Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LBR2012T470M is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 47 µH
• Inductance tolerance: ±20%
• Current rating: 75 mA minimum
• DC resistance: 1.7 Ohm
• Self-resonant frequency: 11 MHz
• Test frequency: 2.52 MHz

Mechanical Parameters:

• Package format: 0805 (2012 Metric)
• Mounting type: Surface Mount
• Core material: Ferrite
• Shielding configuration: Unshielded

Compliance Parameters:

• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Substitute parts must match all electrical specifications, maintain identical package dimensions and mounting characteristics, and satisfy the same environmental and regulatory compliance requirements. The LSQEA201212T470M meets these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The LSQEA201212T470M qualifies as a direct electrical and mechanical substitute for the LBR2012T470M based on complete parameter equivalence across all critical specifications.

Compliance Advantage: The LSQEA201212T470M carries an "Active" product status designation, whereas the LBR2012T470M is designated "Not For New Designs." Both components maintain ROHS3 compliance and identical MSL ratings.

Temperature Range Consideration: The LSQEA201212T470M supports an extended operating temperature range of -40°C to 105°C compared to the LBR2012T470M range of -25°C to 105°C. This extended lower temperature specification provides additional operational margin in applications requiring low-temperature performance.

Series Differentiation: The LBR2012T470M belongs to the LB, R Type series with drum core construction, while the LSQEA201212T470M belongs to the LSQE series with wirewound construction. Both configurations deliver identical electrical performance at the specified test frequency of 2.52 MHz and self-resonant frequency of 11 MHz.

Component selection between these parts should be based on procurement availability, supply chain continuity requirements, and design phase status. The LSQEA201212T470M is the preferred choice for new designs and ongoing production due to its active product status.

Frequently Asked Questions (FAQ)

Q: Can the LSQEA201212T470M be used as a direct replacement for the LBR2012T470M in existing assemblies?

A: Yes. The LSQEA201212T470M is electrically and mechanically equivalent to the LBR2012T470M. Both components share identical inductance values, current ratings, DC resistance, package dimensions, and mounting characteristics. No circuit modifications or PCB layout changes are required.

Q: What is the significance of the "Not For New Designs" status on the LBR2012T470M?

A: This designation indicates that the manufacturer has discontinued active development and promotion of this part number. The LBR2012T470M remains available for existing designs and legacy system support. For new product development, the LSQEA201212T470M is the recommended alternative due to its "Active" product status.

Q: Are there differences in the core construction between these two parts?

A: The LBR2012T470M features drum core construction, while the LSQEA201212T470M features wirewound construction. Both use ferrite core material and deliver identical electrical performance at the specified operating frequencies. The construction difference does not affect substitutability.

Q: Does the extended temperature range of the LSQEA201212T470M affect compatibility?

A: No. The LSQEA201212T470M operating range of -40°C to 105°C encompasses the LBR2012T470M range of -25°C to 105°C. The extended lower temperature specification provides additional operational margin and does not create compatibility issues in applications operating within the original temperature range.

Q: Are both parts available in the same packaging format?

A: Yes. Both the LBR2012T470M and LSQEA201212T470M are supplied in 0805 (2012 Metric) surface mount package format with Tape & Reel (TR) packaging. Physical dimensions and mounting characteristics are identical.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant, REACH unaffected, and carry MSL rating 1 (Unlimited). Both share identical ECCN (EAR99) and HTSUS (8504.50.8000) classifications.
