Substitute Part Grouping Explanation

Substitution of the LPWI201610TAR47T is determined by strict equivalence across the following parameters:

• Inductance value: 470 nH with ±20% tolerance
• Package / Case: 0806 (2016 Metric) surface mount form factor
• Shielding type: Shielded construction
• Operating temperature range: -40°C to 125°C minimum
• Current rating: Equal to or greater than 3.2 A
• DC resistance: Equal to or less than 40 mOhm maximum
• RoHS compliance: ROHS3 Compliant

The TFM201610GHM-R47MTAA meets all substitution criteria with improved electrical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The TFM201610GHM-R47MTAA from TDK Corporation is a direct substitute for the obsolete LPWI201610TAR47T. Both components share identical inductance values, package dimensions, and operating temperature specifications. The substitute part exceeds the original specifications in current rating (3.9 A versus 3.2 A) and saturation current (4.7 A versus 4.6 A), providing enhanced performance margin. DC resistance remains within acceptable tolerance (41 mOhm versus 40 mOhm maximum). Both parts maintain ROHS3 compliance and MSL 1 rating. The active product status of the TFM201610GHM-R47MTAA ensures long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the TFM201610GHM-R47MTAA be used as a direct replacement for the LPWI201610TAR47T?

A: Yes. Both components have identical inductance values (470 nH), tolerance (±20%), package form factor (0806 / 2016 Metric), and operating temperature range (-40°C to 125°C). The substitute part meets or exceeds all electrical specifications of the original component.

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

A: The primary differences are manufacturer origin and product status. The TFM201610GHM-R47MTAA offers higher current rating (3.9 A versus 3.2 A) and saturation current (4.7 A versus 4.6 A). DC resistance is marginally higher (41 mOhm versus 40 mOhm). The substitute part is currently in active production status.

Q: Are the physical dimensions identical?

A: Yes. Both components are packaged in the 0806 (2016 Metric) form factor with identical length (0.079"), width (0.063"), and maximum seated height (0.039"). They are mechanically interchangeable on PCB layouts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the LPWI201610TAR47T and TFM201610GHM-R47MTAA are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. Both carry EAR99 export classification.

Q: Is the higher current rating of the substitute part a concern for circuit compatibility?

A: No. Higher current rating indicates improved performance margin and does not create compatibility issues. The substitute part will function correctly in any application designed for the original component's 3.2 A rating.
