L0806C2R2MPWST Equivalent & Substitute Parts

Part Overview

The L0806C2R2MPWST is a 2.2 µH unshielded drum core wirewound inductor manufactured by KEMET in the 0806 (2016 Metric) surface mount package. This component is rated for 315 mA continuous current with 130 mOhm DC resistance 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 production and maintenance applications. Substitute parts must maintain electrical performance characteristics including inductance value, current rating, DC resistance, and physical package dimensions to ensure direct board-level compatibility.

Substitute Part Grouping Explanation

Substitute parts for the L0806C2R2MPWST are identified based on strict electrical and mechanical parameter matching within the wirewound inductor category. The substitution criteria are:

Primary Matching Parameters:

• Inductance value: 2.2 µH
• Inductance tolerance: ±20%
• DC resistance: 130 mOhm
• Package / Case: 0806 (2016 Metric)
• Core material: Ferrite
• Shielding configuration: Unshielded
• Mounting type: Surface Mount
• Operating temperature range: -40°C to 105°C

Secondary Compatibility Parameters:

• Self resonant frequency: 70 MHz
• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must accommodate the original 315 mA current rating or exceed it. Parts meeting all primary parameters are classified as direct functional equivalents suitable for board-level replacement without design modification.

Parameter Comparison

Engineering Selection Recommendations

The LB2016T2R2M manufactured by Taiyo Yuden qualifies as a direct functional equivalent to the obsolete L0806C2R2MPWST. Both components share identical electrical specifications for inductance, tolerance, DC resistance, and frequency characteristics. Physical dimensions and package footprints are identical, enabling direct PCB-level substitution without layout modification.

The LB2016T2R2M provides a higher current rating of 375 mA compared to the original 315 mA specification, offering improved thermal margin in applications operating near the original current limit. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification (MSL 1), ensuring compatibility with standard manufacturing and storage protocols.

The LB2016T2R2M is classified as "Not For New Designs" by Taiyo Yuden, indicating it remains available for legacy system support and maintenance applications. Selection of this substitute should be based on application current requirements and availability constraints specific to your supply chain.

Frequently Asked Questions (FAQ)

Q: Can the LB2016T2R2M replace the L0806C2R2MPWST in existing designs?

A: Yes. The LB2016T2R2M is electrically and mechanically compatible with the L0806C2R2MPWST. Both components share identical inductance values, DC resistance, package dimensions, and operating temperature ranges. No PCB modifications are required for substitution.

Q: What is the significance of the higher current rating on the LB2016T2R2M?

A: The LB2016T2R2M is rated for 375 mA continuous current versus 315 mA for the L0806C2R2MPWST. This higher rating provides additional thermal headroom in applications operating near the original current specification. The substitute part will not degrade performance in circuits designed for the original 315 mA rating.

Q: Are there packaging differences between these parts?

A: No. Both the L0806C2R2MPWST and LB2016T2R2M use the 0806 (2016 Metric) surface mount package with identical physical dimensions of 2.00mm length by 1.60mm width and 1.80mm maximum seated height. Tape & Reel packaging for the LB2016T2R2M does not affect component performance or board-level compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity classification. They meet identical environmental and regulatory requirements for manufacturing and storage.

Q: What is the inductance tolerance specification for both parts?

A: Both the L0806C2R2MPWST and LB2016T2R2M carry ±20% inductance tolerance at the specified test frequency of 7.96 MHz. This tolerance applies equally to both components and must be considered in circuit design calculations.

Q: Are there any frequency-dependent differences between these inductors?

A: No. Both parts exhibit identical self-resonant frequency of 70 MHz and are tested at the same frequency of 7.96 MHz. Frequency response characteristics are equivalent across the operating bandwidth.
