Engineering Selection Recommendations

Both the ASPI-0804T-330M-T and B82476B1333M100 are active production components with ROHS3 compliance and unlimited moisture sensitivity rating. The B82476B1333M100 provides superior electrical performance with a higher current rating (2.3 A versus 2 A) and lower DC resistance (88 mOhm versus 100 mOhm maximum). The substitute component also features an extended operating temperature range (-55°C ~ 150°C versus -40°C ~ 85°C) and a lower seated height (0.200" versus 0.205"), making it suitable for space-constrained applications. Both components maintain identical inductance values, tolerances, core materials, and physical footprints. The B82476B1333M100 carries AEC-Q200 automotive qualification, indicating enhanced reliability screening. Selection between these parts should be based on supply chain availability, cost considerations, and specific application temperature requirements.

Frequently Asked Questions (FAQ)

Q: Can the B82476B1333M100 be used as a direct replacement for the ASPI-0804T-330M-T?

A: Yes. Both components share identical inductance values (33 µH ±20%), core materials (ferrite unshielded drum core), physical footprints (0.510" L x 0.370" W), and mounting types (surface mount). The B82476B1333M100 meets or exceeds all electrical specifications of the ASPI-0804T-330M-T.

Q: What are the key differences between these two inductors?

A: The B82476B1333M100 provides enhanced performance with a higher current rating (2.3 A versus 2 A), lower DC resistance (88 mOhm versus 100 mOhm maximum), extended operating temperature range (-55°C ~ 150°C versus -40°C ~ 85°C), and lower seated height (0.200" versus 0.205"). The B82476B1333M100 also includes AEC-Q200 automotive qualification.

Q: Are the physical dimensions identical?

A: The length and width dimensions are identical (0.510" L x 0.370" W). The seated height of the B82476B1333M100 is slightly lower at 0.200" compared to 0.205" for the ASPI-0804T-330M-T, which is advantageous for compact PCB layouts.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the ASPI-0804T-330M-T and B82476B1333M100 have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage or handling.

Q: What is the significance of the AEC-Q200 rating on the B82476B1333M100?
