LBR2012T100M Equivalent & Substitute Parts

Part Overview

The LBR2012T100M is a 10 µH unshielded drum core wirewound inductor manufactured by Taiyo Yuden, rated for 150 mA continuous current with 360 mOhm DC resistance in a 0805 (2012 Metric) surface mount package. This component is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain flexibility, and support legacy system maintenance.

Substitute Part Grouping Explanation

Substitution eligibility for the LBR2012T100M is determined by strict equivalence across the following critical parameters: inductance value (10 µH), DC resistance (360 mOhm), package format (0805 / 2012 Metric), surface mount mounting type, ferrite core material, and unshielded configuration. The inductance tolerance (±20%) and self-resonant frequency (32 MHz) must remain consistent. Current rating and operating temperature range define the operational envelope; substitute parts must meet or exceed the original specification.

Two substitute parts are identified:

LSQEA201212T100M (Taiyo Yuden): Direct manufacturer equivalent with identical electrical specifications and active product status. This part represents the current production alternative within the same manufacturer's portfolio.

L0805R100MPWRT (KEMET): Cross-manufacturer substitute with matching inductance, DC resistance, package, and core material. Current rating is reduced to 125 mA (versus 150 mA original), and product status is obsolete. This part is suitable only where the lower current rating does not constrain circuit operation.

Engineering Selection Recommendations

Primary Substitute: LSQEA201212T100M

The LSQEA201212T100M is the recommended substitute for new procurement and design updates. This part is manufactured by Taiyo Yuden with active product status, ensuring long-term availability and supply chain stability. It provides complete electrical and mechanical equivalence to the LBR2012T100M, including identical inductance (10 µH), current rating (150 mA), DC resistance (360 mOhm), and package format (0805 / 2012 Metric). The extended operating temperature range (-40°C ~ 105°C versus -25°C ~ 105°C) provides additional thermal margin. Both parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Secondary Substitute: L0805R100MPWRT

The L0805R100MPWRT is a cross-manufacturer alternative from KEMET suitable for applications where current demand does not exceed 125 mA. This part maintains electrical equivalence in inductance, DC resistance, and self-resonant frequency. However, the reduced current rating (125 mA versus 150 mA) and obsolete product status limit its applicability to legacy system support only. The extended operating temperature range (-40°C ~ 105°C) and ROHS3 compliance are maintained. This part should not be selected for new designs or where circuit current requirements approach or exceed 125 mA.

Frequently Asked Questions (FAQ)

Q: Can LSQEA201212T100M be used as a direct replacement for LBR2012T100M?

A: Yes. The LSQEA201212T100M provides complete electrical and mechanical equivalence. Both parts share identical inductance (10 µH), current rating (150 mA), DC resistance (360 mOhm), package format (0805 / 2012 Metric), and core material (ferrite, unshielded). The LSQEA201212T100M has active product status, making it the preferred choice for ongoing production and design updates.

Q: What is the key limitation of the L0805R100MPWRT substitute?

A: The L0805R100MPWRT has a reduced current rating of 125 mA compared to the original 150 mA specification. This part is suitable only for applications where circuit current remains below 125 mA. Additionally, this part is classified as obsolete, limiting its availability for future procurement.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the 0805 (2012 Metric) surface mount package with identical physical dimensions (0.079" L × 0.049" W / 2.00 mm × 1.25 mm) and maximum seated height (0.057" / 1.45 mm). PCB footprints designed for the LBR2012T100M accommodate both substitute parts without modification.

Q: Do the substitute parts meet the same compliance standards?

A: Yes. Both LSQEA201212T100M and L0805R100MPWRT are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the original LBR2012T100M specifications.

Q: What is the difference in operating temperature range between the parts?

A: The LBR2012T100M operates from -25°C to 105°C. Both substitute parts extend the lower temperature limit to -40°C, providing a wider operating envelope (-40°C ~ 105°C). This extended range does not affect compatibility; circuits designed for the original temperature range operate within the substitute parts' specifications.

Q: Why is the LBR2012T100M marked "Not For New Designs"?

A: This designation indicates the part has been superseded in the manufacturer's product line. The LSQEA201212T100M represents the current production equivalent. For new designs and ongoing production, LSQEA201212T100M should be selected to ensure long-term supply availability and manufacturer support.
