LB2016T1R0M Equivalent & Substitute Parts

Part Overview

The LB2016T1R0M is a 1 µH unshielded drum core wirewound inductor manufactured by Taiyo Yuden, rated for 490 mA continuous current with 90 mOhm DC resistance in a 0806 (2016 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 This component is classified as Not For New Designs, indicating it has been superseded in the manufacturer's product line.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 for ongoing production support, field repairs, and legacy system maintenance where the original part number may no longer be readily available or where design flexibility permits component substitution within specified electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitute parts for the LB2016T1R0M are identified based on matching or exceeding the following critical electrical and mechanical parameters:

Primary Matching Criteria:

• Inductance value: 1 µH
• Current rating: minimum 490 mA (or higher)
• DC resistance: 90 mOhm or lower
• Package / Case: 0806 (2016 Metric) or compatible surface mount package
• Operating temperature range: minimum -40°C ~ 105°C coverage
• Surface mount mounting type

Substitution Logic: Parts are grouped into two categories based on how closely they align with the original specification:

1. Direct Equivalent (LSQBA201616T1R0M): Matches all primary electrical parameters and package specification. Identical inductance, current rating, and DCR. Same operating temperature range. Represents the active production alternative from the same manufacturer.

2. Similar Equivalent (LQM21FN1R0N00D): Matches inductance value and surface mount package type but introduces trade-offs in current rating (220 mA vs. 490 mA), DC resistance (260 mOhm vs. 90 mOhm), package size (0805 vs. 0806), and operating temperature maximum (85°C vs. 105°C). This part is suitable only for applications where the reduced current capacity and higher DCR are acceptable.

Engineering Selection Recommendations

LSQBA201616T1R0M (Direct Equivalent - Recommended for Direct Replacement):

The LSQBA201616T1R0M is the primary substitute for the LB2016T1R0M. This part maintains identical electrical specifications (1 µH, 490 mA, 90 mOhm DCR) and package dimensions (0806 / 2016 Metric). Both components share the same operating temperature range (-40°C ~ 105°C) and are ROHS3 compliant with MSL 1 rating. The LSQBA201616T1R0M carries Active product status, ensuring ongoing availability and manufacturing support. This part is suitable for direct PCB layout substitution without design modification.

LQM21FN1R0N00D (Similar Equivalent - Conditional Substitution Only):

The LQM21FN1R0N00D from Murata Electronics shares the 1 µH inductance value and ferrite core material but introduces significant electrical and mechanical trade-offs. The current rating is reduced to 220 mA (55% of the original specification), DC resistance increases to 260 mOhm (nearly 3× higher), and the operating temperature maximum is limited to 85°C. The package footprint differs (0805 vs. 0806), requiring PCB layout modification. This part is Active and ROHS3 compliant but is suitable only for applications where the reduced current capacity and higher losses are acceptable. The shielded construction may provide EMI benefits in specific circuit topologies but is not equivalent to the unshielded original design.

Frequently Asked Questions (FAQ)

Q: Can LSQBA201616T1R0M be used as a direct replacement for LB2016T1R0M without PCB modification?

A: Yes. The LSQBA201616T1R0M is electrically and mechanically equivalent to the LB2016T1R0M. Both components have identical inductance (1 µH), current rating (490 mA), DC resistance (90 mOhm), package size (0806 / 2016 Metric), and operating temperature range (-40°C ~ 105°C). No PCB layout changes are required.

Q: What are the limitations of using LQM21FN1R0N00D as a substitute?

A: The LQM21FN1R0N00D has three significant limitations: (1) Current rating is 220 mA, which is 55% lower than the 490 mA rating of the original part, making it unsuitable for high-current applications; (2) DC resistance is 260 mOhm, approximately 2.9× higher than the 90 mOhm specification, resulting in increased power dissipation; (3) Package size is 0805 (2012 Metric) instead of 0806 (2016 Metric), requiring PCB footprint modification. This part is suitable only for low-current, low-power applications where these trade-offs are acceptable.

Q: Why does the LQM21FN1R0N00D have a lower operating temperature maximum?

A: The LQM21FN1R0N00D is rated to -40°C ~ 85°C, compared to -40°C ~ 105°C for the LB2016T1R0M. This is a material and design characteristic of the Murata multilayer inductor construction. Applications requiring operation above 85°C must use the LB2016T1R0M or LSQBA201616T1R0M.

Q: Are all three parts RoHS3 compliant?

A: Yes. The LB2016T1R0M, LSQBA201616T1R0M, and LQM21FN1R0N00D are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, suitable for standard PCB assembly and storage conditions.

Q: What is the difference between the drum core wirewound construction of LB2016T1R0M and the multilayer construction of LQM21FN1R0N00D?

A: The LB2016T1R0M uses a drum core wirewound design, where wire is wound around a ferrite core, providing high current capacity (490 mA) and low DC resistance (90 mOhm). The LQM21FN1R0N00D uses multilayer construction, where conductive layers are stacked, resulting in lower current capacity (220 mA) and higher DC resistance (260 mOhm). The wirewound design is more suitable for high-current, low-loss applications, while multilayer construction offers compact size and shielding benefits.

Q: Is the LSQBA201616T1R0M available in the same packaging format as the LB2016T1R0M?

A: The LB2016T1R0M is supplied in Tape & Reel (TR) packaging. The LSQBA201616T1R0M is also supplied in Tape & Reel (TR) packaging, ensuring compatibility with automated assembly equipment and standard component handling procedures.

Q: Can the shielded LQM21FN1R0N00D be used in place of the unshielded LB2016T1R0M for EMI reduction?

A: The shielded construction of the LQM21FN1R0N00D provides EMI containment benefits, but this part cannot be considered a direct substitute due to reduced current rating (220 mA vs. 490 mA), higher DC resistance (260 mOhm vs. 90 mOhm), and different package size (0805 vs. 0806). If EMI shielding is required, the circuit design must be evaluated to confirm that the reduced current capacity and higher losses are acceptable for the intended application.
