L0806C3R3MPWST Equivalent & Substitute Parts

Part Overview

The L0806C3R3MPWST is a 3.3 µH unshielded drum core wirewound inductor manufactured by KEMET in the 0806 (2016 Metric) surface mount package. This component is rated for 280 mA continuous current with a DC resistance of 200 mOhm 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 L0806C3R3MPWST is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

Inductance value: 3.3 µH
Inductance tolerance: ±20%
Package / Case: 0806 (2016 Metric)
Mounting type: Surface Mount
Core material: Ferrite
Core type: Drum Core, Wirewound
Shielding configuration: Unshielded
Operating temperature range: -40°C to 105°C
Self-resonant frequency: 55 MHz

Engineering Selection Recommendations

The CB2016T3R3M from Taiyo Yuden is a direct substitute for the obsolete L0806C3R3MPWST. Both components share identical electrical specifications for inductance, tolerance, and frequency characteristics. The substitute part provides superior current handling capability (800 mA versus 280 mA) and maintains mechanical and thermal compatibility through identical package dimensions and operating temperature range.

Both parts carry ROHS3 compliance certification and MSL 1 rating, ensuring regulatory and environmental compatibility in production environments. The substitute part is available in Tape & Reel packaging format, suitable for automated assembly processes.

The DC resistance specification of the substitute (260 mOhm maximum) is marginally higher than the original part (200 mOhm), remaining within acceptable tolerance for equivalent circuit performance in typical inductor applications.

Frequently Asked Questions (FAQ)

Q: Can the CB2016T3R3M be used as a direct replacement for the L0806C3R3MPWST in existing designs?

A: Yes. Both parts share identical inductance values, tolerances, package dimensions, and operating temperature ranges. The substitute part meets or exceeds all electrical and mechanical requirements of the original component.

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

A: The CB2016T3R3M is rated for 800 mA continuous current compared to the original 280 mA rating. This provides additional design margin and allows the substitute to operate safely in applications requiring higher current levels without thermal stress or saturation concerns.

Q: Does the higher DC resistance of the substitute part affect circuit performance?

A: The DC resistance difference (260 mOhm maximum versus 200 mOhm) represents a 30% increase. In applications where inductor losses are critical to circuit performance, this parameter should be evaluated against specific design requirements. For most general-purpose filtering and energy storage applications, this difference is negligible.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both the L0806C3R3MPWST and CB2016T3R3M conform to the 0806 (2016 Metric) package specification with identical length, width, and maximum seated height dimensions. They are mechanically interchangeable on PCB layouts.

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

A: The CB2016T3R3M is supplied in Tape & Reel (TR) format, standard for automated surface mount assembly processes. The original L0806C3R3MPWST packaging format is not specified in available documentation.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Yes. Both the L0806C3R3MPWST and CB2016T3R3M carry ROHS3 compliance certification and are classified as REACH Unaffected, meeting current environmental regulations for electronic component manufacturing and use.
