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring equivalent environmental and regulatory compliance.

The CBC2016T330K exhibits a higher current rating (220 mA versus 85 mA) and increased DC resistance (3.64 Ohm Max versus 1.7 Ohm). These differences must be evaluated within the specific circuit application. The higher current rating provides additional design margin in applications where the original 85 mA specification is not a limiting constraint. The increased DC resistance will result in higher power dissipation and should be verified against thermal and efficiency requirements.

The CBC2016T330K carries a product status of "Not For New Designs," indicating limited long-term availability. For new designs requiring extended procurement windows, alternative sources should be evaluated beyond this single substitute.

Frequently Asked Questions (FAQ)

Q: Can the CBC2016T330K be used as a direct replacement for the L0806C330MPWST in existing assemblies?

A: Physical and electrical compatibility is confirmed for the 33 µH inductance value and 0806 (2016 Metric) package. However, the increased DC resistance (3.64 Ohm Max versus 1.7 Ohm) will affect circuit performance. Circuit simulation or testing is required to confirm functional equivalence in the specific application.

Q: What is the impact of the higher current rating on the CBC2016T330K?

A: The 220 mA current rating of the CBC2016T330K exceeds the original 85 mA specification. This provides additional design margin and does not create incompatibility. Applications operating below 85 mA will function identically to the original part.

Q: Are there differences in tolerance specifications between these parts?

A: Yes. The L0806C330MPWST specifies ±20% tolerance, while the CBC2016T330K specifies ±10% tolerance. The tighter tolerance of the substitute part provides improved inductance accuracy and may benefit circuit performance.

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

A: Both components are ROHS3 compliant, carry EAR99 ECCN classification, and share identical HTSUS codes. Both are rated MSL 1 (Unlimited) for moisture sensitivity. Regulatory and compliance requirements are equivalent.

Q: What is the significance of the "Not For New Designs" status of the CBC2016T330K?

A: This designation indicates the substitute part has limited availability and may not be suitable for long-term production programs. For new designs requiring extended component availability, additional alternative sources should be identified.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components share identical dimensions: 0.079" L x 0.063" W (2.00mm x 1.60mm) with a maximum seated height of 0.071" (1.80mm). PCB layout and assembly compatibility are equivalent.
