Substitute Part Grouping Explanation

Substitution of the LBR2012T101M is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Parameters (Must Match):

• Inductance: 100 µH
• Inductance Tolerance: ±20%
• Current Rating: 50 mA
• DC Resistance: 4Ω
• Core Material: Ferrite
• Shielding: Unshielded
• Self Resonant Frequency: 8 MHz
• Inductance Test Frequency: 796 kHz

Mechanical Parameters (Must Match):

• Package / Case: 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)

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The LSQEA201212T101M meets all specified electrical, mechanical, and compliance requirements and qualifies as a direct substitute.

Parameter Comparison

*The LSQEA201212T101M operates across an extended lower temperature range (-40°C vs. -25°C), providing broader environmental compatibility while maintaining the same upper temperature limit.

Engineering Selection Recommendations

The LSQEA201212T101M is the direct electrical and mechanical equivalent of the LBR2012T101M. Both components are manufactured by Taiyo Yuden and share identical inductance, current rating, DC resistance, core material, package dimensions, and compliance certifications.

Key Selection Factors:

1. Product Status: The LBR2012T101M is designated Not For New Designs, while the LSQEA201212T101M carries Active status. For new designs and ongoing production, the LSQEA201212T101M is the appropriate selection.

2. Compliance: Both parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating, ensuring regulatory and environmental compatibility across applications.

3. Operating Temperature Range: The LSQEA201212T101M extends the lower operating limit to -40°C compared to the LBR2012T101M's -25°C minimum. This provides enhanced performance in cold environment applications without compromising upper temperature performance.

4. Electrical Performance: All critical electrical parameters—inductance, tolerance, current rating, DC resistance, self-resonant frequency, and test frequency—are identical between the two parts, ensuring functional equivalence in circuit applications.

5. Physical Compatibility: Identical package dimensions, mounting type, and form factor ensure direct PCB layout compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the LSQEA201212T101M be used as a direct replacement for the LBR2012T101M in existing designs?

A: Yes. The LSQEA201212T101M is electrically and mechanically equivalent to the LBR2012T101M. All critical parameters—inductance, current rating, DC resistance, package dimensions, and compliance certifications—are identical. No circuit modification or PCB redesign is required.

Q: What is the difference between the LBR2012T101M and LSQEA201212T101M?

A: The primary differences are product status and operating temperature range. The LBR2012T101M is Not For New Designs, while the LSQEA201212T101M is Active.
