Engineering Selection Recommendations

The LSQPB201210T1R0M is the qualified substitute for the BRL2012T1R0M based on the following engineering criteria:

Electrical Equivalence: Both components deliver identical inductance (1 µH), current rating (850 mA), DC resistance (175.5 mOhm max), and frequency characteristics (300 MHz self resonant frequency). The ±20% tolerance specification is matched across both parts.

Mechanical Compatibility: Both inductors are packaged in the 0805 (2012 Metric) surface mount form factor with identical physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and maximum seated height (0.039", 1.00mm). Direct PCB footprint compatibility is confirmed.

Thermal and Environmental Performance: Operating temperature range (-40°C to 105°C) is identical. Both components maintain MSL 1 (Unlimited) moisture sensitivity rating and are ROHS3 compliant.

Product Status Advantage: The LSQPB201210T1R0M carries "Active" product status, indicating ongoing manufacturer support, continued availability, and compliance with current regulatory standards. The BRL2012T1R0M "Not For New Designs" status necessitates transition to the substitute part for long-term design sustainability.

Regulatory Compliance: Both parts maintain identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8504.50.8000), ensuring no compliance complications during substitution.
