Key Parameters

Substitute Part Grouping Explanation

Substitution of the LB2012T100M is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 10 µH
• Inductance tolerance: ±20%
• Current rating: 120 mA minimum
• DC resistance: 700mOhm
• Self resonant frequency: 32 MHz
• Test frequency: 2.52 MHz

Mechanical Parameters:

• Package type: 0805 (2012 Metric)
• Mounting type: Surface Mount
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Maximum seated height: 0.057" (1.45mm)

Environmental & Compliance Parameters:

• Core material: Ferrite
• Shielding: Unshielded
• Operating temperature range: -25°C minimum to 105°C maximum
• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must match all electrical specifications, maintain identical package dimensions for PCB layout compatibility, and satisfy all environmental and regulatory requirements. The LSQBA201212T100M meets these criteria as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The LSQBA201212T100M is a direct electrical and mechanical equivalent to the LB2012T100M. Both components are manufactured by Taiyo Yuden and share identical specifications across all critical parameters: inductance value, current rating, DC resistance, package dimensions, and environmental compliance ratings.

The primary distinction is product status: the LB2012T100M is classified as Not For New Designs, while the LSQBA201212T100M carries Active status. This indicates the LSQBA201212T100M represents the current production equivalent within Taiyo Yuden's inductor portfolio.

The LSQBA201212T100M provides an extended operating temperature range of -40°C to 105°C compared to the LB2012T100M's -25°C to 105°C specification. This extended lower temperature capability presents no compatibility constraint for applications originally designed for the LB2012T100M.

Both components satisfy ROHS3 compliance and maintain identical moisture sensitivity levels (MSL 1 - Unlimited), ensuring equivalent handling and storage requirements. The 0805 (2012 Metric) surface mount package ensures direct PCB layout compatibility without design modifications.

Frequently Asked Questions (FAQ)

Q: Can the LSQBA201212T100M be used as a direct replacement for the LB2012T100M in existing designs?

A: Yes. The LSQBA201212T100M is electrically and mechanically equivalent to the LB2012T100M. All critical parameters—inductance, current rating, DC resistance, package dimensions, and operating temperature range—are identical or superior. No circuit modifications or PCB layout changes are required.

Q: What is the difference between the LB2012T100M and LSQBA201212T100M?

A: Both components are 10 µH unshielded wirewound inductors with identical electrical specifications and 0805 (2012 Metric) packaging. The primary difference is product lifecycle status: the LB2012T100M is Not For New Designs, while the LSQBA201212T100M is Active. The LSQBA201212T100M also offers an extended lower operating temperature limit of -40°C versus -25°C.

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

A: Yes. Both the LB2012T100M and LSQBA201212T100M measure 0.079" L x 0.049" W (2.00mm x 1.25mm) with a maximum seated height of 0.057" (1.45mm). They are fully compatible with the same PCB footprints and assembly processes.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). They satisfy equivalent environmental and regulatory requirements.

Q: Why would I choose the LSQBA201212T100M over the LB2012T100M?

A: The LSQBA201212T100M should be selected for new designs and ongoing production because it carries Active product status, ensuring long-term availability and manufacturer support. The LB2012T100M's Not For New Designs classification indicates limited future availability. The LSQBA201212T100M also provides extended low-temperature operation (-40°C minimum).

Q: Are there any performance differences in inductance or current handling?

A: No. Both parts deliver identical inductance (10 µH ±20%), current rating (120 mA), and DC resistance (700mOhm). Self-resonant frequency and test frequency specifications are also identical at 32 MHz and 2.52 MHz respectively.

Q: What is the packaging format for both parts?

A: Both the LB2012T100M and LSQBA201212T100M are supplied in Tape & Reel (TR) packaging, standard for surface mount component distribution and automated assembly processes.
