Engineering Selection Recommendations

Both the LLQPB201214T2R2MD and LSQPB201214T2R2MD are Active status products from Taiyo Yuden with full ROHS3 compliance and identical electrical specifications. Selection between these parts is based on availability and supply chain requirements rather than functional differences. The LSQPB201214T2R2MD series offers higher inventory availability (2851 pieces in stock versus 1007 pieces for the LLQPB series), making it suitable for high-volume production requirements. Both components satisfy identical application requirements for 2.2 µH inductance at 1 A rated current in 0805 surface mount packages. Compliance certifications, including RoHS3 and MSL Level 1, are equivalent across both part numbers.

Frequently Asked Questions (FAQ)

Q: Can the LSQPB201214T2R2MD be used as a direct replacement for the LLQPB201214T2R2MD?

A: Yes. Both components are manufactured by Taiyo Yuden and share identical electrical parameters, including 2.2 µH inductance, 1 A current rating, 143 mOhm maximum DC resistance, and 0805 package dimensions. The series designation difference (LSQP versus LLQPB) does not affect functional performance in the application.

Q: Are there any physical differences between these two inductors?

A: No. Both parts have identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and maximum seated height (0.055" / 1.40mm). They are mechanically interchangeable in 0805 surface mount layouts.

Q: What is the significance of the series designation change from LLQPB to LSQP?

A: The series designation reflects internal Taiyo Yuden product line organization but does not indicate functional differences. Both series employ identical ferrite core wirewound construction with equivalent electrical characteristics.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LLQPB201214T2R2MD and LSQPB201214T2R2MD are ROHS3 compliant, carry MSL Level 1 (Unlimited moisture sensitivity), and share identical ECCN (EAR99) and HTSUS (8504.50.8000) classifications.

Q: Which part should be selected for new designs?

A: Selection is based on supply chain and inventory considerations. Both parts are Active status and functionally equivalent. The LSQPB201214T2R2MD offers higher current inventory availability.

Q: Are the saturation current specifications identical?

A: Yes. Both inductors have a saturation current (Isat) of 1.1 A, indicating identical core saturation behavior under load conditions.

Q: What is the operating temperature range for both parts?

A: Both the LLQPB201214T2R2MD and LSQPB201214T2R2MD operate across -40°C to 105°C, providing identical thermal performance specifications.

Q: Can these inductors be used in high-frequency applications?

A: Both parts have a self-resonant frequency of 350 MHz, making them suitable for applications up to this frequency limit. Inductance is measured at 1 MHz test frequency.
